Thinking about electric assist

Okay on the flats, but for the hills we'll need more power

If I could name the #1 thing that makes parents we know in San Francisco who’ve never attempted family biking perk up and say they want to try, it is the words “electric assist.” The other week I said those words in passing to another mom at our daughter’s preschool who has almost no experience riding. She has now told me every day that I’ve seen her since that she is hounding her husband to shop for an electric bike for them when he returns from his current business trip.

Discussions about riding bikes in San Francisco always involve hills, to some extent. This is especially the case if you live, as we do, on a mountain. Mt. Sutro: it’s right there in the name. It burns us, Precious! We’ve learned to ride them, but these hills aren’t easy. If we lived higher up the mountain like some of our neighbors, I would be riding an electric bike right now. Nonetheless hills are at least consistent. Unlike the wind or the traffic, they are predictable. They aren’t going anywhere. I keep thinking that people can get used to anything, but there are destinations in the city we avoid unless we’re driving. And there are times we give up. Last weekend Matt couldn’t face the prospect of riding to the hardware store, which is halfway up the other side of our hill, leaving him the unenviable choice of riding up and down and back, or down and up and back, or driving. Despite the hell that is finding parking in that neighborhood, he drove.

It's easier on the way down

Our friends have a Big Dummy to take their kids to school, and they live on Lone Mountain. They take their kids, their groceries, and on occasion each other, up Lone Mountain. And they tell me they push that bike a lot. They are philosophical about it and call it upper body training. They are opposed to many electric assists for environmental reasons, but they are the exception. Our friends who live on Potrero Hill or nearer the top of Mt. Sutro have said they’d be riding their bicycles daily if they had any idea how to arrange an assist. I myself had no idea. But our kids are getting heavier, and I think it’s time to learn. The only other semi-practical option was suggested by my brother-in-law, who noted that Lance Armstrong became a much better hill climber after getting cancer and losing 20 pounds. I suppose that I could conceivably hack weight off my own frame for a year or so at the same rate my kids were gaining without losing much leg strength. But as a woman in America I really don’t need any more reasons to obsess about body weight, and this strategy would only work for so long anyway.

Option #1a: Buy a new electric bike. There is a new shop (and some established ones) in San Francisco dedicated to electric bikes. But when I look at their bike lines, they do not seem practical for family use. Most seem to lack basics like rear racks, and overall remind me of the Bikeyface cartoon about “ordinary black lace panty” bikes (not that there’s anything wrong with that). Perhaps one day this will change.  But the word on dedicated electric bikes is that the bikes themselves are often cheaply made. To keep the price point less terrifying, the money is in the motor.

Option #1b: Buy a new electric cargo bike. Both Kona and Yuba make electric cargo bikes, the Electric Ute and the El Mundo, respectively. These are obviously suited to family use, and they are both respectable manufacturers who primarily make bikes rather than slapping some bike components onto a motor. These bikes are expensive relative to the non-electric versions (all electric bikes are expensive) but they seem to offer some economies of scale; the electric versions cost less than it would cost to buy a non-electric version and add a comparable motor to it. If you’re looking for a new cargo bike, these seem like competitive options. However we have a cargo bike that we like, and living in the city makes us reluctant to commit to a really long bike like the Ute or the Mundo.

Option 2: Add a motor to the bike. This is the direction we’re leaning if we electrify: we have bikes we like right now, and if we wanted to upgrade/change bikes later, we could move the motor, potentially sparing ourselves the cost of upgrading more than once. But the market for add-on electric assists is massively confusing to me. Older reviews suggest that some manufacturers offered pedal assist (e.g. BionX, Stokemonkey) and some offered throttle assist (e.g. eZee, nearly everyone else). Not sure what’s up with the random capitalization by these manufacturers. What that means as I read it:

  • pedal assist motors make you stronger as you pedal, but won’t work unless you’re pedaling
  • throttle assists operate with a switch on the handlebars and move the bike along whether or not you’re pedaling.

But evidently this is moot now because primarily pedal-assist motors now offer the option of moving your bike whether or not you’re pedaling (BionX) and primarily throttle assist motors now offer what some are calling “the European option” of only working when you’re pedaling (eZee), a term which I can only assume refers to some legal restriction on electric assist bikes in Continental locales. As a bonus, the major brands all seem to offer head and tail lights that plug into the battery. Whoo hoo!

As a result I have started thinking about electric assists in the simplest possible terms for a total noob like me: front wheel, back wheel, and inbetween.

Front wheel motors

You can buy these all over the place, including on Amazon; eZee is apparently the market leader. The El Mundo uses an eZee motor; some models are evidently powerful enough to move a loaded cargo bike. An important caution: You shouldn’t put a front wheel motor on an aluminum front fork. It will break while you’re riding and fling you headfirst onto the ground. GOOD TO KNOW! This is mentioned occasionally on sources like online bicycle forums and on the websites of what appear to be reputable electric bike shops, but is not routinely mentioned in the advertising for these motors. The electric assist market is a Wild West indeed.

Costs for these motors seem to range from $400 or so for a low-power version with heavy batteries (not cargo-bike friendly) to $1500 or so for a high-torque version with lighter weight batteries. Installation not included, and given that people are evidently mounting them on aluminum forks on occasion, I would be inclined to find a reputable bike shop for installation even if I weren’t hopelessly unhandy. Who knows what else could go wrong?

The Kona has an aluminum fork: no front wheel motor on our MinUte. The Breezer has a steel front fork (the specs said “chromoly” which I had to look up, because in case it’s not totally clear by now, I’m clueless; another option is to see if a magnet sticks to your fork, if yes, your fork is steel). So we could put a front wheel motor on the Uptown.

Rear wheel motors

The market leader in rear wheel motors is apparently BionX. It is primarily a pedal assist motor, but the newer versions claim you can use it without pedaling if you want. The BionX motor comes in various powers, some suitable for cargo bikes and hills, others less so. BionX appears to be sort of the Apple of electric assists; expensive and incompatible with other systems, but stylish and easy to use. The newest versions have cool features like locking the rear wheel when you walk away with the console, making the bike more difficult to steal.  Reviews suggest that riding with the BionX is a lot of fun; you pick a level of assist (25% extra to 300% extra) and when you push down hard on the pedals, the battery sends out that much extra power to make riding easier. This would be super-handy at stop lights as well as on the hills. This motor only works on bicycles that use a derailleur on the rear rather than an internally geared hub.

Cost seems to range from $1000 for a system that might not move a loaded cargo bike uphill to $2000 for the top-of-the-line system with lots of torque and security features, installation not included.

