let me try to get this posted... My "utility" is an unknown year Worksman Adaptable trike...single speed (for now anyway...3 speed in the near future). Both trailers are InStep, the orange one did a great job for my 2 nephews until the bottom got shredded out. The last trailer is a larger InStep, with the jogging stroller additions, so I can actually "cart" it around separate from the bike/trike it's hooked to. My wife and I actually just added the rope net bottom to it today! Behind my Worksman is my wife's grey Kona Lava dome, that does its fair share of pulling too. The longhorn is a Schwinn I got from a neighbor...rides surprisingly well. I have named that one "Scare Tactics" lol.
