EV4 is designed by Aero-service in Poland, using low weight components highly durable aeronautical aluminum alloy, constructed like an airplane. The main frame of the vehicle is riveted just like in the case of airplanes to make it more durable and lightweight. The independent suspension uses an adaptive suspension system to adjust to the shape of the terrain at any given moment. Regardless of the surface type, terrain, angle of inclination of roads and travel, the EV4’s wheels uniformly and evenly touch the ground. Thanks to the electric drive as well as gear belts the noise emission is close to zero, which has a positive effect on the driving comfort. The vehicle’s low weight and the use of modern and efficient lithium ion batteries achieve a 100km driving range. Shocks are absorbed by two bicycle shock absorbers with adjustable hardness and damping. Hydraulic disc brakes on 4 wheels allow for very short braking distances, making the EV4 very safe. The EV4’s four wheels result in stability superior to that of single-track vehicles.
