Two speeds - 1.4 and 2.7 mph - are selected by a button rather than a pedal, so a three-year-old starts slow and moves up when the driving is steadier. Forward and reverse work the same way. The quad measures 37.8 x 22.8 x 27.6 in with a 14 x 7.5 in seat, suits riders 31.5 to 51 in tall aged 3 to 8, and carries 77 lbs. Charging takes 8 to 12 hours for a full battery. PP bodywork over TPR tires keeps the weight down to 30.9 lbs, light enough for a parent to carry it back up a driveway when the ride ends.
