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 t a rider that is 28 to 38 inches tall. Note: Some bicycles 
such as folding bicycles may have smaller wheels but sll t 
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. Figure 1.1
Inability to safely reach the handlebars and dismount the 
bicycle may result in loss of control of the bicycle. If the 
bicycle has a top tube on the frame, ensure there is one to 
three inches of clearance between the rider and the top tube. 
Improper setup or maintenance of the bicycle may result in  
an unexpected movement, loss of control, and serious injury  
or death.
