Aligator’s Magnetic Bike Rack is a uniquely versatile bike mount that’s compatible with 23 to 70mm tire widths. Super lightweight and compact, the Magnetic Bike Rack is highly portable - throw it into a backpack and use it on race day as a convenient way to keep the bike upright while administering last-minute tweaks. Via two powerful rear magnets, the mount anchors to any metal surface - a car door, the metal pole of a stop sign or street light, etc. The Magnetic Bike Rack can be anchored to non-metal surfaces as well using the rear screw cutouts. To eliminate stress on rims and spokes, this mount firmly grabs ahold of the tire with its concave tapered grooves. When anchored for vertical mounting, there’s an integrated nautical rope that loops around the wheel as a precautionary measure.
