Are Bromptons Worth It? An Honest Look at the Numbers

I get asked this more than any other question about bikes, and it usually arrives with a slightly embarrassed shrug. A thousand pounds. Fifteen hundred. Five grand, if you've been looking at the titanium one. For a bicycle with wheels the size of dinner plates.

So here's my honest answer, with the numbers laid out rather than hidden behind the folding-bike romance. I like Bromptons a great deal. I also think a lot of people buy one when a £600 hybrid would have served them better, and I think a few people talk themselves out of one when it would have been the best money they spent all decade. The difference between those two groups has almost nothing to do with the bike and everything to do with what you're actually going to do with it.

Let's do the maths properly.

What a Brompton actually costs

The range is wider than most people realise. There is no single Brompton price — there are five families, and they run from under a grand to nearly six.

	Price from	Weight from	Gears / wheels
A Line	£999	11.5kg	3-speed hub, 16"
C Line 4-speed	£1,399	11.3kg	4-speed, 16"
C Line 12-speed	£1,599	12kg	12-speed, 402% range, 16"
P Line 4-speed	£2,399	9.86kg	4-speed, 16"
G Line 8-speed	£2,599	14.8kg	8-speed hub, 20", hydraulic discs
Electric C Line	£2,999	17.3kg	4-speed + e-Motiq motor, 16"
T Line 4-speed	£4,769	7.95kg	4-speed, titanium and carbon, 16"
Electric T Line 4-speed	£5,999	14.6kg	4-speed + e-Motiq motor, 16"

Two things jump out of that table. The first is that the gap between the cheapest Brompton and the most expensive is nearly £5,000, which is a strange thing to say about bikes that fold to the same shape and are brazed by the same hands. The second is that weight and price move in opposite directions — you are, quite literally, paying by the kilo saved.

Brompton C Line 12-speed — the one most people end up with

£1,599, 12kg, and a 402% gear range that came in when Brompton retired the old 6-speed in 2025. It's the full-fat version of the classic: mudguards, front carrier block, folding left pedal, a proper colour range. If you only ever ride one Brompton, it'll probably be this. I've written a longer comparison of the C Line against the P Line if the weight question is nagging at you.

What you get back

Sticker price is the wrong number to argue about, because a Brompton is one of very few bikes where a meaningful chunk of what you pay comes back to you.

Resale is the big one. Used C Lines routinely fetch somewhere around £650 to £920 on eBay UK — that's an indicative sample rather than a market index, but it's the ballpark, and it's remarkably stable. Buy a C Line 12-speed at £1,599, ride it for four years, sell it for £750, and your real cost of ownership is roughly £850, or about £18 a month. Try that with a supermarket mountain bike, which is worth approximately its scrap value the moment you get it home. I've dug into how this works across the wider market in the bike value guide, but Bromptons are the outlier even among good bikes.

The warranty is seven years on the frame — but only if you register the bike through My Brompton. Don't register it and you get two years on the mainframe instead. That's a five-year difference for filling in a form, and I'd bet a fair number of owners have never done it. Components are covered for two years either way.

They're made in Greenford, West London. Not assembled from a container of parts — the steel frames are brazed by hand, by people, in a factory you could get a bus to. Brompton sold 78,530 bikes in FY2025. At that scale, keeping hand-brazing in a London suburb is a decision that costs money, and it's part of what you're paying for.

And then there's the fold. This is the bit that resists being put in a spreadsheet. Nothing else folds this small, this quickly, into this tidy a package that stands up on its own and rolls along beside you. Plenty of bikes fold. None of them fold like this. If your life involves a train, a lift, a flat with no hallway, or an office with a nervous facilities manager, that difference is the whole product. If it doesn't, you're paying for engineering you'll never use — and we'll come back to that.

When it's not worth it

Here's the part the brochures skip.

You are buying a heavy bike with small wheels. A C Line 12-speed is 12kg. A decent flat-bar hybrid weighs less, costs half as much, and will be quicker over any distance where you're not carrying it. Sixteen-inch wheels are wonderfully nimble and genuinely fine on decent tarmac, but they find every pothole and they don't carry speed the way 700c wheels do. If your commute is six miles of smooth cycle path and the bike lives in a garage at both ends, the fold is doing nothing for you and you've paid a premium for it.

