brompton

On a couple of Bromptons over the years, I've had irritatingly frequent rear punctures, always when the bike is parked, that are traceable to a badly-finished rim hole. The sharp edge chafes at the base of the valve stem, presumably as the tyre deforms under pedalling forces, and then deflates...

I wander if anyone ordered a kickstand for a Brompton from Bike Gang. It's only £198.00 (USD 262) No, you don't get a bike. Just a kickstand. Brompton Aluminum 6061T651 CNC machined Ultra Strong Kickstand (COLORPLUS)

Good day all. I'm starting a new job very soon, and the easiest, fastest and cheapest way to get there is by train (LNER / Transpenine Express) with a bicycle and a shortish ride of a few miles at either end. This will be my first time commuting by train or bicycle apart from a year or two in...

I find Brompton pedals to be OK but I always wish for something better and probably grippier too. Does anyone have experience with upgrading pedals on Brompton? There are some models with quick release, but then where to store removed pedal. Any good upgrades with foldable design?

Brompton have posted a video about replacing the wheels on the P line 4 speed. View: https://www.youtube.com/watch?v=gG6kmlVMftg

Preferably M bar with guards, carrier and rack, but what do you have? I know long shot, but new are just too expensive Cheers

I like good lights and don't like when bike light beam is designed as flashlight. I understand that lights for mountain bikes and road bikes serve different purpose and I think lights need to be marketed as such. I also like StVZO certified lights not only because they don't blind incoming...

So, like many people, I’ve not ridden my Brompton much over the past year and a half. We’ve only been going in to the office for a couple of months and only occasionally at that. Anyway. I’ve been thinking that it sounded very ‘graunchy’ at the front end. I put it down to the fact that...

Has anyone used one of these Spa Cycles super-compact doubles on their Brommie? I've just changed the BB for a Shimano UN55 118mm so would prefer to not have to replace it again -- but how to know if the Spa double will work out ok (ie not interfere with folding etc)? N.

Brompton just changed their notation of model names. What used to be "a Brompton" is now a "C-Line", 2-speed ist now called "urban", 3-speed "utility" and 6-speed "explore". The B-75 is now the "A-Line" (and black/white instead of blue). S-bars are now "low", M-bars are "mid" and H-bars are...

I'm planning on riding the Wild Atlantic Way and I have two bike options. The Brompton would be very convenient as I have to fly from and to California as well as from London to Cork and Londonderry to London. But I'm worried about getting repairs if I have a mechanical. I only see the one...

I have an elderly, 20 year old M3. When folded, as soon as it is picked up the front wheel and bars will come loose and swing out. The hook is intact, and the the stays for the front mudguard aren't bent. Any Ideas please.

I was looking at some third party kits to convert regular brompton to electric. Price wise they are not great. When added to new bike cost, most of them go over new electric brompton price. There is really no financial initiative to modify new out of factory regular brompton. On other hand I had...

I have Marathon Racers on my Brompton now, and due to ample rain in the spring this has been the worst year I can remember for Goatheads, the uniquitous natural caltrops found in the western states. Based on advice from my LBS, I used an ounce or so of tubeless tire sealant each in the tires...

I know many have done many more miles on their Brompton, but today I did my farthest cycle on my Nine Streets. For anyone who wonders whether these amazing machines can be used for anything other than a short (commute) distance, I have to say, they really are fine. I had some well worn...

I had an Email from Brompton a couple of days ago. It seems that stock levels are getting better as there are several models listed for order on their website. What did surprise me is the price, perhaps I'd lost touch but they do seem to have increased a fair bit recently ( perhaps that is as a...

There's an excellent YouTube channel created by Pam and Gilbert, a couple of folding bike enthusiasts. Loads of really useful information that's exceptionally well presented. The lates upload compares the performance of a Brompton compared to a road bike, interesting and informative. View...

I was looking at this section and 9 out of 10 threads had Brompton in the title. I live in the hills, so really need a little assistance, so wanted an electric motor, but wife's e-bike is over the 20 kg and bike rack able to be used same time as towing has a limit of 40 kg, plus it means only...

I often wondered why other companies did not start copying the Brompton once the patents ran out. It looks like they have. There are at least three brands that look like direct copies: Mobot, Pike (Pikesei) and 3Sixty. Presumably they are all cheaper than Bromptons. I wonder what that means for...

I have an excellent floor pump (Topeak JoeBlow) that does not work well with a Brompton because of the narrow space between spokes. The chuck simply won't fit between them. I have a crappy floor pump with a narrow chuck that fits just fine. Does anyone have a recommendation for a good floor pump...

I have a six-speed and I notice the Brompton toolkit has a chain breaker. But it looks like if I remove a bad link the chain will be 1" shorter and I won't be able to get it back on the bike. There isn't enough slack in the tensioner. Am I wrong? Is there a clever trick I need to know about?

Ok...how are you supposed to open the "tool free" battery compartment when the light is bolted to its bracket? Am I missing something?

Anyone has any ideas of pre-assembled one? Or on a part by part basis? The goal of such toolkit is to perform small to medium repairs such as mounting mudguards, rack, replacing a wheel, etc. What are the most used tools? Looking for something relatively sturdy, what would last more than 2-3...

Hello. My Brompton main frame hinge pin is worn, probably from the previous rider not being able to tighten the clamp fully causing wear. Anyway, it's not expensive to replace except I can only see shops in London that can replace the pin. Anyone know of a shop in the North East that can do...