My Breezer has an internally geared hub and I like it: no BionX for the Uptown. The Kona MinUte has a derailleur so we could put a rear wheel motor on it. How can you tell if you have an internally geared hub? It’s like true love; you already know.

Inbetween

Let’s say you have an aluminum front fork and an internally geared hub and no desire to buy a new bike. Or you are carrying very heavy loads. Apparently there are also motors called mid-drive motors that attach to the chain. They are recommended for cargo bikes because they have a lot of torque. The only two I have heard of are the EcoSpeed and the now-out-of-production Stokemonkey. The Stokemonkey, if it were possible to find one used, is pedal-assist only (a discussion of the pros and cons of this for one family, relative to the eZee kit, is here). And evidently really, really powerful; it took a loaded cargo bike up Russian Hill! That’s over a 30% grade.

Costs are heart-stopping even for electric assists. The EcoSpeed runs over $3k. Installation is evidently challenging. It’s not for the faint of heart, unless of course you live in Portland, where all these motors are made, and where presumably any bike mechanic could install one with their eyes closed in exchange for a pint of artisanal beer sold from a Metrofiets.

Should we get an electric assist? I don’t know. They’re expensive, and that’s daunting. But we’d probably ride a lot more, and that is worth something too. We fear the hills more and more as the kids grow. We are fortunate that there are at least bike shops in San Francisco that seem to specialize in electric motors. Both Big Swingin’ Cycles and The New Wheel will put a BionX on a bike, and Electric Bicycle Outlet will install an eZee kit. Maybe it’s time for us to actually visit one of them.

If you lived here, you’d be home now

An intrepid rider in the Tenderloin--she was moving very fast

Recently I read a fascinating piece on the evolution of pedestrian and traffic rights. There was, evidently, once a time when the road was reserved primarily for the use of street cars and pedestrians. Automobiles were an unwelcome intruder on this territory, mowing down children with the temerity to play in the street as they had for centuries. The article claimed that the automobile industry at the time responded to the resulting public outrage by literally rewriting the rules of road, creating the idea that pedestrians should be confined to crosswalks, and that anyone who dared use the roads as they always had was a rube. This was before my time.

I am recent convert to riding my bicycle but a lifelong pedestrian, as we almost all are, albeit some of us in much more limited doses. I live in a large city, so the “couch to garage to garage to store” experience is rarely an available option. But I have lived in the suburbs, although I found the experience confining. And even in suburbs designed around the car, people walk in traffic, if only through parking lots. People are, at root, pedestrians. My children learned to walk before they could speak.

Tandems and surreys and bicycles, oh my! A quiet Sunday in Golden Gate Park

It was difficult for me to imagine a road without the right of way for cars. San Francisco offers many weekends where the streets are closed to cars in Golden Gate Park and for Sunday Streets, but although these are entertaining, they are places and times when cars are entirely absent. (And despite people’s avowed affection for their own cars, these events are very, very popular.) I cannot imagine a city where cars were still there, but placed on an equal footing with other road users. I think I would like that world.

San Francisco does, however, have a place where pedestrians act as though they lived in that world. That place is the Tenderloin. The Tenderloin is a grim wasteland in the middle of San Francisco. It is not just possible but probable that you will see people on the sidewalk  shooting up while walking through, something that despite years of working with needle exchanges, I had rarely seen done without apology or restraint under the open air before moving to San Francisco. One evening when Matt and I were walking through the Tenderloin to a concert, a man walked up carrying a mattress, dropped it heavily on the ground in front of us, and then passed out on top of it. I have spent more time in the Tenderloin lately as part of my increased work with homeless shelters, which are packed into this part of the city as though they were kennels.

These pedestrians entered the intersection after the light turned green and crossed at their own measured pace

In the Tenderloin pedestrians largely treat traffic signals as optional, whether due to despair or to drugs. It’s rare that I’m willing to ride my bicycle in the Tenderloin (it would be stripped if I parked it), but I do walk there when I have meetings in the area and on occasion we drive through. And one thing you notice immediately is that drivers are typically more cautious, as a green light in the Tenderloin does not necessarily mean go. People wander out into the streets whenever they reach a corner whether or not the light is favorable, or to chat when the sidewalks get crowded. Cars tend to move very slowly. Admittedly some of them are looking to score. When I am driving through I move with the same slow caution, although I have no desire to purchase street drugs or sex. My caution is by no means universal—pedestrians are killed by drivers in this area frequently—but it is a different experience to drive and walk there than it is in other neighborhoods. Walking there is not necessarily better: the entire neighborhood reeks of waste, catcalls and propositions are inevitable, and the weight of human despair can be overwhelming. But the omnipresent threat of cars is somewhat lighter. Driving is fine as long as you’re not in a hurry. I have learned to accept this but people often freak out while driving through the Tenderloin, and these people usually want to leave in a hurry.

I do not think about the Tenderloin when I think about safe streets. Like everyone else who does not default to car travel, I imagine a world where drivers were at least prosecuted for killing pedestrians or cyclists, although most cities in the United States apparently feel that this is too much to ask. When I am ambitious I imagine San Francisco with an overlay of Copenhagen. I still miss the experience of moving through Copenhagen, which felt both liberating and safe. It was in many ways the friendliest place we have ever been, and I don’t doubt that that was related to the bicycles; most of the city felt scaled to people.  I like to imagine the city’s streets being quiet enough to hold a conversation with my son when we are walking through a crosswalk. San Francisco’s major streets are painfully noisy. I often imagine a night without the howl of car alarms or the blatting of motorcycle pipes. These are pleasant fantasies.

But in some ways, I realize that the Tenderloin represents a different approach to the same problem, an escalation of pedestrian demands for the right to safe streets. It is a terrifying thing to watch; in the inevitable cross-fire, a car might get dinged but the pedestrian is usually killed. Very few people would be willing to take the same risks unless they too had nothing to lose. I find my time in the Tenderloin increasingly fascinating because it reflects not only the needs of desperate people, but of the costs of transportation design that ignores actual residents entirely.

Scofflaws

Driving to ride a bicycle. This makes no sense to me.

My commute to work and back is largely on a quiet bike lane, a broad road with surprisingly few cars and a large collection of bicycles. Based on the clothing choices of the riders and the crust of mirrors, panniers, and lights on the bikes, I presume these fellow road users are all headed to office and teaching jobs like mine. Even on the (slight) downhills, we all proceed at the measured pace that suggests that in all likelihood, none of us got a full night’s sleep, as is SOP in a household with children under the age of five.

