Don't really know what you're after here...
The bicycle as a whole keeps moving due to something called inertia. Inertia means that an item prefers to keep doing what it was doing the moment before. If it was stationary it takes an effort to get it moving, if it's moving it takes an effort to stop it.
Unless you're heading downhill, or have a strong tailwind, in which case it's gravity or the tailwind that keeps you moving.
THe other posssible thing you're after is the one-way clutch thingy stuck in most rear wheels. Depending on bike it'scalled either a freewheel or a freehub, and it allows the pedals to hook on when pushed forward, and to disengage if the wheel is moving by itself.
Friction is what ultimately stops your bike
If the bike has a license, then it is an official vehicle and you need to ride it on the road and stop for the ambulance and get on the shoulder of the road.
You push the brake.
After an emergency stop on a bike, you need to start on a low note and low speed. You will keep accelerating as you gain momentum.
A lever on a bike, such as the brake lever, is used to actuate a mechanism that increases or decreases the friction needed to stop the bike. When the lever is squeezed or pulled, it applies pressure to the braking system, allowing the rider to slow down or stop the bike.
The purpose of the brake lever on a bike is to apply pressure to the brake pads, which then press against the wheel rims or discs to slow down or stop the bike. By squeezing the brake lever, the rider can control the amount of pressure applied to the brakes, allowing them to adjust their speed or come to a complete stop as needed. This helps the rider maintain control over the bike and stop safely.

Yes, pay what you owe on it.
Stop bike and get in car
THe brakes rarely need to stop. But the brakes can be used to make the bike stop.
Friction causes the bike to slow down.
To safely stop a bike without brakes, you can use your feet to gradually slow down by dragging them on the ground. Additionally, you can steer the bike in a zigzag pattern to reduce speed. It is important to plan ahead and give yourself plenty of time to stop.
