Bicycle wheel security without special keys using Kryptonite Gravity WheelNutz and WheelBoltz

Kryptonite announced these products a couple of years ago and I completely missed them because I was so focused on their then-new “Messenger Mini+,” which is the Kryptonite Mini with a rear wheel shackle designed specifically for quick locking and unlocking.
Kryptonite also offers secondary protection for both wheels with either the Gravity WheelBoltz wheel locks (for hollow axle wheels) or WheelNutz locks (for solid axle wheels). WheelBoltz replace standard quick-release skewers, while WheelNutz replace the 15mm nuts used on singlespeed and fixed gear bikes.
The genius of these products is the use of standard tools for removal and installation. A pin secures the wheel lock so that a potential thief cannot turn the nut securing your wheel. The pin drops out of place when the bike is inverted so you (or your bike shop mechanic) can repair your flat tire, and a properly locked bike can’t be inverted. This video from Kryptonite shows how these bicycle wheel locks work.
