So what would you advise for my six speed Brompton to turn it into an electric version, looked at the switch, Arcc, not really blown away with them , the Brompton electric version seem to be stuck in the past as your little movie suggests, Digress just a bit = I was looking at Vello Rollof titanium bike yesterday none electric but Rolloff 14 gears and yes belt drive = when the hell is Brompton going to wake up ? If they spent just 10 % of the time they spend on which paint colour scheme for the next range we would of already had a belt drive system.
