When the time comes, go ahead and replace your old 16"x2.125" inner tubes with this 16"x2.125" heavy duty thorn resistant kick scooter inner tube with a straight valve from Sunlite Cycling. Inner tubes are the most commonly replaced kick scooter parts, and these excellent Sunlite inner tubes will keep you rolling down the mountain trail as well as over the suburban streets and sidewalks.

Note: When inflating a bike tube, please use your best judgment. The recommended PSI for an inner tube can vary depending on elevation and air pressure, and should not be taken as absolute.
