SIZE: 20" (406mm ISO bead diameter) - uses 1.75"-2.125 wide tires. HUB SPACING: 100mm FRONT / 110mm REAR. DRIVETRAIN: SINGLE SPEED, 16T or larger freewheel.Axle size: 3/8 front and rear. NOTE: Skyway mag wheels do not have a lip for the tire bead to "pull" against. Therefore, installing tires on these wheels is a challenge. You must first mount the tire/tube on the wheel and add just enough air to give the tire form.
Then position/center the tire on the wheel, inflate a bit more, adjust the tire, etc. Until the tire is positioned evenly on the wheel before fully inflating the tire.
