Gravity
Raising the front wheels of a car or bike while in motion, so that the car or bike only have the back wheels on the ground.
Friction causes the bike to slow down.
Cobalt wheels are used on bikes. These cobalt wheels are much stronger that the usual ones when you buy your bike. They can stand more force, incase you should fall with your bike, the won't bend or break that easily.
There are different sizes for dirt bike wheels as there are for regular bike wheels.
The force of Gravity. Gravity is the force that pulls everything down to the ground. Hope this helps!
Thin wheels alone isn't enough to identify the bike type. Can be a road bike, bike, a track bike, a TT bike. Even fixies and single-speeds can have thin wheels.
The wheels are the big round things on which the bike moves and the axles are at the center of the wheels, attaching them to the bike.
The wheels against the ground, the axles against the wheels, the chain against the axles, the pedals against the chain, and your feet against the pedals.
Friction. There is less friction between your bike tire and the ground when it's wet, increasing the stop time.
Change the wheels with specil ski wheels i think its called ski bike.
Applied force, normal force and friction. Your weight applies a downward force, and the two wheels touch the ground (contact force) and produce a reaction force (according to newton's third law), and ofcourse there is friction which opposes the motion of the bicycle.

When you ride a bicycle, the force of the wheel against the earth causes the earth to push back on the wheel, propelling the bike forward, according to Newton's law of equal and opposite reactions. If the force exerted by the earth is strong enough, it can overcome the inertia of the bike.
