Brompton T Line Titanium Carbon 12 Speed Folding Bike

This is a 2025 Brompton T Line Titanium folding bike in 12-speed, which makes it one of the rarest configurations Brompton produces. The titanium frame is the pinnacle of what Brompton builds, paired with carbon fibre components throughout—the seatpost, forks, handlebars and crank are all carbon, which keeps the overall weight remarkably low without compromising stiffness. The bike has covered limited miles and remains in very good condition, with just a few minor scuffs that come naturally from use rather than any structural issues.

The 12-speed hub gear setup runs smoothly and is dialled in well, giving you genuine range without the maintenance demands of a derailleur system. The 16-inch wheels fold compactly while still rolling efficiently for a small-wheeled bike, and the side-pull caliper brakes offer straightforward stopping power. What you get day to day is a lightweight, quick-handling folding bike that genuinely performs—this isn't a bike that makes compromises just to fold, but rather one that happens to fold while delivering the efficiency you'd expect from premium components and titanium engineering.

It comes equipped with a superlight rear rack, mudguards, a bell and lights, so it's ready to use as delivered. The original Brompton box is available if you need to ship it, though collection from Borehamwood can be arranged. This is the type of bike that deserves to be ridden rather than sat in a garage, which is why it's being passed on to someone who'll actually use it. The original retail price was £4969.
