When you ride a bicycle at full speed and the bike stops suddenly Why do you have to push hard on the handlebars to keep from flying forward?

Cars & Vehicles

It's called inertia, or conservation of energy. Basically it means that an object that is moving likes to keep moving, and that an object at rest likes to remain at rest. When you're on the bike you are that moving object that would like to remain moving, so to resist that force you have to brace your arms against the bars. The bike willthen transfer that force through the for and wheel and into the ground.
