Description
The Radio Astron is a park-focused 20" BMX for riders who like a quick, responsive bike that is ready for technical skatepark riding straight out of the box.
A full chromoly frame, lower standover and rotor setup give it the right foundation for spins, airs and brake-assisted tricks without turning the bike into a tank.
