Review on Efficient Adams Hitch Pin for Trail-A-Bike - Enhanced Functionality and Security by Darion Wooten

This is a must-have trail-a-bike connector pin that I bought cheap. It looks like it will work, I wish the nut was self-locking or the clamp design was a little more secure, similar to the latch on our bike trailer, but I suspect the design has been proven to work since they've been using it for years. I won't be able to test it until spring, when hopefully my daughter will be big enough to ride it.
