Pedal-Responsive Power Assistance

The motor is designed to provide assistance according to the rider's pedalling speed.

The system activates automatically once the bicycle exceeds approximately 5km/h, then increases or decreases assistance according to riding conditions and pedalling input.

Assistance is designed to continue up to a maximum assisted speed of 25km/h / 15.5mph, allowing the system to complement rather than replace normal pedalling.

Battery & Range

The integrated 18V 10Ah lithium battery provides the power required for the motor and is designed for everyday commuting and recreational riding.

The manufacturer states a range of up to 50-55km / 31-34 miles on a full charge when using medium assistance.

Actual range will vary according to rider weight, terrain, temperature, riding speed, tyre pressure, road surface, assist mode and other conditions.

Smart App Control

The dedicated mobile app provides control over the power assistance system and allows riders to select from four assist modes.

The app can also display real-time riding information, making it easier to monitor your journey and battery usage.

Compact & Removable Design

Important Notes

The manufacturer states a maximum assisted speed of 25km/h and a range of up to 50-55km under medium-assistance conditions. Actual performance and range will vary depending on riding conditions and usage.

The motor relies on friction between the assist wheel and bicycle tyre. In rain, snow or wet conditions, reduced friction can cause the motor assistance to decrease or stop.

Please ensure the mounting clamp and adapters are correctly fitted before riding. Check that the assist wheel is properly aligned with the bicycle tyre and that all mounting hardware is secure.

This product is intended for compatible bicycles and should not be installed on bicycles outside the specified compatibility range.

Electric bicycle regulations vary by country and region. Check local requirements concerning motor power, assisted speed and road use before riding.
