Rear-Wheel Electric Bike Conversion System (No Battery)

The E-BikeKit™ Rear Wheel Conversion System (No Battery) is designed for riders who already own a compatible 48V lithium battery or are replacing an existing electric bike system.

This kit is built around a 500W nominal electric drive system operating at 48 volts with a high-output controller, delivering responsive real-world power when paired with an appropriate battery.

Rear-wheel configuration: This system is supplied as a complete rear motor wheel and requires selecting the following options to ensure proper fit:

• Wheel size
• Freewheel (7-speed standard, others available)
• Rear dropout spacing (OLD)
• Disc-brake or non-disc configuration

Rear wheels are assembled and dished to match your selected configuration. Because frames vary, some installations may require minor adjustments.

Who is this kit for? Riders who already have a compatible battery and want a high-quality replacement or upgrade system without purchasing a new battery.

• System type: Rear-wheel electric bike conversion kit
• Nominal power: 500W
• System voltage: 48V
• Peak power capability: Higher short-duration output for acceleration and hills
• Speed range: Varies by wheel size, gearing, battery, and rider input
• Total load limit: 300 lbs

No battery is included with this kit. It is designed to be used with a compatible 48V lithium battery supplied by the rider.

Battery compatibility depends on connector type, discharge capability, and mounting method. Common mounting locations include downtube mounts, rear racks, or frame bags when compatible.

If you are unsure whether your existing battery is compatible with this system, we strongly recommend contacting us before ordering.
