Older Burley Piccolo 6 speed trailercycle for sale with Moose rack. Not sure of the exact year, but from back when they were still made in Oregon, so pre-2006. Details on the current version are here – https://www.burley.com/product/piccolo/ . It appears to be basically the same except the new ones are 7 speed.
It’s been used but is still in great shape and has been garage kept all it’s life, the kids have just outgrown it. Pictures are here – https://photos.app.goo.gl/gJ7UQ3pwNHbEZkQ18. Located in Mt Lebanon.
