How 12 speed works

Just like our bike, Brompton’s 12-speed gear system is unique– we’ve expertly engineered a solution that gives you more gears and more range while still fitting into our compact solution to life on two wheels.

Using the gears

Our 12-speed gear system gives you all the range of – and sometimes even more than a road, hybrid, commuter or city bike, all with the convenience of the compact Brompton package: lightweight, portable, folding.

Superlight, compact 12 gear system built for the city.

At Brompton, we don’t believe that more always means more. That’s why we offer you a choice of gears. For flatter cities, short rides and even infrequent use, less and simpler is often better. But other times, you might want – or need – more. That’s where our all-new 12-speed comes in. Just like our bike, Brompton’s 12-speed gear system is unique.

Brompton T Line folded

Brand-new everything. Except for the fold.

The all-new ultra-light titanium frame. Over 150 specially developed weight-saving components. Three years of obsessive material choices and rigorous testing. Everything brand-new except the fold. Andrew Ritchie, our founder, obsessed over that 40 years ago. Never bettered, just refined, it's the original and still the best.
Brompton T Line folded

Compact drivetrain, designed ground-up.

Nothing rides like it—the entirely new* drivetrain. Designed ground-up to sit inside the fold, to be light as possible and for optimal city performance. The carbon crankset gives greater power transfer. The 60-gram derailleur delivers smooth shifting in a small package. The new gear-ratio, tested from Amsterdam to San Francisco, perfected for city roads. *patent-pending
