I've shopping around for a bike because I started commuting to work about a month ago after my car was totaled. At first I started walking to work, but that just took too long and I don't like waiting for the bus. So I had my old Magna Excitor that is about 6-7 years old, so I figured I would try it. Soon I found that I really like commuting on the bike and when I have extra time I go to the park trail (asphalt) and back home. So I ride anywhere from 4-8 miles daily, I could do more if I find a decent bike. The bike I have can ride but the brakes are really bad and the wheels are crooked, so it is time to get something decent.

I looked up different models and this forum turned up on most searches, so I decided to sign up. I got my eye on a trek 7.5 FX (17.5") from 2007, but I'm not sure if it's my size. I'm also open to suggestions. I'm considering either a hybrid or a road bike that can take on sidewalks and asphalt trails. On my way to work I ride the sidewalk because I don't feel safe on the road. I did ride the road for a short distance and I noticed the bike is much faster on it. Anyway right now I'm using the Excitor 24" with the seat all the way to the bottom. I'm between 5' 4.5" and 5' 5" and around 135 lbs. I'm looking for a used bike online at the moment. I'm either going to pay with funds or try to trade my canon hf11 for it. My budget is a maximum of $500, which is why I'm considering something older in decent condition. Any help on the size or bike suggestions would help, thanks.
