The list author says: "I recently started bike-commuting to work. If you live within 15-20 miles of your work, are physician cleared for exercise, and want to make a positive change in the world, I highly recommend it! These are some of the things that make it easy and fun. Some are recommendations from pros, some are hard-learned lessons. I'm assuming you already have a bike that you're comfortable on."
"Get a flashing light if you're going to be riding in early dawn or dusk. These are not headlights, they won't light your way, but they will give cars a good warning that you are out there. Another rider told me that they are also good protection in case, knock on wood, you end up in court because of an accident. This one charges on a USB so you don't have to mess with batteries."
"You will need hydration. I like the camelback over a bottle because it's easily accessible and can hold keys, phone, wallet, sunscreen, and any other small essentials you want close by for your ride."
"And these will take care of any "unfresh" spots once you arrive. Keep them in your desk for a quick touch-up if you don't have access to a shower or prefer not to. I find that I typically don't need one after arriving in the cooler morning, but I do after returning home in the hot afternoon."
"Bike Snob is a good, fun, introduction to the many cliques and foibles thereof of cycling. He also remind you that as long as you're on a bicycle, trying to stay safe and obey the law, you're doing great, speed and coolness notwithstanding. (I have neither, FYI.)"
