It was a good idea. steering became easier when pedaling wasn't pushing the wheel back & forth, and it became easy to use a chain to get a better ratio between pedaling and speed.
You stir the paddles and the wheel start moving.

A bicycle fork is the portion of a bicycle that holds the front wheel and allows the rider to steer and balance the bicycle.

The front wheel is still in contact with the ground. As the rear wheel is pushing the bike forward, the fron wheel doesn't have much choice, either roll or slide. And usually it'll roll. When you peddle the chain spins round and pushes then u stop peddling but your back well is still moving so that makes your front well move wen your not pedaling
Because the rear wheel is doing the pushing and the front wheel is being pushed.

I think you looking for a bicycle called the Penny-farthing, an early design of bicycle that had a very large front wheel.It is called a penny-farthing. Called that because the difference between the big wheel and the small wheel was similar to the difference between the old British pre-decimal penny and the farthing.

Fork is the two-pronged thingy that holds the front wheel.
The main difference is that, while both rotate, the wheel has an additional translational movement. That is, the entire wheel moves forward.