Every once in a while, however, the smooth road, limited elevation changes, and infrequent traffic signals seem to draw a different kind of rider on our evening ride home, a type displaying substantially more ambition. The other day as I left my office I met with a pair of riders in the full lycra kit, riding bicycles that to my eyes looked as though they might collapse in a stiff wind. From the moment we converged they showed evidence of having arrived from a different planet, one without traffic signals. They blew through every stop sign without even slowing down or taking a break in their chit chat, even when other cars or bicycles were patiently waiting their turns. They paid only slightly more attention to red lights, slowing on occasion but otherwise treating them a polite suggestion to be aware of fast-moving traffic while crossing.

Traffic scofflaws, whether in cars or on bikes, annoy me (and everyone else). Even worse is when the people in question are as slow as I am, and this is pretty slow, as I am opposed to sweating when I can possibly avoid it. At the very least, if you are going to blow through red lights, you should have the decency to go fast enough that I’m not stuck behind you for over a mile. And I was in fact stuck behind these tiresome riders, who were riding side-by-side to prevent boring, law-abiding commuters from passing. What is it with lycra?

An outfit I cannot imagine wearing

There are, I’ll admit, a few lycra-clad riders who seem aware of the rules of the road. Occasionally on my ride home I will see a man in lycra who is 70 years old if he is a day, riding a bicycle that was evidently designed to go fast, although I have yet to see evidence of this actually happening. This lovely man is still having a bit of trouble with this bicycle, and it is painful at times to watch him stop carefully at every intersection, as clipping his shoes into and out of his pedals is not something he’s fully mastered yet. But I respect his effort and will ride more slowly than usual when I am behind him, as I figure he can use all the encouragement he can get, and being passed by a mom in dress clothes on a cargo bike with a kid on the back is probably something of a blow to the ego. So I usually wait until he’s having more trouble with the pedals than usual at a stop light to pass.

This is my kind of ride.

One of the advantages of riding around with major weight on my bike is that I have gotten much stronger, although I am slow. This pays off in a big way on the hills, especially on the occasions when I am riding without my kids. On the day I was stuck behind the annoying roadie couple, I was riding alone. And after a mile or so of mostly flat riding, we finally hit a real hill. The two of them split to crunch up it slowly on bicycles that weighed less than my pannier, standing in the pedals for leverage. So I passed them. Next time bring your “A” game, roadies.

Loaner bike: The Yuba Mundo v4 (hello, goodbye)

Two cargo bikes squeeze into a bike rack...

Last night the loaner Yuba Mundo went home to Marin. It was fun while it lasted. I had, until a couple of weeks ago, never ridden a real longtail before, and as I’ve mentioned, it takes some getting used to. Our friends who were used to riding a Surly Big Dummy liked it a lot. “It carries three kids and you don’t even notice! And it’s cheap!” They are, of course, very used to riding with two kids on the back. In fact they rarely do anything else. My brother-in-law hated the Mundo. “I hate this bike,” he said. It was unclear whether it was the bike itself or the experience of riding any kind of long bike with two kids on the back. With hindsight I lean toward the latter.

After riding it for two weeks, the Mundo grew on me. I conclude after this experience that big bikes have a significant learning curve. If you’re in the market for one, especially as a first bike, it’s something to consider. A case in point: I dropped the Mundo with both kids on it. In front of our local bike shop. The bike shop guys ran out in horror and offered us their shop Ute as a loaner to get home. It was mortifying. At first I thought it was just me, so it was reassuring to hear from Family Ride and A Simple Six that this is one of those things that just happens sometimes. The kids were unharmed although startled. I now put this experience in the same category as dropping the baby off the bed. When I was in grad school my advisor told those of us who were expecting that one day, a while after our kids were born, we would put them on the bed and they would roll off. “It happens to everyone,” he said. “I’m telling you now so you don’t beat yourself up about it. They’ll be fine.”

Fully loaded

I really liked having the ability to carry two kids and a load of groceries in San Francisco (and this is particularly appealing for younger kids who need child seats). It is pretty amazing. People who live in flat areas with no hills to speak of love their box bikes (bakfiets, Madsens), but almost everyone agrees that those bikes won’t climb real hills, and getting down them on the other side raises safety issues. San Francisco has real hills. The Mundo may be heavy, but it cranks up the hills; I never had to walk it. Based on our experience so far, I now believe that people who live in hilly terrain should buy bikes from companies based in the San Francisco Bay Area, or maybe Seattle.

(There is evidently one exception to the “box bikes won’t climb” rule, the custom Metrofiets. Down in SoCal, Bike Temecula is riding a Metrofiets with a BionX electric assist. Although that bike is unquestionably one of the coolest things I’ve ever seen on two wheels, it is not cheap. A Metrofiets with kid seats costs $5k WITHOUT the electric assist [update: Metrofiets notes below that the price is just under $4k; Splendid Cycles lists the box with child seat as an add-on for $665 and a harness as an add-on for $100]. We could buy normal bikes with electric assists for everyone in our family for that kind of cash. Or a used car, were we so inclined, which we are not. Where we’d store any of those things is a different question entirely.)

There are things I would change about the Yuba Mundo. My personal pet peeve is dynamo lights; I think all family bikes should have them, and the Mundo does not (it’s not even an option). In San Francisco, the bike should be fitted with disc brakes (this is an option, and not an expensive one, either). The child seat mount would be infinitely better if it were possible to slide the seats forward and back, possibly on rails? I would have preferred the Peanut seat about 6 inches forward from where it was, because it leaned beyond the rear tire, which made the bike wag. And when I had only my daughter on board, I would have liked to slide it all the way forward, which would have made it much easier to get up steep hills and to talk to her.

There are also a lot of things to like about this bike just as it is. It can move major-league weight, way more even than other long tail bikes. And you don’t even feel it except at the starts and stops. This is pretty amazing, especially considering the weight of kids and their gear. My two kids together are ~80lbs stark naked, but outside the house they always have clothing on, and on any kind of trip we add in lunches and book bags and toys. The weight adds up fast, particularly if you want to stop and pick up groceries. (And if the weight gets out of hand as the kids get older, Yuba sells an electric version, the elMundo.) The Bread Basket was unnerving to ride with at first, but absolutely awesome. When it was loaded up I barely noticed riding over potholes or Muni tracks. Our son loved the soft seat cushion and wants one for the MinUte. And the bike acoustics are good; this may sound like an odd concern, but it’s useful to be able to hear the kid in the back. Our kids liked riding on this bike. They called it The Beast.

