Correct Bicycle Size
Riding a bicycle that is not correctly sized to the rider may result
in the rider’s feet not being able to touch the ground and
balance the bicycle, properly reach the handlebar for steering or
braking, and loss of control when pedaling
Use the wheel size in the following table as a guide to match the
rider and bicycle.
For example, bicycles with a wheel size of 12
inches fit a rider that is 28 to 38 inches tall. Note: Some bicycles
such as folding bicycles may have smaller wheels but still fit
adults
If the bicycle has a top tube on the frame, check that there is
one to three inches of clearance between the rider and the top
tube
