Bike shed solutions/ideas?

[nick crisp]

How about having the door jamb removable or hinged .

That would only partially solve the issue because the jamb itself is just the top piece of wood. There'd still be about an inch of rise to get the bikes up onto. Also, the jamb is rising that inch or so above the shed floor, so got to get over that when getting the bikes out again, which your idea would solve. Hmmm.......
