The 50N·m torque ensures responsive acceleration and smooth hill climbing up to 30°. It features dual suspension—front fork and central shock absorber—for superior comfort on rough roads. Additional highlights include Shimano 7-speed gears, hydraulic disc brakes, full fenders, and a convenient front basket for groceries or bags. Suitable for riders over 160 cm tall, the EM20 supports up to 100 kg and includes a 3.5-inch LCD display, turn-signal tail light, and IP65 waterproof rating for year-round reliability in all conditions.
