My son is 10 years old and has discovered BMX. He is having a great time and cannot get enough of it. I am trying to figure this whole bike thing out and need some help! We have spent some time at the track and I have asked several people about the bikes their kids are on. It seems like Redline and intense are very popular. My son currently has a Redline raid but its not much of a race bike. He said on an Intense Expert XL and the fit looked pretty good.

I guess what I am asking is what should I be looking for in a bike. I have weeded through a bunch on internet info but would like some opinions since I look bikes on craigslist and came across this bike. Its older but it looks nice http://sandiego.craigslist.org/nsd/bik/2794702952.html Any opinions? Am I on the right track for my son?

Thanks!
