Check out Toms kid karrier a.k.a. a customized Xtracycle. You don’t necessarily need to have a pull behind kid trailer to haul the little ones around. Tom used his fully out fitted Xtracycle with Magic Carpet and all and added 3/4″ thick walled copper tubing and wrapped PVC.
This is a great Xtracycle conversion, using low cost materials that can be found at the local hardware store. Many extras can be added to the Xtracycle to customize it for almost any need. Tom is using this for three kids now, in a few years, two, then maybe just one will fit on there, but for now it works great for three, and I love the roll bar look. Thanks for the photos Tom and great job!
