Conquers new mountains

  • Lightweight and sexy

    Thanks to its low weight, the JAM² can climb every mountain – and it will do it in style. The e-drive is perfectly integrated into the down tube and very little energy is wasted thanks to the low weight of the bike.

  • Optimal suspension performance in any situation

    Our F.O.L.D. chassis has been specially designed to meet the increased demands placed on e-MTBs. This means that we can also guarantee the perfect mix for the e-All-Mountain JAM²: F.O.L.D. is extremely sensitive while being progressive enough to prevent a harsh bottom out.

  • Handling characteristics matter

    We use only those drives and batteries that enable us to create a modern, agile and aggressive geometry for the JAM² thanks to their compact construction. This means that you will have just as much fun out on the trail as with our non-electric JAM.
