  • Strong Power: The engine boasts a robust 3.5HP horsepower, a displacement of 100cc, a rated power of 2kw/h, and a max rotating speed of 3600RPM, which provides you with strong power and accelerates your bike to a max speed of 50km/h.

  • Smooth install and solid power!
The engine started on the second pull. It fits my mountain bike perfectly and runs smoothly. The air-cooling works well even on long rides.
