The battery is a high quality power lithium-ion battery, 36V, 5.8AH. It will last approximately 60km. But that does depend on various factors, including terrain, slope, your weight and how much you pedal.
Yes. We find the vast majority of people don’t need a spare, but if you want to go on very long bike rides you can charge a spare battery and take it with you. You can purchase a spare battery in the shop page of this website.
Approximately 3 hours to fully charge. The battery comes with a charger.
The kit has an “intelligent assist control module” which works in conjunction with a gyroscope calculating the power you need. It will assist you automatically when you are pedalling. The motor will not work until the speed reaches 5km/h. The system will increase the power when you go uphill and will shut down the motor when you are going downhill. When you brake, the system can detect the decrease of the speed, and will stop the motor.
If you push the thumb throttle the bike will be fully driven by electric power, but when you release it the pedal assist system will kick in again automatically.
The entire kit weights 6.5kg. The battery is approximately 1.5kg.
The battery holder must be positioned at an upward slope, therefore it’s best to be fixed on to your bike-frame. This is because there is a gyroscope inside it, which is part of the pedal assist technology.
Wheel with 250W motor, battery & holder, thumb controller & digital display, mobile phone holder, spare brake disc, instruction booklet, tools for installation (allen key and wheel spanner).
No. The thumb controller is your choice. We find that some of our customers prefer not to use the thumb controller and that’s fine, the bike will automatically work on the pedal assist mode.
No, using your mobile phone is your choice. If you want, you can download the WePower app, where you can set the pedal assist mode, see the speed, temperature, battery level and mileage covered. But this is entirely optional, and the bike will function perfectly without it.
