Here's something one of the local bike shops uses. They even put Goldwings on theirs.
Of course, this is drawn without all the necessary braces, locking pins and reinforcments, etc. that you would need... so you can see the concept more clearly.
(And, also, my light blue wedges aren't drawn exactly right. They should sit flat on the floor when the ramp is extended... for supoort.)
I also think they have both handles on the sides of those wedges, and maybe some kind of a winch setup pulling the blue ramp from the front to assist in the lifting. I'm not sure, it's been years since I saw this. But it worked perfectly.
I could see how a worm drive garage door opener could be adapted to power this thing if your bike is one of the heavier ones.
