Maker Faire - Bikes

|

Maker Faire features dozens of bike-related exhibits and demonstrations (see last year's entry, "Crazy fun bikes at Maker Faire". I only managed to make it to a small sampling of them today, but I hope to hit up some more tomorrow (e.g. Wooden Bikes).

I took the UM24 folding model out for a test ride. I've been denied boarding onto Caltrain more than once due to lack of bike space on the baby bullets, so a 49lb folding electric bike is quite appealing (the battery pack even quickly detaches if you want to distribute the weight more evenly). It was very different from the electric bike I currently own. My model requires you to manually control the throttle to get the power assist. The UM24 also has a throttle, but it also has a speed sensor that takes the bike up to full speed the second you start pedaling. It takes a second or two to get used to this immediate acceleration, but soon you're crusing around the fairgrounds having the time of your life. You can also get a torque sensor instead, which will make the power assist kick in more on the hills but less in the flats.

The model at Maker Faire used NiMH batteries, but the 2007 models are switching to LiON. The 2006 models are forward compatible with this update, but you do need to buy a new battery pack and motor -- probably not worth it until your NiMH battery pack runs out of juice.

Now that's an electric bike I can ride

Surfing the Web to find out if the General Wesley Clark for President rumors are true? Who cares? What I want to know more about are the WaveCrest electric bikes that Clark is promoting. In the past I've ridiculed a certain other electric bike because (a) it is designed to look like a dinky moped (b) it goes slower than my road bike (~22mph in the flats) (c) it is designed to look like a dinky moped.

WaveCrest's bike, on the other hand, (a) is designed on a mountain bike frame (b) gets up to 30mph (c) can be taken off road, possibly even mountain biking (one of its intended applications is military use). Also, the bike has pedals - though none of the videos actually show the pedals being used so I'm not clear as to how functional they are (though they are mounted on a triple chainring).

What else makes the WaveCrest special? Their key technology is advertised as an adaptive electric propulsion system that can reconfigure the torque/efficiency of the motor thousands of times per second. Their first application is a bike, as that is the easiest, but in the future they are eyeing the automotive industry.
