I just recently ordered one of these to solve some storage issues I have with my ST. What a letdown. Unmentioned anywhere on the site is the fact that you really need a polished/fully finished floor for this thing to work correctly. My floor is concrete, and while not billiard table smooth it is far from being rough or so I thought. I've almost tipped the bike over twice now, it seems the wheels get caught on the smallest imperfection in the floor or small pebble. The worst part of this is that included with the item is a printed info sheet with instructions AND their return policy. They'll take it back if I pay the freight and absorb a 15% restocking charge, which I am quite willing to do. Problem is they WILL NOT RESPOND to my emails. I guess they are just hoping I will go away now that they have my money. Lesson learned, buyer beware. It's gonna make a nice (albeit pricey) boat anchor.
