Electric Cargo Bikes Have Car-Like Utility but Bicycle-Like Costs: Cool!

school-bus

It might seem obvious that someone who adopts a car-free lifestyle is making sacrifices in order to live by their principles. The implication is that we should pity them. Cars can go faster, farther, and carry a lot more stuff than bikes, right? So they’re better, right? Not necessarily. Urban families are finding that an electric cargo bike can be a step up—a big step up—in meeting their transportation needs. And any task they can’t do on a bike they can accomplish with a rental car or carshare car.

When we look at the amount of time we spend on driving, the distances we go, and the amount of stuff we carry in our cars most of the time, an electric cargo bike can accomplish the same tasks over half the time, but for about 1/100 the cost. Think about that. Would you pay 100 times more for Continue reading →

Permission to Bike: A Report on New York City’s New Citi-Bike Bikeshare System

Like Christmas in June!

Like Christmas in June!

New York City recently initiated an elaborate bikeshare system called Citi-Bike. It is a great gift to New Yorkers that goes beyond mere shiny bikes, practical and enjoyable as they may be. Citi-Bike’s greatest gift is that it legitimizes bicycling in a previously forbidding place: downtown Manhattan. Previous to Citi-Bike only daring, athletic and counter-cultural young men ventured onto Manhattan’s chaotic streets. But Citi-Bikes empowers people of all ages and abilities to think the formerly unthinkable: Continue reading →

Costs and Planning for a Car-Lite Family of Four

No Virtue Required: Car-Lite Family Transportation Is Less Expensive, Faster, and More Flexible than Car-Encumbered Transportation

In his recent post, my co-blogger Don writes about “the virtue in choosing the right [transportation] tool for the job”. I realized that my own family makes regular use of five, count ‘em FIVE transportation options: walking; bicycling; busing; driving various CarShare and rental vehicles; and (in dwindling amounts) driving my wife’s tiny red Mini. Yesterday epitomized our highly flexible family transportation: we criss-crossed Ithaca together and separately and then at the end of the day we all landed together on our couch like the opening sequence of a Simpson’s episode.

DIY battery box for electric Yuba Mundo

boring photo of a 36v 15Ah battery in a Granite Gear Armored Pocketboring photo of a 36v 15Ah battery in a Granite Gear Armored Pocket

I’m trying out a new battery box for our electric Yuba Mundo.

I used the weather-resistant compact file tote from OfficeMax. Inside I’ve placed our 36V 15Ah battery from Cycle9.com, which has first been padded in Granite Gear armored pocket. The padded battery fits snugly at the bottom of the box. Perfect!

The box has small handles, and I used this area to cut a small hole with a utility knife for the battery wire to come through. This placement means water would have to be going up to get into the box, so I’m expecting no rain and very little road spray could make in it there. ( Adding drain holes to the bottom could also be a good idea, just in case. )

Perils of winter biking

For the past week, Seattle has been blessed with cold, sparkling clear weather.  The crisp air makes the snow-capped mountains that surround us appear 50 miles closer.  Did I mention we live in paradise?  :-)

It’s also extra-tempting to hop on the bike and enjoy a few moments in the sun as it slinks along the horizon.  But be careful of the frost on the road!  That’s a lesson my wife just learned the hard way.

On the first workday of the new year, she was riding her bike to the bus transfer station.  As she approached a turn at the bottom of our hill, she stayed in the center of the road, well away from the frosty edges.  Unfortunately, it wasn’t apparent that even the center of the street was polished with a microscopically-thin layer of black ice.  Just enough to take down a bike, swift and hard, without a moment’s notice.

My wife landed on her hip, shoulder, and head, then slid for several yards before coming to a stop.  We’re grateful to report that she sustained only minor bruises.  That positive outcome can be attributed to three things.  First, in the middle of the car lane, she was well away from the curb and other obstacles that might have complicated the fall.  Second, the car behind her was following at a respectful distance, and she didn’t have to worry about it sliding over her.  Finally, her bike helmet prevented a nasty bump to the head and kept the pavement from scraping her face.

To helmet or not?

