I normally ride off from home, but once in a while I'd like to haul my bike to a different location to ride. For reasons, I don't want to buy a rack. The bike weighs 50 some pounds, so it's liftable, but awkward. I'm concerned that brute-forcing it into the back I would end up damaging something. Has anyone figured out a good improvised ramp or something to get the bike into the back of an SUV?
