  • The e-bikes rules state that the motor shouldn't be able to propel the bike at more than 15mph. Does that mean at 15mph the motor must cut out?

    I ask because there's some douc... I mean chap who rides his e-bike brompton with a 200 watt motor through hyde park at 25mph + and it aint his legs doing the work.

    ( I asked him what the wattage was, he reckons 250w which if so is not compliant, but I suspect he's just befuddled)

    On another note, why don't they rate the wattage on power to weight? a 2oow motor on a 8kg bike seems like madness.

  • why don't they rate the wattage on power to weight?

    The weight of the bike is irrelevant once you've added a rider.

  • Yeah true. Was wondering whether brompton brakes - and other light and shit equipment - would hold up to the speeds that could be achieved with an extra 200 watt behind you. But I suppose that's the same as wondering if they'd put up with a 'natural descender' on a steep descent.
