I mentioned buying a bike in an earlier post, and since I picked one up, I've been riding back and forth to work. I just keyed a rough estimate into Google Maps and found out it's about 12 miles roundtrip, including a stint over the Williamsburg Bridge, my little version of hell in fifth gear. Since I haven't been able to get a free weekend to ride around lately, I figured I'd share my Google Maps route with you and talk a bit about what it's like to commute via bike in New York.
First, my commute:

I cut off the start and end points because the internet is scary.
Anyway, the real meat of the trip begins at the Williamsburg Bridge. It's really long and steeper than it looks when you're in a car, but otherwise it's a model of bike-friendly engineering. On either side of the bridge there's a two-lane mini-road on which bikers and walkers can cross without having to deal with cars. All the bridges I've ridden over have something similar, but what's strange about all of them is they want walkers to walk on the left and bikers to bike on the right, meaning you're face to face with people coming on foot in the opposite direction. I guess it's a safety thing, but it's disorienting the first time you go over.
After that, it's a couple quick turns to the worst part of my trip: Houston street. Houston is the last major street before the avenues start, and it's a goddamn death trap. The road's poorly maintained, and since there are work crews out there every day, there's no shoulder escape route, since they have barriers up everywhere. This is the only street where people honk at me for being in the way. It's also the only street where I scream "fuck" at people.
From Houston it's pretty smooth sailing up Sixth, since it has a bike lane, which is absolutely awesome. It's on the left side of the street, so you don't have to tangle with buses randomly moving into the shoulder (buses LOVE to fuck with bikers otherwise - everyone in the MTA is a serial killer), and unless a rogue cab decides he absolutely needs to pick up someone on the left side of the road in rush hour traffic, the only drivers I have to contend with are delivery truck drivers, who at the very least are professionals and have made careers out of staying out of accidents.
From there I'm pretty much at work. It takes me about 40 minutes door to door, which is actually less than it takes me on the subway on bad days. There's also the added exercise benefit, and I know the Lower East Side like it's my job. Or at least my hobby.
