Converted to a BMX Cruiser?

Can this bike be converted to a BMX Cruiser. What would I have to change?
Can I make the existing rear wheel a single speed by removing all the cogs but one and using some type of spacers (where would I get them) to replace them? Then use the smaller chain ring and remove the larger one? then BMX bars? it won't be a true bmx of course but it will be good enough I think to do a few obstacles at the local park? any assistance would be appreciated.

If it has a freehub then yeah, go with spacers. You can get "Singlespeed Kits" which have a bunch of spacers, possibly a new lockring, and a cog (sometimes several cogs.)

If you want to do a lot of hard pedalling, you'll want to get a cog carrier, or a nicer, thicker cog (like a Niner cogalicious or a Surly cassette cog. - thinner cassette cogs really chew into cassette bodies) Stock cassette cogs also tend to have pretty short teeth, so are more prone to chain dropping.

If it's a freewheel, some people do use spacers (PVC pipe cut to length), but I prefer to get a BMX freewheel, screw that on the wheel, then respace and redish the wheel. this can be a little tricky, so it can be easier to just buy a single speed freewheel rear wheel.

If the chainrings are bolted on, then you can get singlespeed chainring bolts or just use spacers to bolt on either the middle or big ring by itself, you can move to the outside or inside of the crankarms to adjust for chainline needs.

Careful picking out bars. Some BMX bars have a 22.2mm clamp diameter, whereas your stem has 25.4mm clamp diameter. Actually for true BMX bars, you'd also need to swap out the stem for one with a removable faceplate.

Single speed Freeheel MTB wheels can be built , the bars and stem can be replaced .

the part that may be a challenge for the less Mechanical is getting the crank and hub end of the chain in a suitable alignment.

then spindle lengths of BB need be chosen , and that is not something to be sorted out from this end of the game .

if you have a bunch of different BB spindles you can try them , yourself.

if the frame is vertical dropout the chain cannot be tightened , you need a separate tensioner ..
I canot see the drive side you sent a NDS picture.

a fixed one will make the chain bouncing off less likely , it may be coming off if you use an old RD as the tensioner .
(but that is cheaper)

If it does have vert drops, he can take the shifter cable from the shifter, using the barrel as a stop, and use it to lock the derailure to keep chainline. I did that once to help a guy convert his mtb to single speed, as a cheap alternative to one of those fauxrailure things.

Don't understand how you can have a "BMX cruiser"
BMXes are built for short bursts of high intensity riding, while cruisers are built for - well, cruising.

And unless you switch to a SS f/w and redish the rear wheel, your bike won't get any stronger.

It's a lot of work only to be able to remove chainrings and derailers.

You might as well ride it as is and see if it survives.

Bmx cruiser is like a clunker, normally a beach cruiser set up like a bmx bike, with a single speed/noncoaster brake, bmx bars, street(non B/C) tires, not a hard concept to get. Difference is a clunker is a down hill bike(mtb grand dady) with mtb parts(or at the time of conception; dirtbike parts).

In BMX racing, cruisers are 24" bikes. Proto-BMXers would often race on 20" Schwinn Stingrays or the like, so it would make sense that older kids would race on cruisers.

It's often called Cruiser Class.

Non-race 24s are also often called cruisers, and BMX 26ers are also often called cruisers.

Ooh, yeah, guess that's about 62 GI - 24x2" tires, 9x25 gearing. Pretty nice street cruising gear.

My rule of thumb for SSMTB on mellow trails is 2:1, but making sure to use an odd tooth count cog to go with the even chainring. 34x17, 36x17, 38x19. A little lower for trails with steepness.

At noon today I made the first purchase a 16 tooth single cog free wheel at the LBS for $12. . Then I purchsed a 44 tooth chain ring for a single speed track bike from Amazon for $29 as the LBS didn't have one in their shop. So i will pop those on this week and then do the bars and a new single speed chain. Will post pic when I'm done. Thanks to everyone that assisted me.
