Why do bicycles benefit from having larger wheels when going up a bump as shown in the picture? <br/>
Assume that for both bicycles:<br/>
1.)	The tires have equal air pressure.<br/>
2.)	The bicycles never leave the contact with the bump.<br/>
3.)	The bicycles have the same mass. The bicycle tires (regardless of size) have the same mass.<br/>

            <p>The bicycles with larger wheels have more time to go over the bump. This decreases the magnitude of the force needed to lift the bicycle.</p>
