a few bicycle commuter tips...

the commuter and the bike lock-
it amazes me how many cyclist I see each day who ride with their lock bouncing around on their handlebars
a better idea...
-get the u-lock bracket for the bike
-put the lock in your bag
-better yet... do not drag the lock to and from work
leave the lock at the spot where you lock the bike each day
(unless you are going to need the lock on your way home)

commuter clothing tips-
-keep your clothes at work; or at least most of your work
-get a separate set of shoes that you keep at work
-use the dry cleaner near your office
-ride in riding gear and work in work gear
