It is possible to have the gearing on your Brompton lowered and, for 3- and 6-speed models, raised; see the full range of gearing options available. We recommend that you discuss your requirements with your Brompton dealer before specifying amended gearing; a small charge is applied for all non-standard gearing selections.

1-speed (standard ratio) £0.00, 0g *
Featuring just the elegant simplicity of our rear hub, this is the purist's choice. As with all single-speed cycling, the direct drive minimises pedalling inefficiency, though the lack of gear range may make this option unsuitable for those riding over hilly terrain and/or looking for more acceleration.

2-speed (standard ratio) £55.00, 188g *
One gear for hills & starting off, and one for cruising. Based on the unique Brompton derailleur system and an elegant new Brompton rear hub, this is the best gearing solution for lightness and portability. The direct drive, with near-perfect chain-alignment in either gear, is crisp and efficient.

3-speed (standard ratio) £55.00, 738g *
The BSR [Brompton Standard Range] is an updated version of the classic Sturmey Archer hub in an alloy shell, three well-paced gears. These are fully enclosed for reliability, and changing gear couldn’t be simpler; a popular choice for everyday cycling.

6-speed (BWR Hub standard ratio) £120.00, 920g *
The combination of the highly-efficient BWR [Brompton Wide Range] hub with our own derailleur system gives six evenly-spaced gears. Control with the two triggers is easy and, with its low transmission losses and wide range, this multi-gear system is the right choice for touring and for riding in hilly areas.
