Complete Bike Sizing

When it comes to choosing the right BMX there's loads of options to pick from, like colours and parts, but over everything you want to make sure that you've got the right sized bike for you, so we've created this quick guide to make it as easy as possible.

BMX Bikes are generally measured in 2 ways, the size of the wheel and the length of frame. 20" is the standard BMX wheel size but there are plenty of variations out there from 12" all the way up to 26"! The second measurement is the length of the frame, and this is worked out by measuring the length of the top tube. Frames tend to come in all manners of lengths and this is where you can really dial in the feel of your bike.

Check below for our guide on which bike is best suited to which age and height range, and please note that some of the sizes and ages will overlap, this is due to personal preference also being a big factor when choosing the right sized bike for you. We can recommend the size that we think will be correct, but only you can choose the perfect fit.

Wheel Size (in)	TT Length (in)	Rider Height (ft)	Rider Height (cm)	Rider Age
Balance Bike	Balance Bike	< 3'	< 90cm	< 3 years
12"	12"	2' - 3'	60cm - 90cm	< 4 years
14"	14"	2' 8" - 3' 4"	80cm - 100cm	2-5 years
16"	16"	3' 0" - 3' 8"	91cm - 111cm	3-7 years
18"	18"	3' 6" - 5' 0"	106cm - 152cm	6-11 years
20"	18.5" - 20.5"	4' 2" - 5' 4"	127cm - 162cm	10+ years
20"	20.5" - 21"	5' 2" - 6' 4"	157cm - 193cm	11+

*TT = Top Tube

Now as mentioned all of the above sizing is approximate to what we recommend based on each size. You might prefer having a longer or smaller top tube than what is listed above based on your preferred style of riding, and that is perfectly fine, after all it is freestyle!
