Key Performance Factors

Smooth power delivery

The new SyncDrive Pro 2 motor delivers smooth, instantaneous power with 85Nm of torque to help riders climb steep hills and extend their trail riding capabilities.

Balanced, confident handling

Lightweight aluminum frame with trail-friendly geometry, 130mm of front suspension travel, and stable 29-inch wheels with tubeless tires puts you in control even in the toughest off-road terrain.

Long-lasting battery

Integrated EnergyPak Smart with 750Wh of capacity is easy to charge up to 80 percent in 2.5 hours with our 4A Fast Charger.

Range

How far can I expect to ride on a single battery charge?

The range for a single battery charge can vary greatly depending on conditions such as the combined weight of the rider and cargo; wind resistance; tyre pressure and tread profile; terrain and elevation changes; road or trail surface; outdoor temperature; maintenance of the E-Bike; and the condition of the battery.

The bar below gives an approximate range. Conditions are categorized as extreme, good and ideal. Extreme conditions typically occur when riding with a heavy load, strong headwinds or excessive climbs.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
