Brompton T Line 12 Speed Mid Bar Brand New

This is a brand new, unregistered Brompton T Line 12 speed folding bike, bought directly from Brompton in December 2025 and never ridden. The T Line uses a mix of titanium and carbon fibre to keep weight down without sacrificing the rigidity you need for daily riding, and the frame is the classic British steel construction Brompton is known for, built around a 16-inch wheel setup and a lateral fold that tucks the bike into a genuinely compact package.

The 12-speed hub gear setup gives you decent range for mixed urban and suburban riding, controlled via Brompton's straightforward gear change mechanism. Stopping power comes from side-pull caliper brakes, which are simple, reliable, and easy to maintain. The bike comes with a seat extension fitted, so it's already set up to suit a taller rider comfortably, which saves the hassle of adjusting or sourcing the right height post.

What you're getting alongside the bike itself makes this a complete package. It comes boxed with an integrated Brompton toolkit—genuinely useful for roadside adjustments—and a waterproof Brompton briefcase, which together are worth around £250 if bought separately. The briefcase is one of those accessories that transforms how you actually use a folding bike, keeping your bag and the bike together as one unit when you fold it up on the train or bus.

This is the bike ready to go, with nothing to hunt down or sort out before your first commute.
