I have adapted my Kugoo V1 e bike for my disability so basically I have replaced the pedals with pegs and replaced the 36v battery with a 48v halong one, added a 500w 48v wheel and now I’m wiring in a larger controller in case I want to upgrade again. But I can’t work out where I connect the high level brake single cable to with the understanding that it is something to do with the regen. braking which I would like to have and extend the pads life. Can anyone possibly help me with this?
