Flybikes is an innovative BMX brand based in Spain. From their conception in 1999, Flybikes have been developing and innovating new products. Out of love for their sport, Fly engineers new and exciting products for the BMX industry. From removable gyro tabs to invest casting of drop outs and more, Flybikes is at the forefront of BMX innovation.
The Flybikes Proton is a BMX bike that is aimed at the taller rider. With a top tube of 21”, seat stay of 8.5”, and a chainstay of 13.6” the Proton is a taller and more stable build. The frame is made from ultra durable 4130 Chromoly tubing. The 1 1/8” integrated headtube is also drilled for gyro tabs. The Proton frame also features removable brake mounts.
The Proton has a great build kit on it as well. The 8.5” high Chromoly handlebars support the frame’s already high up geometry. The 1 1/8” Chromoly fork has a 32mm offset to bring out the wheelbase a bit and increase stability. Flybikes has set the Proton up with a traditional 25T-9T drive train (gear ratio of 3.9). The rear 14mm cassette hub is sealed and has a 9T driver. Both rims are Flybikes Trebol 36h double-wall rims. The Flybikes Proton is a fantastic build and is great for all levels of BMX riding. The Proton is intended for the taller rider with the large frame and bars.
