What struck me: the wheels are not perpendicular to the support, but tilted slightly backward - the Handrails are a bit too long. Not sure if that should be so. (In the photos is not clearly visible).
The plate holder is not perfectly solved - it already requires some force to release the retaining clips.
We have 2 bikes (MTB, 27.5 ") and we leave the center bracket empty - otherwise it would be pretty tight.
All in all a great support (I have no comparison to other)
(Each a half star deduction for the plate holder and the "crooked" status)
