Brompton gears explained in great detail! Anybody who has ever owned or considered buying a Brompton has had questions concerning the use of the gears.
Unlike a traditional geared bicycle, the Brompton can contain a 2-speed derailleur plus a 3-speed internal gear hub.
The first time I test rode a Brompton folding bike, it was a 6-speed.
This tiny hand brazed bicycle had a gear selector on both the right and left handlebars.
On the left side was the selector that controlled the 2-speed derailleur. On the right side was the selector that controlled the 3-speed internal geared hub.
At first, this setup can be very confusing. Especially if you’re use to regular derailleurs from companies such as Shimano or SRAM.
As Brilliant Bikes explains perfectly in the video, it definitely takes a little getting use to. But with a little practice, anybody can get use to this gear setup in no time.
Brompton gears offers many choices depending upon preference and riding terrain
At first, picking the right gears for your Brompton may seem confusing. But after learning more about them you’ll not only know which ones you need or prefer, you’ll also be a pro at using them.
Brompton offers 4 different gearing options, with each being able to be lowered or raised to suit your riding style or terrain.
1-Speed: Designed for the purist that likes their bikes light and simple without clutter, perfect for flat city riding.
2-Speed: This is the model I chose because of it’s light weight and flexibility. The 2-speed uses the unique brompton derailleur system. It provides near perfect chain-alignment while still having great flexibility and portability. There’s one gear for starting off and hills, and one for cruising.
3-Speed: A popular choice for everyday riding, the BSR (Brompton Standard Range) hub is an updated version of the classic Sturmey Archer three-speed hub. Fully enclosed in an aluminum allow shell, it is reliable and easy to use.
6-Speed: Considered the ultimate all-rounder, the 6-speed combines the BWR [Brompton Wide Range] hub with the derailleur system. This gives it six evenly spaced gears with low transmission losses and wide range. These gears makes it the perfect choice for touring and hilly areas.
