I don't know but I like the idea that they are small. I wonder what the voltage is on the 2.2 ah battery. three of them would get you only as much as 6 1/2 ah at whatever the voltage is of one. That makes it the size of a sla battery. If they can get the weight down of the batteries, the amps up and the cost down then building ebikes will be worthwhile.

I prefer ebikes except for the wow factor. In theory they are a better build project. The pure kit (hub wheel) is a bit pricey for me. There isn't much reason for that kit to cost more than 200 bucks in my opinion. Electric motors require less maintenance than these gasoline beasts. They are quieter, smell better, and you don't smell of gasoline all the time.

The problem is the battery technology.it might come along now that there is a greater push for alternate energy sources.
