Plug and play Regen button (for X1 spark/Aipas) or any bike with M8 male 2pin brake sensor

🔥 we had mastered and made the first ever regen button for the X1 spark/ aipas s1. 

✅most people have switches but with our first ever button it will be more convenient for pressing it and letting go instead of flipping a switch every time.

🔋 this will keep your battery charged way more than it was before our regen button delivering clean power!
