BMX bikes are typically based around 20in wheels, although other wheel sizes can be found on race bikes.
They feature a rigid frame and fork alongside high-rise handlebars and a single cassette gear.
Their relatively basic construction makes them robust as well as easy to maintain and understand.

The sport has two distinct genres – racing and freestyle. Racing is where it all began as far as BMX is concerned,
while freestyle evolved as a new breed of riders started specialising in tricks and bike handling as opposed to banging bars at the race track.
