We tried it: Urban Arrow

As promised, the lede in 6 words:

Like Bakfietsen? You’ll love Urban Arrows.

Check it out: Redwood City has Urban Arrows and sunshine, too.

I have had a couple of recent conversations with cool bike people recently that brought up something that has been in the back of my mind for a while. My feeling is that the family biking market is still pretty nascent and as a result there are mostly two kinds of bikes out there.

On the one hand you have the macho bikes. The view of family biking by companies that make these bikes ranges from, at best, detached bemusement (e.g. Larry v. Harry, which developed some basic kid accessories like a child seat and rain cover, but has never seen any need to mention them on its website or anything), to disinterest (Kona—“oh, you can carry kids on a bike?”—and Brompton, which as a company seems unaware of the aftermarket Pere child seat), to outright hostility (e.g. Surly and its new kid-unfriendly Big Dummy deck, Trek and its no-kids-allowed Transport). But to their credit, these companies put a lot of effort into (relative) nimbleness. In the universe of cargo bikes, these bikes are lighter, have better parts, are fitted with gears that can handle hills, and are safer and easier to ride in challenging conditions, by which I mean any conditions other than a flat street on a sunny day. (Okay, I exaggerate. But still.) And these bikes can go fast. Relatively speaking.

On the other hand you have the land yachts. These bikes are definitely family-friendly. They offer awesome kid-carrying capacity (even for large families), provide multiple ways to haul stuff/other bicycles as well as kids, and often have user-friendly accessories like integrated lights, step-over frames, upright seat positions, rear wheel locks and internal hubs. On the other hand, they typically weigh a ton and have a limited gear range and weak stock brakes, making them a challenge to ride on anything but the mildest of hills. And they are slow, even in the let’s-face-it-cargo-bikes-are-tanks class. I include in this category Madsens, Bakfietsen, Yuba Mundos, and every tricycle and unassisted mamachari I have ever seen or ridden.

The cargo bike market reminds me a bit of the car market in the 1960s. You could buy a station wagon (so practical! so massive! so slow!) or you could buy a “sporty” car, and hope for the best as you stuck your kids in a homespun “car seat” or harnessed them to long straps above the rear seat that offered a non-trivial strangulation risk. My mom hauled us around in a 1965 Chevrolet Corvair for years in those harnesses, because my parents believed in buying older used cars and keeping them until they literally fell to pieces decades later.

There are exceptions, and I have ridden some. On the longtail side, Xtracycle’s EdgeRunner is both family-friendly and nimble. On the box bike side, Metrofiets customizes almost all the bikes they make, so they can be tailored to weird cargo and/or families large and small, plus they start out as more-than-decent hill climbers and can be turned into awesome ones.

And there is the Urban Arrow. Thanks to an integrated electric assist, Urban Arrow turns a bike that is completely land yacht in character into something with many of the capabilities of a macho bike.

Two big kids on a very generously-sized bench seat

The Urban Arrow is a hard bike to find, let alone to test-ride, and the only people we know who have one bought sight unseen. Fortunately for us, Motostrano in Redwood City imports them, and will allow test rides whenever it gets orders in, if you get on the wait list. Motostrano is an interesting shop. From the outside it’s all posters of scantily-clad women draped over motor scooters, which definitely gave me pause. On the inside it offers a huge selection of assisted and unassisted commuter bikes (plus other kinds of bikes that I don’t care about, FYI). And they had boxes and boxes of bike stickers that they handed over to my kids. Pasting those stickers all over their clothes and helmets completely obsessed both kids while we learned about the Urban Arrow, and made them happier than anything else they did all weekend. We were glad that we made the trip down, which was, frankly, a not-inconsiderable hassle.

What I like about the Urban Arrow

  • First, the Urban Arrow is a box bike. Not everyone loves a front-loading box bike, but I do. It’s easier to talk to the kids, it’s simple to protect them from bad weather, and the kid seating is elegant. It’s also much easier to walk front loaders than longtails because the weight is near the leverage of your arms. There is a reason that people think of—in the words of one family friend—“those bikes that look like wheelbarrows” when they think of family biking.
  • Footrest visible on the upper right, deck with drain holes, padded seat

    The Urban Arrow’s child-hauling and commuting setup is unbelievably swank. The box is made of styrofoam [update: it's not styrofoam, it's expanded polypropylene, which is evidently better--see comment below] and forms a sort of roll cage in the event that you drop the bike. The manufacturer cut out step-holes in the front to make it easy for kids to climb into the bike, and the thick styrofoam serves as an arm rest on both sides. The bench seat, which had plenty of butt-room for my 8-year-old and 5-year old, is padded (there is an optional second bench seat if you have more kids than I do). The center stand has the same rock-solid design as the best-in-class bakfiets. The bottom plate has multiple holes for drainage. It has integrated front and rear lights and the wires run through the frame so they can’t be dislodged. The chain is enclosed, so you could easily ride this bike without incident while wearing palazzo pants. For that matter you could ride it in a maxi-skirt, because it also has a step-through frame. The battery sits unobtrusively under the bench seat. It comes with fenders and an Abus rear wheel lock. It shifts seamlessly using a Nuvinci n360 internal hub. Although the Urban Arrow normally comes with roller brakes, Motostrano automatically upgrades them to disc brakes. The bike we rode did not have a rear rack, but they are available.

  • This bike looks so classy. I felt like I should have dressed up to ride it. To me, a Bakfiets, with its wooden box, looks practical, but not exactly stylish, while our Bullitt looks fast and sleek. But the Urban Arrow looks… polished, to the extent you can say that about any cargo bike.
  • Considering all the features packed into it, the Urban Arrow feels shockingly light. I expect big bikes to be heavy bikes, and realistically, it is in fact a heavy bike, tipping the scales at 99lbs/45kg. However people who ride Bakfietsen tell me their bikes as weigh about that much, and that’s without an electric assist. Both the aluminum frame and the styrofoam box are shaving a lot of heft from this bike, and with cargo bikes that’s all to the good, especially given that most people are going to throw at least twice the weight of the bike itself in the box, and then push it around.
  • The Bosch motor--note that while there's an occasional visibly wire, most of the wiring is run through the frame.