This incident has caused me to reexamine my opinions about bike helmet use.  Only a few weeks ago, I was taken to task by a reader for comments I had made regarding a helmetless rider on a video about electric bikes (here).  The reader referred me to a site called cyclehelmets.org, which cites various research showing that mandatory helmet laws reduce bike riding by up to 30% without reducing bicycle-related head injuries.  There are various charts like this one:

I won’t dwell on this, but the implication is that skyrocketing bike helmet use did not significantly reduce head injuries.  And the rate of bicycle injuries is similar to that of pedestrians, who remain unhelmeted in Australia at this time.

The other side of the argument (which has been going on for many years) is presented on sites like this one from the Bicycle Helmet Safety Institute.

I’m not an expert on this.  My family and I have been serious about riding bikes for only three years, and besides my wife’s recent fall, we’ve experienced only one other.  That was when I simulated a panic stop with a heavily loaded bike on wet pavement (you can read that bit of foolhardiness here if you’re curious).  Our limited experience suggests that bike helmets do more good than harm, and we’ll keep them on.

But legally requiring others to wear helmets is a more complicated issue.  Given the reduction in ridership that follows mandatory helmet laws, I’m not convinced that there is an overall increase in safety.  Having more bikes in the streets increases the safety of individual riders through better visibility, infrastructure, and driver familiarity.

I realize that this is a contradiction relative to my opinions about mandatory seat belt laws.  Those laws have led to documented reductions in highway deaths.  That’s good for individuals and society.  On the other hand, helmet laws may save a few individual bonks on the head, but may reduce benefits to society as a whole and bike riders in particular.  Until there is a pretty strong case otherwise, I think our default stance should be individual responsibility.

Slippery Seattle

The other lesson for my family is that we should stay off bikes when the temperature dips below 37 degrees Fahrenheit.  I realize that people all over the world ride bikes in temperatures colder than that (we routinely did so in Copenhagen), but Seattle has some special considerations.  Our hills, our minimal bike lanes, and the mixture of car and bike traffic are part of the difference. 

But perhaps the biggest factor is salt.

When it snows in Copenhagen, the bike lanes are plowed even before the streets are (that always amazed us).  And then the lanes are liberally seasoned with salt.

This has two results: we never slipped during our winter in Copenhagen (admittedly, the 2007-2008 winter was an unusually mild one there), and my bike displayed an appalling amount of rust after only one season.  In Seattle, car dealers often make a big deal about used cars that are “local”.  You don’t want some rusty hunk of junk from some other state that uses salt, they say.

But there’s a very good reason why Seattle doesn’t salt its streets and probably never will: salmon.  Adding salt to the already oily brew that washes off our roadways could deliver a potentially lethal shock to young salmon.  One might wonder if it’s appropriate to endanger human lives on slick roads for the welfare of fish.

Well, if you haven’t lived in the Pacific Northwest, it might be difficult to appreciate the importance of salmon.  Fresh salmon are not just an important food (featured in almost every menu of local restaurants), they are integral to our economy, our culture, and our environment.  Children study salmon in school, and we celebrate them with community festivals in the fall.  The incredible migration upstream to spawn is a metaphor for dedication to a goal in the face of overwhelming obstacles.  In the process, salmon deliver literally millions of tons of nutrients from the ocean to our rain forests, enabling a rich ecology that couldn’t exist otherwise.

You would think our love for salmon and a generally eco-conscious mindset among Seattle residents would spur us to develop alternatives to car-based transportation.  But instead we have endless arguments and litigation.  We disagree on the placement of light-rail lines, expansion and tolling of our bridges, replacement of the earthquake-damaged highway which is a blight on the city, and how to fund buses and ferries.  There are squabbles between residents, transportation agencies, the legislature, and city councils.

I think of this as a testament to the tenacity of our car culture.  It has taken over a century to develop our current transportation strategy, and it may take the better part of a century to unwind it.  I’m hoping that in ten or twenty years, we will see a visible reduction in the steady stream of cars that crosses a bridge we see from our house.

Change at that pace is likely to be appreciated only by the truly patient.

The sweat threshold is the level of physical activity above which you begin to
sweat. Bike commuters ride below the sweat threshold– sometimes just below it– to arrive at the destination presentable and without using special clothing for cycling.

Missed the Bus

Missed the bus
J. missed the bus to high school today, and I was tasked with getting the girls to school and daycare on time.

With temperatures in the upper 20s, we piled on to the electric-assisted Yuba Mundo and headed out. For this trip we dressed the toddler more aggressively to block the wind generated from the bike’s speed. Her commuting clothes included a winter helmet with built-in ear covers, a balaclava, mittens over gloves, snow pants and a winter coat. She reported that nothing was cold when we arrived at daycare about 15 minutes later.

