I am waiting for the wheels so I began some power use tests on the drive I have. It seems that going with the lower voltage actually helps with consumption. It causes me to pedal a lot more since the speed is lower. That helps add a lot of human power to the mix.

I think i can get four of five miles on a 12ah battery pack. Two of those would give me about 8 to 10 miles. That should be enough for someone to get to work if they have any interest in these bikes. I can't see anyone going more than 10 miles on a bike.

It would also be enough to take someone to the store or the doctor's office. Again only if they are even considering a bike. The person who is not an urban dweller wouldn't even consider a bike. This is really for urban transportation.