    The Bosch motor–note that while there’s an occasional visibly wire, most of the wiring is run through the frame.

    The Bosch electric assist is a fully-integrated mid-drive. It is also fully enclosed, so there are fewer worries about loose wiring, and it’s designed to work with the bike’s gearing. Mid-drive assists are powerful, although not silent. As usual with this kind of assist, I noticed a slight clanking as the chain ran through the motor, but it wasn’t offensive. The Bosch is a pedal-assist in the legal sense; turn it on and the bike just sits there, but as soon as you turn the pedals, the assist is immediately there. It won’t start without you making a (mild) effort. The controller offers three speeds, and the feeling of the assist ranges from “slight tailwind” at the lowest setting to “strong tailwind” at the highest.

  • Not everyone loves this, but it has a super-upright posture, for a great view of traffic. And it’s virtually impossible to slouch. My mom would always hassle me when I was growing up to “sit up straight!” My mom wants you to ride this bike.
  • At $5400, this is a competitively-priced assisted box bike, although I certainly would not call it cheap. An unassisted Bakfiets is now running about $3750. An assisted EdgeRunner longtail, comparably accessorized for hauling kids, would run $4700 in San Francisco. That price difference is not trivial, but it’s not outrageous either.

What I don’t like about the Urban Arrow

  • The Urban Arrow is a really big bike. Matt and I both rode it, and we realized quickly that it would not be a practical commuting bike for us in San Francisco. Matt was vehement that he would never even consider riding it on Market Street, which has a semi-random bike lane layout and many, many people competing for space in it. It would be more of a ride-in-the-park bike for us. And it is big in both dimensions—width and length. Size was a deal-killer for us when we test-rode a Metrofiets as well, and it’s a large part of the reason we’ve been hauling 2 kids (and sometimes squeezing in more) by Bullitt for almost two years—the Bullitt is narrow. If we lived in a smaller city, or a place with wider streets, or rode different kinds of routes, we’d have no problem with an Urban Arrow.
  • On a related note, turning and parking the bike is a production. It is possible to make a big bike with a (relatively) tight turning radius. This is not that kind of big bike. It is probably impossible to make a front-loading box bike that is easy to park at a standard bike rack. We bought a front loader anyway, because the advantages outweighed the disadvantages from our perspective, but it can be frustrating. However if you live in a less theft-prone municipality that we do, you could just park it without using a rack by relying solely on the rear wheel lock.
  • All front loading box bikes are tricky to learn to ride, because of the linkage steering. We don’t have many issues with that after riding ours for a couple of years, but on a new-to-us model, we’ll still always wobble off the start. It seems safe to assume that it would be worse for someone who had never ridden this kind of bike before. The Urban Arrow has one advantage in this class, however, and that is that the box blocks the view of the front wheel (watching the front wheel is bad, it will confuse you and make you dump the bike).
  • I have no idea why that controller is sitting in the middle of the handlebars. Awkward.

    I have no idea why that controller is sitting in the middle of the handlebars. Awkward.

    I found the handlebar layout very odd and somewhat frustrating. The brake levers required a big stretch to reach and pull. I have large hands and long fingers—my ability to span a ninth is part of what made me a competent pianist and organ player in my youth—and so this is nothing I have ever experienced before. These parts could be swapped for smaller ones, but given that this is a bike marketed to both women and men, and women typically have smaller hands, I found it bizarre. In addition, the controller for the assist is located in the middle of the handlebars, instead of near one hand, so to turn it on or change the level of assist, we had to take one hand off and reach over. That’s annoying and it also feels like a safety risk. Even if the controller were moved closer to one hand [see comment below; this can be done], its design is such that it would be difficult to operate by thumb.

  • This is Matt, grimacing at Dutch geometry.

    This is Matt, grimacing at Dutch geometry.

    The Urban Arrow has what those in the bike business would call Dutch geometry, which basically means that you’re riding the bike in roughly the same position that you would be in while sitting in an office chair. I am comfortable riding this kind of setup but it is not something that Matt likes, and we share all the bikes, and so we must compromise.

  • Caveat: San Francisco-specific concern. Motostrano told us that the assist would not be able to handle San Francisco’s steepest hills, even unloaded, but could not specify what kinds of grades it could climb. We had hoped to figure it out by simply riding up some hills ourselves, but unfortunately for us, Redwood City is as flat as Kansas. Furthermore, the Dutch geometry makes it impossible to bear down and crank up a hill on your own power. That’s because your chest will whack the handlebars—which is what happened when I tried to go uphill while test riding a Bakfiets. Hauling up hills on your own power is supposed to be a non-issue, because the bike has an assist, except that we were told that the assist might not be sufficient where we ride. And then it would be an issue.
  • Speaking of hills, I found the brakes slow to respond. I assumed that it was just that particular bike and suggested to Motostrano that they tighten the brakes, but they said that they’d noticed it on all of the bikes they had built. They believed that it would settle after the bike had been ridden for a while. I would love to hear confirmation of that from someone who’s actually experienced it.
  • The Urban Arrow would be almost impossible to get up to higher speeds. For quite a while this is something that I didn’t care about at all. However as time passed and we became more confident on cargo bikes, the appeal of one that can rocket along (relatively speaking) on occasion grew. It is useful when, say, the kids lock themselves in the bathroom and we end up leaving 10 minutes later than planned. The assist is not designed for speed either, but rather for steady help in the background. A BionX, in contrast, will match your effort, so you can use it to start fast and build up speed quickly. (This is fun, although BionX systems have their downsides.) Some bikes are just always going to be on the slower end—that’s just how they’re made—and the Urban Arrow is one of them. If you’re not compulsive about getting places early, this may not rank as high on your list of concerns as it does on mine.
  • Last but not least, this bike is ridiculously elusive . There are only a few shops in the country importing them, and there is a lot of unmet demand, so getting an Urban Arrow almost always involves a deposit and a wait list. We have only seen two riding around San Francisco (which is one more than anyone I know in any other city has seen—except, I presume, Portland), and at least one of those was shipped from New York. Motostrano said they were able to get all the bikes they had ordered so far in a time period between 1-3 months, which is a big improvement over the waits I heard about last year, but is still non-trivial. And if you want to do a test-ride first, count on doubling that wait because whatever bike you test-ride will be a bike that’s already been sold.
See, a foothole--there are so many nice details like that on this bike.

