The key difference is weight due to their frame materials. The A & C Lines uses steel frames, the P Line is a mix of steel and titanium, while the T Line has a full titanium frame. Titanium being lighter than steel means that the P Line and T Line are lighter than the classic A & C Line Brompton.
A Line: 11.5 kg; C Line: 11.8–12.2 kg; P Line: ~10 kg; T Line: ~8 kg
Brompton are designed for mobility and can be tilted and rolled by default with their two attached wheels. For greater ease of rolling, you can install the optional "roller rack" which adds two additional wheels thereby giving you the convenience of rolling the bicycle on four wheels like a luggage. Do note however, that this roller rack adds an additional ~0.6 kg of weight to your Brompton (~0.3 kg for the P Line).
While the Mid bar, Low (a.k.a. Straight) bar, and High bar generally suit people of average height, below average, and above average height respectively, your height alone does not dictate the most suitable handlebar for you because it all depends on the ride feel you want. Each handlebar configuration differs by a steering height of a mere 2 inches (~5 cm), but this little difference can significantly alter the ride feel. It’s not always the case that a taller person should use an M or H handlebar, as is the case in this video where the taller rider is using an S bar whereas the other cyclist is riding with an M bar. The S bar gives a sportier, road bike feel whereas the M or H bar offers more upright comfort. Your style of riding, your height, your sense of adventure — all play a role in your choice of handlebar.
The classic Mid (M) handlebar.
The Brompton handlebar is fixed in height. However, it is possible to change the handlebar, subject to labour and parts cost at Brompton Junction or other authorized dealers. For safety, please do not attempt to modify the bike on your own, or with an unauthorized mechanic. Do note that self modification and unauthorized modification voids the warranty.
Bromptons are extremely durable and rusting/corrosion does not commonly occur. For two reasons:
1. Bromptons are powder coated which is harder wearing than normal paint and better protects the metal from corrosion (also gives it a more pristine finish).
2. Brompton uses chromoly steel, which is a higher grade of steel that is more resistant to rust and corrosion.
Nonetheless, all metals are not immune to rusting but with proper care, maintenance, and storage, your Brompton can last several decades if not a lifetime (read what others say here, and here). Here are some tips to prevent rusting:
1. Fix paint chips or deep scratches without delay because if metal is exposed to air and moisture it begins to rust.
2. After a rainy day, wipe down your bike with a damp cloth to clean it from acid in rainwater.
3. Store your bike in a clean and dry environment away from sunlight.

Yes, Bromptons are allowed on trains and buses in Singapore, and they even fit in a standard supermarket trolley as pictured below.
The Brompton has earned its place as, arguably the best folding bicycle for good reason. It’s incredibly easy to fold, and it folds up better than other folding bikes (smaller, smoother, easier). Brompton owners, on average, take less than fifteen seconds to fold or unfold their bicycle. Sub ten is not uncommon; whereas five seconds gets you close to setting a world record.
Based on a recreational/utility cycling cadence (the no. of revolutions your pedals make per minute as you ride) of 70 rpm, the top speed of a 3-/4-speed Brompton (A Line / C Line Utility / P Line) is about 30 km/h, and 38 km/h for the 6-speed Brompton.
It is our opinion that there are no worthwhile mods to materially reduce the weight of a Brompton. Sure, you can swap out certain accessories like the saddle or pedals to shave some grams off, but we do not recommend any aftermarket parts for weight reduction. If you need a really light bike, consider a P Line (10 kg) or a T Line (8 kg).
We advise against modifying your Brompton. Aftermarket parts may look and feel like an identical and lighter replacement, but closer examinations often reveal dimensions that deviate from original part designs, which, while minute, can affect ride feel and performance and compromise safety. The original Brompton parts are manufactured to incredibly fine tolerances that typically do not deviate more than one-tenth of a millimetre (10x more precise than most other bikes!). This hairlike manufacturing precision is the reason why a Brompton rides so smoothly, and also why a Brompton feels like a bicycle than a folding bicycle. Conversely, imprecision in aftermarket parts can negatively affect ride feel and safety. Think about it... Brompton took more than a decade to recreate a model that is 2 kg lighter than the original. Ten years is a long time for a 2-kg saving. We suppose Brompton did not want to rush into a lighter bike at the expense of quality and safety so plenty of real world stress testing must have been conducted during these years. If it were so easy to shave some weight off overnight by purchasing titanium components from a Chinese factory, we suppose Brompton would have done so a long time ago. Titanium is not novel per se, and is actually a fairly abundant metal. The reason it’s rare (and expensive) to find quality titanium parts and bikes is it’s not easy to machine titanium at scale while maintaining an extremely low manufacturing tolerance.
