Why Can U Exert A Greater Force On The Pedals Of A Bicycle If U Pull Up On The Handlebars?

You might find your answer in Newton's Third Law. For every action there is an equal and opposite reaction. So when you push down on the pedal, some of the down force is also redirected up causing you to lift slightly off the seat. That is why people on bicycles look like they are going slightly up and down as they pedal. If you firmly grip the handlebars, you will generally create a more solid form and less of the downforce will be lost.
Because pulling on the handlebars adds more downward force to the pedals than your legs alone can produce. You're helping your legs out that way; think of pushing a door (that someone is blocking from the other side) with just your arms versus leaning and using your arms and legs