See, a foothole–there are so many nice details like that on this bike.

So the Urban Arrow: not the right bike for us, but definitely a cool bike. It reminded both me and Matt of the Bakfiets, but upgraded. It was like a Bakfiets that had gone on a makeover show: Harder, Better, Faster, Stronger.

I find that people tend to have a sense of what they want in a bike, even if they can’t always articulate it. There are macho bike people and land yacht people. If you are the former, this isn’t the right bike for you (and you know that already). If you are the latter—assuming that you don’t live on Twin Peaks—it’s probably the most perfect cargo bike ever made.

A series of family biking events, 2014 edition

There is a lot to do if you are interested in family biking, mostly in San Francisco but also beyond. Here’s everything I know about this summer so far in date order—and don’t miss the good stuff at the end.

July 13th (11am-4pm): Richmond Sunday Streets

We went to Richmond Sunday Streets last year—this was a great event for kids to ride their own bikes because it was car-free all the way from Golden Gate Park to Clement Street. We had no worries about cross-traffic for miles.

July 19th (11am-5pm): Fiets of Parenthood and the Disaster Relief Trials, Portland, Oregon

We are finally going to make it to Fiets of Parenthood, which will be held at the Oregon Museum of Science and Industry on July 19th. Come to compete or to test out cool cargo bikes—Splendid Cycles claims they’ll have a Bullitt with the new extra-torquey BionX D system to try. There is also a new class in the Disaster Relief Trials, the non-competitive Replenish division, as well as the competitive classes competing for time (we are so not doing that). To participate in Replenish you have to haul a non-pedaling passenger (no tandems). Our California contingent will be easy to spot, as we’ll all be on child seat-equipped Bromptons. Go Grizzlies.

August 24th (11am-4pm): Mission Sunday Streets

Our first Mission Sunday Streets in 2012

Our first Mission Sunday Streets in 2012

Mission Sunday Streets is the first we ever attended and it’s always the most crowded, but it’s no less awesome for that. We usually hightail it to Dynamo Donuts first thing in the morning, then turn around and return at a more measured pace. Our bikes are easy to spot if you’re looking for us.

September 2nd (10am-11am): How would you make buying and using a cargo bike easier? A conversation with Vie Bikes at Koret Playground in Golden Gate Park (look for the sign near the Carousel)

Vie Bikes is a new company formed by three San Francisco cargo biking parents intent on making it easy as pie to find, buy and use the best cargo bikes on the market. Among other things, Vie will offer month-to-month leasing, and built-in quarterly service that comes to you. Vie is planning to launch in San Francisco in the coming months, and expand in to new cities thereafter. Stop by Koret Playground to talk with Vie’s founders, including long-time Hum of the City reader Kit Hodge. Vie is looking for feedback from both people who have cargo bikes and people looking for them regarding key aspects of our service.If you went through the process of shopping for a cargo bike again, what would you change?If you’re in the process now, what are you finding challenging? Be part of shaping a company that will transform cargo bike use across North America. RSVP to info@viebikes.com. Can’t make it but want to weigh in? E-mail info@viebikes.com with your thoughts. We’ve known Kit for a long time and were very excited about the idea of a cargo bike leasing company, which is both totally novel and totally cool. I hear there will be sample bikes to check out as well.

September 14th (11am-4pm): Western Addition Sunday Streets

Western Addition Sunday Streets 2013

Western Addition Sunday Streets 2013

Western Addition Sunday Streets is one of my favorites because a large section of it goes through neighborhoods rather than a major commercial strip. It’s also much less crowded because the route hauls people up over Alamo Square, so beware. We usually start at Chili Pies and Ice Cream and wander over toward Japantown.

The final two events are only relevant for Rosa Parks families, but if you are such a family (or you’d like to be eventually), please feel free to join our community even before school starts.

July 12th and August 16th (11am-1pm): Rosa Parks Incoming Kindergarten class family potlucks

Family bikes round up in the lower courtyard. Incoming kindergarteners can meet and play with each other and their future teachers. These are fun events—at the August potluck, classroom assignments should be out as well. We may miss the August potluck because of our Camp Mather trip, but we’re going to try to make it to both. Hope to see you there.

Happy riding this summer.

We tried it: BionX v. Stokemonkey

Test riding the stoked EdgeRunner in Seattle. Thanks to Davey Oil for the chance to ride, and Madi Carlson for the great photo!

One of my colleagues recently taught me two great tricks. The first is to never use the word “but” when talking to people because it  always ticks them off. The second was that anything could be summed up in exactly six words. She writes six-word biographies for every graduating student in her program. It is amazing. Given that I am a chronic offender in the Too Long: Didn’t Read sweepstakes, I’ve decided to open all of my reviews with the six word summary. Here’s one now.

BionX: Easy to use

Stokemonkey: Powerful

I’m sure that the respective producers of BionX and Stokemonkey electric assists now wish that they could reach through the screen and punch me in the face. Good thing it’s a virtual world.

There are basically two heavy-hitters in the world of electric assists for cargo bikes. They are BionX, which is a rear-wheel assist (motor on the rear wheel hub), and Stokemonkey, which is a mid-drive assist (motor on the frame running through the chain). The Stokemonkey was out of production for a long time, and now it’s back. I had the chance to try both assists on the same bike, the Xtracycle EdgeRunner, while we were visiting Seattle over spring break, thanks to the lovely G&O Family Cyclery. G&O was the only shop I have ever seen that had both kinds of assists on the same model of bike, which I rode on the same hills on the same day, with both my kids on the back. It made for a near-perfect comparison. The kids ate a few crackers between the Stokemonkey ride and the BionX ride, but still.

