I see this type of design every so often- where they use some kind of hook to hand your bike up with its front wheel. It works on 99.9% of bikes, but unfortunately it doesn't work for those of us with old style HED, Mavic Cosmic, Bontrager Aeolus, and Flo carbon wheels, where the carbon is a soft fairing and the spoke nipple is anchored on the aluminum rim.


They need to nip this kind of wheel hanger design in the bud. The better way is to have an arm that grabs the saddle and pushes the bike against the tray
