I’m a junior in high school, and I live a little under 4 miles from my school. I plan on riding a bike to school, but I have a huge mountain bike.

Should a ‘beginner’ cyclist get a road bike? I’m not very good at cycling; mainly I’m afraid of sharing the road with cars and also tend to overreact to potholes and cracks in the ground. I’m also pretty weak on climbing. On the other hand, it’s my objective to overcome these obstacles and eventually be able to ride long city trails. Should I start with a mountain bike and build up my skills first, or should I just go ahead and get a road bike since that’s my end goal anyway?

I have a 26" Mens’ NEXT PowerX Dual-Suspension Mountain Bike that I purchased online at Wal-Mart. I took for a ride the other week and was fine and got it out the other day and for some reason it seems like it wants to shift gears or at least I think that is what it is doing but not sure. I just hear a clicking sound down around the chain and not sure what it is? Does anyone have any suggestions?
