This high-tech foam material is an ideal alternative to conventional rubber tires with tube and casing for the Berg Buzzy. Thanks to its composition, the EVA tire is just as wear-resistant as the usual rubber tires, but punctures are a thing of the past. The Berg Buzzy has a fixed connection between the front pedal axle and the rear axle. This means that the movement of the legs is immediately translated into the movement of the rear wheels. This makes the Berg Buzzy extremely simple and easy to drive. Both forwards and backwards. Thanks to the four wheels, the Berg Buzzy offers excellent stability. Since tricycles have one less wheel, they are very unstable and prone to tipping over. When cornering sharply or quickly with a tricycle, dangerous situations easily arise. On the Berg Buzzy, however, the wheel lines run parallel and further away from the rider. This makes tipping over virtually impossible. On a tricycle, the pedals (and therefore the feet) and the handlebars (and therefore the hands) are directly connected to the front wheel. On the Berg Buzzy, however, the pedals are connected to the frame. No energy is lost by the handlebars or pedals turning away when the child pedals or steers. The child can ride off easily and smoothly after getting on.