Yuba sometimes bills the Mundo as a minivan replacement, but I don’t quite agree with that. Minivans are plusher. The Mundo reminds me more of a pickup truck; stripped down but effective at moving stuff where you need to go. Yuba is like the Ikea of bicycle manufacturing, peeling off everything optional to keep the bike at a price point that does not make novice riders laugh in disbelief. As long-term recovering cheapskates (we’re so cheap that we bought our Ikea furniture on craigslist, given that the kids are going to trash it anyway), I like that there’s a cargo bike manufacturer with this business model.

In contrast, a bike like the Surly Big Dummy is more of a station wagon concept car, which can be customized to do anything you want, but only if you know what to ask for and can swallow the price. The minivan of bikes is the box bike.

Classic San Francisco pinch point

Would we get a Mundo? No, but that’s not a knock against it, but a statement about our lifestyle. We wouldn’t get a Mundo for the same reason we don’t have a back yard. We’ve made a choice to live in a large city, and that choice involves some compromises. We have, by city standards, amazing bicycle storage, but even we had to rearrange that space around the Mundo.  San Francisco has serious traffic, and maneuvering a big bike through it led to some frustrating moments; another bike would whiz through a pinch point in front of me, and I would realize I had to wait until it cleared. Parking the bike, even at bike racks, always involved a little jiggering around tight corners and other bikes—I was in that situation when the Mundo fell over. There is a lot of starting and stopping in the city, and that is difficult with a heavy bike. The Kona MinUte, we’ve realized, may represent the outside range of bikes that we can handle in San Francisco. I wasn’t surprised when the Yuba rep told me that most of their customers lived in inner-ring suburbs or smaller cities. That seems like this bike’s ideal stomping ground. The Costco run holds no fears for the Mundo.

We are lucky devils indeed to live in San Francisco, and being shut out of a few categories of bicycle seems like a small price to pay for the privilege. I’m glad we had the chance to try the Yuba Mundo, and although we won’t miss figuring out where to put it, all of us, especially the kids, will miss having the chance to ride it sometimes.

Riding to school on the Bobike Junior

A while back Matt tore a muscle in his calf, and he’s been limping around ever since. He can walk short distances, but ideally wouldn’t be walking as much as he is, and that’s slowed his recovery. He hasn’t been able to ride his bike for at least two weeks. He’s not happy about it.

Headed for the big hill on the Bobike Junior

Our son’s school is on the way to Matt’s office (more or less) so normally they ride together, Matt drops him off, then continues on to work. He also typically does the pickup at after-school, and they ride home through Golden Gate Park. The MinUte is always ready to pop a kid (or even two, if they’re old enough to hold on) on the back.

So for the last couple of weeks, I have been doing most of our son’s drop-offs and some of the pickups. It’s been nice to have this extra time with him in the morning. I hadn’t used the Bobike Junior regularly; it pops on and off the bike in less than a minute, and for regular commutes it is mostly off. But for the last week it has been on my bike full-time. On our morning rides, we bomb down the hill from our house as a starter (no worries: the neighbors already have Child Protective Services on speed dial) and head into Golden Gate Park, over to the Panhandle, then up to Alamo Square and back down to Japantown. This is a very cool ride; in the early morning, when it’s still half-light, the park is still thin on other bicycle commuters and the trees hide the car traffic on either side.

Waiting for the light in the panhandle

Our son can be very chatty on the bike, and he enjoys the view. He is sometimes irritated by the pannier encroaching on his foot rest, and the other day, he entertained himself by lightly kicking my calf on every pedal stroke. “I don’t want to ride with the pannier again!” he yelled. “I don’t want to shove a backpack in your face,” I answered. I forget what else we talked about, and now only remember that we were laughing so hard that we were bothering the joggers, who normally reside exclusively in iPod land. We learned later that one of his classmates saw us while driving by (we arrived at school only a minute later than they did, which still astonishes me). Her dad told me that she asked why she couldn’t ride to school too.

I like the way the Breezer takes the hills, so when we’re headed up to Alamo Square and the lights are timed right, we can jump up the incline pretty fast. That day we raced a garbage truck. We lost, but held our lead for longer than I expected, given that I had a 1st grader and his school gear on the back.

The loathsome eastern approach to my office

After his drop-off I head up to work, taking the grim eastward approach to Laurel Heights, which packs all of the elevation in at once at Post Street, then drops me off at the intersection of California and Presidio, a nightmarish snarl that usually leaves me walking my bike through the intersection rather than attempting to ride it. Thank goodness I have a step-through frame: hit the red light, slither off to one side, walk the bike through the crosswalks, hop back on.

People always ask me whether the folded Junior is a battery pack

I am still vaguely amazed that a seat like the Bobike Junior even exists. It solves an unusual problem; most parents with kids our son’s age would have them riding to school on their own bikes. Traffic and hills and the transition to after-school make that impossible for us, but I don’t think our situation is exactly typical. And yet thanks to the canny Dutch, we’ve found an out-of-the-box solution that’s both effective and a lot of fun.

These are the ways we ride to school

First day of first grade

We have found that our son’s elementary school contains an embarrassment of riches (for the record, this is an under-enrolled Title I public school in San Francisco, not the usual candidate for perceived awesomeness, a complete sleeper of a school). These riches extended, we learned this year, to a range of bicycle commute strategies with kids.

Bicycle commuting to school in San Francisco is not like it is in other locales. Kids enrolled in lower grades can’t usually ride on their own, due to traffic and hills and distance; this is a citywide school, and some families are coming from quite far away. Moreover, the after-school programs at our school are mostly off-site, and students take the bus from the school, meaning that there’s no way to take a kid’s bike along after school lets out. Finally, we haven’t yet had bike racks installed at the school (we’re on the list) so there’s no place to leave a bike even if kids could ride. The teachers who ride bring their bikes into the school building, but this isn’t something that would work for a bunch of kids.

So typically we all have to ride with the kids with us somehow, and as I’ve mentioned before, city people rarely use trailers (they ride below the sight line of cars, tip on uneven pavement, don’t fit in the bike lane, etc. etc.) That means kids on our bikes. It is more challenging than the run-of-the-mill bicycle commute to school, but it’s worth it. We are often ad hoc, but we are ready to roll. Herewith, a morning’s worth of photos; an incomplete list of the ways we ride to school.

School bike #1: Bike Friday triple tandem

#1 (and by far the coolest):  Bike Friday triple tandem. Our PTA treasurer and his partner ride this bike with their daughters, who are in kindergarten and 2nd grade. They say it is the best way to commute with two kids to school in the city, and I believe them. It is easier for their dad, who is about 6’ tall, to captain, than it is for their mom, who is more like 5’4”. She reports that she needs help on the hills from the girls and she needs to concentrate while riding. The girls have to synchronize their pedaling with the parent who’s captaining; this is, I am told, not necessary on all tandems, but it is necessary on the Bike Friday [update: not exactly true; my brother-in-law wrote to tell me that any tandem could be retrofitted to have freewheel cranks that let one rider stop pedaling]. Our kids desperately want a triple tandem.

