What OEM partners say

The CDD hub motors drop into our fat-tire frames without a redesign. Torque is consistent and the noise level is low enough for city bikes.

Voltage options and fast sample turns helped us lock a snow-bike program on schedule. Communication stayed clear from drawing to shipment.

North American off-road brand

Controllers and displays arrived matched to the motor. That saved our team a round of tuning before the first pilot build.

Questions from buyers

Answers to common questions about samples, lead time, shipping and payment.

How long does a sample or production order take?

Sample requests are reviewed on business days. After the drawing and voltage are confirmed, we share a build schedule. Production orders ship with a tracking notice by email.

Which voltages can you supply?

Standard hub motors are offered in 24V, 36V and 48V, depending on the model. Tell us the battery, controller and wheel size and we will match a motor.

Do you support OEM and custom specs?

Yes. Cable length, axle, spoke or one-piece wheel, power and torque can be configured around your frame and load.

How do you pack motors for export?

Motors are protected for sea or air freight, with cartons and pallets sized to the model. We confirm the packing list before shipment.
