Review: Perfect replica of the original. - It works great! As far as I can tell it is a perfect replica of the original part for the Schwinn bike trailer. It is OBVIOUSLY not designed for bikes with quick disconnects on there wheels so don't expect it to work with out some tinkering. It fit fine on my wife's Schwinn beach cruiser. (even with the wheel hub mounted kick stand) It wont fit my 29er without modification. (wouldn't put it on anyway. Don't want anything extra on my hub when on the trail) I would definitely recommend it! But make sure it will work on your bike before buying it.
Review: Perfect for a multi-bike family - Perect product. Does just what it says. We purchased the Schwinn Joyrider. It already comes with 1 coupler attachment, but having an extra one so that my wife and I can both have one on our own bikes makes family bike rides much easier. My wife will ride until she gets tired of pulling the extra weight, and then we'll pull over for a pit stop, pop the pin out, unhook the trailer, and hook it up to my bike. It takes no more than 60sec. - seriously. We leave the coupler on our bikes at all times. We do leave the pin with the trailer instead of on the bike - that way, whichever bike is not towing the trailer won't be subjected to a ratteling pin. We just keep the extra pin in the house in case the original is ever lost.
