Question:
Hello, I am interested in purchasing the Swagman E-Spec Pro Bike Rack, and would like to get a couple of measurements from you to see if it will fit my application. 1. I would need a measurement from bottom of the hitch rail to the top of the mast. 2. I would need a measurement from the bottom of the tire cups to the top of the mast. Thank you and I appreciate your time.

Hey David. The Swagman E-Spec Pro Bike Rack for 2 Electric Bikes item # S45SR measures 41.7" tall from the hitch pin hole to the top of the mast. So 42.7" if you measure from the bottom of the 2" shank. From the bottom of the wheel cradles, where they attach to the rack, to the top of the mast is just under 34" tall.
The Swagman E-Spec Pro Bike Rack item # S45SR has a 70 lbs per bike capacity and fits tires up to 5" wide. It is rated to be used behind a motorhome.