I have already written about other brands and types of assists—there are front wheel assists, like on the original Yuba elMundo, and other companies make both rear wheel and mid-drive assists. I’m concentrating on BionX and Stokemonkey because most people shopping for an add-on family bike assist end up choosing between these two, for reasons that center around power and reliability. Both have good odds of hauling a loaded cargo bike around, and they have the reputation of being the least likely to die within a few months of purchase (or immediately after the warranty expires). People who know a lot about electric assists may end up finding or hacking something better. Nevertheless your average rider wants something that does not require the patience and ability to read through and comprehend the forums on Endless-sphere. (Note: when I refer to “pedal assist” here and everywhere else, I am using the EU legal definition, meaning an assisted bike that will only move if you are already pedaling. Although there are other definitions, this is the one that most people I speak with intuit when they hear the term pedal assist.)

BionX

We have a lot of familiarity with the BionX, because it’s the system on our Bullitt. It has served us well, although it is not perfect.

  • How much does a BionX cost? $1800 installed by The New Wheel in San Francisco (SF-suitable system with 48v battery)
  • How much does a BionX weigh? 14.1 pounds including battery

What I like about the BionX

  • The BionX is easy to use. This is a set-it-and-forget-it system combined with a throttle. You can get a boost across intersections by pushing the red button (the throttle), or set a level of assist from 1 to 4 and feel super-powered as you blaze through the city. The pedal assist is the best of any electric assist that I have tried, and I have tried a lot of them now. The BionX was the first assist that I ever tried, and in a way it spoiled me for other assists, because it is truly intuitive to use. There is no learning curve. Anyone who has ever ridden a bike can master it immediately. Many people end up leaving the bike in a relatively high gear and using the different assist levels as gears, and this actually works pretty well.
  • It is pretty powerful. BionX systems come in different flavors, and we got the most powerful, with a 48v battery. It works well in San Francisco on our daily rounds, which feature a number of serious hills (Twin Peaks, Alamo Square, Lone Mountain) and various unnamed elevation changes that would qualify as hills in a less topographically challenging city. Families in Seattle, which has less steep hills yet is nonetheless pretty hilly, seem content with the 36v battery system. The cheapest and least powerful systems are probably best for handling stiff winds in areas with mild hills.
  • It requires minimal maintenance. There are people who will argue this point. The consensus from the bike shops that we patronize is that they use their assists in a different way than we do. We rarely use the throttle; instead, we use the assist levels to maintain a steady speed and effort level. We do not burn through power trying to race other riders. We have the shop check the wiring every few months. With one major exception, which is that we initially had spokes on the rear wheel that were too thin, which broke by the dozen, the system has not given us grief. We replaced those spokes with much thicker ones and haven’t had issues since.
  • It is silent. Lots of assists make a humming noise, or much louder noises. The front wheel assists I have tried definitely sound like motors, and the EcoSpeed mid-drive frankly sounds like a motorcycle. One of the reasons we like riding bicycles is the relative quiet and the opportunity for conversations with our kids, and so the noise of some of these systems was a deal-killer for us. This is not an issue with the BionX. It is the ninja of electric assists.
  • It has regenerative braking. This means that you can use the BionX system to slow (or stop) the bike and recharge the battery while going downhill. It is debatable whether regenerative braking adds much to battery capacity—there is loss in any system. In an area like San Francisco, where steep hills abound, careful route planning can actually mean you get some power from the regenerative braking, although this may not apply outside the city. It is inarguable, however, that using the regenerative braking through the motor saves a lot of wear and tear on the bike’s brakes. And it offers me a lot of peace of mind, given that we have had brakes fail in the past. I view the BionX regenerative braking like skydivers view a backup parachute.

What I don’t like about the BionX

  • Starts can be slow and difficult. The system is set up to kick in once the bike reaches 2mph. If you are trying to start a loaded bike from a dead stop on a steep hill, you may have trouble getting to that speed. This is particularly the case if, like me, you have a bad leg. Outside of G&O, which is on a moderate hill, I could not get started with both kids on board. I had to walk to bike to a level area. This is evidently something that can be modified—you can reset the controller so that the assist kicks in at a much lower speed [update: as low as 0.5 kph]. Now that I know this, it is high on our to-do list. That modification would help a lot, yet it does not change the fact that no matter what, the initial effort on the start is going to be human-powered. This is our biggest issue with the BionX. It was less of a big deal before I was injured.
  • It gives up on really steep hills. There are hills in San Francisco that we cannot get up with a fully-loaded bike—the system overheats, which means it’s back to pure pedal-power at the worst possible time. For people outside of San Francisco, this may be no limitation whatsoever, because SF is the second-hilliest city in the world, also very windy, blah blah blah. This actually turned out not to be a huge deal for us. The system is powerful enough that it can handle most of our trips, and we prefer to take alternate routes for 18%+ grades whether we are riding assisted bikes or not. On the extremely rare occasions where there there is no alternative, there’s always transit or car-share.
  • The proprietary battery limits the range. Also it’s annoying. The BionX system is completely self-contained. It’s like Apple computers. You can’t get a battery any more powerful than the battery they supply. You can’t set up a backup battery to extend your range, except by carrying another battery and swapping it in, and their batteries are expensive. There is a big logo on it, which is irritating. However the main issue is that you have no way to control the range other than by picking one of their batteries: you get what you get. The range is not unreasonable, and it handles most of our needs, but there are times when we have to be sure to carry the charger and find a place to plug it in, or suck it up and accept that some of the trip home will be exclusively human-powered. Thankfully that is a much less painful prospect now that we no longer live on a steep hill.
  • The system can be finicky.  Matt has dropped two controllers and when you drop them, they break. In one case, the controller seemed to be fine but then the bike started jerking when the assist was on max, because it wasn’t really fine. Replacing the controller costs $100. Argh! The bike shop suggested that we super-glue the third controller in place. There is a certain amount of loose connection hassle with some of the controller parts—the wire to the regeneration system sometimes works loose, and so on. We have the wiring checked regularly and so we haven’t had those problems. I classify this in the same category as our constant brake checks. A certain amount of attention is required.

