Rear Hub Motor 36V 250W — Complete Road-Legal eBike Conversion Kit

A Calibration, Not a Compromise

This is not a compromise kit. The 36V 250W hub motor is built on the same brushless hub-motor architecture as the higher-powered systems in the All4eBikes range, delivering quiet, smooth and maintenance-free operation across thousands of kilometres of use. The 250W output level is not a limitation so much as a calibration — matched to the legal framework that allows the converted bicycle to be used everywhere a standard bicycle can go, without restriction, from the day it is built.

What 250W Delivers in Real Riding

Riders who have not experienced a well-built 250W rear hub motor conversion often underestimate what 250W of properly delivered electric assistance actually feels like on the road. At 250W continuous assist on a 36V system, the motor provides enough support to eliminate the fatigue of headwinds, flatten out moderate gradients and extend comfortable cruising range significantly beyond what the same rider could achieve on a purely human-powered bicycle.

For commuters covering 5 to 20 miles each way, this conversion transforms the daily ride from a physical challenge into a genuinely enjoyable and consistent experience — arriving at the destination without the sweat and exhaustion that unassisted cycling on the same route would produce.

A Genuine Touring Tool

For touring cyclists, this motor extends the daily range that loaded touring is comfortably achievable across, reduces the physical toll of multi-day rides on hilly terrain, and makes the conversion a genuine touring tool rather than simply a commuter upgrade. The quiet, smooth brushless hub operation means the riding experience remains as peaceful and connected to the environment as non-electric touring — the motor assists without intruding.

Complete Kit — What’s Included

Every component required to carry out a full, functional conversion from a standard bicycle to a working electric bike is included in the box:

Multiple Wheel Sizes — Fits the Widest Range of Bicycles

This motor is available in multiple wheel sizes, covering the most common bicycle wheel dimensions in use across mountain bikes, hybrid bikes, commuter bikes and touring bikes. Selecting the correct wheel size at the point of order ensures the motor wheel fits your frame’s rear dropout without modification, and that tyre, brake and mudguard clearances are maintained throughout.

Optional Display and Battery Add-Ons

This kit is available with optional display and battery upgrades configurable at the point of order. Adding a display provides real-time information on speed, battery level, assist mode and trip distance — a more complete and informative riding experience that enables precise assist level management for maximum range efficiency. The optional battery add-on supplies the energy source for the conversion in a form factor matched to the motor system, removing the need to source a compatible battery separately and ensuring voltage and connector compatibility from the outset.

Compatible 36V Batteries

For riders who already have a compatible 36V battery pack or who prefer to source their battery independently, this kit functions fully with any standard 36V lithium battery pack delivering sufficient continuous current for the 250W motor system. Two well-matched options from the All4eBikes range:

Warranty and Returns

Every Rear Hub Motor 36V 250W kit purchased from All4eBikes is covered by a 12-month warranty against manufacturing defects in the motor and all included components, alongside a 30-day return window for complete purchase confidence.
