Rear-Wheel Electric Bike Conversion System – No Battery
This version uses an external SINET™ sine-wave controller, giving you flexibility in battery choice, battery location, controller mounting, and wiring layout. It is well suited for new conversions, replacement systems, adult tricycles, cargo bikes, recumbents, and specialty applications where a compatible battery is already available.
Rear-wheel configuration: Use the selections on this page to configure the motor wheel and pedal-assist system for your application:
- Wheel size
- Rear dropout / brake configuration
- Freewheel
- Cadence or bottom bracket torque-sensing pedal assist
Rear wheels are USA hand-built using 12-gauge stainless steel spokes and double-wall aluminum rims. Correct measurements and selections are important. If you are unsure about fitment or battery compatibility, contact us before ordering.
Who is this system for? Riders who already own a compatible 48V battery and want a high-quality rear-wheel conversion or replacement system without purchasing another battery and charger.
