The Final Say on Mountain Bike Wheel Size! All you need to know about wheel sizes and what size is right for you.
First ask yourself honestly how many mtbs you want at any given time. Can you afford one mountain bike, two bikes (a downhill bike and an xc bike), or three bikes, (a xc bike, an enduro/all mtn bike and a downhill bike), four bikes (a xc bike, an enduro/all mtn bike, a dirt jumper and a downhill bike) or five bikes, (a fat bike, xc bike, an enduro/all mtn bike, a dirt jumper and a downhill bike)?
Then ask yourself what you want to do on each bike as your answer/s will differ greatly if you can afford multiple bikes.
How tall are you? Height is a big factor ......
