I agree there needs to be a better measuring gauge. The folks on the 36v system say that it's 20 miles at 20 mph or 1 hour on level ground.
I think these e-bikes are kind of neat, but man 70lbs. How's it do on the hills? I'm old school human bike power. I need to google these, it may be an interim for someone not used to propelling themselves yet. Oh, here's some data for you. 25mph on a road bike requires about 425-450 watts. On a recumbent you need about 250watts. Aerodynamics are everything, have you thought about going aero, or using the propulsion system off the ebike in a more aero design? 23mph fully upright tells me you probably have around a 1/2-3/4hp motor?