Winter bike commuting with child

winter bike commuting mom
My wife and daughter have been starting to winter bike commute this season.

One of the clothing challenges is the conflict between wearing a helmet for safety and wearing a winter hat for warmth, realizing that very few winter hats are designed to go under or over a helmet.

For the baby, I decided to try a kids winter helmet, which has few air vents includes padded ear covers. It’s paired here with a “thick and thin” kids balaclava that is thin on top and fleece on the bottom. Initially, this seems like it’s going to be a good solution.

For the baby’s hands we’ve been trying fleece mittens, but they have proven not to be warm enough, even for a for 10 to 15 minute trip, so we’ll look for something warmer. Likewise, the fleece blanket pulled over standard-weight pants didn’t work great either. We’ll be looking to refine that as well.

My wife was generally able to stay warm. She added a Turtle Fur headband to keep her ears warm, as well as a fleece neck gaiter and “windstopper” gloves.
Overall I think the experience was positive and something we’ll continue to try.

Electric cargo bikes everywhere

About five months ago, I wrote an article called Dawn of the (U.S.) cargo bike revolution.  At the time, the title seemed like a pretty big leap.  I was extrapolating a new market and mode of transportation based on two barely-available cargo bikes with electric motor options.

If I was worried I was out on a limb last May, in retrospect I was just uncovering the tip of the iceberg.  In the past few weeks, I’ve been overwhelmed by numerous electric cargo bike designs.  I wish I could cover all of them in as much detail as my recent review of the Urban Arrow, but it takes a lot of time and energy to write reviews like that, and this is not a full-time job for me.  :-)

Onya Cycles

Onya Cycles is a San Francisco-based company with three different electric cargo bikes in the works.  They are the brainchildren of inventor Saul Griffith, who won the MacArthur “Genius” award for a variety of projects he has initiated.  Saul owned several cargo bikes and wanted to try his hand at correcting deficiencies he saw in each.  His innovations range from the somewhat incremental to the fairly radical – definitely worth a mention here.

Onya’s bikes could fit under my “third generation” criteria (bikes designed with electric assistance as a central feature), but in contrast to the Urban Arrow, they will be available without the motor for people with flatter commutes or Lance Armstrong legs.  The current BMC motor/battery option is the same for all three bikes and adds around $1300 to the price of each.  The motor is rated at 600W (2000W peak) – these people have to face some of the steepest urban hills in the country, and they are serious about them!  The battery provides 10 amp-hours at 48V - enough to provide assistance for about 20 miles.  Onya bikes ride on 20″ wheels to increase torque and lower the center of gravity.  They also have 160mm disc brakes on every wheel (did I mention these guys think about hills?)

Onya Mule

Onya’s “Mule” cycle won’t surprise regular readers of my blog.  Like most of the bikes I’ve reviewed during the past year, it’s a longtail.  However, it is the first assisted longtail available prebuilt from a manufacturer that adheres to the Xtracycle standard, which opens the door for Xtracycle-compatible accessories (rather than locking into accessories provided by the bike’s manufacturer).  There are arguments on both sides whether Xtracycle standardization is a good thing, but it makes a lot of sense for a smaller company like Onya to leverage the standard.  The target price of around $3000 (powered) is high compared to the competition, but if you’ve got hills, the heavy-duty brakes and motor might justify the premium price.

Onya E.T.

The “E.T.” cargo bike is an interesting new shape (at least, new for the U.S.) for transporting lighter loads (less than 50 pounds) with a more compact bike.  With a normal-length wheel base, this might fit on standard bike racks if the front bucket doesn’t get in the way.  Target release for both the Mule and the E.T. is early in 2012.

Onya Front End Loader

I saved the most interesting for last.  The “Front End Loader” is the first serious electric tricycle that I know of.  Besides the hill-hungry motor and three disc brakes, the suspension is very interesting.  It allows you to lean the bike during turns, reducing the risk of lifting a wheel (or worse).  The company is quite proud of the custom computer code they had to write to model and optimize the tilting mechanism.  You can meet the inventor and watch the bike climbing hills and tilting through turns in this video:

Leaning Loader

If you want to see lots of hills and turns, here’s another video with pretty much nothing but that.

