Riding fun plus endurance

The E-Tremalzo offers a powerful performance – thanks to Bosch Performance Line CX drive unit and a full 85 Nm of torque. And thanks to the large, fully integrated 500 Wh battery, it won't let up even if your tour turns out to be longer than planned ... because it's just so much fun. Also "to blame" for this: our comfort geometry of the lightweight aluminium frame, full connectivity between rider and bike thanks to Bosch's "The Smart System", the sensitive SR Suntour suspension fork and versatile Schwalbe Smart Sam tyres.

  • Entry-level e-hardtail w/ trail-worthy geometry
  • Smooth Bosch G4 Performance Line CX drive unit w/ integrated 500 Wh battery
  • SR Suntour 120 mm suspension fork w/ thru-axle
  • Precise SunRace/Shimano Deore 10-speed drivetrain
