Brand-new everything. Except 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.

Ultra-light. As strong as steel.

The entirely re-engineered T Line titanium frame weighs 37% less than our original all-steel equivalent and is just as strong.

At 7.45 kg in total, the T Line is comparable to a carbon road bike. Yet, it can be comfortably ridden by a 110kg rugby player. And withstand the punishing impact of the city.

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.

Pioneering Carbon Seat Post.
The first bike in the world with a steel-armoured carbon seat post. We know because we invented it.

Ordinary carbon seat posts are stiff, strong and lightweight, but they can't stand up to the daily use of a Brompton. So, we developed a new process to reinforce the limitations of carbon with 0.3mm steel armour.

The result: a superlight seat post that can take the abrasion of the fold, 110kg load and all-weather riding.

Every detail sweated
Faster to fold, easier to carry. We studied every interaction with the folded bike and improved it.

New: self-aligning hinges, always set-to-go. A spring-loaded handlebar catch that effortlessly clicks. Larger diameter rolling wheels go with the flow—an easy-grab carbon saddle with an integrated nose handle.

Nothing folds like this Brompton, not even other Bromptons.

A seriously fun ride
Brompton ride dynamics have always made owners smile, and now they're elevated in every way.

Carbon cranks and cast Ti bottom bracket shift your power for a faster ride. Naturally, shock-absorbing titanium smooths out the road. The one-piece carbon fork and wider carbon handlebars make it stiffer and even more responsive. This is a serious machine that's seriously fun to ride.
