Now you can take three other friends mountain biking or to the time trial races by extending your Thule TranSport T2 Two-Bike Rack to a four-bike rack with the Thule TranSport T2 Bike Add-On. The TranSport Add-On works only if you have a 2in receiver hitch.

• SecureHook latches onto the front wheel, while an adjustable wheel strap quickly attaches the back wheel to the reinforced tray
  
• Hitch Switch lever tilts carrier away from vehicle for trunk, hatch, or tailgate access
  
• One-Key Locks secure the bikes to hitch rack and can be adapted to use the same key as your other Thule locks
  
• Snug-Tite-2 receiver lock eliminates hitch-to-rack wobble and locks the hitch rack to your vehicle
  
• Fits bikes with 20in to 29in wheel diameters and bicycles with up to 3in-wide tires
