Not cumbersome and keeps the bike looking "normal". My wife and I live about two blocks from the grocery store and want to be able to use our bikes to get the goods. We have limited space were we store our bikes and the storage will not fit a trailer. I want my wife to be able to easily hook and unhook from the trailer while I am at work.
1 X Male 3/8 pneumatic connector
1 X Female 3/8 pneumatic connector
2 X 1/4 (or smaller) eye bolts
Step 1: Disassemble the Female connector
Using needle noose pliers reach into the threaded side of the connector and grab the spring and give a pull. The spring and another small piece will come out. You may discard them they will no longer be needed.
Before continuing note the action of the small ball bearings and the slide section of the Female connector.
Using some pliers and a wrench loosen/ split the connector. Do not attempt to work the slide while the connector is apart. Other wise you run the risk loosing the ball bearings. Set the slide section to the side until you are finished with fitting the eye bolt.
