2002 UNI-GO single wheel trailer - from the years when these were made in New Zealand.

Comes with items in the images:
-Trailer, fully functional and ready to tow. Has combination lock for the hatch, and I have the combination.
-Uni-go kit for the bike-side 7-pin electrical connection (which I did not need)
-Bike-side receiver to connect the trailer to the bike (bike hitch not included).
-The original 7-pin wiring harness (trailer side). The previous owners adapted the factory 7-pin to a traditional, flat, 4-pin connector as shown using a bike-side 7-pin connector with a 4-pin tail. The original 7-pin is secured to the tongue, and the 4-pin is how I have operated the lights.

I purchased this from local friends last year, and my needs for additional capacity while riding have changed so I no longer need the trailer. My friends had the trailer painted to match their bike (including the roadrunner graphic). They changed the wheel bearings and then pulled the trailer from Minneapolis, MN to Nova Scotia and back without issue. I then acquired the trailer and did the following to it:

Since May, 2022
-New tire, Metzeler ME7 130/70-10. Not because the original was lacking tread, rather because the original was 20 years old.
-New wheel bearings (Timken 6301-2RS). Not because they were needed, rather because I like to know what I'm riding on.
-Added paint protection film to the leading surfaces. There were some rock chips and such on the forward facing surfaces already, and I had some extra paint protection film, so I put some on the trailer. I'm not a professional installer, but it serves the purpose.

The trailer is in overall great shape, and I keep it indoors in a spare bedroom. The paint does show some small hairline cracks in the hidden tight-corner features of the fiberglass body.
