Overview

The Dahon K-Feather is a folding electric bike built around a 250W rear hub motor and a frame-integrated Samsung 21700 battery, aimed at commuters who need to carry or store the bike in tight spaces. At 26 lbs it is unusually light for an e-bike.

Dahon's DFS folding system is the bike's main selling point, collapsing the frame in three steps for storage under a desk or in a car trunk. A torque sensor rather than a simple cadence sensor drives the pedal assist, which Dahon states reacts within 0.01 seconds.

Performance notes

The 250W hub motor produces 32Nm of torque, enough for moderate hill climbing, while the torque sensor adjusts assist power to match how hard the rider is pedaling rather than switching on and off at a fixed cadence. The battery sits inside the frame tubing instead of an external pack, which keeps the bike's profile clean and its weight balanced.
