Performance

The 1500W brushless gearless motor is designed to provide strong acceleration and efficient power delivery for e-bike conversion projects.

With a rated speed of up to 500 RPM and maximum torque of 55Nm, the motor is suitable for riders looking for a higher-performance rear hub motor setup.

The gearless brushless design eliminates mechanical gears and carbon brushes inside the motor, reducing mechanical friction and routine brush maintenance while providing smooth power delivery.

Smooth & Quiet Operation

The brushless gearless construction is designed for smooth operation with reduced mechanical friction.

The manufacturer specifies an operating noise level below 55dB, helping provide a quieter riding experience compared with more mechanically complex motor designs.

Durable Construction

The motor uses an aluminium housing with iron, copper and magnetic steel components. The housing is designed to protect the internal motor components during normal use.

The manufacturer also states that the motor has undergone a salt fog test for corrosion resistance.

Bicycle Compatibility

The motor is designed for:

• Wheel Sizes: 20-28 inches
• Rear Dropout: 135mm
• Brake Type: Disc brake
• Freewheel: 5, 6 or 7-speed
• Spoke Count: 36 holes
• Applications: Conventional bicycles and suitable mountain bikes
• Excluded Application: Snow bikes

The frame, dropout spacing, brake setup, wheel dimensions and freewheel configuration should be checked carefully before purchase.

Important Notes

This listing is for the rear hub motor only. A compatible controller, battery, display and other components are required to create a complete e-bike conversion system.

Please confirm your bicycle's rear dropout width, wheel size, spoke configuration, brake type and freewheel compatibility before ordering.

The stated 1500W rating, 500 RPM speed and 55Nm torque are manufacturer specifications. Actual performance will depend on the controller, battery, wheel size, rider weight, terrain and overall conversion setup.

A 1500W motor may exceed the legal power limits for electric bicycles in some jurisdictions. Check applicable local regulations before installation and use.

Professional installation is recommended if you are unfamiliar with e-bike electrical systems or wheel building.
