Brompton T Line Explore - Mid Handlebar

Brompton T Line
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.

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. 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.

Expertly engineered, the T Line Explore's lightweight frame weighs 37% less than steel equivalents, improving the gearing elements and on-road positioning.

Being able to say yes to every opportunity is made possible by the simple folding system, which means you can transition from two wheels to two feet in just 20 seconds. Also light to carry, you can move around with ease in a much better way than compared to traditional bikes.

Precision engineering means you can tackle everything that comes your way. By feeling empowered thanks to the versatile T Line Explore, a more energetic and active way of life awaits you! Brompton can provide a reliable transport method; it's up to you to find your next adventure. Whichever horizon you choose to explore, with the T Line Explore by your side, a positive experience is guaranteed.

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.
