Bypassing speed limiter electronically
Hi guys. I recently bought a Stromer and I am loving it. But the 20mph speed restriction is really bugging me. When the bike hits 20mph it has so much more to give, and I'd like to be able to get a few more MPH out of it.
So, for those of you who are electrically inclined, do you know how hub motors in general measure speed? I think if I can trick the computer into thinking it's going slower than it actually is, that should do the trick. Is there a "speed" wire coming out of the motor that sends a signal pulse to the controller, for example? If that's the case it would be easy to make an inline gadget that slowed down that pulse to a percentage of its original frequency.
Just thinking out loud here. Any suggestions?
