The E-BikeKit Rear Wheel Conversion Kit (No Battery) is a professional-grade rear hub motor conversion kit designed to provide strong traction, flexible configuration, premium ride quality, and simplified long-term serviceability.

Built around the latest SINET™ electronics, this kit delivers quiet sine-wave motor control, refined throttle response, smooth pedal-assist performance, and an intuitive full-color display. The rear motor wheel is configured by wheel size, rear dropout spacing, disc-brake compatibility, and freewheel selection so dealers can match the kit to the bicycle, tricycle, cargo bike, or specialty cycle being converted.

This version includes the external controller but does not include a battery or charger. A compatible customer-supplied battery and appropriate mounting system are required.

Who’s it for? Dealers, builders, and experienced installers who already have an appropriate battery solution and need a configurable rear wheel conversion kit for applications where traction, flexibility, reliability, and long-term support matter.

Every E-BikeKit Rear Wheel Conversion Kit (No Battery) includes:

• USA hand-built rear geared hub motor wheel
• External SINET™ sine-wave controller
• SINET™ 3.5" full-color LCD display
• SINET™ main wiring harness
• Thumb throttle
• Left and right mechanical e-brake levers with motor cutoff and parking lock
• Main motor cable
• Installation hardware, washers, and zip ties

Select your preferred pedal assist system:

• Cadence Sensor: PAS sensor with split magnet disc
• Bottom Bracket Torque Sensor: 68mm torque-sensing bottom bracket with required extension cable

Battery Required:

• This kit does not include a battery or charger.
• A compatible customer-supplied 36V or 48V battery is required.
• The battery must be compatible with the selected SINET™ controller configuration.
• The installer is responsible for providing a suitable battery mount and connection method.

Display Mounting Note:

This kit does not include a Topeak® BarXtender or other LCD display mounting extension. Most standard bicycle installations mount the display directly to the handlebars. Some bicycles and many adult tricycles may require an extension to properly position the display due to baskets, handlebar shape, or steering geometry. If required, the installer must supply an appropriate display mounting solution.

The external controller design is intended for builders who want maximum flexibility when choosing battery location, battery style, mounting arrangement, wiring layout, or future upgrades.

It is well suited for custom rear wheel conversions, replacement systems, adult tricycles, cargo bikes, recumbents, and specialty applications where controller access and serviceability are important.

• Quiet, efficient SINET™ sine-wave controller
• Smooth and predictable throttle response
• Natural pedal-assist performance
• Flexible controller mounting options
• Easy access for diagnostics and future replacement
• Compatible with an appropriate customer-supplied battery

This rear wheel kit is built according to the selected wheel size, rear dropout spacing, brake configuration, and freewheel. These specifications must be confirmed before ordering.

• Wheel Size: Select the correct wheel diameter for the bicycle, tricycle, or specialty cycle being converted
• Rear Dropout Spacing: Select the correct rear spacing for the application
• Disc Brake Option: Choose the correct disc-brake or non-disc rear wheel configuration
• Freewheel: Select the freewheel required for the customer's drivetrain
• Torque Arms: Must be installed where required for safe rear hub motor installation

If you are unsure of the correct wheel size, rear dropout spacing, brake setup, or freewheel selection, contact E-BikeKit technical support before ordering.

Cadence Sensor

The standard cadence sensor detects crank rotation to provide dependable pedal assistance that is simple to install and compatible with most bicycles and tricycles.

• 12-magnet split-disc design
• Simple installation
• Reliable everyday performance

Bottom Bracket Torque Sensor

The optional torque sensor measures rider pedal force to deliver assistance that feels smooth, proportional, and more natural than traditional cadence-only systems.

• 68mm square-taper bottom bracket
• Includes required SINET™ extension cable
• Power output responds to rider effort
• Premium riding experience

The included SINET™ 3.5" full-color LCD gives installers and riders access to advanced programming, diagnostics, and real-time ride information.

• 3.5" full-color display
• USB-C charging port
• Battery voltage display
• Battery level indicator
• Current speed
• Trip meter and odometer
• Pedal-assist level selection
• Walk-assist mode
• Error diagnostics
