Swagman's Semi 4.0 2-Bike Add-on is the perfect complement to your Swagman Semi 4.0 hitch rack (sold separately). The Add-on quickly bolts to the end of your Semi 4.0, turning your 2-bike rack into a 4-bike rack for twice as much fun. Simply load your bike into the tray, move the Semi's ratcheting arm over the front wheel, and press it, and then secure the rear wheel with the strap. This rack has zero contact with your bike frame to prevent paint wear and scratches during transport.
This rack mounts on the Swagman Semi 4.0 (sold separately)
