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.
