<p>You don’t have to register it the day you move in, you can register it any time with TAPS (they’re located near the ARC). I bought my bike during winter quarter (didn’t need a bike for fall quarter since all my classes were in buildings within a 5 minute walk from each other) and I didn’t register my bike until the 2nd week of classes. Get a U-lock. Thieves can easily cut through cable and chain locks. Any kind of bike will do, but a lot of people will hate you if you buy a cruiser with ridiculously large and wide handlebars because they take up space and it’s near impossible to properly lock a bike up to a rack if its next to a cruiser with ridiculously large handlebars. If you want to get to classes faster, get a bike with skinny wheels, since bulkier wheels (like the ones on cruisers) tend to slow you down, and also, when you live in an apartment next year and that apartment ends up being far from campus, you’ll be glad for the speed in helping you get to classes faster.</p>
