Hi everyone, just a quick intro,I live in Derbyshire area and been into ebikes for about 7years now, built a few in the past and atm I have a mountain bike ive converted myself running @ 72v 25ah with HS3540 crystalyte motor, sabvoton svmc 72100 controller and 200amp Bluetooth Ant BMS. I have only recently fitted the new controller and can't believe the power increase, it's scary at 100 amps lol. Anyway I'm looking forwards to using this site. Bye for now.
