What is the similarities of a bicycle and a car?

bicycle is a vehicle usually with two wheels and a car is a vehicle with four wheels......

Additional answer

Always with two wheels. The definition of bicycle is a two-wheeled vehicle. If it has more or less than 2 wheels then it's not a bicycle.
A car is motorized and a bicycle is not. A bicycle saves energy. Of course, a 'motor' or 'electric' bicycle can be powered. Fundamentally a 'bicycle' has two wheels and a car has more (usually four).
