from home (crown hill) to school (downtown) 7.5 miles.
Bus is about 40 minutes from when I step onto it, but the wait at the stop can be as long as 20 minutes.
Express bus is 25 minutes.
Car is 20+parking+walking=35 (not to mention the cost)
Bike is 35 min

On the way there (which has a decent downhill down 15th street) I have made it in 20 minutes, leaving my house and getting to class on time. Fastest I've ever ridden and I hit all the lights green.

Unless I have a flat tire or need to carry something large that absolutely can't be exposed to the weather or need to dress up for a presentation I bike, far more enjoyable and just as fast, all things considered.
