I have developed and patented a bike rack that fits only in 2" recievers that hold three bikes. The rack also can be used as a high-end excercise machine as you can do pull-ups, dips, sit-ups and push-ups with it. Originally I built it for myself when I would get done running on the trail, I wanted to do just a little more PT and came up with this concept. Is there a market for this product? Would you buy one? How much? I envision making a stand for it so, you could use it at home without attaching to a vehicle. Any feedback would be appreciated as I am preparing to make an intial run of 50 of these. Where should I offer it for sale? Thanks
