That'd be a quadricycle or a quadra bike or something like that. Maybe even a pedal car.
Since the rider pushes down on the bicycle seat (as a result of his weight), it follows that the bicycle seat pushes back up, since forces always come in pairs. Note that if the seat DIDN'T push up, the force of gravity on the rider would make him move downwards.
To provide some rest and support during riding.
If you sit on it, you push downward. The bicycle seat naturally pushes back up - if this wasn't the case, you would accelerate downward, due to the force of gravity.
The penny farthing is a type of bicycle. The bicycle has a large front wheel with a seat on top and a tiny back wheel. The bicycle was invented by Eugene Meyer. The bicycle was invented because the larger wheel meant higher speeds by which the cyclist could travel.
Simple machines are things that change the direction or magnitude of a force. A bicycle saddle doesn't do that, so no.
The seat of the bicycle is at the backside and not in front because it it easier to ride it and takes less effort from this point.
A banana seat is an elongated seat on a lowrider bicycle, which curves upwards at the rear.
A female bicycle have bigger seat than the male bicycle. That's how you know the difference.
A bicycle seat is typically called a saddle.
That's a tandem.
