The Täger itself has as standard an anti-theft device. However, the fixing of Fahrräader is without anti-theft device. A lockable frame holder is available. I use to prevent theft the respective wedge socket of bicycles. The included frame holder designed quite universal. The fixing of bicycles with aluminum frame is probelmlos possible.
The support can be folded into a compact package and well off in the supplied bag in the garage to save space on a wall. There is no special holder is required.
The only disadvantage is the limitation to two bikes, as there is no extension kit for a third cycle for the Raven. The reason for this is certainly the folding mechanism.
The technical data of my carrier, as indicated in the type approval, depart from the information the product description on Amazon somewhat:

max. Load capacity: 60kg
approved for empty trips: yes
approved for universal transport: yes max 60kg payload
max. Speed: 130 km / h
ATTENTION: The bicycle carrier is unsuitable for towbars with an aluminum ball head (for example as the Audi A4 and A6)
