It's a "Bike" only because it has two wheels...

Here's the "Yikebike", a Kiwi-designed transportation device that is going to get a lot of press as the successor to the Segway. In some ways, it's a worthy successor. Here's the remarkably well-produced marketing movie, replete with Europop-music, neon-green contrail, and catchy phrases.

The Yikebike is a foldable, baggable, portable, minimalistic electric transportation system. It's not an "E-bike", at least insofar as there is no way to pedal the thing when the battery runs out. It's not high-performance, as most average-to-good urban cyclists could whip it soundly over a short course of a couple of city blocks.

The "YikeBike" has been getting more coverage on gadget blogs than on cycling blogs, and this is for good reason. (It's not, after all, a bicycle as we think of it.) Here are some pertinent specs:
  • Range: 9-10 kms (5.5-6.3 miles);
  • Payload: 100 kg (220 lbs.) including baggage;
  • Charging time: 20 mins for 80% charge;
  • Charging cost: $0.15-0.20;
  • Vehicle weight: 10 kg;
  • Cost: Between $5200 and $5900.
There's a lot to like about the YikeBike concept, especially its product design. The folding design is top-notch, really well thought-out, and clever to boot (I love the "penny-farthing" iconography combined with the "Keep-on-Truckin" posture of the rider). The unit, when folded, appears to be actually compact enough to sling over a shoulder in its special bag. The steering system is compact, innovative, and (at low speeds at least appears to be) effective. The marketing (so far) is quite catchy. But as a serious alternative to bicycles (and let's be fair, it does present itself as such an alternative in its movie), it fails. The range is too short as an alternative to cycling (my daily commute is twice the YikeBike's range each way), and certainly too short as an alternative to car-commuting (which it also tries to undertake).

This raises the problematic question: if the YikeBike isn't a serious alternative to cycling or aut0-commuting, what is it an alternative to? The uncomfortable answer: walking. Walking on a very short commute, or walking to and from the bus-stop. Not even an e-bike purports to replace walking, typically they replace hill-climbing. (And that's fair enough, I suppose.) E-bikers will actually pedal on the flats, extending their range indefinitely, although too bad for them on the climbs when the juice runs out.

I say we need more walking, not less, and therefore I predict the YikeBike will join the Segway in the pantheon of vehicles for sore-footed tourists who want to do extended-range walking tours in urban settings. There are a lot of good design ideas there, though.

Postscript: what do I really, really, really like about the YikeBike movie? Check it out. The uber-cool YikeBiker is wearing Chuck Taylor All-Star Black Monos. This is the ultimate shoe in the world. It can be worn anywhere: your local skateboarding park, a cocktail party, with a tux to an opening at the Kennedy Center. It's green, recyclable, and your yoga teacher will like it, because it folds and gives your feet an opportunity to learn how to Walk Right. I own two pair (one high-top and one low) and am happy to bestow on them the Practical Cyclists' Seal of Approval. (Now if Converse only made them SPD compatible!)

P.U.M.A.

This is too ironic. Here's a verbatim quote from the GM introduction of the "P.U.M.A." auto-balancing two person vehicle made in joint venture with Segway:

"Imagine moving about cities in a vehicle fashioned to your taste, that's fun to drive and ride in, that safely takes you where you want to go, and "connects" you to friends and family, while using clean, renewable energy, producing zero vehicle tailpipe emissions, and without the stress of traffic jams," said Burns. "And imagine doing this for one-fourth to one-third the cost of what you pay to own and operate today's automobile. This is what Project P.U.M.A. (Personal Urban Mobility and Accessibility) is capable of delivering."

Yes. Imagine that. Let's imagine this as a series of bullet points, shall we?
A vehicle:
• tailored to your tastes
• fun to drive and ride
• safely takes you where you want to go
• "connects" you to friends and family
• using clean, renewable energy
• producing zero vehicle tailpipe emissions
• without the stress of traffic jams

I say that my commute (which is to say, my bike) can robustly answer "check!" to all of these with the possible exception of the "connects you to friends and family" item which seems to me to be more like a cell phone than a vehicle. But my bike, maybe kinda sorta, can be said to do even this.

This whole thing beggars the imagination. I've accused GM of incompetence before (before this abomination, even well before the first bailout).

But the point is, really: What does the fact that PUMA can be taken seriously say about us as a society, anyway? Are we so culturally averse to physical activity (and to sweat) that we'll do anything to avoid it, as beneath us? The Roman poet Juvenal described the ideal of the "healthy mind in the healthy body"; the apostle Paul referred to the "body as a temple". It does seem that there is something particularly American about this; you don't see this aversion to activity in Europe. Can this be laid at the feet of Madison Avenue, who basically elevated BO (and therefore sweat) to the level of a mortal sin?

