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; tire 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.
Motor |
SyncDrive Pro, 85Nm, powered by Yamaha The new motor is co-developed with Yamaha and optimized for the Reign E+ chassis and Maestro suspension. The compact motor is now lighter (2.7kg) with increased torque output (up to 85Nm) and significantly reduced noise levels. |
Sensor |
RideControl Ergo 3, grip integrated Six smart sensors precisely measure the power being applied to the pedals so the motor can provide just the right amount of assistance to create a natural, powerful riding experience. This helps optimize energy efficiency for both the rider and the battery system.

MAESTRO SUSPENSION TECHNOLOGY Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail. ADJUSTABLE GEOMETRY A flip chip lets you change the head tube and seat tube angles, along with the bottom bracket height, to fine-tune the handling. You can choose the low setting for faster, more open terrain, or the high setting for slower, tighter singletrack. |
