GT Mach One 20 U Junior Yellow

The GT Mach One Junior BMX Bike was designed and built as an affordable way of getting more riders into the sport without costing an arm and a leg.

A 6061 alloy frame paired with hi-ten steel forks and bars give this mini machine all the strength and rigidity it'll need to get those younger riders learning and progressing at a consistent pace.

The Mach One Junior BMX Bike is fitted with plenty of race ready parts.
