This year Fly did their homework and redesigned the Proton BMX Bike to make it better than ever in 2019, giving you even better value for your money with the freecoaster version. It all starts with the lightweight and durable Full CrMo frame and gets better from there. The two-piece steer tube fork has been upgraded to a hydroformed 1-piece steerer tube as durable and reliable forks are crucial for an unreal BMX ride. Fly have also upgraded parts across the board, with a brand new Trebol headset, Trebol cranks, durable 510 chain, taller standover height and bigger bars to not only improve the handling and feel, but also the look.
The smooth and fun ride is complemented by the Trebol 2.35” tyres and double wall rims. Fly have finished this bike off with some slick gear, with a Trebol Tripod seat, timeless Fly Devon grips and Ruben signature graphite pedals. The Proton BMX bike is built to give you high-performance spec on a budget, this versatile BMX bike can handle a wide variety of terrains, so you get plenty of bang for your buck and tear up straight out of the box.
