The ultimate guide to bike sizes: road, MTB, gravel and hybrid sizes explained

One of the most important things to get right when choosing a new bike is the frame size. Although there’s a lot you can adjust on a bike so that it fits better, if you start off with a frame that’s too small or too large for you, you may be placed awkwardly and uncomfortable as you ride.

That can result in aches and pains when cycling and your bike not handling as it should, both of which can have a negative impact on your enjoyment.
