Fork -> Body
Didn't know what other title to give this thread.
I have a used bike and I don't think I got it with the original fork. As you can see in the picture, there is a gap between the fork and the body of the bike. It works fine, but it looks strange so I was wondering if I'm missing a piece between the two.

What you refer to as the "body" is commonly known as the "head tube".
If it was me, I'd pull that apart to see if there are two crown races on top of each other.
That would explain the gap nicely.

I would pull the fork out and make sure
1- The crown race is fully seated.
2- There is only one crown race.
3- The crown race, bearing, and headset cup (the part in the frame) all fit together well. Being a used bike/fork, there is always a chance that someone put in a new fork with the wrong crown race for the headset.

I see the fork crown race seat as being "open" as in there's no headset race seated down all the way. Why is yet to be known. Do what the others have suggested before you ride this bike.
And look at the rest of the bike for other safety issues. It's obvious to me that someone who doesn't know what they are doing was worked on this bike. What you don't know can still kill you. Andy

Since the OP is referring to the frame (or more specifically the head tube) as the "body" I think suggesting they investigate this themselves is very poor advice.
Take this to a knowledgeable mechanic and have them look at it. If you have a friend that knows bikes they can take it apart and show you how it works.

Here is a great intro on headsets: https://www.sheldonbrown.com/headsets.html
I have never seen two crown races installed on a fork and suspect this bike has a strangely shaped headtube and this is normal. Or, more likely, something has been installed upside down.

You can have more then enough mechanical competency to work on a bike (including what the OP is looking at) and not know what some of the parts are called (in this case the head tube).

Would you trust a doctor who couldn't refer to body parts with their "proper" names? How about a lawyer that can't read a document because it uses terms that they don't know? Having said that...
I have all kinds of empathy for those who can't spell, don't read or write well. (and while I disliked the politics of the first George Bush and would never trust Dan Quale to take over it wasn't because of his spelling challenges) I suffer from this, spent years in special speech classes and live by this computer's spell check. Some might see this in how I write replies here. BUT I do try to get grammar and spelling correct best I can. It's when one takes their "style" and places it before the public that this becomes a concern for many. I mentioned a similar type of concern but with the person who assembled the headset as the worry, not the OP. Andy

Regarding the OP's subsequent comments. OK give it ago yourself. Plenty of youtube videos and online text stuff to get anyone throughj a head tube/ headset issue. But maybe I'm too prideful, but when I post questions and don't know the parts I'm referring to, I try to educate myself at least that much before posting. I have indeed looked for names of bike parts before trying to ask a question. Not only do I feel better (like i said, pride), but prober nomenclature is a real benefit to communicating well. That's why every profession has jargon. In this case it would have helped greatly in that the thread title would have been understandable.

My experience with working on a headset for the first time showed me that they are not all that difficult, and I am far from being an experienced, knowledgeable person with good mechanical aptitude. I found that getting the right tools certainly makes it easier, but still doable with self made or alternate tools that can and do work. Youtube videos, like RJ the Bike Guy, and Park Tools are informative and actually let you see what you are trying to accomplish. Certainly, some of the videos are not so good or informative. Of course, making sure you know the proper type and specs for a BB that is compatible with your BB shell and crank set is of utmost importance. All the styles and sizes that are now used can be a bit confusing. Good quality, sealed bearing cartridges make it easier to replace the bearings if the proper one is being used. I do now have a headset cup removal tool and a headset press. Both are lower cost versions from online dealers branded with their name.
It can be helpful to take pictures and notes while removing and installing the headset/bearings, so you are not going just on memory or using what you perceive to likely be correct. Take your time, check a video again if necessary, make sure to do a thorough inspection before riding the bike. One other note of help, I have a good relationship with the LBS I frequent, ergo, asking questions or having them look at something is okay with them. I never look to get something for free, but it does happen, I then make my appreciation known in someway.
As for knowing the proper terms, it does simplify the communication and helps those that are willing to help you. Much of that just comes from experience and information from others. I think most members that comment on wrong terminology are truly trying to help. At times, some just need a way to ego build and feel superior. Pretty sure most humans are sometimes guilty of that.
