  • 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 ) Wheel Size (in)  Top Tube Length (in)

    Nice bike, fast delivery.

    We bought a bike for our son's birthday. I made an order late in the evening and in the morning I received a trace number. Next day bike arrived to our house. On birthday we assembled bike. It was easy enough. My son goes to BMX race, so he has BMX race bike. He wanted BMX freestyle bike to make tricks. He is very happy and likes his new bike.

    Good quality bike but instructions are confusing

    Very smooth, Light, Fast and Reliable. Only problems were instructions are somewhat challenging and there no instructions for the brakes if you put them on. But overall good bmx bike for kids/ teens

    Fantastic customer service - thank you

    I ordered the jet bmx over the weekend, it was dispatched on Monday and arrived on Tuesday, so a massive thank to all the team at Sourcebmx for such fantastic customer service and getting the bike to us so quickly. When it arrived and was assembled my son was absolutely thrilled as it’s a great bike to ride and he has been getting lots of compliments from his friends about it (he likes that bit too!) . So if you’re thinking of getting this bike from Source, I’d definitely say to go for it!
