C Line 4 Speed Mid Bar 2026 Electric Folding Bike
Technical specifications
Description
Built on 50 years of Brompton expertise, the Electric C Line keeps the portability, handbuilt quality and grin-inducing ride of the classic Brompton — now with intelligent electric assistance. Fine-tuned around the new e‑Motiq system, it’s designed to connect city commutes and longer journeys with effortless confidence.
Smart e‑Motiq system
The bespoke system pairs a custom rear hub motor with a compact 345 Wh battery and an intuitive handlebar control to give natural, responsive assistance. The e‑Motiq torque sensor adapts to your pedalling and the system learns your riding style over the first 100 km, refining predictions and performance every 6 km thereafter.
Unrivalled portability and rolling modes
Brompton’s distinctive fold stays secure as you roll. Lift the seatpost for Shopper Mode or drop it for Suitcase Mode and use SuperRoll for easy one‑hand manoeuvring. Add the Roller Frame to unlock SuperRoll+ for faster, smoother rolling with a shifted centre of gravity.
Always improving ride
Start Assist, dynamic range estimation and over‑the‑air updates keep the bike current and personalised without you lifting a finger. The result is a natural, uphill‑friendly ride that continually gets better.
