  • Do I need a mobile phone to operate my bike?

    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 double your range by charging a spare battery and taking it with you. You can purchase a spare battery here.
  • Do I have to use the thumb controller?

    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.
  • Can I put the battery in my pannier instead of attaching it to the crossbar?

    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.
  • Does the kit accommodate hydraulic brakes?

    Yes it does. The kit will automatically sense when the brakes are applied and cuts the power to the motor.
