CE-certified BLDC hub motors and geared mid-drive motors for electric bicycles, cargo e-bikes, and light e-mobility.
The e-bike market reached 50 million units annually in 2024 and continues growing at 10%+ per year globally — with Europe and Asia-Pacific as the dominant markets. Each e-bike requires one traction motor plus several smaller auxiliary motors (display, light, lock actuator). This makes e-bikes one of the fastest-growing volume segments for BLDC motors.
E-bike motors split into two main architectures: hub motors (motor integrated into the wheel hub) and mid-drive motors (motor at the bottom bracket, driving the chain). Hub motors dominate in cost-sensitive commuter and city bikes; mid-drive systems are preferred in performance e-MTB and e-cargo bikes due to better weight distribution and natural pedal feel.
Regulatory compliance is critical: EU EN 15194 limits pedelec motor power to 250W continuous (with 500W peak assistance) at speeds up to 25 km/h. Speed pedelecs (S-Pedelec) allow up to 45 km/h. US Class 1/2/3 regulations specify different speed limits by state.
Geared hub motors use internal planetary reduction to allow a smaller, higher-RPM motor — lighter, more efficient at lower speeds, and with freewheel capability (no drag when not powered). Best for city commuter and folding e-bikes.
No gears — stator is fixed to axle, rotor is the wheel shell. Heavier but supports regenerative braking and higher sustained power. Popular for throttle-assist bikes and cargo e-bikes.
Motor drives the crank/chain, leveraging the bike's existing gearing for optimal efficiency across terrain. Better weight distribution for full-suspension e-MTB. Torque sensor integration standard.
48V systems deliver higher power at lower current than 36V — meaning thinner wiring, less heat, and better hill-climbing at the same rated wattage. Most modern e-bikes have moved to 48V. 36V remains common in budget commuter bikes and older designs. If you are designing a new e-bike, 48V is the recommended choice for any bike above 250W.
Our 250W rated hub motors comply with EU Regulation 168/2013 and EN 15194 for pedelec classification (power assist up to 25 km/h, 250W nominal). We provide CE Declaration of Conformity and can support your type-approval testing with motor technical documentation.
Our hub motors use standard 3-phase brushless with hall sensors (120° spacing). They are compatible with KT, Lishui, Votol, VESC, and BAC controllers. We can recommend a matched controller for your voltage, power, and display protocol (KT LCD, 860C, etc.).
Yes — 32H and 36H spoke drilling, and axle widths of 100mm (front) / 135mm / 142mm (rear quick-release and thru-axle) are available. Custom configurations have a MOQ of 50 units and 4–6 week lead time.
