After riding my new Gygabike to work for the last week I can say I very much enjoy riding it. The carbon belt instead of chain is wonderful. I actually still get a good workout and get stronger despite the battery use. Took my old commuter bike for a 20 mile ride to the Farmers Market (Gygabike battery had to charge) and was faster than ever on it.The only thing I am a bit disappointed in is the low mileage I get out of the battery before having to recharge. Maximum was 14 miles so far. I mostly ride on pedal assist between 2-3, on short steep uphill I may go to 4 pedal assist. So not really a large power consumption, I think.
