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.
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.

T Line Urban - 4 Speed
Feel inspired by titanium's lightweight, bright, and mesmerizing qualities with the T Line Urban from Brompton. With this sleek bike, you can experience the city in an immersive way. By choosing this lightweight yet powerful model, you can keep focusing on your surroundings as your bike does all the work for you. From noticing the change in a breeze that signifies the entrance to a city to the unique sounds you only hear when riding the T Line Urban lets you embrace urban life completely.
To get you around the city, this bike includes 4-speed gears, which improve control and agility. Expertly engineered, this 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. Because of the shape of the handlebar, the front reflector needs to be secured to the diagonal part of the bars by the shifter.
Precision engineering means you can tackle everything that comes your way. By feeling empowered thanks to the versatile T Line Urban, 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 Urban by your side, a positive experience is guaranteed.
