RYUGER Shimano DU-EP801 Drive Unit

The Shimano DU-EP801 Drive Unit is a high-performance mid-drive motor engineered for modern e-bike platforms, delivering a refined balance of power, efficiency, and control. Designed to be mounted in the bottom bracket area, this mid-ship configuration ensures optimal weight distribution and a natural riding feel, making it suitable for both performance-focused riders and everyday use. This EU-spec version is electronically limited to 25 km/h, ensuring full compliance with European and Japanese regulations for road-legal electric bicycles. Supplied in bulk OEM format, it is intended for manufacturers and professional builders, rather than retail sale, and is delivered without standard consumer packaging. The DU-EP801 produces up to 85 Nm of torque, offering strong and immediate power delivery across a wide range of riding conditions. With a 250W nominal output and a 36V system, it delivers efficient performance while maintaining regulatory compliance. Weighing approximately 2.7 kg, the unit remains lightweight within its class, contributing to improved handling and overall ride dynamics. As the evolution of the EP800 platform, the EP801 introduces enhanced connectivity and more advanced tuning capabilities. This allows for precise adjustment of assist characteristics, improved system integration, and a more refined riding experience tailored to both OEM builds and high-performance applications.
