The Bosch eMTB Challenge supported by Trek 2022

Welcome to Europe's most exciting e-bike adventure, returning to the UK for the 3rd time in 2022…

You can look forward to varied trails against an impressive scenic backdrop. On average, you’ll have to cover some 30 kilometres and ascend around 1,000 metres. Riding technique will count just as much as orientation, fitness and intelligent battery management*. The stages, which offer a mix of uphill and downhill sections, are ridden against the clock without any prior training runs. In the transfer stages, the emphasis is on good orientation rather than just speed. It’s a real voyage of discovery!

The trails are designed for all levels of experience, whether you are a high-end professional or an e-bike newbie. Just choose from the two different categories; Advanced or Amateur.

*you should comfortably be able to complete the course with 1 fully charged battery – used wisely! However, batteries can be change, but must be carried by the rider.

Bosch eMTB Challenge Rules

“Just taking part in the first ever Bosch eMTB Challenge was a great experience. A fantastic course with stunning scenery and what a place to stop for lunch added to what was the help and encouragement from course marshals,” Phil Repton, 2019 Rider 

The Course


Downhill sections are an important part of the Bosch eMTB Challenge. The downhill stages lead down into the valley over bumps, stones, roots and steps. Here, a hard or an easy route can be selected depending on experience and performance level.


As well as fitness and motor performance, the uphill stages mainly test eBike riding skills. Obstacles and small steps challenge you just as much as tight corners. A ‘No Feet Zone’ after the start must be completed without touching the ground, otherwise a time penalty is applied. Afterwards, you can choose between a difficult route and an easy route on several sections of the trail.


There is no time measurement in the transfer stages, but your coordination skills are tested as these stages are completed according to a map. You’ll have to find various orientation points close to the track. For every missing point a time penalty will be added to the time recorded on the Uphill and Downhill stages.

In order to offer all riders the best possible flow experience, the trails are designed for various levels of difficulty: While beginners will have the opportunity to adapt slowly to challenging trails and fast bends, advanced bikers can prove themselves on shorter, but technically challenging track sections. Participants are not allowed to check out the stages in advance, but instead start the challenge ‘blind’ – so that anticipatory riding and spontaneous reaction to the trails is vital. Times are only recorded on the race stages and the individual sections are added together to get a total time at the end. The transfer stages between the stages are completed according to a map and without timing, so that the teams can enjoy the ride together and prepare for the next stage.

Entry options

From this season onwards, you’ll start in two competition categories:


In the “Amateur” category, the technical difficulty is somewhat lower so that hobby riders with some MTB experience can participate.


The “Advanced” category is mainly intended for experienced mountain bikers, you will be tasked with an additional, more demanding stage. You’ll also be required to ride a larger loop – a test of both your fitness and technical skills, where smart battery management will also be essential.
