A lot of strollers say one hand fold but the real test is where the release sits and how heavy the frame feels in motion. When you grip the handle does your thumb land on a single control you can operate without shifting your hand. Set the brake so it does not creep forward and then try a smooth pull and see if it starts collapsing under its own weight instead of needing a second hand to shove things into place so yeah if it clicks shut and stays compact while you pick it up by the same hand and that is the good kind. If you have to hunt for a latch each time, it gets old fast.
On broken sidewalks I keep the front end light by slightly lifting as I roll over cracks and raised seams. For longer rough stretches I lock the swivels so it tracks straight, then unlock when I need to turn. Keep the wheels clean and free of hair, add a touch of dry silicone if the hinges feel sticky, and put heavier items low in the basket to keep the center of gravity down. Shorter steps smooth things out. Works great.
