Brompton Electric G Line with SuperRoll+ - e-Motiq system - 4-speed

This is a used Brompton Electric G Line with SuperRoll+ in forest green, size large. The bike has covered 121 miles and the battery has been through three charging cycles. There are some scuffs and scratches on the frame and carrier rack, consistent with normal use. This is a British-made steel folding bike designed for everyday urban riding with electric assistance, combining Brompton's compact fold with motor-driven propulsion to extend range and reduce effort on urban commutes.

The frame uses hand-brazed steel for the main structure with a steel rear frame and aluminium fork fitted with mounting bosses. The folded dimensions are 72cm deep, 67cm high, and 41cm wide, making it compact enough to carry onto trains or store in small spaces. With the battery fitted, the bike weighs 19.5kg; without it, 15.7kg. The large size features a telescopic seatpost with a standard wide saddle, ergonomic grips, and self-aligning hinge clamps that make the fold straightforward and the frame rigid when unfolded. G Line aluminium seatclamps and wide platform quick-release pedals complete the setup for easy adjustment and stowage.

The drivetrain is a 4-speed Brompton system with a 50-tooth chainset and sprockets ranging from 11 to 18 teeth, giving a 163 percent gear range. Microshift shifters control the gears, with a Brompton headset keeping the front end stable. Tektro hydraulic disc brakes with 140mm front and 160mm rear rotors provide reliable stopping power in all conditions. Both wheels are 20 inches and fitted with Schwalbe G-One All Round tyres in 54-406 size with tan walls. The bike runs tubeless with Hope valves and Peaty's sealant, which reduces puncture risk and improves ride quality on urban streets.

The e-Motiq system includes a 345-watt-hour battery with an LED display that charges fully in four hours using the included 2-amp charger. Range sits between 20 and 45 miles depending on terrain, assistance level, and riding style. The bike comes with integrated AVY lighting, full mudguards to keep spray off your clothes, and a front carrier block adaptor that accepts standard Brompton luggage. The essentials battery bag provides 1.5 litres of storage, and a Brompton bell is fitted. The rear rack is included. Both iOS and Android apps are available for monitoring the Brompton Electric system and adjusting assistance modes. This bike suits commuters who want motor assistance on the school run or longer journeys but need a bicycle compact enough to fold and carry when mixing cycling with public transport or working from different locations.