Stokemonkey

And then there is the Stokemonkey. I’ve ridden a stoked bike for exactly one day, so I can’t offer an opinion that is nearly as informed, and for obvious reasons I have no idea about maintenance.

  • How much does a Stokemonkey cost? $1250, not including the battery (varies) or installation ($125 at Clever Cycles in Portland)
  • How much does a Stokemonkey weigh? 21 pounds, not including the battery

What I like about the Stokemonkey

  • It is incredibly powerful. I would go so far as to say it is virtually unstoppable. The chain or the frame will break before the assist gives out. This is not always obvious when you are riding, because weirdly, it doesn’t feel like it is helping. However I know that the ease I was feeling while hauling 100 pounds of my children up a big hill was not natural, especially with a broken leg. If I hadn’t been sure while I was riding the stoked EdgeRunner,  it became obvious when I rode the BionX EdgeRunner, because it took a lot more effort to get up the same hill. Neither was particularly hard, but the Stokemonkey was definitely easier. I doubt there is any hill that would overpower it. Maybe a vertical wall.
  • Starting on a hill is easy. When you push the throttle, the pedals start moving and the bike starts moving. Even with warning, it was hard to be prepared for this. However I had no fear of stopping mid-hill on the Stokemonkey. It cranks right back up to full when you hit the throttle. Starts are my biggest weakness, and so this feature was, for me, the Stokemonkey’s greatest appeal. It destroys all fear of hills. No matter what the incline, it will always start.
  • It is compatible with multiple batteries. If BionX is the Apple of electric assist, Stokemonkey is the Windows environment. You can wire any battery into it, or, if you are like me, your bike shop can do it. That is a cost savings, and there is also a learning curve involved—I have no idea how to pick a battery. Any shop installing the Stokemonkey should have a good idea though.
  • It is pretty quiet. It is not totally silent like the BionX, and I don’t think that any mid-drive assist could be that quiet, because mid-drive motors run through the chain and there is some noise involved with that movement. I found it unobjectionable. There is one exception to the generally quiet nature of the Stokemonkey. If it is installed on a box bike it will be pretty loud, because the noise of the chain will echo through the box.

What I don’t like about the Stokemonkey

  • It is controlled by a throttle only. If you want the assist to kick in, you have to hold the throttle down. It did not take long for my thumb to get sore doing this. I might get used to it over time, but I doubt that I would ever stop finding it annoying.  There is not set-it-and-forget-it option with the Stokemonkey. I’ve ridden enough assisted bikes to know that this is not really workable for us. There are too many hills and too many places where we need to take our hands off the handlebars to signal.
  • It is not pedal assist, yet you must pedal. Truly, the Stokemonkey is neither fish nor fowl. When the assist comes on, the chain moves, and so the pedals also move. You have be right there ready to move your legs. Even with warning, I kept whacking my ankles on the pedals on starts because I wasn’t ready for this. On the flip side, when you release the throttle, the pedals keep moving for a little bit on their own, so again, whacked ankles. Personally I found this a small price to pay for instant starts on hills, but still: ouch. Word from people who have stoked bikes is that you get used to this and adjust relatively quickly. In the interim, wear thick socks.
  • The learning curve is not insignificant. Using a Stokemonkey was described to me as being a bit like driving a manual transmission car. Amusingly enough this analogy came by way of Davey Oil, who does not drive. Nonetheless it is pretty accurate.  The bike will start to shudder if the Stokemonkey thinks you are in the wrong gear, and then you have to shift down to make it settle. My son, sitting on the back of the bike, noticed this immediately, and he found it both fascinating and disconcerting. “You need to shift, mommy!” In combination with the pedals whacking me in the ankles, it required a lot more attentiveness to the assist while riding than I was expecting. This comes at the price of paying attention to other things, like traffic. With this system I would need to spend time getting comfortable on quiet streets without the kids on board before I would feel confident taking it out on a daily commute.
  • The Stokemonkey is only really suitable for certain bikes, mostly longtail bikes. [update: I was wrong, modifications to the original statement follow.] Stokemonkeys are not appropriate for early-model Bakfietsen with roller brakes, or presumably any bike with borderline brakes, because the bike can then get up hills that it can’t safely get down. The mounting of a Stokemonkey is evidently somewhat complicated. This seems to be the case for a lot of mid-drive assists.

The winner: everybody

That was our experience, and to my surprise, it did not feel like a definitive win for either the BionX or the Stokemonkey. I had assumed that when I tried the Stokemonkey I would feel like an idiot for getting the demonstrably less powerful BionX (not that we had a choice at the time) and that I would immediately want to swap out to a Stokemonkey. Although I was really impressed with the Stokemonkey, I didn’t feel like it was a BionX-killer. Moreover, I have no good sense of what I would want when we get a new bike, which for various reasons is on the horizon.

Both systems have strengths and weaknesses, and moreover, both systems can be tweaked/are currently being re-engineered. Grin is working on a pedal-assist, set-it-and-forget-it version of the Stokemonkey, suitable for EdgeRunners only, which [update] has just been released. This resolves my biggest issue with the Stokemonkey (and it means I could probably justify buying an EdgeRunner to myself). On the other hand, resetting the BionX controller to a lower start speed would probably resolve our issues with starts on hills, and San Francisco has a dedicated BionX shop that can handle any maintenance issues. In contrast, getting a Stokemonkey would be a long-distance operation for us. Moreover, BionX is releasing a higher-torque model suitable for super-steep SF hills this year. There isn’t an easy answer. On the other hand, there are no bad decisions to make here either.

In the meantime, I’m incredibly grateful to have had the chance to try both systems on the same bike (which is, incidentally, an awesome bike). Thanks G&O! Thanks Xtracycle!