The Front End Loader is closer to release than the other two bikes.  Onya has already sold 10 beta test Loaders for $4200 each.  They realize that price is high, and hope to reduce it as they increase production volume.

The videos show the bike climbing significant hills with little or no pedaling.  I watched that with a mixture of excitement, dread, and even a bit of skepticism.  I’m excited because this was almost exactly my wish when I daydreamed about a perfect bike for my friends and neighbors last May.  I asserted that people of all ages and abilities needed to be able to ride up a hill at a decent pace in order to make cargo bikes practical for a broad audience.  Maybe that day is close at hand.  A tricycle addresses concerns about balance at low speeds. However, I’m concerned that first-time bikers may hop on bikes with this kind of power and exceed their skill levels.  A few unfortunate accidents could give the nascent market a black eye, and it might even produce legislation that could curtail the use of these bikes.  I’ll have more to say on that later.

Finally, I’m a little skeptical because riding a bike up a hill at the claimed speed requires enormous amounts of power.  I have questions about the battery’s ability to sustain that, and the motor’s ability to handle the heat that is generated.  I’m hoping these are issues that a MacArthur genius can solve.

Regardless of how these bikes turn out, Onya Cycles is interesting in another respect.  Like Urban Arrow, this is a company whose sole products are cargo bikes (and primarily electric).  These companies represent a bold bet that the electric cargo biking market is here to stay.  Unlike Trek and Kona, they don’t have traditional bikes to fall back on if interest in cargo biking stumbles.

I am further encouraged that these companies are not making a bunch of “me too” products.  At this point, each of the bikes I’ve mentioned in this blog might address a fairly small niche.  But taken together, they cover a pretty broad range of riders and uses.  We’re not growing a mono-culture crop here.  Just as biodiversity indicates a healthy ecosystem, a variety of cargo biking designs bodes well for the health of this kind of transportation.

Once again, I’m looking at developments I didn’t expect to see so soon.  However, I know what cargo biking will look like when it enters the mainstream, and I bet you do, too.  We’ll see stores like Wal-mart and Costco selling electric cargo bikes for about half the price of today’s models.  They will be made in China, and probably designed there as well.  When that day comes, I won’t know whether to cheer or cry…

Advanced Vehicle Design

Speaking of different designs, a German company (formerly British) named Advanced Vehicle Design produces quadricycles for business with a couple of motor choices.  Another first: electric-assisted recumbents!  While these might be expensive for individuals, they provide an impressive way for businesses to burnish their eco-friendly credentials.  And they look cool:

AVD Truck

AVD Van

AVD Taxi

But where can you drive them?  I’ve been trying to figure out how they fit into the vehicle code of my state.  There are regulations pertaining to medium-speed electric vehicles (speed limited to 45 mph), and there are rules for electric bicycles.  But I’m left scratching my head: where could I legally drive a quadricycle?  In the bike lane?  Probably won’t fit.  On the road with car traffic?  That would be an annoying obstacle for drivers on some of our faster roads, even with electric assistance.  Perhaps these vehicles are really only useful in big cities, although there are plenty of opportunities there.

Legal infrastructure

After our year of living in Copenhagen, it’s easy to see how far the physical infrastructure in most American cities needs to evolve to support lower-speed and lower-energy transportation choices.  The legal infrastructure pertaining to electric bikes also needs to evolve – that became increasingly clear as I perused the Washington State Vehicle Code.  Different statutes from state to state and country to country impede progress.  On the other hand, I fear that regulations developed in the absence of a real understanding of these vehicles will go overboard and unreasonably restrict them.

For example, I have a friend who does a good job of tracking biking trails on his blog and trail network website.  He alerted me to a recent ruling that restricts use of electric bikes on a trail near Aspen, Colorado.  The bewildering varieties and capabilities of different bikes and motors stumped officials until they made it easy: no electric assistance allowed, period.  Although that regulation may be revisited, similar motions will be considered in many town councils and state legislatures.  To maintain our freedom of mobility, we need to play a part in these discussions.

The situation that concerns me most is transport of children.  That is a uniquely emotional issue that biking critics will use to restrict cargo bikes on the grounds of safety.  If I weren’t allowed to transport my kids by bike, at least half my bike trips would be eliminated, and it would then be difficult to justify the cost of my “car replacement bike.”  Cargo bikes will eventually reach a critical mass, and there will be a significant outcry if their use is unreasonably curtailed.  But at this point, I feel the industry is vulnerable to restrictions that might appear as reasonable compromises to non-bikers.

