Not my "Moots Pugsley", but I'm preparing to build something based on this picture. Notice the King Headset as part of the trailer's coupler design. This is my favorite "homemade" trailer design I've seen. I have the fork part of an old BOB Yak that I'm planning on utilizing in my build, but I can see how adding a stout headset would be better than the skinny, long bolt with plastic washers that BOB used in their design.
Anyone have any information on this trailer? I can't figure out what it would be used for, or how it can be used to carry anything. I am thinking it's just a frame for throwing some free-radical panniers on.
I don't see the purpose of having that rotor on the trailer's wheel - I guess you could use it as a spare, and then put the flat tire in the trailer for the ride home, as long as there was no weight to bottom out a 4" tyre without air.
Also, are those wires sticking out near the axle? I don't see anything else electrical on this rig.
