The EzyRoller Mini is a mini version of the Classic designed for younger children; it's smaller and lighter so it can be carried and packed easily. In no time they're curving like they were born to it.Rider Age/Max Weight/Height:Each rider is different but the Mini is our smallest seat/frame and is ideally suited for kids from 30 to 45 lbs (13-20 kg) and from about 31-33" (78-83cm) up to 37-39" (93-100cm) tall. Over these height/weight parameters, the Classic model is probably a better fit. We usually recommend the Mini for kids from about 2 to 4 years old. The maximum recommended weight/height is up to 66 lbs (30 kg) up to 42" (105 cm).If you have any question, please contact us!Length: 19/23"(48/58 cm). Extendable: one extension included in the box to allow adjustment to kid's height.Width: 15" (37 cm)Height: 11" (28cm)Weight: 9.2 lbs (4.2kg)If you are looking for an EzyRoller for preschools, schools or institutions, then our Education models are probably better suited for heavy duty usage.All our EzyRollers carry a 2 year warranty on the frame; this however doesn't cover normal wear and tear, poor maintenance (such as leaving it in the rain where it will rust) and parts such as wheels, grips and seat.
