The DYU D3F is DYU's smallest folding e-bike, an ultra-compact 14-inch frame designed for riders who need to carry it onto a train, tuck it under a desk, or store it in a small apartment. A 250W motor with throttle and pedal-assist modes and front and rear disc brakes cover the basics for short urban trips, and at 41.9 lbs with a 264 lb payload capacity, it stays light enough to actually carry rather than just roll.
