Sorry it’s me again, I don’t have a mountain bike but with the gearing on your bike will you be able to get to 25-30mph?.
Also by unrestricting the bike you will lose around 50% battery life.
Have you tried the free unrestricted method first?.
Sweet as ill see how it goes this weekend thankyoupresumably you have a speed sensor on chain stay,
Magnet on crank arm, actually on end of pedals threads araldited into the Allen key hex on the end. The sensor is taken off from the standard position inside the chain stay and repositioned on the outside.
There are lot of video’s on YouTube
If your sensor is like mine you will need one of these https://www.toolstation.com/draper-security-bit-set/p52910.
