How do the bike racks attach to my towball?
The bike racks fit onto the ball itself. There are no straps or supports coming into contact with the car making them very easy to fit. The Euroway has a rachet handle built into it to tighten on and the EuroClassic has a pull down handle. The Bolton 9705 uses the existing bolts in your bolt on tow ball and all the rest use a special spanner which is provided in the box.
