It si posible to buy a BIRDY ROHLOFF whith no dinamo and not very nice lights?
Thanks
They don’t offer that, no.
You’ve customized (and posted about) so many amazing Bromptons. My question is, how significantly can you reduce the weight of a Birdy Rolloff? I ask because for me (and my back), lifting a (relatively) heavy Birdy into and out of the trunk of a car is a chore.
Not an awful lot, I’m afraid – it’s already an aluminium frame, with reasonably light components. You could go down a rabbit hole of fitting carbon cranks, bars, seat post etc, spending a lot of money without saving much weight. Basically, it’s got a 1.8kg hub in the back wheel, nothing much can be done about that.
Thanks. I feared that was the case and appreciate your confirmation.
Is it possible to alter a Birdy to use a Gates Belt Drive?
I’m not sure it would be very successful – could maybe adjust the belt tension with an eccentric bottom bracket, but it’d need some kind of belt keeper for folding.
