0, 1, 2 or 3: choosing your assistance mode
Mode 0 – Assistance disabled.
Mode 1 - Gentle assistance at up to 25 km/h that means you can forget about the weight of the bike - battery life of around 100 km under normal conditions.
Mode 2 - Moderate assistance at up to 25 km/h - battery life of around 90 km under normal conditions.
Mode 3 - Boost assistance at up to 25 km/h for the most difficult ascents.
