The 46er 10D Speed is the same length as a regular bike and that's where the similarities end. Benno ditched convention and added capability - enough to make any cargo bike sweat. This unequaled combination of ride and capability starts with unequal wheels. 26" in the front for extra comfort, and 24" in the back for strength and a lower center of gravity. It also has front suspension for a sporty ride quality. All powered by the Bosch Speed 500Wh in-tube battery to assist up to 28mph.
