  • The Jet Block 20" is the most affordable full size 20" BMX we currently offer and a great entry level bike from Jet. Features include Hi Ten 20.25" top tube frame, 8" High steel bars, 3pc Forged cranks with sealed mid BB, 9t Sealed cassette hub, Padded seat & post combo & much more. It is unheard of to get 3-piece cranks and sealed hubs and bearings at this price point - all of these things mean the bike is lighter, stronger and harder wearing than parts normally found at this price.

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!
Rider Height (in) Rider Height (cm ) Top Tube Length (in) 
2FT - 3FT 60 - 90cm 11.5" - 13"
2'8" - 3'4" 80 - 100 cm 2.8" - 15"
3FT - 3'8" 90 - 110cm 14.5" - 17"
