Fifty years of folding expertise don't happen by accident. The Brompton Electric C Line is where all of that earns a proper electric upgrade.
The C Line Brompton has always set the standard for hand-built folding bikes, built to go where no other folder can, onto the train, into the office, up three flights of stairs. The 2026 Brompton Electric C Line keeps everything that made it good and adds the all-new e-Motiq system, developed in-house by Brompton after proving itself on the G Line. It's smooth, well-integrated, and makes hilly commutes feel like a completely different proposition.
For anyone considering Brompton bikes and curious about the electric version, weight is worth knowing upfront. The e-Motiq system and battery add some over the standard C Line, but the 345 Wh battery and its range, up to 90 km on a single charge, make that a trade-off most commuters are very happy with.
Features
- Brompton e-Motiq system: designed by Brompton, not an off-the-shelf motor bolted on. First proven on the G Line, now on the Brompton Electric C Line 4 Speed. The fold stays tight, the ride stays balanced.
- Up to 90 km range: serious range for a folding electric bike. The battery removes with one click for charging at your desk, in a café, or anywhere with a socket.
- e-Motiq Handlebar Control: power mode switching, Start Assist for uphill restarts, and live range estimation, all from the bars without fumbling for your phone.
- Over-the-air updates: Your Brompton 4 Speed electric system updates itself automatically. No trips to the shop, no faffing with cables.
- Torque sensor assist: the e-Motiq system reads how hard you're pedalling and matches the boost accordingly. On a climb it gives more; on the flat it backs off. It always feels natural.
- Four gears, three power modes: enough range for most UK commuting terrain, with three power modes so you can dial in exactly how much help you want on any given day.
Available in Red Plum, a deep, considered colour that looks sharp in the city, the Brompton Electric C Line in Plum Red is a proper commuter tool that happens to look brilliant.
The Brompton folding bike formula is already hard to beat, and with 90 km of assisted range on tap, the electric C Line makes a very compelling case for itself.
