With maximum lightness, the new Bosch drivetrain SX drive and uncompromising equipment down to the last detail, the Sonic EVO AM SX I offers the best of both worlds. As an ultra-light e-mountainbike in a class of its own, the Sonic combines sporty performance and agility based on a weight of just 18 kg with the support of a natural and powerful e-drive with the lowest possible pedalling resistance. The necessary energy is supplied by the particularly slim 400 Wh battery. If required, the range can be extended even further using the range extender, which can be easily mounted on the sophisticated Sonic carbon frame. In addition, the wireless Sram AXS 12-speed drivetrain, the RockShox Ultimate suspension, the Mavic E-Crossmax carbon wheels with robust Schwalbe tyres and the Proxim carbon saddle leave no doubt about the uncompromising equipment and sporty performance of the Sonic high-end all-mountain E-MTB.
