Quality

Quality first, and a straight business relationship. Changdida Electromechanical Technology (Suzhou) Co., Ltd. designs, builds and sells hub motors, including spoke snow-bike motors and aluminum or magnesium one-piece geared motors.

Quality through the whole process

Quality control runs from design and purchasing through assembly, running tests and after-sales. The aim is a hub motor that holds its output, stays quiet and lasts in the field.

01. Design

Structure, electromagnetic design and prototype tests are used to improve output, efficiency, heat and stability before a model is released.

02. Purchasing

Magnets, copper wire, bearings and other key parts are checked on arrival. Suppliers are approved against the specification, not only against price.

03. Production

Assembly follows a written process. Finished motors are checked for output, noise and stable running before they are packed.

Promise

From raw-material inspection to the final bench test, each step has an owner. Production uses a controlled process, including SPC-style checks on assembly and test, so efficiency and noise stay inside the agreed window. Selection help and after-sales follow the same team that built the motor.
