PROTON is a street BMX Bike that also feels great on ramps. This new design includes a complete CrMo frame and our cone shaped forks, these two together make a perfect combination in the brilliant Gloss Black colour option.
This version of our PROTON Freecoaster bike is defined by the 4-piece bars, for those who prefer its classic look.
Though you can’t see it in the picture, the PROTON BMX includes our removable Springhanger brake system, as well as all the aftermarket parts you can see, included in our Devon, Fuego and Trebol series, with polished finish hubs in this model.
So, if you have already chosen the colour and the bars design you prefer, there is only one thing left to do: choosing the RHD or LHD version, according to your main grind direction.
And remember that with your BMX order you will also enjoy all the Flybikes’ shipping benefits:
• 100% plastic-free recyclable packaging
• Easy Assembly

PROTON BMX is available in Flat Metallic Red and Gloss Black, Freecoaster or Cassette.