How they afforded it: They used to ride the girls to school on a tricked-out Kona Ute, which they bought and modified by hand while their youngest was still in preschool. They sold the Ute to finance the tandem, which they got for about 1/3 the list price by buying it used on eBay after searching for a used triple tandem for some time. The seller, based in LA, was unwilling to ship it, but they had a cousin in LA they visit regularly. He picked it up, and on their next visit, they took it home with them. The Bike Friday packs up in a suitcase!

How they store it: Bike storage is no joke in San Francisco. The girls’ aunt lives on the same block they do and has extra storage space, so they keep the big bikes at her place (they also have an adult tandem that they found used for free and had their bike shop fix up).

School bike #2: Surly Big Dummy

#2: Surly Big Dummy. Our friend Shirley takes her girls (1st grade and 2nd grade) to school on the deck of her Big Dummy. While they’re in school, she takes the Dummy out to do errands. I have talked about the Dummy before. It is a fun bike.

How they afforded it: They have a car that was in a horrible accident and needs several thousand dollars in repairs. Last year, they decided to skip the repairs and drive it until it failed and buy a Big Dummy (plus another bike to come) with the money they saved. When the car dies, they will be car-free.

How they store it: “It’s a problem.” They have a very small garage space with their rental apartment and squeeze the bike alongside (I presume that they don’t care about the finish of the car as it’s effectively totaled). When the car finally dies and is hauled away, however, they’ll have a very generous bike stable.

School bike #3: Giant + spare saddle on the top tube

#3: Giant with a spare saddle. One of the kindergarten dads has bolted a spare saddle to the top tube of his bike. He puts his daughter on board and takes her to school that way. When I talked with him about it, he said that although his method was totally inappropriate for long rides, their commute to school is a gradual descent over about 10 blocks and so he just coasts slowly the whole way, then drops her off, pops off the spare saddle and commutes to work.

How they afforded it: He had a spare saddle lying around anyway: this modification was free. If you had to buy one, I don’t know, $10-$20?

How they store it: No extra storage needs; it’s just a normal bike with a saddle on the top tube!

School bike #4: Kona MinUte

#4: Kona MinUte: I’ve written about our MinUte before. We ride our son to school on the back deck; we added stoker bars and some foot-pegs. This is a great bike and a flexible set-up.

How we afforded it: We bought bikes in lieu of a second car we’d been saving to buy (thank goodness).

How we store it: The MinUte isn’t much longer than a normal bike and thus has no real storage issues; Matt keeps it in a shared cubicle at his office, for example. But at home we are rich in space suitable only for bicycle storage thanks to a vituperative 50-year grudge match between the university (we live in university housing) and the local neighborhood association that prevents the partially-conditioned basement under our building, which the university was legally obligated to make ADA-accessible, from being used for a more practical purpose such as housing, or, for that matter, parking more cars.

School bike #5: Breezer Uptown 8 with Bobike Junior

#5: Breezer Uptown 8 with Bobike Junior. I haven’t written much about riding with the Bobike Junior before, as it usually makes more sense for Matt to ride our son to school on the MinUte. But with his recent injury, I’ve been handling the daily trip to school, while Matt walks our daughter to preschool then takes the N-Judah to work.

The Bobike Junior takes some getting used to, as the seat rides high, which makes the bike more tippy. It felt unstable at first. But as I’ve gotten used to it, I’ve come to love this seat. My son rides very close to me, almost as close as a backpack, and I like that when we start the ride, he hugs me from behind. It is easy to have a conversation with him because he is so close. I can turn to talk with him at stoplights and he comments on the ride, encouraging me to go faster downhill (I’m cautious; I don’t have disc brakes). It is a bit of a hassle to fit a pannier underneath this seat, and once it’s on, it encroaches a little on his foot pegs. Nonetheless, I will happily ride with my son on the Junior until he won’t tolerate it anymore.

That said, I have a suspicion that this seat might be less appealing to a shorter rider. I am 5’7.5” (to be painfully precise) and that is apparently tall enough that I can handle loads put higher on the bike without much trouble. When our friends with the triple tandem had their Kona Ute, they report that the mom had trouble handling the bike with the girls up so high on the back; she is ~3-4 inches shorter than I am. I’ve noticed that shorter people often mention they prefer to keep the load down lower, but on the other hand, there is a metronome effect. The lower loads are more stable, but if you lose control, it is a nightmare righting the bike again. The higher loads are less stable, but if you lose control, it is much less trouble righting the bike again (assuming you are tall enough). I find that I like the ease of righting the bike given that my kids bounce around a little, but some people prefer just the opposite. This is not something I’ve seen discussed much but I suspect it may be part of the reason people have strong opinions about the Xtracycle/Yuba lines (lower loads) versus the Ute and regular bikes with child seats (higher loads).

How we afforded it, how we store it: See above, blah blah, didn’t get a planned second car, it’s a normal-length bike so no atypical storage concerns, but we have tons of bicycle storage space as a side effect of a long-running town-gown battle.

These are some of the ways we ride to school. And this explains, I imagine, why our kids are begging to get a bike as obscure as a triple tandem.

Two down, two to go

Plum blossoms, first week of February

It is already feeling like spring here in San Francisco, but Matt’s torn calf muscle kind of cramped our weekend style. We had hoped to ride our bikes back to swim class across town last Saturday (this time with the short bikes, for comparison): not an option. We had thought we’d ride to our son’s school auction: didn’t happen. Instead, we got showed up by our PTA treasurer and spouse, who rode their tandem. We had ambitions of taking our son to ride in Golden Gate Park: no way, Matt can’t run alongside, and our son told me he doesn’t trust me to hold on (I think he can do more than he realizes).

Look mom, no pedals

I did take our daughter to the Music Concourse to go balance bike riding with a friend from preschool; lately, she is on fire. She rode that bike all  around the park, cheerfully covering over a mile on her own. “Let’s ride some more!” She even tried to walk it up the hill on the way home, totally impossible; her balance bike offers no mechanical advantage. Fortunately the bike is light enough that I can carry both of them.

