Experience the freedom a Brompton folding bike brings you. This clever bike folds up to a third of its size, and it is suitable to take on all forms of transport – perfect for mixed commutes on trains, popping in the car boot for a weekend adventure, hailing a taxi at odd hours or when the weather turns.
When folded, a Brompton stays locked together, transforming into an extremely compact package just a little wider than its wheels. All in 15 seconds!
(Bk) Bikes have black components; primarily the handlebars, seatpost and crankset. Brompton has largely stopped referencing bikes by model year, but you may find the (Bk) referenced as MY23 as opposed to MY22 which features silver components.
