Mach One Junior

Information from: http://www.gtbicycles.com/bikes/bmx/utility/2011-mach-one-junior.

You don't need to be a serious BMX racer to appreciate a GT bike. That's exactly what the Mach One series is for. It's built for a little bit of everything, but still has the feel of a genuine GT. Hit the track for a lap. Hit a jump on they way to school. Hit on the gal next door as you roll on by, and look cool all the while. There's lots of different ways to earn your wings on a Mach One.
