Is there some sort of towing attachment I could put on my bike that would create a center pivot point for the lawn trailer?
For more context, I have a typical garden wagon -- 4 wheels, the front two turn, the back two are fixed, it can pulled with a handle or towed with a garden tractor using a clevis pin attachment that is centered in the lawn tractor.
I was wanting to look into towing it with my bike -- I've been looking at trailer arms for bikes and see that unlike with my garden trailer, the bike specific trailers have the towing arm offset to one side of the trailer. I suspect this has something to do with how the trailer "follows" the bike -- the offset arm allows it to follow directly instead of to one side. If also see that in the trailer arms for bike trailers it looks like the pivot point is on the bike-side attachment, so if I were to use a similar arm to tow my garden trailer it would have two pivot points, which would be difficult to manage and possibly dangerous.
I'm thinking instead of something that attaches to one side of the back wheel (on the bike) and pivots near the wheel, I could use something that attaches to both sides of the rear fork (maybe not on the wheel nut) and stays in line with the bike, allowing the trailer to pivot on the clevis pin only.
