Brompton Electric G Line Folding Bike - 4-Speed
The Brompton G Line is designed for longer and further travel. The bike features larger 20 inch wheels, unlike the other bikes in the Brompton range which are 16 inch. The larger wheels means the fold is not as compact but the bike still folds in the same unique way, making it the smallest folding 20 inch bike.
Fitted with wide, grippy tyres, disc brakes and a bottle cage mount, the bike is ideal for riders who want to go further afield or cross through one on their way to work or at the weekend. The bike is available in small, medium and large sizes with geometry that is adjusted for off-road riding, thanks to a different shape of stem. The stem also features mounts for a bottle cage, as does the front fork. There are new grips with support across the palms for longer rides.
You can run a rack, mudguards, and bags, add water bottles, and even store your toolkit inside the frame. And with the original Brompton fold, the ever-ready G Line transforms into a compact, locked package in under 20 seconds. Goes on trains. Travels in car boots. Stores in small spaces (including one-person tents).In a world full of possibilities, G Line is your one-bike route to everywhere.
Rear Wheel Battery Power
The G Line Electric is powered by a 345Wh battery which has a 5 hour charge time. The battery powers a rear wheel hub with the cabling fed internally through the frame to limited catching on foilage. The battery has a 30-60km range 5-hour full charge and connects to a Brompton app. The new position of the battery provides greater stability and balance to the bike, providing better handling in off road scenarios.
