Titanium is ultra strong and ultra light. It’s the world’s number one naturally occurring metal for strength-to-weight ratio.
Being naturally corrosion resistant means high shine and zero rust in all conditions.
More gears. More range. Even more possibilities. 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.
Invention, innovation and imagination have been the driving principles at Brompton since the beginning.
Over five decades of ambitious design have led us to the T Line. Engineered with a lightness unlike anything you’ve experienced – the T Line has a re-engineered all-titanium frame and super responsive carbon components. At just 7.45kg, the lightest Brompton ever made delivers unmatched performance and practicality.
Add to this the smoother, faster folding mechanisms and experience freedom in the city like never before. The best of the Brompton experience, amplified with the power of titanium.
The lightest Brompton ever made
Super responsive carbon components
Reengineered titanium frame provides a dynamic and agile ride
Faster to fold and easier to carry
Accelerate smoother and faster with a superlight crankset
This is the T Line in its purest form. A single-speed machine, perfect for riders who value simplicity and efficiency. With no need to shift gears, the T Line One offers a breezy, low-maintenance riding experience.
The single-speed setup provides a smooth and consistent ride in flat cities. Ideal for minimalist, flat-terrain commuting.
The T Line 4-Speed has 4 gears – using a tiny derailleur that weighs only 60g – and mudguards. This makes it heavier than T Line One, but not by much.
The T Line Urban 4-Speed offers unmatched portability and durability. The 4-speed drivetrain is optimized for city performance, which ensures smooth gear transitions whether you’re cruising, accelerating or climbing hills.
The perfect city bike: the T Line 4-Speed is easy to carry onto public transport thanks to its compact and lightweight design. Ideal for daily commutes or weekend rides – this model combines efficiency, strength and style for the ultimate urban mobility solution.
The T Line 12-Speed has a unique gear system that provides more range and more possibilities. This means it's easier to ride up and down hills. Experience the lowest gear ever and the highest gear ever (with lots of small steps in-between). Ensure a comfortable ride for touring, exploring, commuting and beyond.
Enjoy the range of a road bike, hybrid bike, commuter bike or city bike, all with the convenience of the compact Brompton package.
The Brompton P Line is designed for lightweight performance. Weighing as little as 9.7kg, the P Line is handcrafted from steel and titanium. The T Line is the lightest Brompton ever made - starting at 7.4kg, built in titanium with custom carbon components.
Designed to pack a punch in the city, the Brompton P Line has a titanium rear frame and fork – refined geometry and an exceptional ride feel. It’s easy to carry and manoeuvre on the go. With Advance Roller Wheels, Continental Contact Urban Tyres and a superlight gear system, the P Line excels on the road. Expect greater efficiency, sharper handling and fast acceleration.
Built in pursuit of lightweight performance, the Brompton T Line is lighter, faster and even more fun. The product of three years of research and development, T Line required new construction techniques, the design of over 150 components in titanium and a new factory dedicated to making the titanium parts.
Expect super responsive carbon components and faster folding mechanisms, alongside Schwalbe One Tyres, superlight carbon crankset and a tig-welded titanium frame. T Line delivers unmatched performance and practicality – for a dynamic and agile ride every time.
The smaller 16” wheels on a folding bike make it easier to get going, so you can get to your destination faster. This is ideal for the stop-start riding style typically encountered within a city.
With a speedy 20-second fold, the Brompton folding bikes are also perfect for multi-modal travel. Hop on and off public transport, fold and unfold your bike in less time than it takes to order a taxi.
All Brompton T Line frames start their life as a set of tubes in our specialist TIG welding factory in Sheffield, 300km (186 miles) north of our London factory. We built this dedicated space as titanium requires different skills, machinery and process than steel. The city of Sheffield has a rich history and legacy of expertise and metalworking.
The TIG Welding process requires a high level of skill and coordination. Even the most experienced welders need time and intense focus. Each welder has a signature style – making every weld unique.
As well as being ultra-light, titanium is super strong. Being naturally corrosion resistant means high shine and zero rust in all conditions. The result? A robust and reliable T Line frame.
Looking to enhance your ride? We have a wide range of parts and accessories, designed and made with the same ethos as the bike. There’s the front carrier block, which securely attaches to the front of your Brompton T Line to provide a sturdy attachment point for carrying items – or the superlight carbon low handlebar made of carbon fibre.
Our Be Seen Lights enhance your visibility on the road with a 26-lumen front white LED light and an 11-lumen rear red LED light. For an efficient solution to transporting your bike when folded away, the Complete Rear Rack Set has been designed to clip onto the back of your bike with ease. Fold your Brompton down in less than 20 seconds, roll it along and make it in time for your next train.
