Brompton G Line With Rack 2025 Folding Bike in Forest Green

Season:2025

Brand:Brompton

Code:75189FORESTGEEN

The Brompton G Line is a different kind of folding bike, and if you've been looking at the G Line Brompton wondering whether it actually lives up to the hype, the short answer is yes.

Most folding bikes ask you to accept a trade-off. You get portability, but you give up ride quality, or capability, or both. The Brompton G Line was built to close that gap. It's the first Brompton with the ride feel of a full-size bike, and it shows the moment you get moving.

The 20" wheels play a big part in that, large enough to roll confidently over rough ground, pot holes and gravel, yet compact enough to disappear neatly into the fold.

And it does genuinely fold, in under 20 seconds, into a locked, compact package that goes on trains, fits in car boots, and stores in spaces you wouldn't expect. One-person tents included, apparently.

This particular model comes with a rack, which makes it genuinely practical for commuting, touring light, or just carrying the things you actually need day to day. You can add mudguards, bags, and water bottles, and there's even space inside the frame to store a toolkit. As a one-bike solution, it's hard to argue with.

20" wheels
Solidly built and fitted with custom puncture-resistant tyres, the G Line's wheelset is one of the things that separates it from every other Brompton Folding Bike that came before it. More confidence on surface changes, more stability at speed.

Hydraulic disc brakes
The first Brompton ever to come with disc brakes. Reliable stopping power in all weather conditions, which matters a great deal if you're commuting through a British winter or heading off-road.

Wide platform pedals
The grippiest pedal set Brompton has made. The left pedal releases with a quick squeeze and pull when folding, keeping the packed size as small as possible.

Wide handlebars
Custom-made for the G Line, giving you real leverage on climbs and rougher ground, along with a comfortable, stable position on longer rides.

Ergonomic grips
Every contact point between rider and bike has been thought through carefully. On a bike you might ride for hours at a stretch, that's not a small detail.

If you're looking at the Brompton G Line for sale and trying to decide whether it suits your life, the honest answer is that it suits most lives. Commuters, tourers, weekend explorers, anyone who wants one bike that handles everything without needing a garage to store it.