Prices keep climbing. The 2025 changes brought a genuinely better bike — the 12-speed with its new rear frame and 402% range is the best-riding standard Brompton there's been — but the entry point to the classic C Line is now £1,399 and the flagship is £5,999. That's a lot of ground between "expensive" and "eye-watering", and it's moved in one direction for years.

The company itself has had a rough time. I'd rather tell you this than have you find it later. Brompton's FY2025 numbers were a turnover of £121.45m with a £2.1m net loss, and sales down 7.5% — 78,530 bikes against 84,899 the year before. The company called it a challenging year and it plainly was. I don't read that as doom: Brompton is a well-established business with an unusually loyal owner base and no shortage of demand, and the whole bike trade has been unwinding a pandemic-era hangover. But if part of your case for spending £2,000 is "they'll be around forever", that's worth knowing rather than assuming. Long-run parts support is one of the real arguments for a Brompton over a small-batch rival, and the honest version of that argument includes the accounts.

There are alternatives now. The one I'd actually point people at is the Flit M2i — £2,999, 13.3kg, 50km of range, Hope hydraulic brakes, made in Cambridge. That price is exactly what an Electric C Line starts at, which makes it the sharpest comparison in the folding e-bike market. I've put the two side by side in the electric Brompton comparison, and it isn't a walkover for Brompton.

The cheaper ways in

If you've read the case against and still want one — which is where I usually land — you don't have to pay full whack for a C Line.

The A Line at £999 — the same fold, fewer trimmings

This is the one people overlook, and I think it's the most interesting bike in the range. Same hand-brazed steel frame, same fold, same factory. What you give up: a 3-speed hub instead of 4 or 12, no mudguards, no front luggage block, non-folding pedals, a standard seatpost, and one colour. That's £400 of kit removed rather than £400 of quality removed, which is a very different proposition. If your rides are short and flattish, it's plenty of bike. I've compared the two in detail in A Line vs C Line.

Subscription from £35 a month

Brompton will rent you a C Line on a 12-month contract for £35 a month, or £50 a month on a rolling 30-day plan. The Electric C Line starts at £75. Theft and damage insurance is included, as is an annual service and delivery to your door, and after six months you can put a £200 voucher towards buying one outright.

Two caveats worth having in front of you. The insurance is void if the bike is left locked and unattended, which is their own small print and rather narrows what "insured" means for a city bike. And your bike may be refurbished rather than new — it's a fleet. I've gone through the full sums in subscription versus buying, and the short version is that it's a good way to find out whether a Brompton fits your life, and a poor way to own one for five years.

The used market

The same residuals that make a Brompton cheap to own make it a fine thing to buy secondhand. Around £650 to £920 gets you a used C Line, and because the frames are brazed steel and Brompton has kept parts flowing for decades, an older one is a repairable object rather than a disposable one. The Bickerton and Brompton story is a good reminder of how far back that lineage runs. Check the hinges, check the rear suspension block, and register the bike to yourself if the frame is still inside its warranty window.

Or spend more, deliberately

Two upgrades genuinely earn their money for the right person. The G Line at £2,599 puts 20" wheels, an 8-speed hub, hydraulic discs and tubeless-ready rims under you — heavier at 14.8kg and a bigger fold, but a far better bike on rough surfaces and for taller riders; I've set it against the classic in G Line vs C Line. And the P Line at £2,399 takes almost a kilo and a half off, which matters enormously if you carry the thing up stairs every day and not at all if you don't.

The verdict

A Brompton is worth it if you will carry it. That's the whole test, and it's a stricter one than it sounds. If the bike goes on a train, up a staircase, under a desk, into a boot, behind a sofa — regularly, not theoretically — then nothing else does the job and the price stops being the point. Factor in a resale value of roughly £650 to £920 and the real cost of a C Line over a few years lands somewhere near £15 to £20 a month, which is not much for a bike that turns an awkward commute into a good one.

If you won't carry it, buy a hybrid. You'll go faster, spend less, and enjoy it more, and no amount of admiring the hinges will change that.

For most people who pass the test, the C Line 12-speed at £1,599 is the right bike. If money is tight, the A Line at £999 does the important part for £400 less. If you're unsure, take the £35-a-month subscription for a year and find out. And whichever you end up with, register the frame — seven years beats two, and it costs you five minutes.
