How is friction used when riding a bike?

Friction is effectively used when riding a bike once it starts to brake. Friction is applied on the brakes to the tires so then it will effectively slow down until you put it on a stop, or if you just want to slow it down for a desirable and appropriate amount of speed based on the current situation as you ride the bike on the road.

Friction is used when riding a bike when the brakes are used because when the bike stops there is friction between the tire and the floor it automatically makes you stop when the break is triggered
