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 16.4 lbs in total, the T Line is comparable to a carbon road bike. Yet, it can be comfortably ridden by a 242 lbs 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, 242 lbs 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.
