After a comprehensive test of the ADAC they can recommend only three bike carriers. (see photo gallery!) The rest of them give the bikes sometimes dangerous amount of space.
The testers have investigated the 16 newest and most popular bicycle racks with 3 mounting styles: rear, roof and hitch. The overall rating of "good" got 8 products, the grade "satisfactory" 6, one each was rated "not satisfactory" and "poor". The products cost from 13 to 495 EUR and are commercially available. Test criteria were safety, handling, processing, and the additional fuel consumption of cars.
