The main difference between the Thule EasyFold XT F 2 and the Thule EasyFold XT2 lies in the type of towbar and some specific features:

## towbar
- The Thule EasyFold XT F 2 is specially designed for FIX4BIKE towbars, which are made by ORIS. This towbar uses two side bolts on the ball neck as a guiding and securing system, which makes assembly and fastening particularly easy and secure.
- The Thule EasyFold XT2, on the other hand, is designed for standard towbars and is not specifically tailored to FIX4BIKE.

## Compatibility
- The EasyFold XT F 2 is designed for specific vehicles and towbars thanks to the special FIX4BIKE coupling, while the EasyFold XT2 offers broader compatibility with various towbars.

## Other features
- Both models share many user-friendly features such as the fully foldable construction, high loading capacity and the practical folding mechanism. however, the specific design for FIX4BIKE in the EasyFold XT F 2 makes it more tailored to those particular hitch systems.

Overall, the EasyFold XT F 2 offers a specialised solution for users with FIX4BIKE hitches, while the EasyFold XT2 has a more general applicability.
