Umbrella type strollers are great for traveling. They take up little space, and can quickly be setup and collapsed. The downside is that if you are of above average height, even just a little, they are a pain to use. Either you walk like a hunchback, or you constantly kick the wheels and activate the breaks.
After dealing with it long enough, I decided to see what I could come up with. I wanted something cheap, and easy to disassemble so it wouldn't affect the portability of the stroller. I came up with two different handle designs. It cost less than a dollar more to make both, so it's worthwhile to be able to test both and see which suits you more.
Step 1: Materials and Tools
These are the materials I used, however, different stroller models will likely have different needs. Use this list to get a general idea of what you will need. I used 3/4 PVC because that's what fit the handles of my stroller. I stuck with 3/4 throughout as I figured it'd make a stiffer handle. It is easy to switch from 3/4 to 1/2, or 1/2 to 3/4 if needed. The best way to determine what suits you best is to wheel your stroller into a hardware store and start testing different fittings.
