Step by step

Tap a step when it’s done to keep your place.

  1. Stop and cool down

    In the shade, switched off, until the hubs feel cool.

  2. Fix any drag

    Rubbing brakes and soft tyres both make motors work harder. Pump tyres into range.

  3. Change how you ride

    Lower mode or less throttle on long climbs. Short breaks on big hills.

When to take it to a shop

If it overheats on short, gentle, flat rides.
