The Brompton G Line is an alternative format to the classic Brompton bike model with its well deserved reputation as the best folding bike in the world. We think the Brompton G Line will be a real hit in Australian conditions; from rough roads to rail trails, it can handle it all!

Expertly engineered to go where others can’t. G Line is the first ever Brompton with the ride feel of a full-size bike. Brand-new geometry, 20” wheels, game-changing comfort and capability. All holistically designed around the fold that made Brompton famous. It's your one-bike solution to the city and beyond.

• 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.
• 8 speed Internal gear hub: gives a wide range of gears and the ability to shift gears while stationary. Gears are sealed within the hub for low maintenance and durability.
