Thule 934 Easyfold XT 3 bike towball carrier. 13 pin connection for electrics. This has max weight of 60kg and recommended max for any one bike of 30 Kg. We used it for 3 normal mountain bikes and sometimes for two turbo levo electric assists. It folds up easy, has wheels and a zip on off cover. No longer an option as no longer have a car with a tow bar. Photos to follow when I get it out of the back of the garage, it’s in as new condition. I think it’s worth £200.
