Brompton Electric C Line

The original Brompton, made electric. The Electric C Line takes the all-steel bike that’s been folded onto train racks for decades and adds Brompton’s e-Motiq system: a rear hub motor, a removable battery and up to 90 km of assisted range. It’s the most robust way into the electric range, in the widest choice of colours.

At a glance

Steel frame, 4-speed gearing, and the full e-Motiq system with three assist modes. The battery clicks off its mount to charge at your desk or kitchen table, and the fold is the same one Brompton has refined for fifty years — small enough to sit under a table or come aboard the train as luggage. From 17.3 kg with the battery, 13.8 kg without.

Who it's for

The Electric C Line suits journeys made in stages: a few miles of road, a train in the middle, an office at the end. The motor takes the sting out of hills and headwinds, so the route no longer has to be planned around them, and the steel frame shrugs off daily handling: locked, carried, folded, unfolded, repeated. If your miles are mostly city miles and you like the original Brompton feel with a little help from a motor, this is the one to try at an appointment.

Build & technology

Brompton developed e-Motiq itself: a rear hub motor with a torque sensor, a removable 345 Wh battery and a handlebar controller. Assistance follows your pedalling across three modes, with Start Assist for pulling away. The system is independently certified to UL2849, and updates arrive through the app. The bike comes fitted with folding pedals, a wide saddle, ergonomic grips and a roller rack.

FAQs

Up to 90 km, depending on assist level, terrain and rider weight. The e-Motiq app gives a live range estimate that becomes more accurate as the system learns how you ride.

The Electric P Line adds a titanium rear triangle and carbon fork, making it around 1.5 kg lighter with a smoother ride feel. The C Line is the all-steel original, available in more colours. Same motor, battery and range on both.

Yes — with the battery removed or the system off, it rides like a regular Brompton, and folds identically.
