Planet 3 would be my favorite as you do not interfere with the motor/electric at all. But I cant find the right version for Reign E+ 2022?
It's actually not that simple. The electronic delimiters are actually usually much better in fooling the software of the ebike's motor into thinking that everything is "normal". If a maker of a motor implements real anti tampering measures (like Bosch) they will of course easily detect the fact that there is a mechanical device that divides the signal from the magnet with some factor. Electronic tuning devices actually do the same thing but usually they try to be much smarter about it.
