I currently own a Joker 05 Diamond Back. I bought this bike like 2 years ago and owned it for about a year without getting into the whole BMX thing. The next year I saw a you tube video on flatland and got interested so i started learning the basics etc and now I am intermediate at flatland I guess. Anyways my question is whether I should stick with this bike or buy a new one? What are some intermediate bikes? Is Diamond Back a good brand because I didn't really know anything about bikes when I was buying this one. I just saw a nice looking one and got it.