So on Sunday we walked down to the neighborhood farmers’ market. It was probably too long a walk for Matt, really, but we were all feeling a little stir-crazy. Taking a few days off from riding, even when we go somewhere by foot or by car, has started to feel like not leaving the house at all. Sure, it’s possible, and sometimes even desirable, but go too long and you start to feel a little scuzzy.

Tastes like artichoke

But the farmers’ market was good for the kids. To their dismay, the strawberry stand is not back in operation, but we found both cardoons and pea shoots. This week had music, and we found a gang of neighborhood kids dancing together. Our daughter ran off with a friend who lives nearby, hauling her away to show off her new big-girl bed, and we all followed them home.

"Let's run away and get married!" "Okay!" (Don't let the door hit you on the way out, Prop 8.)

However Sunday was also when our son’s frustration about riding his new bike peaked. We live on a mountain, and he is not yet a confident rider. His reach exceeds his grasp, and his desire to ride is always frustrated by the terror of trying to stop on a steep downhill using his coaster brakes and a hand brake. Neither is ideal, and most days he can only remember to use one at a time, at best. As usual after a frustrating attempt at a ride and a near-fall, he returned to our building and grabbed our daughter’s balance bike (his former bike) and started riding it around the (flat) basement, which always drives her crazy and starts a fight. We are at our wits’ end.

Then last night, at a school fundraiser at Sports Basement, while all the kids were trying out ski boots for entertainment, one of our son’s classmates tripped and fell, dragging his boot over our daughter’s foot. Blood sprayed everywhere, and we sprinted to the Emergency Department for yes, the second time in two weeks. We are frequent flyers in the ED, but even for us, this was a new low. She and I were up until midnight as her doctors waited for the anesthesia to kick in and debated whether to suture. Ultimately they decided they needed to drill a hole in her toenail to drain the blood, and I lack the words to describe how awful it was to hold down my screaming daughter while listening to the whine of a drill going into her foot. As of this morning she claims she is “all better” but she’s now on restricted activity, which at this point I personally would extend to never leaving our house again.

Prior to this fiasco, I stopped by the Sports Basement bike annex and saw another of my son’s classmates with his dad, trying out a new 20” bike. “I want to get him something with gears,” his dad said. “I’m tired of towing him up the hill.” (Like many of my son’s classmates, they live on Lone Mountain.)

“Oh, do you have a tandem attachment?” I asked. I am always interested in this topic, given our son’s struggles to become a more independent rider.

“Oh no,” he said. “I just tie a rope to his bike and pull him.”

Peace out, y'all.

Although I admire the can-do spirit, I have to admit the injustice rankles. My daughter ended up in the ED after walking around a sporting goods store, while his son remains uninjured after being towed up a mountain on his bike with a rope?

Exhaustion has not made me a better person.

Bike v. bike: Yuba Mundo v4 meets the Surly Big Dummy

It's fun to say "Mundo"

Last week, while hauling around on the loaner Mundo, we met up with our friends from school who recently bought a Big Dummy. They were interested in the Mundo and we were interested in the Dummy. We all met up at Golden Gate Park on Sunday at Sunday Skate to compare the bikes.

Shirley takes her girls (1st and 2nd grade) to school every day on the deck of the Big Dummy. On weekends, her husband B.D. rides the bike and she rides on the deck, with the girls riding alongside on their own bikes. She says she gets some great videos this way, and it is an awesome sight to see them riding en masse. The ride to school with the kids on deck is mostly downhill, but she’s got to get them back home again, and they live on Lone Mountain. There is evidently some pushing, but she’s made it up many hills with her legs alone, and reports receiving applause from passing drivers for this accomplishment. I went up to Alamo Square with my two kids on the Mundo: where is my applause? Honestly, there is no justice in the universe.

Two big bikes roll into a park...

So anyway, that afternoon they rode around on the Mundo for a while and I rode a bit on the Dummy. We were in the park, so we didn’t try any hills, but it was still an interesting comparison. These bikes look similar in some ways, but they are wildly different. If I had to summarize briefly (not my strongest suit), I would say that the Mundo is like an ox, and the Dummy is like a horse. They’re both useful, but sometimes you want the carrying capacity of an ox and sometimes you want the speed of a horse.

Learning to ride the Mundo was not easy for me (not just me). It is a heavy bike that feels more like a wagon sometimes, hard to start and slow to stop, although once the momentum kicks in, riding it is mellow enough. Getting on the Dummy felt like getting on a regular bicycle that just happened to be somewhat longer than usual. I couldn’t ride the Dummy with much of a load, because Shirley and B.D. are taller than I am, and none of us are the kind of people who carry Allen wrenches everywhere we go to adjust the seat height (as if that were not obvious). The frame size was fine, but I didn’t feel comfortable putting my daughter on a bike that I had to hop down from at a stop, and for that matter, they didn’t have a child seat. So I rode it mostly unloaded. It felt fast, and it was easy to pick up and ride.

Business in front, party in back

But B.D. and Shirley could ride both bikes fully loaded, and their opinions are more informed anyway. They liked riding the Mundo, particularly the fact that it could carry three kids effortlessly. They feel that two older kids is the maximum safe load on their Dummy. Because they’re used to riding a cargo bike already, they picked up riding the Mundo much more quickly than I did. They too found the Bread Basket disconcerting at first, and almost tipped the bike figuring it out (I am not alone!) But like me, they loved the carrying capacity it added with kids on board. The kids all agreed that the Mundo was awesome, and wanted to pile on as a foursome, which we did not allow them to do. We have limits: only three kids per bicycle! For that matter, they agreed the Dummy was awesome.

Okay, next bike

Both Shirley and B.D. liked the feel of riding the Dummy better, and we all agreed it was more nimble. They also noted that the Dummy had better components, including both a lighter frame and disc brakes (optional and an extra charge on the Mundo). I concur that disc brakes should not be optional on a cargo bike in San Francisco. But, as B.D. pointed out, “The Mundo is $1,000 cheaper!” And it comes with fenders and a double-kickstand that is fearsomely stable, but hard to use: this was the only part on either bicycle that I could operate better than they could, having practiced. Neither bicycle, to everyone’s annoyance, comes with hub dynamo lights. “Why doesn’t our bike have lights?” asked Shirley. “Why doesn’t ours?” I replied. Goodness knows you’re not going to be worrying about weight or drag with either bicycle.

After riding the Mundo, we realized what the MinUte can do (it is parked)

Which bicycle would I get if money were no object? Trick question: we’d get the Kona MinUte again. We have realized lately that we’ve underestimated the MinUte; it can do far more than we’d realized. I can ride it! With both kids on board! This is a story for another day. But it’s an honest answer in some ways: I think that both bikes are designed for families that have different needs than we do.

