Mountain Bike Sizing Guide

Mountain Bikes tend to use the T-Shirt sizing of S, M, L etc. or will have the seat tube measurement in INCHES. Why mountain bikes are inches and road bikes are CM who knows, but the part of the frame being measured is the same.

As a rule of thumb if you can identify your size as Medium on one brand, you should use that as a starting point on another brand too.

If you already own a medium mountain bike for example and are comfortable with the sizing, start there.

What is your height? Your suggested bicycle size
Feet/Inches Centimetres Suggested Size
4'10" - 5'2" 148cm - 158cm X-Small (14-15")
5'2" - 5'6" 158cm - 168cm Small (15.5-17")
5'6" - 5'10" 168cm - 178cm Medium (17.5-18")
5'10" - 6'1" 178cm - 185cm Large (18.5-20")
6'1" - 6'4" 185cm - 193cm X-Large (20.5-22")
6'4" - 6'6" 193cm - 198cm XX-Large (22.5"+)

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
