The Brompton G Line 8-Speed SuperRoll+ is a versatile folding bike designed for riders who want to explore beyond city streets without sacrificing everyday practicality. Combining Brompton's compact folding design with larger wheels, wide tyres and reliable hub gearing, it's well suited to commuting, mixed-surface riding and everyday adventures.

The hand-brazed steel main frame and steel rear frame provide a durable foundation for regular riding. Brompton has developed the G Line around a geometry designed to offer confident handling on varied surfaces, while retaining the compact folding design that makes its bikes so practical. The bike can be folded into a secure package in under 20 seconds once familiar, making it easier to take on trains, transport in a car or store in smaller spaces.

A rigid aluminium fork complements the steel frame, providing direct steering and a straightforward setup without the additional maintenance of suspension. Mounting bosses allow compatible accessories to be fitted, adding versatility for commuting and longer rides.

The G Line features a Shimano Alfine 8-speed internal hub drivetrain, operated by a Microshift shifter. With the gearing housed inside the rear hub, the system offers protection from dirt and road spray, making it a practical choice for year-round riding. A forged 6061 aluminium crankset with a 54T chainring and integrated chainguard helps keep the drivetrain straightforward while reducing the chance of clothing coming into contact with the chainring.

Tektro hydraulic disc brakes provide controlled stopping power in changing conditions, with 140mm rotors at the front and rear. Hydraulic braking offers consistent performance with relatively light lever effort, helping riders manage their speed on descents, loose surfaces and busy urban roads.

The G Line rolls on 20in wheels with Brompton Lightweight rims and Schwalbe G-One Allround tyres measuring 54mm wide. Their versatile tread pattern provides grip on gravel and compacted dirt while maintaining efficient rolling on tarmac. The larger wheels and wider tyres also help improve comfort and stability over uneven surfaces, making the G Line more adaptable to different routes than a conventional small-wheeled folding bike.

Brompton offers the G Line in Small, Medium and Large sizes, using a shared frame design with different stem and seatpost configurations to suit rider height. Small models feature a standard seatpost, Medium models use an extended seatpost, and Large models have a telescopic seatpost. A Brompton Superlight saddle provides a comfortable contact point, while wide quick-release platform pedals offer a supportive surface for everyday footwear and can be removed for easier storage.

One of the standout features of the SuperRoll+ configuration is its improved folded portability. The Roller Frame shifts the bike's centre of gravity when folded, helping it feel lighter and easier to manoeuvre. Four roller wheels provide a stable base, allowing the bike to be pushed, pulled or steered through railway stations, offices and other indoor spaces rather than carried.

The G Line also supports compatible racks, mudguards, luggage and bottle mounts, allowing riders to adapt it for commuting, shopping or longer adventures. There's even space to store a compatible toolkit within the frame, keeping essential tools neatly tucked away.

At a stated weight of 14.8kg, the G Line balances its durable construction and larger-wheel design with the convenience of a folding bike. Whether you're cycling to work, exploring gravel paths or combining riding with public transport, the Brompton G Line 8-Speed SuperRoll+ offers a practical combination of everyday versatility, comfort and compact storage.