We are a small family living in a city with extensive shopping; by preference, we get groceries several times a week in small quantities, and we carry, at most, two children. And we live on a mountain. And we are car-light, not car-free. If we were a suburban/small city family with 3 kids, particularly if they were older and we were more experienced riders: no question, the Mundo. If we were a city family like Shirley and B.D., with more serious shopping loads and a different kind of commute, we’d get the Big Dummy. If we wanted to haul furniture or heavy loads regularly, we’d get the Mundo. If we took long rides, especially off-road, we’d get the Big Dummy—B.D. took their kids on the mountain biking trails around the Palace of the Legion of Honor on the Dummy, and they all had a great time. None of us would attempt that kind of ride on the Mundo.

And of course, if money is an issue, the Mundo’s price is dramatically cheaper, even with the shouldn’t-be-optional disc brake upgrade. If money isn’t as much of a concern, the Big Dummy has more range, and it is a lot easier to ride.

I couldn’t be more pleased I got the chance to ride both bikes, and our kids were crushed when we had to pack it up at dusk (no hub dynamo lights on these bikes! curse The Man!) Riding around on cargo bikes with our kids is the best way we’ve found yet to entertain ourselves on a weekend afternoon. I would never have imagined this and it is hard to explain. Shirley and B.D. had the same difficulty that I do communicating how wonderful it feels to ride with our kids, completely different from any other mode of transportation or even any other activity. We still can’t believe it’s cheaper and easier than driving, and we keep wondering what the catch is. Like them, I am so grateful that we started this wild ride.

A long day on the Yuba Mundo

Yet another relative I talked into trying out the Mundo

A week ago Saturday we decided to ride the Mundo everywhere we went. This was maybe not the smartest move on a bike I wasn’t used to, but I figured it would be a way to learn. Also, on Saturday mornings we take the kids to swim class across town, near where my sister and brother-in-law live, which meant we could get their opinions on the Mundo, and see them for brunch. And then we figured we could pick up some groceries at Rainbow while we were in the area. Total overkill, but I’m all about overshooting my comfort zone.

We don’t ride much on the south side of the city. Once we got to the Panhandle, the entire route was flat, almost disconcertingly so. This must be the part of San Francisco where people ride fixies. On the other hand, although there are bike lanes and sharrows, the traffic down there is terrifying. It’s all giant trucks and long straight wide roads that encourage speeding and there are overpasses with freeway traffic thundering over at every turn. The whole experience of getting down there was nerve-wracking. It was a relief to reach the campus, which has a large protected quad in the center near the entrance to the pool, a bicycle and pedestrian oasis in a neighborhood that still hasn’t really transitioned away from industry.

After swim class we headed to brunch at Brickhouse, a child-friendly café with bikes hanging from the ceiling, including a push me-pull you tricycle with handles and pedals on both the front and the back (see link; as its practical value was nil, why not hang it from the ceiling?) And from there we headed to Rainbow to pick up groceries and downtown to get our mystery box from Mariquita Farms.

The Mundo I’m riding has Yuba’s new Bread Basket. This makes it possible to carry both groceries (on the front) and children (on the back). The inability of most long tail bikes to carry both kids and groceries is something that’s irritated me for quite a while. In general, if you put kids on the back, the bags can’t carry a week’s worth of groceries, because that’s where the kids’ legs need to go. I’ve found it hard to accept these bikes as being a true replacement for a car, let alone a minivan, either of which can carry both a cartload groceries and children at the same time. We don’t typically have time to split up these errands; we shop on the way home from work. I suspect our experience would be different if one of us was a stay-at-home parent, but that’s not how we roll.

It's not just me that finds it disconcerting

So the Bread Basket is a total score of an addition to the bike. However, because it is attached to the frame, and it does not move when the handlebars and wheels turn, it is deeply and profoundly disconcerting until you get used to it. I tipped the bike over twice learning to ride because the Bread Basket’s steadfast unwillingness to reflect my steering made me try to yank the handlebars too far over. I accept that it’s the right decision to put it there because its attachment to the frame means you can casually dump unbelievable weight in there, but it still freaks me out a little.

So at Rainbow, I piled about two bags of groceries in the Bread Basket, including:

  • Small bag of cumin
  • 1 bunch of green onions
  • 1 bunch of parsley
  • 2 lbs russet potatoes
  • 1 lb of cheddar cheese
  • 1 block of cream cheese
  • 1 box of Ak Mak crackers
  • 1 lb of garganelli
  • 3.5 lbs of flour
  • 1.5 lbs of raisins
  • 1 lb of couscous
  • 1 lb of rye flour
  • 1.5 lbs of dried anasazi beans
  • 1 lb of dried ayacote morado beans
  • Cupcake and chocolates for kids on the ride home

The Yuba Mundo haul

Isn’t that just fascinating? I can’t believe we’ve become such hippies; we might as well start eating dirt after a credibility-busting haul like this. Then we added a bag with our jackets (not needed for this ride), my daughter’s wet clothes after an accident at the grocery store, my U-lock, wallet, keys, etc.  The kids climbed on the back. At that point I was riding very, very slowly, but I’ll admit, I was impressed that this was possible at all.

I forgot the milk, of course. Fortunately we live near a range of bodegas open 24/7.

Matt’s Kona was pulling its weight as well; he was carrying the mystery box, which contained:

  • 1 bunch carrots
  • 1 daikon
  • 1 head savoy cabbage
  • 1 head escarole
  • 1 large bunch white turnips
  • 1 bunch red radishes
  • 1 lb peanuts
  • 1 large bag baby tat-soi
  • 2 heads cheddar cauliflower
  • 1 bag of limes
  • 2 heads couve tronchuda
  • 1 bunch formanova beets
  • 1 20# box of apples (bungeed to the deck)

The Kona MinUte haul

We had doubts about what on earth we were going to do with the couve tronchuda (answer: gyoza). I digress. On top of that, we stuffed in his jacket and U-lock and the kids’ swim gear. Don’t let anyone tell you the MinUte’s not a real cargo bike. And then we rode 4 miles home.

We were really, really tired, despite the thrill of accomplishment. As other riders commented, “You’re not even getting any help from those two.” So true, but our daughter was passed out in the Peanut at that point, so it’s just as well. The Peanut is a bear of a seat to get kids in and out of, but I like the support; 5-point restraints, full leg shields, and even some side bracing for naps. This is a much better seat in every way than the other deck-mounted seat we’ve used, the Co-Pilot Limo. (Our other rear seat, the Bobike Maxi, mounts to the frame and as a result has pros and cons relative to the Peanut.)