And, does that guy in the photo above have any notion of just how truly dorky he looks? I mean, didn't everyone see Wall-E?


Have we really, truly become South Park? (Thanks to Geeks are Sexy for the reference.) Man, I would feel so much better if I knew this were GM perpetrating an elaborate joke. But I don't think so; they're a week late.

The Day the Earth Stood Still

In anticipation (dread?) of the upcoming Keanu Reeves movie, I got on Netflix and watched the original 1951 Michael Rennie TDTESS tonight (it can be streamed, along with a lot of other sci-fi classics). Although the special effects were weak (the flying saucer never changed perspective in any of the shots, which means it was probably a hand-painted cel), the sets were great (especially the saucer interior), and the Theremin music was probably state of the art for the time.

You all know the premise, so I won't rework it here. But in none of the shots of traffic tie-ups anywhere across the world was there even one bicycle! I guess it would have given the lie to, uh, "standing still". Hey, bicyclists don't need no stinkin' electricity, at least as long as it's daytime.

The trailers for the new TDTESS look a lot more destructive. And I'm getting the idea (wonder where from) that the new movie has a more "green" and less "anti-nuke" theme to it. So I'm betting that when things drag to a halt in the new movie, we in fact DO see cyclists moving around. Anybody want some action on this??

Bike-onomics, or, What Succeeds the Bike?

Here's a link to an article in the Week in Review section of last Sunday's New York Times. It's an article about technological advance and the "creative destruction" of capitalism (a timely topic, you might concur.) It starts with the (to me) exceeding provocative statement, "By some logic, there is no earthly reason why bicycles should still exist." It's a very interesting article, and (as is often the case with the NYT) so very timely on many fronts. (So go on, read it, don't worry, we'll still be here when you're done..)

The author, Catherine Rampell, makes the statement that "older technologies have survived by recasting themselves as luxuries and by marketing their sensory, aesthetic and nostalgic appeal." I wouldn't disagree with that, exactly, but Ms. Rampell does miss (or perhaps chooses to ignore) the point that bicycles do have a straight-ahead economic advantage: they are greatly less expensive to operate than automobiles for trips of a certain length, say daily commutes of 10 miles or less. There's just no comparison, and commuting bicyclists' blogs are replete with stories of how much money they've saved, ad nauseaum. Ms. Rampell might make the argument that such extra modality makes no sense, even if there are savings to be had. I would respond that I know of people who (even today) find cross-country driving more economical than flying, and do so for that very reason.

But I think the article raises an interesting question: what would it take to render the bicycle obsolete, at least as a practical means of transportation, or to marginalize it to such a degree that its only practical use is as a "fresh-air exercise machine"? I say this knowing full well that there are those of us "hard-core" individuals who will let you take our bikes only when you can pry our cold, dead fingers, etc., and it can reasonably be argued (by someone who lacks the personal daily joy of same) that bicycle commuting is inherently a fanatic kind of activity, even if economical.

Well, here's a candidate for a vehicle technology that might someday render the bicycle obsolete except for us fanatics: the Twill Wicked. What if you could have a highly safe personal transportation device, freeway-speed capable, extemely efficient (450-mpg equivalent, say), and capable of existing totally "off the grid", for which a solar panel of less than 4 square meters would suffice to supply energy for a daily 30 mile commute? What if this vehicle cost $12,000 (the price of a high-end carbon racing bike)? Such are the promised specifications of the Wicked.

To be sure, the Wicked exists right now somewhere between the gleam in the eye of an engineer and a partially-working prototype, no more. But the imagination displayed in this project is remarkable. (Allow me to step up on my soapbox a moment.) It is precisely the lack of this kind of imagination on Detroit's part that is at the root of their current death-throes. I mean, look at the ridiculous Chevy Volt, totally hobbled by the fact that it's designed around a superstructure based on cheap oil. As long as a car is assumed to be a ton-and-three-quarters hunk of metal, the battery requirements to get any kind of decent range will be excessive and costly. The problem is that, since this is what Detroit's "best and brightest" can come up with, this is what the public takes for an "electric vehicle". I don't assign any form of conspiracy theory here along the lines of "Who Killed the Electric Car?", rather I just think it's gross incompetence. (end soapbox) Maybe the the Wicked is what will replace the car, maybe the Aptera. Or a vehicle being brewed in any one of a thousand garages right now.

But I'm not worried about them replacing the bicycle. No time soon, anyway.
