Great product. The bicycle works like a charm. The only bad side on my Rocky Mountain. It shows a wrong speed. On my KTM Bosch Bicycle it shows the actual speed. In this one it shows 14MPH ehen we were doing 30 MPH.

The supplier’s service is excellent but in reality the engine cuts out at 40 km/h. and not 50 as in the description. However, I am more than satisfied with the seller. Perfect service.
