9. BATTERIES / TECHNICAL SPECS a. Batteries specs As we consider that R&D is part of the E-MTB spirit, we don’t want to give other limitation than a daily Energy capacity per rider. For 2019, this capacity must be in the range of 1.950Wh up to 2.100Wh. Exemple : - Riders who have a bike with batteries of 500Wh will have 4 batteries per day (2 at the start + 2 at the refueling point). - Riders who have a bike with batteries of 650 or 700Wh will have 3 batteries per day (2 at the start + 1 at the refueling point). The Organizer will organize 1 refueling point per stage, where competitors will have access to their spare batteries that they will exchange with the used batteries. This point will be communicated with the final route in order to let the teams adapt their strategy and their timing in function of the location of the refueling point. b. Other information Exchange of batteries are allowed inside the team, for example if a rider is consuming less energy than his team-mate, but not with other teams even if they have decided to stop the race. Refueling outside of the official refueling points or battery exchanges given by friends, or left along the race track is strictly forbidden. Batteries will be marked during the scrutineering by painting.
