Brompton T Line 12 Speed – The Ultimate Lightweight Folding Bike

The Brompton T Line is the lightest and most advanced folding bike in the Brompton range. Built with an ultra-light titanium frame and premium components, it’s designed for riders who want the best in performance, portability and everyday usability.

Finished with a durable Cerakote ceramic coating, the T Line Ceratech offers increased resistance to wear while maintaining its clean, premium look. The all-new 12-speed drivetrain provides a wider gear range than ever before, making it just as capable on hills and longer rides as it is in the city.

Despite its high-performance design, it keeps the classic Brompton fold, transforming into a compact package in around 20 seconds—easy to carry, store and take anywhere. Lightweight, refined and incredibly versatile, this is a folding bike built without compromise.

Precision, power and portability.

Ultra-light titanium frame & components

Ceratech ceramic finish

Ceratech protects, but it also embellishes. The matt metallic colour is deep, yet you can still see the beauty of the hand-welded titanium frame. When you lift your bike, it feels wonderful to touch, like velvet metal.
