Brompton G Line - 8 Speed - With Roller Frame

The Brompton G Line is built for riders who want a folding bike that genuinely performs — not just one that ticks the 'compact' box. The hand-brazed steel main frame and aluminium fork with mounting bosses deliver a ride quality that punches above the bike's compact dimensions. Folded, it measures just 72 × 67 × 41 cm and rolls on the integrated roller frame, so you can wheel it through a station concourse or stow it in an overhead locker without breaking a sweat.

The Shimano Alfine hub system provides 8 fully enclosed gears with a 307% range — enough to tackle a bridge ramp in the morning and cruise a bike path in the afternoon. Because everything sits inside the hub, there's no exposed derailleur to knock out of alignment and no oily chain to brush against your trousers. Hydraulic disc brakes with 140 mm rotors keep stopping distances short and consistent, whatever the weather.

Schwalbe G-One All Round tyres (54-406) add a generous contact patch for stability on worn cobbles and light off-road tracks, while the tan-wall finish matches the Forest Green paintwork neatly. Mudguards and the roller frame come fitted as standard — no extras to hunt down. The frame carries a 7-year warranty, reflecting Brompton's confidence in the hand-built construction.

Three sizes cover riders from 152 to 198 cm. Size L features a telescopic seatpost (550–700 mm) for quick height adjustment when the bike is shared. Quick-release wide-platform pedals fold away to keep the packed dimensions as small as possible.
