(I know the front tire is on wrong, I fixed it)
I'm not a bike pro by any means, but I got this bike and the handlebars were low and flat. I didn't like it. So I took to amazon and found these for $13. It took a little tweaking with the cables, I had to borrow some cable housing from another bike to get the brakes to reach.
I don't know if this is what you're looking for or not, but has worked well for me.
