Onyx ST Ebike

Desert Camo

$3,299.99

Onyx is the top bike in the lineup. It has a mid-drive motor that climbs hills better than the rear-hub motors on our other bikes, plus full suspension and strong four-piston brakes. It's our most capable bike, with everything done right and nothing to add later.

Who this is for

  • Riders who want the most capable, fully-equipped bike.
  • Anyone who'd rather buy the top model once than upgrade later.
  • Riders who want strong climbing, full suspension, and smooth power together.
  • Riders who take on steep grades, rough ground, and long days.

MOTOR

Mid-Drive Motor for Climbing

  • Torque

    210 Nm

  • Top Speed

  • Rear Shock
