There are a bunch of forums addressing this online but no real solutions, ideas, pictures. the ultimate goal is to put a single, Large frame mountain bike with 29" tires into a piper archer ii. Obviously, removing both tires is a must, and I have a purpose built tarp cover thing for the greasy gear system. I'm going to attempt to put my road bike in today and if it seems to go in with ease I will try the mountain bike. I'm thinking the frame is roughly the size of a torso and head so I should be able to put the seat and backrest of the front set down while I slide it into the backseat but we'll see... Anybody else have experience with this?
