Titanium 2025 Brompton T Line M Bar 4-Speed L Brand New

This is a brand new, unregistered Brompton T Line M Bar 4-Speed L folding bike, fresh from the box and ready to ride. It's a 2025 model built to Brompton's established formula: a compact, portable bike designed for urban commuting and everyday use. The warranty can be registered on Brompton's website once you have the bike in hand.

The frame is titanium, which gives the bike a lightweight, durable platform without the weight penalties of steel. It uses Brompton's lateral fold mechanism, compressing down to a size small enough to carry onto trains or store in tight spaces. The 16-inch wheels are standard for the Brompton range, making the bike quick through traffic and contributing to the compact fold, though they do mean you're working a bit harder on longer flat runs compared to larger wheel sizes.

Gearing is handled by a 4-speed hub gear with thumb shifter operation, which keeps the drivetrain simple and low-maintenance. This is enough for most urban riding with gentle hills, though steeper gradients will feel slower than higher-geared alternatives. The M Bar handlebars give an upright, practical riding position suited to city cycling, where visibility and control matter more than outright speed. Braking comes from side-pull caliper brakes, which are responsive and reliable in dry conditions.

This bike works well for commuters who need to combine cycling with public transport, or anyone living in a small flat or office where storage space is at a premium. The titanium build and Brompton heritage mean it's built to last, and the fold means it goes with you rather than requiring secure outdoor parking or dedicated indoor space.
