The wheels are the reason to look at this scooter. At 16 in, the inflatable rubber tires are big enough to keep rolling over cracked sidewalk, gravel driveways, and the seams that stop smaller wheels dead, and the air inside takes the sting out of rough ground so a longer ride stays comfortable. A slip-resistant tread keeps the contact patch honest in the corners. Underneath, a steel frame and wear-resistant aluminum alloy wheels carry a 220-lb maximum load across a deck 54.75 in long by 22.75 in wide, which means older kids and teens get a scooter sized for them rather than a scaled-up toy. The handlebar adjusts between 35.5 in and 37.75 in for a fit that keeps up with a growth spurt. Brakes at both wheels give two ways to slow down, and a kickstand parks the scooter upright at the end of the ride.
