Brompton folding bikes
Brompton folding bikes can be custom ordered but typically take 4 weeks to arrive in the U.S. from London. However, many Brompton stocking retailers have pre-configured bikes on hand for immediate delivery.
The nomenclature to denote individual Brompton models is a 3 character name. The first character is the handlebar type, of which there are 4 types M, H, S, P; each provides for a different riding position. The second character is the speeds, which is either 1, 2, 3 or 6. The last character denotes whether it has a rack with fenders (R) or no rack with fenders (L) or no rack, no fenders (E). So for example a Brompton M6R has an M-type handlebar, 6-speeds, and rear rack and fenders. Bicycles that have the titanium rear triangle and front fork option have an "X" appended to the model name, for example M6R-X. All Brompton folding bicycles are fitted with 16" wheels and have rear suspension provided by a polyurethane block between the main and rear frame.
Bromptons range in price from $1337.00 up to $3146.00. For example, at the low-end would be a M1E with an MSRP of $1337.00 and would weigh in at 23lbs. At the high-end would be an M6R-X featuring a titanium rear triangle and front fork and a Son Hub Dynamo lighting kit and would weigh in at 26.1lbs. There is no price difference for handlebar types so you can choose one that fits your preferred riding position (see below). You can get your Brompton in a myriad of color combinations so you are sure to find one that appeals to you. Accessorizing your Brompton with an upgraded saddle, raw lacquer paint, and luggage options adds to the price. The animation below shows the difference between the low-end M1E and the high-end M6R-X.
The animation below illustrates the different Brompton handlebar types. The M-type is the original classic handlebar. The H-type is just a higher version of the M-type, it's meant for taller riders or people who like a more upright riding position. The S-type is a lower positioned straight bar designed for a more sporty riding position, it's also the lightest handlebar version. The P-type is the touring handlebar that allows for two riding positions; a lower one for a longer distance aerodynamic riding position and a higher one for more control.
