Last week I had a Hayman Reese towbar fitted to my Honda hatchback so I could avoid having to put my bikes on the roof racks.
As it's only a small car I won't be towing but it can tow up to 1000kg if need be.
This morning I picked up a Thule 972 3 bike carrier off Gumtree to throw the bikes on- I tested it with one of my taller bikes, my 1977 Raleigh Grand Prix that I converted to 3 speed and flat bars.
Looks like there's plenty of clearance so it will be good to get out there and test it.
