This bike carrier is pre-assembled and fully assembled was a few easy steps. The manual is easy to understand and to read in German. The self-explanatory mounting on the trailer hitch is easily and quickly thanks to quick release. Bicycles, with different frame (large, small, oval, round), can be secure stable Thanks to the flexible frame holder. The belts for each bicycle wheels must be clamped fast. The transport of two bikes is no problem at least 130-140 km / h. Something critical but I would say that the Farradträgergewicht but is very high and that the support to my original Golf 6- towbar sits wrong, even though I have repeatedly readjusted. Conclusion: price-performance ratio
