The E-BikeKit Front Wheel Conversion System – No Battery is designed for riders who already have a suitable 48V battery or need a replacement conversion system without purchasing another battery.

Built around the latest SINET™ electronics, the system combines quiet sine-wave motor control, refined throttle response, your choice of cadence or torque-sensing pedal assist, and an intuitive full-color display.

Because the motor is installed in the front wheel, your existing rear wheel and drivetrain remain unchanged.

Description

Front-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, and specialty applications where a compatible battery is already available.

The motor wheel installs in a compatible front fork with standard 100 mm dropout spacing, allowing the rear wheel, gearing, and drivetrain to remain unchanged.

Ordering is simple: choose the correct front wheel size and select either cadence or bottom bracket torque-sensing pedal assist. Front dropout spacing is always 100 mm for this system.

Front wheels are USA hand-built using 12-gauge stainless steel spokes and double-wall aluminum rims.

Who is this system for? Riders who already own a compatible 48V battery and want a high-quality front-wheel conversion or replacement system without purchasing another battery and charger. Recommended total load is up to approximately 300 lb, depending on the bicycle and application.

What’s Included

USA hand-built front hub motor wheel in the selected wheel size
External SINET™ sine-wave controller
SINET™ 3.5" full-color LCD with USB charging port
SINET™ component wiring harness
Thumb throttle
Left and right mechanical e-brake levers with motor cutoff and parking lock
Motor cable
Battery wire harness / pigtail for connecting a compatible 48V battery
Torque arm(s), washers, zip ties, and installation hardware as required

Your pedal-assist selection determines the sensor included:

Cadence Sensor: Left-side external cadence sensor with 12-magnet split disc
Bottom Bracket Torque Sensor: 68 mm square-taper torque-sensing bottom bracket with required SINET™ extension cable

Not Included: Battery, charger, and battery mounting system.

Display Mounting Note: A handlebar extender is not included with this universal system. Most standard bicycles can mount the LCD directly to the handlebars. Some bicycles and many adult tricycles may require a separate display mounting extension because of baskets, handlebar shape, or steering geometry.

SINET™ External Controller System

The external-controller version of SINET™ is designed for riders and builders who want flexibility in battery choice, mounting location, controller placement, wiring layout, and future service.
