Adjusting stem/handle bars

Hi i have a small bike that i cant find online as its old . The stem and handle bars are welded together. Just how its made. I can adjust the height of the stem and there is a groove so you cant wiggle it really from left to right. My question is can i take it out?The stem folds near the base of it but the handle bars are just a bit too long. I know i could probably have them trimmed but no this is a very small 14" wheeled bike. Not really what i want. I tried to get the handle bars out but just cant seem to. There is a quick release that is used to adjust the height but there something stopping it coming out. I just cant figure out what. Is this normal. This is a very simple bike that was originally a ebike and i took the ebike stuff off. Just wanna make it as light and foldable to travel with when that starts to be a thing again. In one way i want to put another kit on there to electrify it again but 14" kits seems to not be a thing. Anyway thats for another part of the forum

I think you need pictures if you want good help. On some of my Dahons for example there is no adjustment. Roger

You lower/raise the stem on the top quick release as you indicated. Not knowing your bike the maker made have made it so you can't pull it out by mistake and crash. I would call them and ask if it is supposed to come out. Roger

there are clamp on pieces to add another handlebar and have it adjustable,,

in the case of Brompton & Dahons the bar is clamped in the bar mast It's 1" @ that center point
these 2 pieces clamp on a 1" stub where the bar was, and a 2nd set of clamps in these 2 pieces grab a new bar

You will find a couple designs here: Handlebars, Extenders and Bar Ends

Might take some sawing and reinforcing the remaining T part , if its a suitable diameter..

do you own a proper caliper to measure things?

ok ok maybe. Was hoping not to buy anything and just work with what i have.
oh not sure what you mean about what the Brompton and Dahons have or do.
oh as i reply i am not linked to anything ....so um not sure. clicking on the blue writing does nothing.
I dont think i have calipers but not really into replacing anything if i can. I have very little money

On older folding bikes the stem assembly usually is held in with an expanding wedge like most older bikes were. You may have to take it out and do some disassembly to get it out. If you only want to trim the handlebar, why not do it in place.

Oh dont know what that is. ok will have to have a closer look and see if i can figure out more. The weather has been so awful that spending time on the porch doing anything is hard. This is where the bike is stored. I dont want to trim the handbars
