The Year of the E-Bicycle
theodp writes "Electric bicycles have been around for more than a century, but they have never quite captured the imagination of auto-obsessed Americans. That may be about to change. At CES this month, Sanyo showed off its sleek, lightweight Eneloop Hybrid Bicycle. Priced at $2,300, the e-bike sports a black lithium-ion battery strapped to the frame beneath the seat. Press a button on the left handlebar, and a 250-watt motor kicks in, providing about twice as much power as your own pedaling. Some basic e-bike models, like the Ezip Trailz can be had for as low as $500. Both Trek and Schwinn began selling e-bikes last year, and Best Buy is offering e-bikes in three test markets: Los Angeles, San Francisco, and Portland, OR."
I love the idea of using one of these bikes for my daily commute to work and back, however they don't come anywhere close to solving the beer bottles from pickups aimed at cyclist problem, or the Houston has no safe way to ride a bike much of anywhere problem.
I love to ride my bike, but Houston is a city built by politicians with pockets lined from oil companies. The oil companies decided people in Houston should drive individual cars to get around and dammit, the politicians not only saw that it happened, they made sure the public transit system sucked as well. Sure there's a great bus to get downtown and back, but you still have to drive locally to the bus stop, even if it's only a mile or two away unless you want to become road pizza. Then it's only to downtown, not across town. You can go around your area, you can go downtown, but getting from one area of Houston to another isn't easy, and unlike Phoenix and certain other cities putting a bike on a bus is hit and miss. Some drivers forbid it if they don't have a bike rack and bike racks are rare.
The preceding post was not a Slashvertisement.
The price point for these seems way off.
In China, riding an electric bike conveys professional achievement, even a certain degree of wealth. People in the United States, said Ed Benjamin, an independent consultant in the bike business, don't quite know whether these bikes are fashionable. The e-bike is "an ambiguous statement," Mr. Benjamin said.
I'm not entirely sure what the cultural significance of that is, but it must mean something.
Qxe4
We had those here (Japan) for 5 years now, they're quite popular in rural areas or for shopping but otherwise everyone takes the train.
Probably Lance Armstrong can produce over 250W for much of a day. I on the other hand, break a sweat just thinking about it. A hardworking horse can keep up about 750W (definition of a horsepower). Imagine yourself and two buddies playing tug-of-war with a Clydesdale.
Because of the anger among the cyclists, Critical Mass was started which generally only pisses off the drivers but also is a lot of fun.
And you wonder why so many drivers get pissed off to the point of violence? Golly gee, I can't imagine how that could happen.
The correlation between ignorance of statistics and using "correlation is not causation" as an argument is close to 1.
Surely humans can produce well in excess of 250W.
Yes. 250W is only "twice as much power as you provide" if you're taking it very easy. Based on measurements provided by the exercise bikes at my gym, I know I'm able to produce around a kilowatt for 5 minutes or so at a time, and can sustain 500W practically indefinitely.
OTOH, there are regulatory reasons for the motor being 250W: at least here in the UK, you'd need a full drivers licence, annual vehicle inspection and all-around crash helmet to ride it if it were more powerful. It should also be designed so that the motor cannot make the bike go faster than 15mph.
Errr... according to this:
Lance Armstrong can ride up the mountains in France generating about 500 watts of power for 20 minutes, something a typical 25-year-old could do for only 30 seconds. A professional hockey player might last three minutes and then throw up. (source)
...it sounds like you're either an olympic-level athlete... who reads slashdot... or your gym equipment is severely miscalibrated. I've tried those bikes at the gym, and 250W is
my limit for a 10-15 minute stretch, and I'm by no means unhealthy. Are you sure those weren't imperial units? I know the UK has switched to metric, in theory, but I know some of you poms still get confused. 8)
