Rear Hub Motor 48V-72V 3000W

The Rear hub motor 48V-72V 3000W is a high-performance electric bike hub motor built for custom e-bike builds and serious off-road performance. Compatible with both 48V and 72V systems, this complete ebike conversion motor kit includes a DC controller, SW900 colour display, 8-magnet PAS sensor, twist throttle and brake cut-off levers. Available in 26 and 27.5 inch wheel sizes. The ultimate flexible 72V 3000W hub motor for builders who want motor performance without a fixed wheel aesthetic. Off-road use only. 6-month warranty.

The Builder’s Choice — Maximum Power, Maximum Flexibility

The Rear hub motor 48V-72V 3000W is the conversion kit for builders who know exactly what they want and prefer to source their own rims, spokes and wheel components to match their specific frame and build vision. Unlike the complete coloured MTX wheel kit variants in the All4eBikes range, this electric bike hub motor is supplied as a complete motor-and-electronics package — giving you the full power and control system of a 3000W conversion with complete freedom over the wheel and rim specification. Whether you are building around a specific rim brand, relacing into an existing wheel set or simply prefer to specify every component of your build independently, the Rear hub motor 48V-72V 3000W is the most versatile starting point in the All4eBikes 3000W range.

The motor is available in both 26 inch and 27.5 inch axle configurations, covering the two most common mountain bike wheel sizes and ensuring compatibility with the widest possible range of frames, forks and rim options. This size flexibility, combined with the 48V-72V dual voltage compatibility, makes the 72V 3000W hub motor genuinely adaptable to an unusually wide variety of custom build scenarios.

Dual Voltage Compatibility — One Motor, Two Power Profiles

The standout technical feature of the Rear hub motor 48V-72V 3000W is its ability to operate across the full voltage range from 48V to 72V without any hardware modification. This single specification opens up two meaningfully different performance profiles from the same electric bike hub motor:

• 48V configuration: Running the rear motor for ebike on a 48V system delivers strong, efficient performance well suited to builds where range and battery cost are priorities alongside power. The 48V platform has the widest battery availability in the All4eBikes range, giving you the most choice in pack size, form factor and capacity. The electric bike hub motor at 48V produces substantial torque for off-road use while drawing current levels that are manageable for mid-range battery BMS systems.
• 72V configuration: Stepping up to 72V unlocks the full top-end potential of the 72V 3000W hub motor. Higher voltage means lower current draw for the same power output, which reduces heat in wiring and controller components, improves sustained performance under load and delivers a noticeably higher top speed and more aggressive throttle response. The 72V setup is the recommended configuration for riders building primarily for maximum performance and speed.

This dual-voltage flexibility also gives the Rear hub motor 48V-72V 3000W an upgrade path that most single-voltage motors cannot offer. You can begin your build on a 48V battery system and later upgrade to a 72V pack to unlock additional performance — the motor handles both without modification.

Complete Electronics Package — Everything Except the Rim

The ebike conversion motor kit is supplied with a comprehensive set of control electronics. Every component needed to build a fully functional high-power electric bike — other than the rim, spokes and tyre — is included:

• Rear Hub Motor — 48V-72V, 3000W: A brushless, high-efficiency electric bike hub motor delivering 3000W continuous output with low noise, minimal maintenance and a long service life. Available in 26 inch and 27.5 inch axle formats to suit different frame specifications.
• DC Controller: Manages power delivery from the battery to the Rear hub motor 48V-72V 3000W across the full 48V-72V operating range, with integrated protection against overcurrent, overvoltage and overtemperature conditions. The standalone 48V-72V 45A eBike Controller is available separately as a replacement.
• SW900 Colour Display: A full-colour LCD display providing comprehensive ride data — speed, battery voltage, power output, distance, assist mode and more. A step up from standard monochrome displays and a fitting partner for a high-performance rear motor for ebike build. Also available as the standalone SW900 Colour Display.
• 8-Magnet Pedal Assist Sensor (PAS): Delivers smooth, cadence-based pedal assist alongside the throttle, enabling a natural riding feel as well as direct power-on-demand control. The PAS sensor is also stocked individually as a spare.
• Twist Throttle: Precise, direct control over the 72V 3000W hub motor output at any speed — essential for technical off-road sections where immediate power modulation is required.
• Brake Cut-Off Levers: Instantly cuts all motor power on brake application, a non-negotiable safety component at the speeds this ebike conversion motor is capable of generating.

How the Motor-Only Kit Compares to the Complete Wheel Kits

All4eBikes offers the 3000W motor system in two distinct formats — this motor-only kit and a range of complete MTX wheel kits available in coloured anodised finishes. Understanding the difference helps you choose the right product for your build:

The Rear hub motor 48V-72V 3000W supplies the motor axle, controller and electronics without a pre-built wheel. You source and build your own wheel around the motor axle — giving you full control over rim brand, spoke count, spoke material, tyre clearance and finished wheel weight. This approach suits experienced builders, workshop professionals and riders with specific rim requirements that the standard MTX wheel set does not meet.

The complete wheel kits — including the E-Bike Conversion Kit 3000W BLACK, E-Bike Conversion Kit 3000W RED, E-Bike Conversion Kit 3000W BLUE and E-Bike Conversion Kit 3000W PURPLE — supply the motor already laced into a colour-matched double-wall MTX alloy wheel, front wheel included, ready to bolt straight onto the bicycle. These are the faster, simpler conversion route for riders who want a complete, cohesive finish without custom wheel building.

Upgrade Path — Where the 3000W Sits in the All4eBikes Range

The Rear hub motor 48V-72V 3000W sits in the middle of the All4eBikes hub-motor power range — well above the entry-level 500W and 1000W systems, and one significant step below the top-tier 5000W motor. For riders working upward through the range, the Rear Hub Motor 48V-52V 1500W and the Rear Hub Motor 48V-72V 2000W are the natural preceding steps. For those who want to go further, the Rear Hub Motor 72V 5000W is the logical next level — a significant jump in output that requires a dedicated 72V battery system and robust frame and component specifications to match.

Battery Compatibility and Recommended Pairings

Matching the right battery to the Rear hub motor 48V-72V 3000W is one of the most important decisions in any high-power build. For 72V builds, the Triangle Ebike Battery 72V 30Ah 100A is the premium recommendation, offering 100A peak discharge and 30Ah of capacity in a compact triangle frame format — ideal for sustaining the demands of the 72V 3000W hub motor under hard riding. For 48V builds, the Triangle Ebike Battery 48V 35Ah provides excellent range and reliable high-current output to match the demands of the electric bike hub motor at full load.
