Key Performance Factors

Range & Battery

Up to 100 miles of riding per charge and capable of well over 100,000 miles for the batteries lifespan.

Auto Mode

Let the E-bike do thinking, while you do the riding. Our new SmartAssist mode automatically selects the most efficient motor support for the terrain.

Quick Charging

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.
