Reddit mentions of Delta Cycle Bike Bicycle Stem Raiser Extender Head Up Handlebar Raiser

Unfortunately you can't easily make the handlebar higher easily You could use something like this

As for the fork the adjustment just locks out the suspension is all.

Still it's a great find for $60.

Something like this might bring it up a little further. It's a 90mm long 45 degree angle stem.

Combine it with something like this and it would get even higher.

Another issue you're going to run into is cable length. The cable on your left hand brake looks like it's just long enough to fit the current height. If you push it up with new bars you're going to need a new cable. With a 5" rise I'd be willing to bet you're going to need all new cables. Unless you can do it yourself you may want to sell your bike and buy a Roll like your friends. That's going to get expensive if a shop is doing it.

Edit: https://www.amazon.com/Delta-Cycle-Alloy-Bicycle-Raiser/dp/B000FGYKWS/ A stem riser might help get your existing bars up higher.

That one does not ship to where I am. These three do, which one would you recommend:

Yes, you can use either one of these, but it looks like you'll also need to lengthen the brake cable. If you get the adjustable one I'm posting, it'll pull the bars back to the rider, giving the same effect, and you might not have to lengthen the cable. all these types of products come in different lengths too. Make sure to measure the stem width, usually 1 1/8th across.

That said, this is the least graceful way to solve your problem

you've got the wrong fork extender

I've extended steerer tubes on several bikes. The I've owned this bike for many years (it has an old style headset).

The parts are readily avalable at Amazon or eBay...

The above comes in a short or long version. I've had these on my bikes for quite some time, and no problems.
