It is generally easier to pull a roller other than push it in Physics. The rollers beneath it usually reduce the friction.
Whether it's easier to pull than to push depends on the circumstances, there is no universal principle here. If you're using the pulley suspended above you can add your weight to your arms force and thus amplify your effort(pushing a rope doesn't produce any result of course). If you were to move a heavy stone block it might be easier to push it, if there's no grip possible to pull.
You would need more force to push a wheelbarrow across a dirt road than a wood floor because of the friction created between the dirt road and the wheelbarrow wheels.
Regardless of the physics to this answer, The Safety Short - Push vs. Pull - describes ways we can protect ourselves by choosing to push instead of pull whenever we can, ie) Physics aside, its safer to push and object rather than pull it.i think its easy to pull an object but that's just my thought
Essentially you're looking at F = ma acceleration, a = the same for both vehicles. The mass, m of a bike is much less than that of a car therefore; The required force to push a bike is much less than that required for a car. Therefore it's easier to push a bike.

You need more force to push it. The loaded one has more mass than the empty one.
The wheelbarrow was a very important, useful invention. Wheelbarrows distributed the weight of the load between the user and the wheelbarrow itself, allowing the user to bring more of a load than they would've without it. Ancient Chinese wheelbarrows had one wheel in the middle, so it could navigate and balance easier than a two-wheeled wheelbarrow could while still carrying the same amount.
I have always known that the pull force is greater! Its as if Earth's gravity it pulls inward it can't push out. Therefore the pull is a greater force, and I may be corrected if I am wrong. I have always known the pull is the greater force
Liquids are easier to move around more.
Depends on the person and configuration. In general, you can push more than you can pull, because to pull you are limited to some proportion of your body weight, whereas when pushing you can use the pushed mass to increase your traction.

Gravity and the weight of the door assist in making it easier to pull down than to pull up.
Well - the obvious answer is - because a car weighs less than a bus !
