This is the part of your ebike thats works like an on off switch for the motor. Meaning the assistance will only kick in as you are pedalling and will disengage the motor when you stop pedalling. Clever little sensor 🙂
It is located on the bottom bracket near the pedals of your electric bike. As you start to pedal the bike will sense the pedals are turning and depending on the level selected (1 being the minimum and 5 being the maximum) will assist you a little bit or a lot. The choice is yours. Simple select the level that is right for you using the control display at your finger tips using the up and down buttons.
Replacement pedal sensor for Roodog electric bikes. Please select model you require.