Hills v. hills: San Francisco and Seattle

Mugging for the camera at the airport

Mugging for the camera at the airport

Last week was our spring break, and the kids and I headed north to visit my mom while Matt flew to Australia for work. This kind of thing is why I make no pretense that our car-free, zero waste schtick is carbon neutral. That said most of our travel is for business, and I believe I speak for both of us when I say that a tax on business travel that would ensure we did far less of it would be pretty awesome.

Anyway, we took the Brompton, which in circus-mode can carry both me and the kids. Flying with the Brompton was an unrelieved nightmare, due to Allegiant Airlines. They are dead to me. Their motto should be: “We will terrify your children.”

Madi demonstrates the two-kids-on-a-Brompton option.

Madi demonstrates the two-kids-on-a-Brompton option.

Nonetheless it was nice to have the bike once we got to Seattle. However I was surprised to find that despite the photos I have posted, even people who know family biking were impressed that it is possible to carry two kids on the Brompton. It’s fun, although not something I would do regularly on long rides. And I asked my son to run up the hills because I’m not the rider I used to be. And this brings me to: hills. Seattle is a hilly city, but hills in Seattle are different than hills in San Francisco.

A lot of San Francisco was built on landfill, which means that there are large chunks of the city (e.g. the Marina, the Financial District) that are perfectly flat. San Francisco doesn’t have a fixie culture because everyone is a masochist. It has a fixie culture because it’s possible to live without ever leaving the Mission. However once you want to go somewhere else, it gets tricky. The hills loom like walls, and although it’s possible to thread the needle sometimes using routes like the Wiggle, eventually people like us who go to work in offices (in Laurel Heights) and have kids in school (on the other side of Lone Mountain) have to start climbing. And San Francisco hills take no prisoners. Once we load 1-2 kids on deck, even with an assist we’re working hard. So riding in San Francisco is often: la-la-la-la-OMFG-OMFG-OMFG-wheeee!-la-la-la, etc.

Seattle is hilly in a more consistent way. In comparison to the totally-in-your-face hills of San Francisco, Seattle’s hills feel almost passive-aggressive. They meander up and down and up and down and up and down and up and down and up and down. I kept wondering where the steep hills were, because from my perspective there weren’t any. However the relentless low-key up and down is not the kind of terrain I’m used to riding and it wore me out (this has happened before—I got smoked by Madi from Family Ride on a deceptively mild-looking but seemingly endless hill in August 2012, while being fried by the equally foreign 80+F temperatures).

Bullitt-surfing is understandably more of a San Francisco thing.

Bullitt-surfing is understandably more of a San Francisco thing.

From the hill perspective, if riding in San Francisco is like occasionally ripping off a band-aid and screaming in agony, then riding in Seattle is like slowly peeling band-aids off by the dozen while feeling the adhesive tug on every single hair. Except that riding bikes is way more fun than that, of course. There’s nothing wrong with having to make an effort, it proves I’m alive and makes me stronger. I’m sure that if we lived in Seattle I would get used to Seattle hills and find them normal. Admittedly sweating on the way to work is a non-starter in my life, but this is why the universe has provided electric assists.

And speaking of assists, on this trip we stopped by the newly-opened G&O Family Cyclery, which had the Holy Grail of assist comparisons available for test rides: a Stokemonkeyed EdgeRunner and a BionX EdgeRunner. I love EdgeRunners (I-will-not-buy-another-bike-I-will-not-buy-another-bike-I-will-not-buy-another-bike) but had never tried an assisted version before. They are even better than the unassisted versions. We took the stoked and BionX EdgeRunners up and down the hills of Seattle, and if it wasn’t the same kind of challenge we face in San Francisco, it was still a fascinating experience.

My dissertation advisor had five mottos. One of them was, “Whenever you go away on a week of vacation, there’s always two weeks of work waiting for you when you come back.” Alas, this is painfully true, so coming soon: BionX v. Stokemonkey.

Even yet more San Francisco family bikes

It’s been a while since I posted about some of the bikes we see around town, which is misleading because I see more family bikes every day. Red Bullitts are so thick on the ground that I think they might have their own gang. Who knew that going with a blue Bullitt would be so passé? And I’m still trying to get a picture of the CETMA I see near our son’s school sometimes, but the dad riding that bike is just too fast for me. In the meantime, there are others.

This Surly has the motor on the front wheel, along with the clever wheel lock.

The most common family bike we see is an assisted longtail, like this one. The EdgeRunner made a big splash in SF, but there are also a lot of pre-EdgeRunner Xtracycle options running around the city. I liked this assisted Surly because I thought the front wheel lock was a clever addition. The family riding this bike parked it outside the Jewish Community Center while we were there for an event with only the wheel lock, so they didn’t need a rack. I thought that was tempting fate when I first looked at it, but realized that without the need for a rack, they could park right in front, in full view of the security guard standing at the door. The bike was still there after our 3-hour event, and I saw it parked there again a week later, so it was evidently safe enough.

This Bakfiets short belongs to our neighbor up the hill, and is well-known in the city because the owner works for the San Francisco Bicycle Coalition, which is a totally awesome organization to which we donate an increasing amount of money every year. I am grateful for their tireless efforts to create world-class bicycle infrastructure here, and that infrastructure is a big part of the reason that I get the opportunity to photograph many awesome family bikes. Thank you, SFBC! I tell all my friends to join! The Stokemonkey (now back in production!) is a recent addition, which made it possible to ride up the hills around here with kids on board. I was surprised that she reported that it is kind of noisy, given that I had heard it was silent. But if it kills the hills, it’s probably worth it.

This Cannondale tandem appeared recently at the bike rack at my office. It’s been there every morning for the last few days at least. It looks like it might be set up for two adults, or maybe an older kid. I’m surprised it has so little carrying capacity—just one rack for two people? But maybe as kids get older you end up hauling less crap around as parents. That would be something, wouldn’t it? I like big bikes (and I cannot lie) but the prospect of being able to ride a lighter bike one day… I admit, this has some appeal.

