Brompton Electric C Line 4 Speed Mid Folding Bike - 2023 - Ocean Blue

The Brompton Electric C Line is a British-made folding bike that combines the practicality of Brompton's famous compact design with electric assistance for city riding. Built in London from heat-treated steel with precision hand-brazed and auto-brazed joints, this is a proper folding bike engineered to go anywhere, then fold away to nothing. The C Line sits at the heart of Brompton's range because it offers the most customisation options, and this 2023 model in ocean blue comes equipped with four gears and a 250W motor developed with Williams Advanced Engineering.

The steel frame and reinforced fork are built to handle the extra demands of electric assistance, whilst the compact motor and fine-tuned sensor in the bottom bracket deliver smooth, proportional help without feeling jerky or over-eager. Brompton's Smart Pedal Assist knows when to engage and when to ease off, learning your cadence and throttling power delivery intelligently. You can breeze through city streets at speeds up to 25 km/h (15 mph), and the 300Wh 36V battery gives a realistic range of 30 to 70 kilometres depending on assist level and terrain. The battery detaches like a phone power pack, charging in four hours with the included 2A charger, and features a 5V USB port so you can top up other devices on the move.

The drivetrain uses Brompton's patent-pending 4-speed derailleur with trigger shifters, paired to a 54-tooth chainring with integrated chainguard. The rear wheel is a single-wall alloy rim laced to the 4-speed hub, shod with 349 x 35C Schwalbe Marathon Racer tyres that resist punctures and feature reflective sidewalls for visibility. Mudguards with rubberised flaps keep spray off your legs and clothes during wet weather. Braking is handled by Brompton's dual caliper rim brakes with integrated levers, proven design rather than cutting-edge but reliable and easy to maintain on the road.

The saddle is Brompton's own design with an integrated carry handle and mounts for a rear light and saddle bag, whilst the chromoly steel seatpost accommodates riders with an inside leg measurement up to 84 centimetres (33 inches). The handlebar and grips are aluminium and rubber respectively, built to handle daily commuting without fuss. Lighting comes from a 40 Lux Busch & Müller AVY LED front lamp and rear lamp both powered by the main battery, so you don't need to think about separate lights.

The fold is compact enough to carry onto buses and trains, or to keep in a small flat or office without taking up much space. It's not weightless like an ultra-light road bike, but it's manageable, and electric assistance means hills and loaded journeys feel easier than on a non-motorised Brompton. The four-speed gearing handles London's mix of flat stretches and moderate inclines well, shifting smoothly via the trigger mechanism without fuss. This bike is aimed at anyone who cycles regularly but also uses public transport, or who needs reliable electric-assisted commuting in an urban setting without the footprint of a full-size e-bike.
