Trail etiquette with the eMTB

Be a fair eBiker and follow the same rules for eMountain biking as for classic mountain biking. In addition to adhering to the DIMB Trail Rules, the most important thing is respectful cooperation between mountain bikers, eBikers and hikers in harmony with nature.

Experience eMountain biking first-hand with Marcus Klausmann, Stefan Schlie, as well as Christoph and Jonathan from Bosch eBike Systems. You can decide which rider to accompany as you experience the Uphill Flow – Stefan as he rides uphill on a North Shore or Marcus, who chooses an easier uphill route, involving a harder push on the pedals at the start.