To avoid any sort of legal backlash, I believe we need to help the public understand the benefits and the realities of cargo biking.  Sometimes advocates of a greener life style get a little too enthusiastic and the public gets over-hyped impressions of cargo bikes.  For example, in the following video, a helmetless rider carries two kids (at least they have helmets) on a bike that the motor propels at “up to 30 mph” (well over the federal legal limit).  Can you blame people for becoming alarmed when they see that?

Although I may be alone in this, I also think cargo biking will receive long-term benefits if we are careful to follow traffic laws – even the ones that don’t seem to take electric cargo bikes into account (read BikeForth.org’s counterargument here).  If we flaunt the laws we don’t like and annoy 99.9% of the people with whom we share the road, we will have few friends to defend us when laws begin to restrict what/where/how we ride.  I realize this advice goes against a cargo biker’s natural inclinations towards non-conformity, but if I can help my community embrace a slower-speed, greener, more sociable lifestyle, living within the rules is a small price to pay.

Third generation electric cargo bike

I worked in the computer industry for three decades, so I am accustomed to the furious pace of innovation associated with that enterprise.  Even so, I have been surprised by the pace of development of electric bikes in general.  While competition in the electric cargo bike category has been a little less fierce, it’s amazing that we’ve witnessed three generations of development in a little over a year.

The first generation of electric cargo bikes were do-it-yourself jobs.  Customers had to pick a bike and a motor, put them together, and hope the marriage would be a good one.  That’s what I did with my Rans Hammer Truck and BionX motor, and as you probably know, I’m pleased with the result.  But there are quirks and compromises that I have to warn people about when they take my bike for a test drive.  There are issues (like a non-existant gear) that wouldn’t be tolerable on a bike that was manufactured with an integrated motor.

I’ve written extensively about the second generation of electric cargo bikes.  These are cargo bikes that come with an optional motor from the manufacturer, like the Kona Electric Ute, Yuba elMundo, and Trek Transport+.  Each of these bikes is available in assisted or non-assisted versions.  The motorized versions reduce the guesswork and installation labor compared to the preceding generation.

I’ve frequently mused what a third-generation electric cargo bike would look like.  What if a manufacturer, instead of adding a motor to a non-assisted bike, decided to start from scratch and design a bike that integrated electric assistance so fundamentally that it defined the essence of the bike?

Several days ago, I got my first answer to this question from a Dutch company named Urban Arrow.

Urban Arrow

Let me just say it: I’m very excited about this bike.  Just in case my exuberance gets ahead of my experience, I’d like to be clear why I’m excited about it.  It’s not just about what the bike is, but what it represents: a preview of where I expected electric cargo bikes to be in another couple of years.  If the company manages to sell this bike next year at their current price target, the market is maturing faster than I imagined.  Either that or they are a little ahead of where the market opportunity is today.  It will be fascinating to find out.

I will caveat my remarks by acknowledging that I’ve never ridden this bike or seen it in person.  Since Seattle is pretty far from Amsterdam, I don’t know when I’ll have that pleasure.  However, the Urban Arrow won an Innovation Award last month at the Eurobike Show in Friedrichshafen, Germany.  So at least I’m not alone in my appreciation.

Without further ado, here it is:

Urban Arrow

Yes, it’s a front loader – the first with integrated electric assistance that I’m aware of.  As I’ve said before, front loaders are common in Europe, but they look pretty strange to North Americans who may have never seen one in person.  Despite the unusual configuration, a front loader is really what you want if you’re transporting young children.  With a lower center of gravity, their wiggles won’t disturb the equilibrium of the bike as much.  In a worst-case scenario, they won’t have as far to fall.  It’s also comforting to have them strapped in a sturdy box and under their parents’ watchful eye.  Furthermore, when the weather turns wet, you can do this:

Urban Arrow with cargo cover

I can’t imagine a kid who wouldn’t be thrilled to ride in that cozy compartment.  There really isn’t a comparable way to shelter your kids on a longtail bike.  The cargo box features a bench seat (which hides the removable battery), 2.5″-thick high density foam for comfort and safety, a grocery net, and even cup holders!  The box can be removed to convert into a flat-bed cargo bike, although I’m not sure how simple that is to do.

