Brompton bike C-line 12-speed 2025 mid bar In bumblebee yellow

The Brompton C-Line 12-speed in Bumblebee Yellow is a British-made steel folding bike built for commuting, train travel, and city riding. This particular model uses Brompton's proven lateral fold system, which compresses the bike down to a genuinely compact package that fits under train seats, into car boots, or stored upright in a flat corner. The steel frame is engineered for long-term durability, and the fold mechanism itself has been refined over decades—it's quick to operate once you've done it a few times, and the bike collapses without needing to remove pedals or adjust anything.

The 12-speed Sturmey Archer hub gear gives you genuine climbing range without the maintenance demands of a derailleur system. You get enough ratios to handle hills comfortably while still spinning easily on flatter sections, and the sealed hub means the gearing stays reliable through wet winters and neglect. The 16-inch wheels contribute to the tight fold and make the bike responsive in traffic, though they do demand slightly more cadence to maintain speed on longer stretches compared to larger wheels. Stopping power comes from side-pull calliper brakes, which work adequately for urban speeds and are straightforward to service.

Day to day, the C-Line rides with an upright position that keeps your weight centred over the bike, making it stable at low speeds and good for visibility in traffic. The integrated mudguards keep spray off your commute clothes, and it's set up to work well in the stop-start rhythm of city cycling. This is Bumblebee Yellow—a discontinued colour that no longer appears in Brompton's current range, making it a rare find. The bike is in excellent condition, serviced and ready to ride, fitted with Schwalbe Racer tyres, and comes with spares including a new front mudguard flap, new grips, and Bumblebee Yellow paint for touch-ups. It's registered on BikeRegister.com and Brompton Bike Register, with a seven-year transferable warranty included.

This bike suits anyone who commutes by mixing cycling with rail travel, works in an office without bike parking, or lives in a flat where space is tight. The 12-speed gearing makes it genuinely rideable for longer weekend journeys as well, rather than just short urban hops. If you're after a practical, durable folding bike with character, this Brompton does the job without compromise.
