Flybikes Neutron Intended for medium sized riders

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 Neutron is a BMX bike that is aimed at the midrange rider. With a top tube of 20.6” and a chainstay of 13.2” the Neutron meets the mark in the middle. The frame is made from ultra durable 4130 Chromoly tubing. The 1 1/8” integrated headtube is also drilled for gyro tabs. The Neutron frame also features removable brake mounts.

The Neutron has a great build kit on it as well. The 8.25” Chromoly handlebars bring your stance up at a comfortable position. The 1 1/8” Chromoly fork has a 27mm offset to bring out the wheelbase a bit and increase stability. Flybikes has set the Neutron 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 Neutron is a fantastic build and is great for all levels of BMX riding.
