A Kevlar layer inside the tyre offers excellent puncture protection. These tyres also feature a reflective sidewall stripe for excellent visibility at night.


  • Motor:  Wisper High efficiency, 250W hi torque brushless motor, easily ridden past 15.5mph with almost no motor drag
  • Throttle:  Standard: Thumb throttle to 4mph (6km/h) and Thumb throttle to 15.5mph (25km/h) when pedalling. Full throttle option available.
  • Throttle only range:  Using your Wisper bike on throttle only will reduce your range by up to 30%. If your bike has been upgraded so it works on the throttle only, we still suggest pedalling when you are able to do so. Use the throttle only function when you need to rest or to help you pull away when setting off.
