All other things being equal that probably aren’t equal (price, space, aesthetics, etc), I think this bike rack is my new favorite.
It seems optimized for “the Sheldon Method” of locking in which a U lock is wrapped around the post and the rear wheel inside of the rear triangle.
When the rear tire is placed in the tire guide, the wheel is lined up perfectly for locking using a mini U lock. You can lock through the seat tube if you prefer. With this old bike and its skinny steel tubing, in fact, I can slide the Kryptonite Mini through both the wheel, the seat tube and the bike rack post.
Note that the wheel guide is positioned such that the drive side is away from the post.
This is at San Jose City Hall. The new Monterey Bay National Marine Sanctuary Exploration Center in Santa Cruz also uses this style of bike racks.
