Levers consist of a rigid bar or beam that pivots on a fixed point called a fulcrum. They are used to amplify force or transmit motion. Levers are divided into three classes based on the relative positions of the input force, output force, and fulcrum.
Some examples of first-class levers you might find in your house are a seesaw, a pair of scissors, or a crowbar. These simple machines consist of a pivot point, a load, and an effort force applied to move the load.
Levers are simple machines that help to lift or move objects by applying force at a certain point called the fulcrum. Pulleys are also simple machines that consist of a wheel with a groove and a rope or belt wrapped around it, used to lift or pull heavy objects with less effort.
The characteristics that distinguish levers from other classes of simple machines are that they consist of a rigid bar or beam that rotates around a fixed point called a fulcrum, they are used to amplify force or change the direction of a force, and they are categorized into three classes based on the relative positions of the input force, output force, and fulcrum.
Levers are grouped into three classes based on the relative position of the effort, load, and fulcrum. Class 1 levers have the effort and load on opposite sides of the fulcrum, Class 2 levers have the load between the effort and fulcrum, and Class 3 levers have the effort between the load and fulcrum.
Levers are classified by where the fulcrum is located.

Yes. A bike will have several levers. The crank arms are levers, the brake levers are levers, the shifters are levers, the handle bar is a lever.

yes They do have levers
There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.

why are levers useful
Brake levers and gear levers. The pedals are also a sort of lever.
