Review on WeeRide Co-Pilot Spare Hitch: Convenient Silver Replacement Part by Josh Jeffries

I have an old Pathfinder bike trailer with an almost identical hitch on my bike. My wife wanted a hitch on her bike so we could easily attach a trailer to any of our bikes. This hitch is nearly identical to the original lift hitch (which they haven't sold in at least a few years). By taking a hacksaw and removing 1/8 inch from the square end of this hitch (where it attaches to the trailer), the hole on this hitch can be aligned with the hole on the hitch allowing the bolt to work. For these I'm wondering the inside diameter of the cavity, the square end of the coupler, is 1 x 1 inch.
