In this picture the shock looks like a black blob and I can't even make out the lettering on the bike frame.

No idea what kind of shock that is but you better raise that seatpost before you start breaking stuff.

Well, it looks like a black blob because it seems it really is just a black blob.

Seat post, hell. It looks like the sag alone would crash the upper link into the truncated seat tube. Unless the linkage is split up there, so the seat tube passes between the arms.

Equipment like this doesn't have a brand. It just comes from secret sources known only in China.

It is a Black Blob, best shock you can get for $0.30. More quality than using a toilet paper roll but less quality than a hard dog doo.

Then you are likely out of luck getting any help on the ID. Heck, I canít even make out the brand of the bike.

Update:
Maybe that's an useless information but i'm going to post it anyways in case anyone need it.
The shock looks like both air suspension and coil , but in fact is just a coil shock with a sort of protection (maybe againsts mud and water). I Assembled the bike from zero and i had to admit that protection was worth since is the first time i found a still working cheap-coil shock for those types of bikes.
Even the fork had to be disassebled and cleared vut this shock was still fresh.

Is there an arrow stamped on the disc brake rotor?
If there is, it points to the direction that it rotates.
The 'arms' on rotors are usually facing the other way around.

I can offer no advice other than to cruise the aliexpress / auction site pages. what actually is wrong with it?

Anyway, I love the bike rack in terms of originality, although I not sure how they used it in practice

BTW - how heavy is it? I was given a similar kind of bike and it weighs a ton...

I've scraped out hundreds of bsos with "shocks" and taken a bunch apart to see what is inside. They aren't shock absorbers in the automobile use of the word. The black blob version has a plastic cover over the coil spring. Other wise it's the same as all the other bso "shocks". Just a shaft inside a couple of plastic sliders to keep it aligned with a rubber washer to dull the slamming at the end of the travel. There is no dampening effect like a real shock absorber. The outer body is threaded with a large nut to adjust the preload on the spring. They are mounted with plastic spacers, a through bolt and nut. It takes two 5mm hex wrenches to remove.

A real shock will have air compression with oil dampening through calibrated or adjustable valves and cost more than the op's bike.

Shocks come in different lengths and those with coil springs, the springs come in different weight ratings. Because of the angles in the various suspension designs, the coil weight ratings don't correspond to body weight.

Bolt in a couple pieces of angle iron and a bushing and make it a hardtail. It might even handle better in corners that way.

Yes the photo I posted is a correctly attached rotor.

I mentioned the orientation of the rotor because the OP said 'I Assembled the bike from zero' and the rotor is incorrectly attached in the OP's photo in the first post.

Misunderstood. Yes, the rotor is correctly oriented. No, OP did not make a mistake mounting the rotor. Sorry.

I once got a Cannondale Super V that had a piece of pipe in place of the shock. A more elegant method. Used the same shock mounting bolts. No sharp edges sticking out. Cut and drill to get the height of the bike where you want it. it took a while to find a suitable shock and flip the bike.
