In 2006, a company called Nextsport started producing a line of four-wheeled scooters, known as Fuzions. The scooters are typically bigger and heavier than Razor and Micro models. The early Fuzion models come with large, wide wheels, and an oversized deck for stability. Later scooters such as the Fuzion NX included smaller and harder wheels. It also included 360 degree handlebar spinning capabilities, unlike its predecessors.
