Good racks should be simple, tall and not very thick so a variety of locks will work with them. Those front wheel racks are too low to use a U-lock. And some of the hoops are too thick. A good rack should allow you to place the bike up against the main frame tubes and front wheel.

Rubber coatings are nice. Rounded rack members are better than square/sharp edges. I like loops, U's or the lollipop posts.


Also check with buildings and grounds whether this is going to get buried with concrete footing or bolted to small holes in pavement. Some of these designs are not for inside parking garages.