Growing up

Two kids in the standard Bullitt box, still

Two kids in the standard Bullitt box, still

We love having the Bullitt to haul our kids (and a lot of other stuff) around San Francisco, and I continue to be impressed that we can squeeze a 4-year-old and an 8-year-old into the standard front box with minimal squabbling. And with the rain canopy they never get cold or wet. Sometimes we don’t even bother to put on their shoes. However I began to wonder after a while whether riding in the box was possibly too appealing.  We got our son a geared bike for his birthday last year (a Torker Interurban, more on this bike later) when we realized that trying to get a single speed bike up the hills around our neighborhood was making him hate riding. For several months it seemed like we had waited too long. In combination with his general neophobia, he mostly ignored the new bike and asked to ride in the Bullitt instead. Our daughter loves her balance bike but was too short to get on the trailer bike or a decent pedal bike.

Ultimately I decided not to worry about it. I figured they’d want to ride more on their own eventually, probably when temperatures crept up in the spring, at which point we’d also have moved downhill. I find the riders who pull up next to us and shout “you should make them pedal!” beyond tiresome. Getting up to Parnassus Heights is no joke for strong and experienced riders, even with an assist, let alone little kids. How about I don’t tell you that you look stupid in lycra hotpants, and you don’t tell me how to get my kids up an 18% grade, mmmkay?

Weekend grocery shopping with scooter

And yet. To my surprise, over the last month, both kids have decided that they want to ride on their own. Our daughter’s legs finally got long enough that she could hop aboard the Roland and actually turn the pedals (a side effect of getting a German trailer-bike that I hadn’t considered is that Germans are crazy-tall). Our son flipped a switch in his head one day and decided to try riding his scooter to the library, and realized almost immediately that scooters are much slower than bicycles. The next day he wanted to ride his bike instead.

Heading out on the Torker Interurban

Heading out on the Torker Interurban

So now on weekends we are a family caravan. Our son rides his own bike, and our daughter rides the trailer-bike hitched onto the Bullitt. Sure, she hasn’t yet completely mastered the idea that you want to move the pedals forward while going forward, but she can give a noticeable assist when she does remember. Our son, with much encouragement, finally realized that shifting into a low gear to go up hills is neither difficult nor shameful, and he is chugging up some pretty impressive grades. Aside from some trouble with braking on steep downhills (which I completely understand because I’ve been there) he is a capable and safe rider. The front box is now available for friends or groceries or library books, or we can put one of our kids and/or the little bike in there if the ride gets too long or cold or hilly.

It's hard to see, but Matt has a 4 year old and 2 year old in the front box as well as our daughter on the trailer-bike.

I expect that there will be some backsliding into the comfort of the Bullitt box when winter digs in, but I can see the future from here. We still have some logistics to work out, because the bus that takes our son to his afterschool program does not have bike racks (yet! In the meantime I have contemplated getting him a Brompton.) Sometime next year we’ll have moved to the bottom of the hill, and the prospect of getting home after a long ride will not seem nearly as daunting to them. And once we live on a quiet and flat street, our daughter can practice riding a pedal bike near home. I worried once that we’d have to coax them into riding, but they started when they were ready.

Eventually we won’t have to carry them at all. But we’ll keep the Bullitt, of course. I love that bike, and I hear that teenage boys eat a lot of groceries.

We tried it: Ridekick cargo trailer

The Ridekick cargo trailer, unattached

The Ridekick cargo trailer (unattached) with Brompton

I was pretty impressed with the Ridekick child trailer, but it’s still a prototype so you can’t buy it yet. However I did recently get to try the Ridekick cargo trailer, which anyone can buy right now.

I originally started looking at an assisted trailer as a possible way of getting around the city when I was just back to weight-bearing and much weaker. I had hopes that the San Francisco Bicycle Coalition offered one of them as a membership benefit—they do have other trailers for members to use. But no such luck. However Ridekick was willing to drop one off and let us use it for a while, which was absolutely fabulous of them.

The appeal for me of an assisted trailer was that it was a temporary solution to my problems getting around by bike while I figured out how much strength I’d get back in the longer term. Other people, I suspect, are interested in an assisted trailer for different reasons. My sense after riding with both trailers and assisted trailers is that they are a product for people who need to haul loads sometimes. If you are riding with your kids every single day and rarely ride without them, it probably makes more sense to jump right to a cargo bike or assisted cargo bike. It is more fun to ride with the kids on the bike, in cities with a lot of traffic it feels safer to ride with the kids on the bike, and some of the logistical issues with the trailer, like the fact that it can be a pain to park, go away. But if money is tight or if there are a lot of pickup and drop-off swaps between parents, then a child trailer makes a lot of sense. And if you are hauling a bunch of tools or equipment every day then you don’t need me to tell you to consider a Bikes At Work trailer or a cargo trike or whatever.

Learning to use the Ridekick in Golden Gate Park

Learning to use the Ridekick in Golden Gate Park

If you’re looking at an (assisted) cargo trailer, maybe you have a fast and light bike but want to do major grocery shopping on the weekends, or have a long commute and want to bring a week’s worth of clean clothes on Monday and haul them back on Friday. For that kind of thing, it doesn’t necessarily make sense to add a rear rack, and a trailer will probably carry more anyway. Some people will view hauling an unassisted trailer as strength training and other people not so much. If not so much, the Ridekick cargo trailer is worth a look.

