The E-BikeKit Rear Wheel Conversion Kit (Battery Included) is a complete professional-grade rear hub motor conversion package 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 SINET™ controller, E-BikeKit 48V 15Ah lithium battery, and 3A smart charger. The external controller can be mounted separately from the battery, giving installers greater flexibility when planning the battery position, controller location, and wiring layout.

Who’s it for? Dealers, builders, and experienced installers looking for a complete rear wheel conversion package with a matched battery, charger, controller, display, and motor wheel.

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

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.

Battery Mounting Note:

The included battery is supplied with its standard mounting cradle. The installer must confirm that the bicycle or tricycle has a suitable mounting location and may need to provide additional mounting hardware or an application-specific battery mount.

The external controller design separates the controller from the battery cradle, giving installers greater flexibility when choosing battery location, controller placement, and wiring layout.

This architecture is especially useful for adult tricycles, cargo bikes, recumbents, and specialty applications where a conventional downtube installation may not be practical.

• Quiet, efficient SINET™ sine-wave controller
• Smooth and predictable throttle response
• Natural pedal-assist performance
• Flexible controller mounting options
• Separate battery and controller placement
• Easy controller access for diagnostics and service
• Matched to the included E-BikeKit 48V battery package

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
• Ideal for most conversion projects

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
