Hand-brazed construction, combined with selected automated brazed joints, provides a strong and durable frame designed for regular use.Built using Brompton's established folding frame design, the Electric C Line combines the familiar handling of a traditional Brompton with the convenience of electric assistance.Compact Folding DesignThe Brompton Electric C Line retains the compact folding mechanism that makes Brompton bikes particularly practical for commuting and travelling.The frame folds into a small package that can be carried onto public transport, stored at home or kept in an office.This makes it suitable for journeys that combine cycling with trains, buses or walking, giving riders more flexibility when planning their daily commute.SuperRoll+ SystemThe SuperRoll+ system makes moving the Brompton easier when folded, reducing the need to carry the bike through stations, offices and other indoor spaces.The Roller Frame shifts the bike's centre of gravity and incorporates four wheels at the base, creating a more stable platform for rolling.Two rolling configurations provide additional flexibility. Shopper Mode uses the raised seatpost to help manoeuvre the folded bike, while Suitcase Mode uses the lowered seatpost for a more compact arrangement.The folding mechanism keeps the bike secured together while rolling, allowing riders to push, pull and steer it through busy environments.Brompton e-Motiq Rear Hub MotorThe Brompton e-Motiq system features a custom-designed rear hub motor delivering 250W of power and 24Nm of torque.The motor provides pedal assistance to help riders accelerate from junctions, tackle inclines and maintain momentum through urban environments.Its rear hub positioning keeps the electric drive system compact and allows it to work with Brompton's folding frame design.The assistance system is designed to respond naturally to rider input, helping make everyday journeys less physically demanding while retaining the familiar feel of cycling.345Wh Greenway BatteryThe Brompton Electric C Line features a 345Wh Greenway battery, providing a claimed range of up to 90km under suitable conditions.Actual range will vary depending on factors such as assistance level, rider weight, terrain, temperature and riding conditions.A full charge takes approximately five hours, making it practical to recharge between commutes or overnight.Intelligent Range PredictionThe e-Motiq system includes intelligent range prediction designed to provide more personalised estimates based on how the bike is ridden.During the first 100km, the system learns the rider's riding characteristics. It then continues refining its range predictions approximately every 6km.This helps riders better understand their available battery capacity and plan journeys with greater confidence.Brompton Handlebar Control ScreenThe Brompton Handlebar Control Screen provides a convenient way to manage the electric assistance system while riding.Positioned on the handlebars, it allows riders to interact with the e-Motiq system without needing to reach for the battery or other components.Its compact design keeps the cockpit straightforward and accessible for everyday use.Brompton 4-Speed DrivetrainThe Brompton 4-speed drivetrain uses a dedicated derailleur system with a chain pusher and an 11-18T cassette.Paired with a 54T chainring, the four gears provide a useful range for everyday urban riding, allowing riders to adjust their cadence when accelerating, climbing or maintaining speed on flatter roads.The mechanical drivetrain works alongside the electric assistance system, giving riders control over their pedalling effort while the motor provides additional support.Brompton Dual Pivot Caliper BrakesBrompton Dual Pivot Caliper brakes provide controlled stopping power for everyday riding.The dual-pivot design offers responsive braking, helping riders manage speed through traffic, junctions and changing road conditions.Their compact construction also integrates neatly with the Brompton's folding design.16-Inch Wheels and Schwalbe Marathon Racer TyresThe Brompton Electric C Line features 16-inch wheels with double-wall rims designed for everyday durability.Their smaller diameter contributes to the bike's compact folded dimensions while providing responsive handling for navigating busy streets and tighter spaces.Schwalbe Marathon Racer tyres offer a balance of rolling efficiency, grip and puncture protection, making them well suited to commuting and regular road use.Practical Finishing KitThe Brompton Standard saddle provides support for everyday journeys, while the extended seatpost allows riders to adjust their saddle height.A folding left-hand pedal reduces the bike's overall width when stored, while the 6061 forged aluminium crankset features an integrated chainguard to help prevent clothing from contacting the chainring.Weighing approximately 17.9kg, the Electric C Line combines the durability of steel construction with the additional weight of its motor, battery and SuperRoll+ system.Designed for Everyday ConvenienceThe Brompton Electric C Line 4-Speed SuperRoll+ combines electric assistance, compact folding and improved portability in a practical urban bike.Its e-Motiq motor helps make commuting and longer journeys more manageable, while the SuperRoll+ system makes moving the folded bike easier when cycling isn't possible.For riders combining cycling with public transport or working with limited storage space, it offers a flexible way to make electric cycling part of everyday life.
