The Kit

Electric start for the bike you already love.

How it works

Imagine a mechanical leg. That's exactly what's going on.

Using a high strength planetary gear reduction along with bevel and section gears, this gearbox turns the single direction output of a motor into a reciprocating, high torque mechanism capable of delivering the optimal torque and rpm needed to start your bike every time.

Why does this work?

Thanks to our patented design, the ES125 stays completely flush to the bike, and the complexity of the gearbox is isolated from fragile bike internals, all while maintaining full backup kickstart functionality.
