...Commuting is much more unpredictable than sport or leisure riding, and rush-hour traffic can be unforgiving of a lapse of judgment, attention, or control. You can be pretty casual about what bike, but take what you're doing seriously. Get a really good helmet, and a helmet mirror. At night or dawn you'll need lights, especially on the front. I have two obnoxious, flashing, LED lights on the front, and one brighter one in the back. Most of my vehicle collisions have been cars that didn't see me and pulled out in front of me or into me, so I like front strobes. And if you hate bikers who ride on the road when there's a bike path, you'll soon learn why. Bike paths are the most dangerous place I've ever ridden. I've had a lot of collisions on bike paths, slammed on the brakes twice in the last two weeks to avoid a painful repeat. I don't mean to put you off your plans, I'd just hate to hear you were injured in a way I've learned to avoid.
