It is a great improvement over my last creation. Here are the specs:
24V/30ah LiFePo4 battery pack
24v/900w Currie motor w/15 tooth freewheel sprocket
90t #25 drive gear/sprocket
I don't know what other specs to post. This bike is really fast. Way faster than my Bianchi converson. I can hit 28mph on a flat, have hit 32.2 on a slight down, 25 is easy and it powers up most hills at about 17 mph. It is awesome. I love it.
I haven't tested the range yet but was able to go 11 miles on all electric and still registered 26.2V on the pack (not a good indication since lithium has a steep dropoff at the end).
Vroom. Vroom. Is it possible to get the speed up to 32-36 MPH? =D
It would probably improve the balance if you could mount the battery(or whatever on the rear rack) to the top tube. I wonder if that would improve the speed any. Hmm. Hmm.