What I liked about the cargo trailer:

  • It made heavy loads disappear. One day I packed it up with over a dozen hardback library books and then bought milk and yogurt (in glass bottles) and some other groceries. Starting to pull a load like that in the trailer nearly yanked my little folding bike backwards, but a push from the assist made riding normal again. We live on a fairly substantial hill, yet I had no fears about making it home.
  • The Ridekick trailer works with any bike! I had never seriously considered putting an assist on my Brompton, as that would make it too heavy to carry, and I got a folding bike specifically for times I needed to actually take a bike places I couldn’t ride one. But putting the Ridekick trailer on the Brompton was no problem. I wish that these trailers were more available as rentals because they’re also a great way to try out riding with an assist—not being able to imagine what an assist feels like and to judge whether it is worth it seems to be a real sticking point for people who are considering one. I think that is very understandable given the price and hassle of installing electric assist on a bicycle.
  • This may be my personal issue, but riding with a cargo trailer made me feel more protected from traffic. When I started riding again I was still pretty jumpy when cars pulled up behind me, given that I had been run over from behind. Although it’s a very unlikely way to get hit on a bicycle statistically speaking, I needed time to get over my wariness. With a cargo trailer behind me I knew that it was pretty likely any car would be slowed down significantly by running over the trailer before it managed to get to me. If that had happened I would, of course, have felt pretty bad about destroying Ridekick’s trailer, but not THAT bad. (This concern in reverse, however, is one of my greatest reservations about riding with a child trailer.)
  • I have tried a throttle assist on bicycles (the Yuba elMundo) and it wasn’t my favorite, but I may not have given it enough time because the throttle assist on the Ridekick really grew on me. As a weaker rider it was really nice to feel like I could push the throttle to the max and get pulled up the hill when I needed that. The throttle itself is a push toggle and it’s quite sensitive. By pushing it lightly I could keep the assist low enough that I actually felt like my pedaling was adding something. In practice because I was trying to build strength I tended to max the assist when I was fading and catch my breath, then let it go and use the momentum the bike had gained to pedal part of the way on my own again. This got me up quite a few big hills that I couldn’t have done solo, let alone with a kid on board (I usually have a kid on board). I suspect that a lot of people could use the Ridekick this way: to build up strength. For regular use I still prefer a pedal assist but for occasional use the throttle makes a lot of sense.
  • By comparison to a decent assisted bicycle, the Ridekick cargo trailer is pretty cost-effective at $700. Yes, there are big box store style e-bikes that sell for $500 but they are junk—they have very limited range, weigh as much as boat anchors, and have batteries that will die within a few months and can’t be replaced. The Ridekick has a lot more useful life than that. It’s not useful in all the ways that an assisted bicycle would be, but for many people’s needs, an assisted bicycle would be overkill.

My reservations about the Ridekick:

  • Probably my biggest problem with the cargo trailer was that I had the chance to try the child trailer first. I liked the child trailer much better, even as a way to haul cargo. The cargo trailer is much smaller, capable of holding a couple of bags of groceries. The child trailer could haul a couple of bags of groceries AND two seven year olds, or several bags of groceries and one kid, or a giant pile of donations to Goodwill. I kept thinking of the cargo version as a single person’s trailer. It wasn’t right for the volume of stuff that I wanted to carry. I don’t think I’m the target market for this trailer.
  • All trailers, including the Ridekick, can be tricky to park. It’s actually a lot smaller than child trailers, so it wasn’t that big a deal, but at the racks at my office, for example, I had to scoot it around a little to make sure it wasn’t hanging out into the car parking places where it might get run over.
  • The battery is in the body of the trailer itself, which is fine and makes sense given that batteries are heavy, but unfortunately that means there is no way to tell how much charge is left without stopping to open the trailer. So I had a fair bit of range anxiety at the end of the day when I was riding with it. This turned out not to be justified at any point, because its range was actually pretty generous—I rack up about 10 miles up and down some major hills just going to and from work and dropping off and picking up a kid or two—and I never actually ran the battery down despite using it, especially at the beginning, pretty profligately. However I never knew how much power was left until I stopped riding, and that made me edgy. This was particularly the case because at the time my limp was so pronounced that I had a lot of trouble walking my bike up hills.
  • I did not like the attachment for the trailer. It screws on using a plate attached through the rear axle, which is pretty traditional for trailers. My sense was that it was both too easy and too hard to release. It was too easy because there after a couple of weeks the trailer fell off the bike while I was riding—in regular use, you need to tighten the screw regularly. FYI. It was too hard because if the screw was tightened appropriately, you needed tools to take it off. Given that the market for this trailer is almost certainly an occasional user, I felt like it should work like the Burley Travoy, which has a snap-in attachment that can be operated by hand. The wiring for the assist, interestingly, worked just that simply. To remove the assist wiring from the bike you only needed to pull out the plug, and to reattach it to push the plug back in. I wanted the trailer itself to attach and release that easily.
  • An issue that I suspect is more Ridekick’s problem than mine is that everyone who saw me seemed to think the trailer was homemade. People told me it was very cool and then asked me how I’d put it together, which ha ha. I suspect that the Ridekick cargo trailer would sell better if it looked a little more professional, somehow. This is the market that I’m pretty sure the Burley Travoy is targeting—the ride to work on Monday with a bunch of work clothes in the bag and return with the trailer full of dirty clothes on Friday set.  Or maybe the Ridekick just needs a bigger logo. In neon colors. I don’t know.

So the Ridekick cargo trailer: pretty cool although it’s not quite right for us (the child trailer, on the other hand, I want for traveling).

The Ridekick is the only assist I know of that you can use with a Brompton and still have the ability to lift the bike up by hand.

The Ridekick is the only assist I know of that you can use with a Brompton and still have the ability to lift the bike up by hand.

Probably the greatest thrill of riding with the Ridekick attached was being able to take my Brompton anywhere with a kid on board. Getting it up the hill where we live was simply impossible for me for most of last year, if not to this day. The commutes with the Brompton+Ridekick were some of the most memorable I’ve taken all year because I had such great conversations with my kids during those rides. On one trip home my son (almost 8 years old and still fitting on the Brompton front child seat!) relayed me the entire plot of a series of Avengers comic books, which although it did not really interest me at all, was exciting because he was so excited about it. On another trip my daughter taught me some of the Japanese songs she learned at preschool. I love carrying my kids on that seat more than any other bike seat, but the Brompton gets less use than I’d like because of the hill. With the Ridekick cargo trailer, I could carry them and all our stuff and not have to worry about any of that. “Make it go fast!” they yell when we got to a hill. And I could.
