It i called a detent lever, part # 2030052. Usually a repair shop can order this for you. Or you might try bissell.com and see if you buy it online from them.

the handle bars run thru your neck in the center, you should find a hex head bolt inthe center of the neck, loosen it then pull the handle bars up, be careful not to unscrew the entire bolt in the neck

Most likely you have a threaded headset on your wifes bikes. Many times you will have to replace some of the cables and housing because they will be too short once the handlesbars are raised.

If you have a treadless headset than raising your handlebars is very simple. First check to see what type of headset you have. A threadless system with have a allen head on the very top of the stem and one or two more allen head bolts on the side of the stem. The threaded system will usually have only one bolt on the very top of the stem. It is sometimes covered by some type of cap. Also on threaded headsets, there will be a large nut under the stem, which is what most people mistakenly loosen to adjust the stem. Do not touch this nut, it will adjust the headset. Same goes for the allen head on the treadless headset, it will also adjust the headset so don't touch it.
So if you have a threaded stem, simply loosen the allen head or nut on the top of the stem and raise the stem up. Make sure you do not go above the max line and that you are still able to turn the handlebars freely.

Hope this helps!
