Can a bike rack fit on my Class 4 Hayman Reese Towbar

A Class 4 hitch towbar typically features a heavy-duty 2-inch (50x50mm) removeable receiver, they are the industry standard for robust, hitch-mounted bike racks. Always double-check your vehicle's specific payload and tongue weight limits in your owner's manual to ensure the combined weight of your rack and bikes doesn't exceed those ratings.
