The EzyRoller Classic - for ages 4 years and above - does not require pedals, chains or batteries. No need for a downhill slope to move forward. Just an easy gentle swinging movement on the front paddle generates forward momentum. The child also uses their feet to steer the EzyRoller. It can be ridden on any hard surface and can be ridden indoors as the non-marking high resistance wheels will not damage your floors. EzyRoller’s handbrake has a long lever for easier and safer operation. It is super-easy and super-fun!
