If you are considering buying a bike, it is vital that  you find the right size bike for you, so this handy guide has been produced to  help when you make your purchase. Here at Machine Mart, we have a wide range of  Hybrid, urban/city, mountain and road bikes in various sizes, so we are sure to  have something to suit your requirements.    

Choosing  the right size
  For safety and comfort reasons, ensuring you choose the  right size bike for you is vital and should be very easy. Follow the advice  below and finding the perfect bike will be a simple and rewarding task!

 
       
  • The quoted size of an adult bike is usually  measured from the top of the seat tube (where the seat slots into the frame),  down to the centre of the bottom of the bracket axle (where the pedal cranks  are carried).
  •    
  • Your feet should be able to touch the ground  on tip-toes when sat comfortably on the saddle and the handlebars should be  within a comfortable reaching distance. Ideally you should visit your local Machine Mart store to  try a bike for size.
  •    
  • Sometimes, with certain types of bike, a  smaller frame with a raised saddle might be more suitable and worth considering  to provide a more comfortable reach.

Machine  Mart Recommends
  We recommend you consider the sizing charts provided when choosing your bike. They give a guide to frame sizes  against rider height - Simply find your height on the charts, then check which  size of frame you need depending on the type of bike you are interested in.
  You should always be sure of what size bike you require  and although the sizing chart below and advice above are excellent guidelines,  we strongly recommend that you visit your local Machine Mart store to  try out the bikes on display to find the right one for you.
