I was in the market for a new bike trailer. My current trailer was heavy, cumbersome and it was becoming increasingly difficult for your arthritic, geriatric, scribe to single-handedly load bikes onto it. Also my back-up team (the wife) can't reverse a trailer.

The Motolugs are available in four versions. The SE is a single that can carry 350kg and weighs 65kg.
