FIT AND SAFETY

3.1Fit

Make sure the bike fits. A bike that’s too big or too small for the rider is harder to control and can be uncomfortable or dangerous.

Frame size.

Your dealer will have recommended the best frame size for you, based on the information provided. If you picked your own bike at the dealer shop, your dealer would have taken the time to fit you to the correct frame size at the time. If someone else selected the bike for you, as a gift, for example, it’s important for you to make sure that it fits before you ride it.

Standover height (see fig.9).

It is the distance from the ground to the top of the top tube at the point where your crotch would be if you were straddling the bike by standing half way between the saddle and the handlebar stem. To check, straddle the bike. If your crotch touches the frame, the bike is too big for you. A bike you ride only on-road should offer a minimum clearance between top tube and your crotch of 2.5 to 5 cm. (one to two inches).

A bike that you’ll ride off-road tracks should have 7.5 cm. (three inches) minimum clearance, whilst a mountain bike for use on tough terrain should offer 10 or more cm. (four or more inches) clearance.
