Bike Size Guide
The hardest choice when buying a new bike online is choosing the correct size. Obviously it's not always possible to travel the country to test ride one, so here's a fool-proof guide, offering all the help and advice you need.
Riding Position
It's very important that you have the handlebars and saddle adjusted to the correct height to suit your needs. A recent survey suggests that 65% of cyclists do not ride in the correct position. The most important being the saddle and pedal arrangement as this can prevent injury, make riding easier and even eliminate chaffing.
The Highway Code states that all cyclists must be able to touch the floor when riding. Therefore, when looking for a general bike sizing guide, this is always a good place to start.
