Now that I received a 3-pin cable and the 555timer module, I made some progress. The waveform photo shows the output from the cadence sensor--roughly 7Hz, 25% duty cycle, 4.7v peak. I hooked the 555 module to the eBike's 5v supply and adjusted its output until it looked similar--but this did not...

I found the simplest possible solution. Simply short the two pins shown below using a momentary switch and a 1K resistor. The 1K resistor prevents the short from drawing too much current (4.5v drop across 1K = 5mA). You just need to tap the button a couple of times each second (say, 120bpm, for...

Thanks, but no. I don't want to pedal, period. (At least for the sake of this mod). Now I have proof that my idea will work. See my test: My square-wave signal generator module will arrive from Amazon this week, so I'll keep y'all updated.

I guess I should have said, "Legal issues aside..." :)

Just got my XP2.0, tweaked menus for best top speed and power, and rode around. With strictly throttle, speed tops out at 22mph, and if I pedal (at all), top speed is 26. That's fine, I'm happy with the top speed. However, at 26mph, I cannot pedal fast enough to engage the gears--this is a...
