Radio Helium Cruiser 24w 2021 - BMX Bike
A bike which has developed quite the following, we’re stoked to see the return of the Helium cruiser to the 2021 line-up. Taking our aftermarket helium cruiser frame and injecting it with a full pro parts package, we spared no details here. From forged dropouts with chain tensioners, our very own aftermarket argon pro rims to parts from Promax and Tioga, this 24″ machine is a bike with no limits.
