The Domyos EL520 is a fully self‑powered cross‑trainer that needs no mains connection—pedal for a few seconds and its LCD console springs to life to track basic workout metrics like time, distance and calories. It uses a 6 kg direct‑drive flywheel and rolls easily on built‑in castors for repositioning. With a 39 cm stride length, 15 resistance levels and a robust frame rated for users up to 130 kg, it’s designed for effective home cardio training.
