Don’t let your adventures be limited to the pavement. The 16+ Wheel Kit improves handling over snow, sand and gravel. The kit includes two 16x3” push button wheels with a knobby tread. A wide range of acceptable tire pressures let you adjust the stiffness to your liking. Let a little air out and the tires soak up the bumps for your passengers. Say goodbye to the sidewalk. Constructed with aluminum rim/hub and stainless steel spokes.
