Two flights of stairs? The horror. (That's right, you wimp, I'm calling you a wimp. Wimp!)

That parking line is just silly. Look around a bit, I'm sure you'll find something close to, or in, your workplace. Bikes aren't that large, you can squeeze them into all kinds of places. If you are concerned about your bike being stolen, then you spent too much on your bike. (Hint: You can always make it look like crap.)

And carefully examine the title of that lame New York Times article excuse you use:  Serious Riders, Your Bicycle Seat May Affect Your Love Life. Will commuting make you a serious rider? (Anechdotal evidence: I was a serious rider right through puberty and well into adulthood. My wife's putting my one-year-old son to bed at the moment. We were trying for all of a month. I'm still bitter about that.) Besides, if you use a bike with an upright position and choose an appropriate seat, you'll barely be sitting on your nads at all.

All kidding aside, and there's puh-lenty of kidding above, along with your reasons not to commute by bike, maybe you might want to list the reasons in favour as well. No? Then, at the very least, you won't have jerks like me attacking you for what appears to be just making excuses. ;)

And to show that I'm not just picking a fight, the worst thing for me, when commuting by bike five days a week, half-an-hour each way, was how tired I was when I arrived home on Friday. It really took a lot out of me. Wasn't until Sunday morning that the spring was back in my step. Then again, after racing for years, I can't just ride my bike. If I'm in the saddle, I'm full out. Can't help it. You might be better off in that respect.
