I'm in my second week of having to use a bike lock the first time commuting. Previously I was able to keep my bike in my office, so locking wasn't necessary. So I bought a heavy-duty Kryptonite NY lock with a 7' cable to run through both wheels. I feel like it's a pretty secure set-up given that the bike rack is right near a door with a security camera.
I leave the lock attached to the rack at night, so I'm not lugging it back and forth. However, I am still fumbling with the lock every morning-afternoon and haven't figured out a way to quickly attach the lock and cable. Does anyone have any tips for making the locking process any quicker? Part of my problem is our rack is not a very good design (and not many are) -- it's a basic upside down U shape -- and the lock just barely clears my frame after fitting around the post. So about half the time, the open portion of the lock falls off while I am looping the cable through the wheels.
I guess it's just a matter of working out a routine, but I haven't succeeded in doing that yet.
