Bromptons are great – and from the factory they’re perfect for what they’re designed for, short journeys around the city. But the Brompton design is capable of a lot more, with some modifications it can become the ultimate folding bike! Think of it like what Cooper did for the Mini – taking a very good bike, and improving it a bit 😉
I make a bunch of kits that can be bolted on to your existing Brompton to improve the gearing and brakes, or I can custom-build you a Brompton from scratch.
14-speed Rohloff hub gear kit – The Rohloff is the ultimate gearing system, a very wide range and incredible reliability and efficiency.- 8- and 11-speed Alfine hub gear kits – The Alfine hubs are good quality hubs which can also have a disc brake.
- Custom Brompton Order Form – Build up your dream Brompton!
- 8-speed Sturmey Archer hub gear kit – The Sturmey has a decent range, but the big advantage it it fits unmodified Brompton frames.
- Duomatic kit – A simple, minimalist kit that fits to unmodified Brompton frames to give two gears and a back-pedal brake.
- Disc Brake Kits – For much,much more powerful braking, and no more worn out rims.
- Electric Assist Kits for a bit of help with hills and headwinds.
- Front Pannier Racks – To carry normal panniers on the Brompton front luggage block.
- Custom Forks & Rear Frames – To do it yourself!
Hi. Will your 8 speed conversion fit a 1995 vintage Brompton?
It’ll be a bit of a squeeze because bikes of that age are 112mm not 115mm – but it will go, or you can bend your frame slightly to suit.
Hey Ben. Brompton has introduced a new colour in 2018 – Raw Black Lacquer. Have you tried matching it yet for a rear rack / front fork?
According to my powdercoater, it might be possible – but the raw lacquer finish looks a bit different on stainless steel anyway, it’s pretty hard to get an exact match.
Hi Ben,
I bought the rear rack with Rohloff speedhub. I did all the stuff by myself – not too difficult but twice a time the Allen key broke.
Now I like to ride my Rohloff Brompton every day. Worth every Euro I paid
Regards Karl
Great, thanks! I break a few Allen keys on those bolts too…
hello Ben,
I am riding your alfine 11 conversion now for a year and your Rohloff kit for almost half a year.
I am still thrilled about the improvement of your conversions.
Both hubs are fantastic and your stainless steel triangle with it´s fine brass seams
is a kind of an art, an eye catcher indeed.
I am riding my bromptons daily to work, no matter what season or weather, 26 Km one way,
hills included on my way.
I can only confirm that these conversions turn the bike into a grown-up touring bike.
I do not need no other bikes.
Thanks a lot, for these fantastic conversions.
All the best, Jörn
Hi there,
A few dumb questions:
1) I have a 10/12 year old Brompton that I am thinking of upgrading (gearing, brakes etc.) would this be something that (if shipped to you) you could upgrade? (Or is it better to sell that one and start again?)
2) Cosmetically the bike would also benefit with a fresh paint job (frame and accessories – wheels, handle bars). Is this something that could also be done?
3) Do you upgrade some of the bolts, clamps, easy-wheels etc. to titanium versions?
Sure, I can upgrade an older bike, including repainting it. Repainting starts from £200, depending on the colour. I can upgrade other parts at the same time if you wish.
Hello,
May I know whether you have Brompton (6 speed) in your store please?
Thank you.
Rgds,
Anna
I am not a Brompton dealer, I don’t stock normal Brompton bikes.
