About the E-Go Thumb Throttle This thumb throttle is compatible with all E-Go e-bikes and allows the bike to be powered without pedalling. Choose Fitted if you would like the throttle installed before dispatch, or Loose if you would prefer to fit it yourself. Please note: throttle use without pedalling may affect the bike’s road-use status. Unless the bike has the correct approval and any required registration, insurance, tax and licence requirements in place, throttle use should be limited to private land with the landowner’s permission.
