Ruption Motion BMX Bike

The Motion BMX Bike features all the same great spec as Ruption's Hacker model, but with the addition of a sealed integrated headset and a 4130 CrMo downtube for extra strength. Also, a slightly longer 20.75" top tube makes the Motion ideal for taller or more experienced riders to get their shred on at the skatepark.
