There are so many wonderful lightweight baby strollers on the market that narrowing it down to just one is quite difficult. My absolute favorite that I have in the back of my car and was just using earlier today is the Baby Jogger City Mini. It is a very lightweight stroller, SUPER easy to fold, turns on a dime, awesome sun canopy, decent storage basket and storage pocket, and infinite seat recline. At only 16 pounds I can hold my daughter in one arm, and use my free hand to pull the strap in the seat of the stroller, folding it and lifting it into the back of my car ONE HANDED and in one quick easy motion. It’s not just a one hand fold, but a one handed lift as well! Since the Baby Jogger City Mini isn’t an umbrella stroller it also doesn’t tip when you hang the diaper bag on it (which you’re not *supposed* to do), yet it still has a small and compact fold. The wheels are easy enough to remove that my 4 year old can take them off too, but I’m not sure why you’d need it that small.
Another wonderful stroller is the Baby Jogger City Elite. This is a fancier version with more seat padding, included parent console and adjustable handlebar and larger air filled tires. It’s not nearly as lightweight, but for a high end stroller that you can go jogging with or push over heavier terrain, it’s really not that heavy. It sort of crosses between classes in my opinion. The larger wheels make it slightly larger, but they are removable. The bigger wheels and additional seat padding make it weigh in at about 25 pounds. Assuming you’re able to lift your little one into their car seat, you’ll be able to lift this into your trunk without any trouble.
There are so many lightweight baby stroller options to choose from that this barely scratches the surface, but Baby Jogger is my current favorite. As far as weight goes, the Baby Jogger City Mini (BJCM) is my #1 pick! Baby Jogger makes both of these strollers in a double version that I love as well.
