  • From their Expert level range of the bikes, the Stay Strong Optimum PRK BMX Bike is spec'd out as a skatepark ride but it ultimately at home on any terrain.

    It boasts popular frame geometry and parts which include tapered forks with chromoly steer tube, double wall rims, chromoly 3-piece cranks and fully sealed bearing throughout so the PRK really doesn't disappoint.

    Removable tabs on the frame make fitting a gyro a breeze, 25/9t gearing gives greater clearance at the skatepark and lightweight parts like the nylon pedals & combo seat/post make this bike easier to manoeuvre and nail those tricks!

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 which we have also simplified for you into XS, Small, Medium etc categories.

Below is a guide to what size you should be looking for. note there is some overlap in sizes as personal preference also comes into the equation.