Groceries and passenger in the box

Most front loader bikes are heavy – between 70 and 100 pounds, and that’s without a motor or battery.  The Urban Arrow uses an aluminum frame to keep the weight under 100 pounds including the motor and battery.  That’s not exactly light compared to the longtails I’ve reviewed, but it’s prepared to handle some serious cargo.  The company claims it can carry up to 400 pounds in addition to the rider.  As usual, I wouldn’t want to test those limits, especially coming downhill.

Although the company doesn’t refer to the angled seat stem and forward pedals as a “crankforward” design, it’s closer to the posture of my Hammer Truck than the other bikes I’ve reviewed.  I’ve described the advantages of this design in previous articles, but perhaps the main advantage is reduced step-down height.  You can get your foot on the ground while seated without tipping the bike and your cargo too far.

Motor and transmission

Daum crank motor and chain

The Urban Arrow is assisted by a 250-watt motor manufactured by the German company Daum.  In previous articles, I’ve faulted the Electric Ute for using a 250W motor, which I felt was inadequate for carrying cargo uphill.  But even though the power rating is the same, there’s a critical difference between these bikes: the Ute has a hub motor, which typically produces less torque at lower hill-climbing speeds.  The Arrow’s motor is connected to the crank, and it drives the wheel through the transmission – just like your legs.  If the motor is beginning to fade at low speed, you can simply shift to a lower gear to increase cranking speed and get closer to the motor’s optimum torque range.

Stoke Monkey motor

This idea isn’t new.  Cargo bikers have been using Stoke Monkey motors to drive their cranks for years.  But the Stoke Monkey requires an extra chain to drive the crank, and another extra-long chain to drive the rear wheel of a longtail bike.  If you’re the type that likes to lubricate and adjust chains in your spare time, a Stoke Monkey might work for you, but it’s not a solution that is likely to appeal to the mass market.

The Urban Arrow’s design avoids another pitfall of the Stoke Monkey: shifting under power.  If you’ve opened up the throttle on your Stoke Monkey and then try to shift, you have at least 2 times the strength of your legs ready to grind through your derailleur and gears.  The Arrow uses a Shimano Nexus 8 transmission to dispense with the gears and derailleur.  Besides easier and more reliable shifting, the Shimano hub allows you to shift even when you are stopped or under load.  That makes shifting one less thing to worry about.

Urban Arrow in urban setting

Eight gears seems adequate with motor assistance.  I have 21 gears on my bike, but I only use the top 3 or 4 of them when the motor is helping.  However, if you want to carry cargo over hills beyond the bike’s battery range, eight gears might not be enough.  The company claims an assisted range of over 30 miles, but I suspect those are relatively flat miles in Holland, not Seattle hills.  Battery capacity is 36V at 9.5 amp-hours.

Like almost all the electric cargo bikes I’ve reviewed in previous blog posts (with the exception of the Yuba elMundo), motor effort is controlled through a torque sensor which measures how hard you are pressing on the pedals, and then kicks in a proportional amount of assistance.  I prefer this method to a manual throttle.  Twisting both a throttle and a gear shifter is more than I care to think about when I’m negotiating traffic and road hazards.

To comply with European law, the motor is only allowed to assist up to 15 mph.  In my opinion, that is a bit conservative, but probably wise.  Especially when people are carrying kids, we shouldn’t encourage them to exceed that speed.

The drive chain of the Urban Arrow is nicely enclosed to keep it away from clothing and small fingers.  It’s a great feature enabled by the internal hub transmission.  I would still like to ride a chain-less bike someday, but this is a nice step in the right direction.

Daum display

Assistance level and a wealth of other information is displayed on the large Daum control panel.  Apparently, it will even measure your heart rate if you’re riding for fitness.  A premium version includes GPS (for a premium price).  That could be useful for rental bikes, letting the rider know where they are, and helping the rental company to keep track of their bikes.  If a bike is stolen, the GPS unit can tell you where it is via SMS messages.

Brakes

Shimano roller brake

When I saw the first photos of the Urban Arrow, I was excited to see disc brakes on the front and rear wheels.  A company representative soon corrected my false impression: the disc-like features on the axles are actually cooling fins for Shimano roller brakes.  The company deliberately chose roller brakes rather than disc brakes to reduce the possibility of skidding.  Having experienced the dangers of skidding with a heavy load, that sounds good to me.  On the other hand, will these brakes handle the long, steep incline that heats my disc rotors to the point of scorching?  I don’t think Holland has hills like that, so the performance of these brakes on steeper terrain is still a concern for me.

