D-Rings have to be found for cheaper than that!!!!
What ramp is that and where do you store it? I see it's a nice wider one, those single 12' wide ramps look sketchy. You can get it up, but how do you get it down? (Talking about narrow ramps).
The ramp is an Ohio Steel folding aluminum ramp. I don't know where it was purchased, I got it for Christmas from my parents but it is a very nice ramp! When you dismount the bike, try to do the same thing as loading, find a hill, back up to it and that way when you're unloading, it's more level and easier to unload. If you have to unload from the bed onto level ground, just feather the front brake, keep it going straight and don't fight it. Takes a little practice but it's not bad.
