What makes EzyRoller such a blast? It is an addiction to the motion! There are no chains, pedals or batteries – it moves like a curvy snake, using the alternating right/left leg movements of energetic riders. The seat is comfy, the wheels are heavy duty and the handgrips are kid friendly. Award winning for so many reasons. Easy assembly, adjusts to accommodate taller riders. From EzyRoller, for ages 4-10 yrs.
