What simple machine to build a jump for your bike?

To build a jump for your bike, you can use a lever as a simple machine. A lever is a rigid bar that pivots around a fixed point, called a fulcrum. By placing a ramp at an angle and using the lever action of your bike hitting the ramp, you can create a jump. The force exerted by your bike on the ramp allows you to propel into the air, demonstrating the principles of mechanical advantage and energy transfer.
