Mafia Gusta 18 inch BMX Bike - RedThe new Gusta model is exactly what you would expect from a mafia! Just as badass as the 20 BMXs but for the younger riders that will benefit from a smaller, tighter and lighter bike. The Gusta is decked out with the same bullet proof parts as our bigger 20 bikes and coupled with its responsive geometry it really is one of the best completes on the market for the price and size.
