Compatible with the bikes with 2" to 4" width tires. Easy to assemble with the instruction manual. No drilling is required for this parking rack, so you don't have to worry about damaging the wall. Front and rear wheel parking is supported. Double-wheel trays fix the wheels to prevent the bike from wobbling or tipping over. Anti-slip PVC foot pads can prevent the floor from being scratched. This parking rack only grabs the tires when parking the bike and will not cause damage to the bike. It can be stored at home, garage, or apartment for retail and display. Removable storage when not in use to save space.
