Bicycle problems
Hi. I have a bicycle thats second hand. Now, it was running all fine, no problems. Then, my friend decided to pump the tyres (when it was read with the pressure gauge, it was low). Anyway, it was pumped. And after that, stuff started happening. First there started to be some clicking or sound from the back part (but this is not a big problem for me). The worst is that when I ride it, like 10 seconds after, it suddenly becomes a lot heavier to pedal, and it feels like something is pulling the bicycle from the back, and it makes a sound like a motorcycle engine or engine when I keep on riding it. I'm not sure at all whats happening. Especially because it happens a while AFTER i start riding, not directly. Is it because maybe it was pumped too much? (I have to check the psi on the tyre later and planning to deflate it a bit next week). Other parts seem to be working fine since before. The problem came ever since it got pumped.

There could be a multitude of different issues casing the additional resistance, and it's really hard to diagnose them based on your description. That said, it's unlikely that pumping the tires is the issue. Is a brake rubbing? When you are not riding, do the wheels turn freely/easily? Do the cranks turn freely/easily? Do the pedals spin freely/easily? It you don't have the knowledge to be able to identify where the issues are actually occurring, it might be worthwhile to take the bike to a proper bike shop and have them help you get things sorted out.

From the description, I suspect that the wheel is slightly loose and one side is being pulled forward by the chain. The noise is likely the tire rubbing against the frame.

OP: welcome to Bike Forums.
Photos of the rear of the bike (from both sides), the rear brake, and the crankset would help greatly in diagnosis. If there are any new or strange scuff marks on the rear rim or tire, a photo of those would also help.
Although you can't insert images into comments or post URLs until you have 10+ posts (anti-spam measure that works pretty well), you can upload photos to a personal album you create in your User Profile. If you do that and let us know here, someone will almost certainly post the photos on your behalf ("pic assist").

Tires too big? Bearings too loose or tight? Badly needs grease? Brakes offset?

From the way I read it, the cycle of 10 seconds of good riding followed by bad riding happens every time he gets on the bike.
Also worth noting that any used bike, especially one that sat for awhile, can potentially have a period of mechanical issues until you work out all the kinks.

Do you have any other information? A name brand, a product name, the type of parts.
Used bikes usually work just fine with oiling the chain and lubricant to various pivots, leading up to regreasing the bearings for complete rebuild.
