OK - I'm a new kid, and see there are a lot of 'Im new help me' posts on here - but I have another 'new guy' question if ya'll don't mind.
I've been running/racing (on foot!) since I was in 7th grade ... but my knees aren't doing too well with this and I'm hoping to do something a little less impact - so I decided to pick up a bike and start riding!
What I don't really understand is what type of bike I want. I know what I wand to do - but it seems like most of the manufacturer's websites seperate things in to mountain, bike, or leisure (among the competitive categories).
Well - all I want to do is get some excercise, so something preferably pretty quick ... but also be able to take it on some light trails if I wanted to - no drops or anything just like a path in the woods or something (not even rocky). Ultimately the bike might be used for commuting (I'm moving soon, but not sure where yet) so something for around town would be good - but not a priority at all.
So from my limited experience, I am thinking between these bikes:
Trek 7500 FX
Do these three even fit what I'm looking for? Am I missing the point of classifying bikes the way they are?
