Best runner up: TITANKER Bicycle cart Attachment

Buy on Amazon

If you want nothing short of the optimal attachment for your regular usage, this titanker bicycle cart attachment is certainly a wise investment. This one works for bikes that do not have a flat area where your axle goes through the frame. It mounts on the left rear axle by removing the nut and attaching between the nut and the frame. It goes to the inside next to the bike frame. It is a solid chunk of metal, where the OEM bracket is just a cheapo stamped affair.

This coupler is longer and has add'l holes that allow more adjustments for larger bikes. It basically is a lock washer with a little hook for the frame which keeps the hitch in a stationary position on the axle. The diameter of the hole that attaches to the axle is 1/2 inches & the outer diameter of the part that attaches to the axle is 1 inch. It comes with an additional trailer coupler attachment, both mom and dad's bikes can be outfitted to tow the kids trailer, and your kids will enjoy the bike ride.
