The Atera wheel holders are deliberately formed like wheel chocks in order to eliminate the enormous lateral, drag and shear loads.
Thus, the wheels are protected against any damage - a small detail with a big effect.
That is competent construction design paired with shapely product design from Southern Germany.
The lockable Strada distance holders can be swivelled and turned in each direction. For the theft protection, the ratchet straps are enforced with a steel core while the bike frame itself is held softly and secure by soft rubber cushions.
Even the ratchet system itself is equipped with an overload protection: The desired tension is reached by using the ratchet - when the tension exceeds the desired level, the ratchet band automatically jumps to the next tooth. The optimal tension remains and is secured when the ratchet lever is locked.
Atera carrier systems undergo very strict tests demanded by the industry norm as well as the automobile industry.
Assisted by the ADAC, the European automobile club unions, several European governments as well as additional consumer organisations, standard crash test methods have been developed under the name EuroNCAP (New Car Assessment Programme) since 1998.
The following is applied for a City-Crash test: Carrier and load are safely secured during a head-on collision with 30 km/h and do not dissolve from the vehicle.
