The Dahon Curl Ei4 redefines folding e-bikes with its innovative vertical tri-fold system, collapsing to just 58 × 38 × 60 cm for unbeatable portability. Designed for riders who value freedom and flexibility, it’s ideal for urban commutes, train journeys, and compact storage at home or work.

Powered by a 250W front hub motor with a torque sensor, the Curl Ei4 delivers natural and efficient pedal assistance across five support levels. Its 245 Wh detachable battery (only 1.6 kg) provides up to 50 km of range, depending on terrain and riding style.

Built with a lightweight aluminum frame, this e-bike weighs only 17 kg, making it easy to carry. The Sturmey-Archer 4-speed internal hub ensures smooth, low-maintenance shifting, while mechanical disc brakes guarantee safe and reliable stopping in all conditions.

Practical features include full fenders, a compact LCD display for assistance control, and a rear rack (10 kg capacity) for everyday use. Suitable for riders 145–190 cm tall, the Curl Ei4 combines cutting-edge technology with everyday usability.
