Fit 18" Misfit BMX Bike
Fit 18" Misfit BMX Bike
-
Taking input from their team riders and constantly manufacturing and testing new prototypes has kept all of the Misfit bikes ahead of the pack for years.
The foundation of the Misfit line up has always been dialed in geometry and dimensions that are well proportioned. To improve on the already popular 18” Misfit bike for 2026, Fit lightened up the frame and added a CNC machined Integrated headtube with threaded Gyro holes.
They also lightened up the fork and reduced the rake to 31mm while adding a welded insert for headset tensioning. With more and more 18” bikes hitting the streets the upgraded rear axle to a larger and wider 14mm X 170mm model allows for peg use.

BMX BIKE SIZE GUIDE
BMX bikes are measured in two ways: the size of the wheel (20” is the standard BMX wheel size), and the length of the frame which is gauged by the top tube measurement. We have also simplified for you into XS, Small, Medium, etc.Here is a guide to what size you should be looking for - note that there is some overlap in sizes, as personal preference also comes into the equation!