When you look closely at the front wheel, you see something next to the roller brake fin.  At first I thought it was a hub motor: it’s nearly the same size as the Ute’s motor.  But it’s actually a hub dynamo.  It produces electricity as it spins.  At first that seemed odd to me – you’re spending electricity on the back wheel to produce electricity on the front wheel.  Fortunately, my contact at the company cleared up the mystery.  They need the hub dynamo to determine how fast the bike is going so they can keep electric assistance within legal limits. 

Lights

Excess electricity from the dynamo will be used to power the Arrow’s front and rear running lights.  For increased safety, I’d be willing to accept a little drag on the front wheel even during daylight hours.  I’m not sure what happens at night before you achieve sufficient speed to fully power the lights.  I would be tempted to put Down Low Glow light tubes on either side of the cargo box to enhance visibility from the side in the evening.

Videos

The videos and slideshow below require Flash and won’t be visible if you’re reading this article through my email feed.  If you would like to see them, click here to open the article in your browser.

The video below shows the Urban Arrow carrying kids.  It’s in Dutch with English subtitles.

The next video is a review of the bike by a Dutch technology reporter.  Unfortunately, it’s all in Dutch with no translation.  I included it here because it contains two interesting clips.  In the first, the rider performs a U-turn with the bike.  That’s one drawback of the front-loader design; the rod that turns the front wheel prevents sharp turns, so a short-radius U-turn requires some back-and-forth.  The second clip compares hill climbing with and without motor assistance (he thinks that is a hill?!? :-) )  I couldn’t hear any difference between the two, raising my hopes that the motor is as quiet as the company claims.

Price and availability

The company is aiming to start selling the bike in the U.S. in the second quarter of 2011 for around $3700.  That’s at least $1000 more than the motorized longtails I’ve been reviewing, so that alone might narrow the market for this bike.  On the other hand, it’s in the ballpark of similar front-loaders without a motor (like this Bullitt from Splendid Cycles).  If you’re looking for a kid carrier, the Urban Arrow would be a good deal at that price.  The rain cover will add about $250.

Price is just one factor that will determine the success of the Urban Arrow in the U.S.  I’ve already wondered how this bike will perform on steeper hills, but there are plenty of places in the U.S. where the landscape is more forgiving.

I think the bigger question will be dealer support.  If I were going to invest thousands of dollars in a bike like this, I would want a reliable and knowledgeable bike shop nearby who could maintain and repair the bike, when necessary.  I’m guessing that few bike shops in this country would be familiar with Daum motors, and although Shimano is a well-known name, experience with roller brakes may also be sparse.

I’m hoping that some American bike shops will start selling the Urban Arrow and specializing in its upkeep.  A really savvy shop could alleviate customer concerns by offering free pickup of a disabled bike.  Even if the bike is your “second car”, getting its 8-foot length into or onto your first car could be a challenge.  By way of comparison, loading my 7-foot Hammer Truck into our mini-van is pretty tight, even with the back seats removed.

Final thoughts

It’s ironic that a bike I’ve never seen has inspired me to write a longer review than one I’ve actually seen and ridden (like the Electric Ute).  I’ve never felt comfortable writing about a bike that I’ve only met in cyberspace, but I’ve done it before when I felt it gave a better idea of the range of options and where the market is headed.  That reasoning justifies this article because the Urban Arrow breaks new ground in several ways.  It’s a harbinger of a new generation of bikes, and I’m excited about that possibility.  I hope other third-generation bikes are around the corner rather than years away.  If I get a clue, I’ll be happy to let you know.

The Urban Arrow is enough of a leap forward, I can’t stop myself from wondering what a fourth-generation bike would be like.  In my opinion, the next major advance will be some sort of automatic transmission.  As I’ve mentioned in a previous article, truly practical human-assisted transport will isolate rider effort from the terrain.  Someday, a rider will pedal at a steady, comfortable pace, regardless of whether they are going uphill or down, and biking infrastructure in our cities will become more accomodating as riders of all ages and fitness levels discover they can participate in this revolution. 

If nothing else, the Urban Arrow gives me hope that this vision is still achievable and on track.
