I chose this bike because my son likes to do tricks at the skate park and that is what this bike is mainly for. Hopefully he loves it!

Trail and street riding. I'm partial to GT bikes.

I know you have specific bikes for racing on this site. But I am thinking about racing BMX and at the same time I have a skate park in my neighborhood, so I was wondering if can race this bike. I also noticed that there is only a 3 pound difference between this bike and some of the racing bikes?
Rhett P on Sep 29, 2013
Best Answer: yes racing bike are meant for racing. so they are made of 6061 aluminum most of the time. They also have thinner materials for the bars and forks. The GT Fly is meant for skatepark use and light street. So its made of a thicker steel. You could go ahead and race on this bike. It wouldn't be the most ideal bike for racing. There really is not a cross over bike for the two. Racing bikes are designed for racing and dj/skatepark bikes are designed for dj/skatepark use.

Is the GT fly fast when you pedal? Do your legs get tired fast on it like some bikes? Do you know any websites where you can customize a GT?
A shopper on Oct 10, 2013
Best Answer: The GT fly bike will go as fast as you can pedal. It comes with a 25/9 drive train setup so its not really built for top end speed. Your legs tiring out from riding this bike is dependent on your conditioning and has nothing to do with the bike itself. there are no websites to try and customize a gt but you can go to the following link and change the colors on the bike to see how it would like with different parts