The Yuba is a heavy bike, even heavier with all the stuff we had on it. I found myself really resenting red lights and stop signs because I hated losing whatever momentum I’d gained and having to start from a stop.  Getting to the Panhandle path was a relief (no stopping). With a long uninterrupted route, it would have been much easier. That’s not the kind of riding we do most of the time, however. On the other hand, riding this kind of bike, loaded up as it was, meant that the entire city of San Francisco formed a cheering section on our behalf. Families walking through the park yelled, “Look at that bike!” and “That’s so cool!” and drivers kept stopping next to us, rolling down their windows, and filling me in on activities on the back of the bike (“Your daughter is sleeping in her seat!”) I find San Francisco a very friendly city in general, but on days like this it really lays on the charm.

Despite the fact that I blog, which could only be viewed as a desperate bid for attention, and haul my kids around town on my bike(s), which is attention-getting whether you want it to be or not, I have mixed feelings about all of this. I often prefer to ride quietly, solo, to work with all of the other less interesting bikes (although I miss the conversations with my kids when I do). But for a more hardcore family biking advocate, a Yuba Mundo would be a formidable weapon indeed.

San Francisco hills and grades

When we started riding our bikes, we feared San Francisco topography. We expected to need the elevator that goes up the hill to our neighborhood every day, and that was one of the reasons we avoided a real cargo bike, which was too long to fit in it. A while ago Stacy at A Simple Six asked me about our experience riding on hills, and whether we’d looked at electric assists for our bikes. I was surprised to realize, when she asked, how long it had been since we’d thought much about the hills on our regular route that much. We got stronger, and now we ride. I can’t remember the last time I took the elevator unless I was walking.

And yet. The hill where we live is no joke. If I’m carrying a kid home, I prefer to shower or at least swipe a wet washcloth even if I ride very slowly (even though my office is on a different hill, it’s not as intimidating and sweating is not an issue unless I’m somehow possessed with the idea of going fast).  I cheerfully gave up feeling guilty about not ever managing to talk myself into HIIT at the gym given that it’s required several days a week just to get home. Moreover, there are places in the city that we simply will not go.

What do I mean by hills? Here’s a sampling from around our neighborhood. Grades are drawn from veloroutes and the SFBC city map.

Hill #1: 25% grade (probably)

Hill #1: This is one of the direct routes to our home. We do not ride our bikes up this hill. We don’t drive up this hill. My students tell me they will detour three blocks to avoid walking up this hill. It is difficult to get an accurate grade, because it is bordered by the campus, and thus not surveyed by the city, but when veloroutes isn’t saying the grade is 35%+ (I find this unlikely), it claims it is 25%, which I find more plausible.

This hill has become the hideout for campus smokers (smoking is forbidden on the hospital campus) because no one else wants to go there. Taking this photograph was unpleasant as I was surrounded by secondhand smoke.

Hill #2: 17% grade

Hill #2: This is the other direct route to our home. We do not ride our bikes up this hill. We do drive up this hill when we’re in the car, and when relevant, we’ll walk up it. It is supposedly about a 17% grade. Like Hill #1, it is easy to photograph from the side because cars are not allowed to parallel park. Instead, one side of the street is nose-in 90-degree parking, and the other side is reserved for two travel lanes. This is what the City and County of San Francisco does when the streets are so steep that cars might actually roll down them while parked, even if the wheels were curbed.

Hill #3: 13% grade

Hill #3: A pretty direct route to our home. We have ridden our bikes up this hill with our kids aboard, once, in my case, with both kids aboard. That was an experience I would prefer not to repeat. This hill is estimated to run about a 13% grade, which still requires nose-in parking on one side of the street only (thus no cars in the photo) but is not so immediately off-putting to the experienced local that the thought of finding alternate routes seemed required. We walk up and down this hill several times a week and have never given it a second thought when driving. However once we learned there was a reasonably convenient detour that spread the same elevation over two blocks instead of one, we started taking that route almost exclusively. But our kids love bombing down this hill in the morning. Yeah, we’re bad parents.

Hill #4: less than 10% grade

Hill #4: On the alternate route home. This hill is less than 10% grade, and pretty typical for the streets around the city. Unless you’re in the flats of the Financial District/SoMa/China Basin (or headed there through Golden Gate Park and along the Wiggle), you’ll be going up and down a few hills like this on a typical ride in San Francisco. There are two hills like this on my way to work; one pretty short (behind the Conservatory of Flowers) and one long, extended haul up to Laurel Heights.

Cars are parallel-parked on both sides of the street; I view this as a sign that I can probably ride a potential route, even if I’m carrying one or both kids, and so far that’s been a safe assumption. That doesn’t mean the experience will be pleasant, as my efforts to drag myself up Post Street and Fulton Street have proved, pretty definitively. So far I haven’t had to get off and push, but there have been close shaves.

Hill #5: same old, same old, less than 10% grade

Hill #5: More of the same, another less than 10% grade. Again, parallel parking means that I can ride up this hill without having my heart leap out of my chest and leave me lying on the ground gasping like a fish out of water, at least on a good day. Note that all of the cars have curbed their wheels; this is the law in San Francisco, and the fine for failing to do so is so draconian that even as an occasional driver, I cannot stop myself from doing it, even it means that I spend a minute trying to figure out which direction on a flat street is closest to downhill. Matt once got a ticket for leaving his wheels straight on a flat stretch of street between two hills because he couldn’t figure out which way to turn them. He contested that ticket and won, but if you’re visiting, well, if you’re visiting you probably shouldn’t be driving in the city, you won’t enjoy it.

But if you simply can’t help yourself, good luck to you, and curb your wheels. A tremor (they’re pretty common) will shift cars a bit all over the city, which means car alarms galore, but curbed wheels mean that those parked cars won’t careen down the hill taking out a swath of other cars and pedestrians. So basically I’m pro-curbing.

Going up hills on a bike, even relatively low-key ones like these, requires some thinking if you have kids on the back. I used to regularly come close to popping wheelies as I started up the hill due to all the weight in the rear. Now I compensate by pushing down hard on the handlebars as a counterbalance as I approach; it’s only the moments when I’m distracted by something and forget that I realize that I’ve developed the habit.

Part of the reason that I am concerned about having the ability to haul our kids on the bikes for years to come, even though our son is old enough to ride, is the hills. Our kids are strong and they’ve never known any other terrain. They see us riding these hills and they accept them as normal. However I suspect it may take some time before they’re really comfortable going up several of them in a single ride on their own. I would be delighted to be proven wrong, but I think it’s safest to be prepared to bail them out.
