I have a cycle slider for my garage. It is a small 2 car garage but I fit by bike and two cars in there with the help of the cycle slider. There are cheaper ones out there but I have found there is no bow in the middle of this one like I've seen on some others. I set it on the floor, set the brakes, and roll off. I leave it there and when I return I ride up on it and put the kickstand down and leave it in gear. Un-do the brakes and roll the cycle slider and bike up against the wall. I even screwed down some angle iron to the floor so I push the slider up to the angle iron and it's in the same place every time without any danger of hitting the wall. It works great and really gets it up to the wall without having to manuver the bike all around to get it where you want it.

I did a web research. In Italy there is only the Bike Shuttle parking systems (www.bike-shuttle.it). There free and drived platforms. I prefer the drived platform because I can be sure to put the Road King always in the same place and be sure to avoid to hurt the wall. Does exist a drived platform with a front wheel block in America like the same of the photo?
