Brompton T Line - 12-Speed - Mid Bar - Standard Seatpost - 16" Folding Bike - 2026 - Blasted Ti

T LINE - The lightest folding bike of Brompton.

At Brompton, they don’t believe that more always means more. That’s why they 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 the all-new 12-speed comes in. Just like a Brompton bike, Brompton’s 12-speed gear system is unique. They have expertly engineered a solution that gives you more gears and more range while still fitting into a compact solution to life on two wheels. 

Expertly engineered, the T Line - 12-speed's lightweight frame weighs 37% less than steel equivalents, improving the gearing elements and on-road positioning.

Precision engineering means you can tackle everything that comes your way. By feeling empowered thanks to the versatile T Line - 12-speed, 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 - 12-speed by your side, a positive experience is guaranteed.

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, the founder of Brompton, obsessed over that 40 years ago. Never bettered, just refined, it's the original and still the best.

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
