Brompton M-type Review

It’s been over a month now since I bought my new-to-me Brompton, during which time it has been used extensively. I feel I have now had enough experience with it to do a proper review, you can read my initial impressions here.

The main event when looking at folding bikes for many is the fold itself. As is shown in my original post, the fold is neat and compact and the oily chain is tucked away in the centre of the package. Unlike most other folding bikes I’ve used, it doesn’t try to come unfolded whilst being carried, which is one of the best aspects of the design. Once you have got the hand of it, you can fold the bike in little more than a few seconds, with unfolding taking little longer. This is ideal because although the folded bike is compact and forms a sturdy package, you wouldn’t want to carry it folded up for any serious distance. There are lighter options available, but realistically even they won’t make carrying the folded bike for any length of time much more pleasant.

I have ridden the bike over reasonable distances on several occasions (several trips from Macclesfield to Manchester), and the compact and clever folding ability of the bike does not diminish the ride. The wheel-base makes the bike feel like a much larger bike when ridden, which gives a better experience than many of the other folding bikes I have tried. The ride quality is similar to the Raleigh Twenty, although the steering is a bit more twitchy at lower speeds. The M-type bars give a reasonably upright posture, although the fact that the seat-tube does not terminate at the bottom bracket means that the virtual seat-tube angle gets steeper with saddle height. This can be corrected to a certain extent by moving the saddle fore/aft.

The stock gearing is reasonably broad, although a wider range would be desirable, and is available in the form of the 3-speed hub & 2-speed derailleur-equipped 6-speed Brompton, or even just the BWR wide range 3-speed hub. The left folding pedal is great, but the non-folding right pedal is less impressive, requiring replacement a few week after I purchased the bike.

I never used the stock-saddle, but it looked like it was designed for the S-type Brompton rather than the more upright posture of the M and P type bikes. It also didn’t look particularly lady-friendly. The caliper brakes are good enough, although the back brake seems to offer more power than the front, which I believe is an oddity of the Brompton in general, not just mine. I am thankful that the model I got was new enough to have the dual-pivot Brompton brake, which is reported to be a lot better than the old single-pivot model.

After a few weeks, I decided to take the plunge and fork out for the Shimano dynamo wheel before the price increase. The dynamo hub is great, it produces a reasonable output in the lights at walking speed without noticeable drag. Sadly I had to sacrifice the front dynamo light on the Yuba due to budgetary constraints, but with a little hammer adjustment, the Lyt can be used with the Brompton without interfering with the luggage system.

Overall I would recommend the Brompton to anyone. If you only wish to own a single bike, this could be it. It is remarkably versatile, being able to carry a decent load in a wide variety of high quality proprietary luggage options, cover longer distances well, offering a comfortable riding position (although it is no roadster), reliable hub gearing and on top of all that if folds into a neat package, opening up new opportunities to cycle when travelling by bus, rail or air.

  1. Hi – just came across your blog. 🙂 Congrats on getting a Brompton recently and glad you are enjoying it. I got mine last summer and have enjoyed it too. 🙂 It's an improvement over the Bike Friday Tikit I had. As you said, it's helpful that the Brompton stays folded vs. coming undone (unless you don't lower the seat all the way…which sort of "locks in" the fold). I agree re the rear brake being more powerful. I like how I can fold and cover the bike and bring it on the subway here in Washington, DC, and on Megabus, etc. Almost everytime I go somewhere, someone asks about my Brompton! 🙂 🙂
