take an old front hub w/ quickrelease. Use Ubolts to attach it to your chunk of wood.
The problem with towing a bike up that high, it become unwieldy. the best towing happens when the bike is level. use BOB trailer with the extra hub and wood set up. you might even be able to Ubolt the hub directly to the floor of the BOb
