Brompton P Line 4 Speed 2025 Low Handlebar Folding Bike - Bolt Blue Lacquer

The Brompton P Line is a British-made steel folding bike designed for commuting, train travel, and city riding. This particular example is finished in Bolt Blue Lacquer, a colour that catches the light beautifully and has been maintained in excellent condition since purchase in June 2025. The bike has seen minimal use and is ready to ride immediately without any work needed.

The 4-speed model uses a 54T chainring paired with Brompton's derailleur gears, giving you enough ratios for urban riding without the complexity of more speeds. The flat bar setup keeps the riding position practical for city cycling, and the 16-inch wheels are typical Brompton spec—they make the fold compact and keep the bike nimble in traffic. The self-aligning hinge clamps are an upgrade that makes the fold more reliable and consistent with repeated use.

What makes this build stand out is the component specification. The Superlight wheels and pedals keep rotational weight down, which matters when you're folding and unfolding regularly or carrying the bike on the train. The Continental Urban Contact tyres are fitted with Presta inner tubes, and both the chain and brake pads are in near-new condition. Mudguards and reflectors are already fitted, so you're covered for all-weather commuting straight away. The working Brompton bell is included, along with the triangle frame bag and top tube storage bag—practical additions for carrying keys, phone, wallet, and tools without needing a rucksack.

At its core, the Brompton folds into a genuinely compact package that fits under a desk or into train luggage racks, and the mechanism here works perfectly. The bike has been stored carefully and presents beautifully, representing a significant saving against the cost of an equivalent new Brompton with this accessories package included.
