OS 20" BMX Freestyle Kolo

Old-school x New-school mashup

The OS 20" by Mafia bikes is heavily inspired by the old-school cool 80's bike designs but features a healthy amount of new school parts as well. The OS 20" is meant for nostalgic parents who want a piece of the pie while looking over their child at the skate park.
