Mountain Bike Sizing Guide

Mountain Bike Sizing Guide

Choosing the correct frame size when buying a Mountain Bike is essential so you feel comfortable and ensure you are pedalling in the most efficient manner. Along with choosing the correctly sized bicycle, having it set up correctly will also make the bike feel better and in turn will make it easier to handle. Sizing is very personal so please accept the information below as an approximate guide. Everybody is different and has different preferences so we would always recommend sitting on a bike before you purchase but accept this is not always possible. The guide we have created is based on over 30 years of experience sizing people on bikes and we are confident that for 95% of people it will indicate the correct sized bicycle for you.

There are many theories regarding bicycle sizing and set up, however for most cyclist's the following guide will give you an ideal starting point to be able to choose the correct frame size for your height and or inside leg measurement.

  • 26", 27.5" (650B) and 29" Hard Tail Mountain Bikes
  • 4' 10" – 5' 00" (Inside Leg Measurement 26" – 28") = 13" or 14" Frame
  • 5' 00" – 5' 03" (Inside Leg Measurement 27" – 29") = 14" or 15" Frame
  • 5' 04" – 5' 07" (Inside Leg Measurement 28" – 30") = 16" or 17" Frame
  • 5' 08" – 5' 09" (Inside Leg Measurement 29" – 31") = 18" or 19" Frame
