The Brompton T Line 4-Speed Mid Bar is an exceptionally lightweight titanium folding bike created for riders who want the ultimate combination of performance, portability and everyday practicality. Weighing from just 7.95kg, the T Line takes the familiar Brompton folding bike experience and re-engineers it around titanium and carbon fibre to create a faster, lighter and more dynamic ride.
At the heart of the T Line is its Grade 9 titanium main frame. Titanium provides an exceptional strength-to-weight ratio while being naturally resistant to corrosion, allowing Brompton to significantly reduce weight without sacrificing the durability required for everyday riding. Each titanium frameset is expertly TIG welded at Brompton's specialist facility in Sheffield.
The Mid handlebar provides a comfortable and versatile riding position, making this version an excellent choice for everyday city riding, commuting and longer urban journeys. It offers a more upright position than the Low handlebar while maintaining the T Line's responsive and agile character.
Weight-saving engineering extends throughout the bike. A one-piece carbon fork and steerer help reduce weight while absorbing road vibrations, while the Superlight carbon crankset combines a hollow BB30 axle, integrated spider and 56T chainring. Superlight components including the saddle, seatpost, pedals and grips further contribute to the bike's remarkably low overall weight.
Brompton's compact 4-speed drivetrain has been specifically engineered to fit neatly inside the fold. Offering a 163% gear range through 11, 13, 15 and 18-tooth sprockets, it provides useful gearing for fast urban riding while maintaining the lightweight simplicity of the T Line.
Schwalbe ONE tyres with Addix Race rubber and V-Guard puncture protection provide a fast, responsive connection to the road. Lightweight wheels with double-butted spokes and Tubolito S-Tubo tubes further reduce rotating weight and contribute to the bike's quick and agile ride feel.
Despite its focus on minimum weight, the T Line remains a practical Brompton. Mudguards are included for year-round riding, while the large-diameter front carrier block adaptor allows you to use compatible Brompton front luggage without carrying the load on your back.
The folding system transforms the bike into a compact package measuring just 25.4" high, 23.6" wide and 12.6" deep. This makes it easy to take onto trains, store at work, keep at home or carry when cycling isn't practical.
Attention to detail extends to every interaction with the bike. Machined aluminium self-aligning hinge clamps make folding straightforward, while the Superlight CNC aluminium pedal set includes a quick-release left pedal to help maintain the compact folded package.
Finished in Blasted Titanium, the T Line celebrates the distinctive appearance of its premium frame material while delivering the corrosion resistance and strength that make titanium particularly well suited to a high-performance folding bike.

For riders looking for maximum portability without giving up ride quality, the Brompton T Line 4-Speed Mid Bar combines an ultralight 7.95kg starting weight, titanium construction, carbon components and Brompton's compact fold in one exceptionally refined city bike.
