Motorcycle like acceleration, and can sustain 40mph all day.

Nice! I almost sprung for that idea (pedal-assisted road-licensed electric like E-Rockit) before I bought a Zero. That battery looks pretty small, but I assume it's quite dense - what charge does it hold?

Pedals are there just for declaration. After 15mph the pedals don't do anything. Batteries are lithium polymer, very dense. 84 volts, and 740Wh

All you need a hub motor, controller, throttle, and battery.
