Hi new to this so you may have to go slow,
I have a cyclotricity stealth 1000w. The problem is i like to take my bike through the woods and along woodland paths.
I have the de-restrict codes and they were working fine, now i seem to have a problem that when i try to change the codes back (for road use) the code goes in but it then puts out a max speed of 24.2MPH. that would not be a problem in its self i could live with what but when i de-restrict back to trail use it is still going 24.2MPH (when it should go 30ish). This is on a stand when turning the peddles and the thumb throttle(so no weight or road grip).
The worrying bit is i can put the bike on the ground use the thumb throttle and can hold the bike stationary cutting out the motor (could never do that before).
a little worried the motor on the wheel is giving up.
If anyone has some suggestions of what to try (please remember i am quite new to this)
I did change the battery and carrier (for the same spec)
brakes are good and new(ish)
and i put on a new thumb throttle
apart for new handle bar grips and a bell these are the only modifications.

Thanks

The problem is people illegally using woodland paths on a motorbike.

The code gives access to the settings. Did you actually change the speed limit to 15 mph and save it?

It's all a bit moot anyway because your motor is illegal. The police look mainly for 3 things to seize your bike. 1. Independent throttle. 2. Speed displayed over 15.5 mph. 3. Motor power. If you're good at blagging, you might get away with it if 1 & 2 are OK.
