Pictures of Carrot!

I promised my parents pictures of Carrot.

She's a beaut.

As you may notice, the bike lock is a half-ring connected to the wheel cover that goes through the spokes of the rear wheel. While riding, the key stays in the lock. To lock the bike, I push a metal tab that extends the ring through the spokes of the wheel and connects to the other end of the ring. Unlocking the bike again is as simple as inserting the key and then pushing it to the side - the extending part of the ring snaps right back.
Of course, this system somewhat trades convenience for security, but I quite like it.
