Brompton G Line 8-speed Folding City Bike with Roller Frame

We created G Line to be the best one-bike solution for the city and beyond, and then we made it a Brompton. The frame geometry is comparable to a full size bike, yet it transforms into a compact package that stores and travels easily. So you can go anywhere.

Rigorously tested over 250,000 km, first to meet industry standards, then to meet ours, G Line goes where others can’t. Now, you can confidently tackle everything from dusty singletrack to rain-soaked cobbles. This bike does it all with ease.

Features

• Nothing feels like G Line – the entirely new frame, all-new 20” wheels, our widest ever handlebars and tyres. Everything is thoughtfully engineered to give the balanced feel of a mountain bike and all-day comfort that’s nothing short of joyous. You’ll feel the difference on every ride.
• The most versatile bike in the world: Expertly engineered to go where others can’t. G Line is the first ever Brompton with the ride feel of a full-size bike.
• 20” wheels: Big enough for any adventure yet compact enough to fit inside the fold. The G Line’s solidly built 20” wheelset comes equipped with custom-made puncture-resistant tyres.
• Hydraulic disc brakes: Super dependable stopping power. The first ever Brompton to come equipped with disc brakes for all terrain, all-weather riding.
• Wide platform pedals: The grippiest, most comfortable Brompton pedal set. The left hand pedal can be released with a quick squeeze and pull to make your folded bike even more compact.
• Wide handlebars: Stay in control. With the custom made handlebars, G Line gives you exceptional stability – from leverage on uphills and rough ground to comfort on longer rides.
• Ergonomic grips: Every touchpoint between you and the bike is designed with comfort and control in mind.