We advise against that too. While a seatpost is a simple metal tube, tiny variations in dimension can cause unfortunate seatpost slippage or damage the seat tube. The last thing you’d want is one that does not hold its position and slips which often happens with aftermarket parts. The original Brompton seatposts are precisely designed and manufactured to prevent that.
Bromptons are designed to go up hilly areas pretty well. When it comes to bicycle science, one important attribute that determines how easy or difficult your bike climbs a hill is the size of the crankset. The smaller the crankset, the easier it is. However a smaller crankset would mean a lower top speed. That’s the tradeoff. Conversely, a larger crankset would give you a higher top speed, but comes with more climbing difficulty. Most Bromptons by default, comes with the middle of the road crankset size, i.e. 50 teeth, that is well balanced between climbing and speeding. You can change it to 44 teeth (for even better climb), or even 54 teeth (for even higher speed).
Shifting through six speeds requires both hands. The left-hand shifter is a (-/+) shifter for the derailleur, whereas the right-hand shifter is the (1/2/3) shifter for the internal hub. Here’s a quick table on how to operate them:
| Left shifter (-/+) for derailleur | Right shifter (1/2/3) for internal hub | |
| Speed 1 | - | 1 |
| Speed 2 | + | 1 |
| Speed 3 | - | 2 |
| Speed 4 | + | 2 |
| Speed 5 | - | 3 |
| Speed 6 | + | 3 |

There is a serial number found on the back of every Brompton. To authenticate and register the bike, you will input this serial number at https://www.brompton.com/bike-registration. Upon submission, a unique 6-digit frame number, which acts as a security code, will be revealed. The same code can be found embossed on the bike. For your peace of mind, we will guide you through this authentication and registration process before purchasing it. All our products are 100% brand new and authentic, and can be registered under your name and email for international warranty upon purchase. But don’t take our word for it. Read what our buyers say.
Yes, upon registration, your Brompton purchase will be covered by a 7-year unlimited mileage warranty for the main frame components; other non-wearing parts on your bicycle (crank arms, brake calipers, mudguards, etc.) are covered by a 2-year warranty. Within the warranty period, your bike will be supported by the free issue of parts from the Brompton factory, however the Brompton distributor or dealer in town (e.g. Brompton Junction Singapore) will normally charge for the labour required to undertake warranty repairs, and for any import duty levied on the free-issued parts. Please refer to the Warranty Terms & Conditions in the user manual.
It is important to note that for warranty to be valid, the bike must not have been subject to any modification, repair or replacement other than as authorised by Brompton, and must have been serviced by an authorised Brompton Dealer (e.g. Brompton Junction Singapore).
Yes, every bicycle comes in its original box.
No, it does not. Please see a detailed answer in the next question below.
What’s in the box are: Bicycle (of course), Owner’s manual, Saddle height insert. The bicycle comes as spec’ed on the Brompton website (e.g. https://www.brompton.com/p-line), except for the Front carrier block, battery lightings, and rack. Please note that all bicycles do not come with a Front carrier block, battery lightings, and rack, unless otherwise stated on our website as these accessories are online specs and are not the standard base specs.
According to Brompton, all bicycles go through stringent quality testing procedures by its Brompton Quality team in London. After opening the box, you will have to install the saddle (seat) and in some cases, the pedals and lighting reflectors. We will be able to perform the assembly for you and give you a demonstration on the proper usage of the folding mechanism. You will then be given the opportunity to do a brisk test ride in a safe location. Do note however that the bicycle must be inspected by a qualified mechanic before first use.
Yes, because all new bicycles will go through a “bedding in” period as new components settle into your riding style. At this stage, it’s not uncommon for them to need a little adjustment to help keep everything running smoothly. Brompton recommends having the bicycle checked by a qualified mechanic after the first 160 km (approx 8 hours at normal cycling speed) or 1-month (whichever comes sooner) as some items take time to bed in and may need adjusting to avoid damage.
