The wheel holders will accommodate all wheelbases, even small children’s bikes. You can reverse the wheel supports for the really small bikes.
The long rubber-padded wheel straps hold tyres up to 3.25” wide; pull on them to tighten, and use the quick release to loosen
The BUZZRACER H2 is entirely suitable for carbon frame bikes; the rubber-padded bike frame cradles rotate 360 degrees and, again using rubber-padded straps, they hold any type of tube firmly but gently.
The maximum permitted load is 40kg (88lbs), with no bike weighing more than 20kg (44lbs)
Electric bikes up to 20kg may be carried, although the BUZZRACER series is not optimised for e-bikes (see E-Scorpion for e-bikes); the down tube size is limited to 75mm diameter (3″); whatever bikes you have, always load the heaviest bikes nearest to the car
There is a built-in locking cable to secure your bikes; as usual with cable locks, it’s a deterrent only.
