My two penth,
I like the roll-a-ramp thing but dunno if it's going to be stable enough to walk the bike down. Limits of the ramp is ~300-400 kg depending on length. The dry weight of the bike is ~200 kg add fluids to that (~10 kg?) and the average mass of a grown adult and kit ~100 kg and your getting to the upper limits of the longer ramps. Then there's the bouncing mothion that walking down the ramp could transfer to it and the extra stress that might cause. There's also the problem that it's a lump of metal that could be weighed in by your local scallywag.
It's abit of a grim subject to bring up with him but is there a chance your neighbour is going to need an access ramp in the future? Ask him, he might have been thinking about it himself and you could maybe club together for a permanent structure.
