Product Details

Brompton G Line 8-speed Folding Bike

Brompton designed the G Line 8-speed Folding Bike to combine the comfort and geometry of a full-size bike with the portability of a Brompton fold. Its all-new frame, 20” wheels, wide handlebars, and tyres deliver a balanced, stable ride that feels like a mountain bike, giving you confidence on rough singletrack, rain-soaked cobbles, or smooth city roads.

Expertly engineered for practical urban and leisure use

The G Line isn’t just capable on the road; it’s built for everyday life. With mounting points for a rack, mudguards, and bags, plus space for water bottles and even a toolkit inside the frame, it adapts perfectly to commuting, shopping, or multi-day trips. Its 8-speed gearing system gives you a versatile range, letting you tackle hills, flats, and stop-start traffic with ease, making it the do-it-all bike for both city and leisure cyclists.

Compact fold for effortless travel and storage

Despite its rugged capabilities, the G Line retains Brompton’s signature fold, transforming into a compact, locked package in under 20 seconds. It fits on trains, into car boots, small apartments, and even one-person tents, giving you unmatched flexibility. Available in small, medium, and large sizes, each frame is optimised for height and riding comfort, so whether you’re commuting to work, exploring new cities, or heading off-road, the Brompton G Line 8-speed Folding Bike makes every journey easier, more enjoyable, and ready for any adventure.
