Our E-assist system is designed to provide extra power when pedaling alone is not enough.

Whether carrying Pedicab passengers or heavy warehouse loads, the Coaster E-assist was developed to handle a variety of situations.
Designed for adjustability, with three main power settings available: Economy – up to 500w, Legal – ~500w – 750w, and off road – 750w – 1650w and higher.

E-Brake Cut Off

Both front and rear brake levers cut power to motor when squeezed

E-Assist

E-assist is standard programming where motor output is determined by rider pedal input (light pedaling gives low motor output, heavy pedaling produces higher motor output to match demand)
Optional ambidextrous thumb throttle

Drive Train

Motor is linked to the rear differential via heavy duty1/2” pitch bikechain with 14 tooth free wheel sprocket on motor to a 36 tooth stainless steel rear differential sprocket
No E-power is run through the pedal drive system, so no concerns of premature pedal drive train failure
