hi I need advise again, ive got myself a 4x3 trailer, got myself a wooden lid , now I want to fit x 2 bike racks im looking for ideas or links or pics on how to fit them
regards

What about a couple of these bolted to the top for the front forks, then a ratchet strap to hold the rear wheels down.

A mate of mine had a similar thing welded to a tie bar that went across the back of his pick-up. Nice and quick yet easy to remove.

You can get them for bolt through axles if you run those too.
