**1. Product Title**
250W–750W Mid-Drive E-Bike Motor with Torque Sensor | CE Certified | Compatible with European Controllers | ODM Available
**2. Detailed Description**
This mid-drive e-bike motor is engineered for brands and assemblers targeting the European e-bike market. Available in 250W, 350W, 500W, and 750W configurations, it delivers smooth, natural power assistance through an integrated torque sensor that reads rider input in real time. The result is responsive acceleration, efficient energy consumption, and a riding feel that meets the expectations of European consumers.
The torque sensor system is the core of this motor's performance. Unlike cadence-based systems, it measures pedal force directly, providing proportional assistance that responds instantly to changes in terrain and rider effort. This makes the motor particularly suitable for city commuters, trekking bikes, and light cargo applications where control and efficiency matter more than raw power.
Compatibility is a key advantage for OEM and ODM customers. This motor is designed to work with mainstream European controllers, including those from Bafang, Tongsheng, and other widely used platforms. This reduces integration time and allows manufacturers to adopt the motor into existing frame designs and electrical architectures without extensive re-engineering.
The motor carries CE certification, meeting the regulatory requirements for electric bicycles sold in the EU market. It is available for ODM projects, with options for custom firmware, branding, connector types, and mounting configurations. Our engineering team supports the full development cycle, from sample validation to mass production.
Typical applications include city e-bikes, trekking models, compact cargo bikes, and retrofit kits. Whether you are building a new product line or sourcing a reliable mid-drive solution for existing frames, this motor offers a practical balance of performance, compliance, and integration flexibility.
