New terrains, new frontiers 

Climb mountains while enjoying the scenery. Ride brilliant downhill routes while concentrating purely on the landscape. That's what Overvolt AM offers. It can cross mountains and redefine your limits. With 150 or 160 mm of clearance, you can tackle the most technical paths thanks to an electrical mountain bike developed with a centralised and lower centre of gravity. The result is a dream to ride and boundless pleasure.

Key Features

  • Supreme 5 aluminium frame with speed sensor and new UDH

    The same but better – Our OVV AM 6.6 frame in Supreme 5 aluminium retains rear clearance of 160 mm, 29”/27.5” differentiated wheels and the perfectly integrated fourth-generation Bosch drive unit. But it has been updated with a new rear triangle integrating the speed sensor and a new UDH (universal derailleur hanger).
  • Bosch system with fourth-generation Performance CX drive unit and 625 Wh battery

    A boosted drive unit – The fourth-generation Bosch Performance CX drive unit has numerous benefits: more compact and lightweight but no less efficient with drive unit torque of 85 Nm and an updated eMTB system. Combined with its integrated 625 W battery, you will be truly unlimited and get the absolute most from your outings.
  • Shimano Deore four-piston brakes

    Progressive power – The new Shimano Deore four-piston toe pieces combined with 203 (front/rear) discs will allow you to stop safely in any scenario and in as short a time as possible after a drop or to reduce your speed before taking a bend. With the smoothness and progressiveness the Shimano brakes are known for.
