This bike is a project/ordeal I started about 6 months ago. Originally a 2012 Felt MP beach cruiser , this bike had the gas motor installed and a few months later the electric hub was installed. Bike is capable of operating by pedal, gas or electric or all three at once. The electric hub provides the torque and the gas motor provides the top end speed. A 50 tooth rear sprocket gives the gas motor a top speed of 35-40mph with a 200 pound man in the seat on level terrain. Top speed for the electric hub alone is 25-30mph. When both motors are used simultaneously, it is capable of climbing the steepest hills without pedaling and able to pull away from a dead stop at car speeds. I wish the gas engine fully recharged the batteries on the fly but it does not. It does, with brake regen and gas motor running, extend their range by over 300%.
