If your kid is stroller aged (can't quite keep up with you on a ruck run) and isn't riding a bike yet, you need a BOB. My oldest can keep up on his bike; my youngest gets a first-class ride and an awesome view. If it's a truly gnarly adventure, we bring out the Double so they can both sit. The BOB keeps up on runs, weight-vest rucks, and an occasional hike. Beyond this, the BOB crushes it at the zoo, theme park, and farmer's market. We've owned BOBs since my five year old was an infant but just recently tried out the new Revolution Flex 3.0 Single.
I haven't found anything that compares when it comes to turning and general “pushability.” Pneumatic tires and smooth bearings make it super smooth and easy when pushing. This smoothness translates very well to the handlebar. Since the stroller doesn't require a death grip to maneuver, you can make nearly infinite adjustments on the fly by adjusting hand tension, placement, or the handlebar itself. The Flex 3.0 adjusts and locks into 9 different positions with intuitive thumb buttons on either side. The handle material is also very comfortable over distance—temperature stays consistent and it handles moisture without issue.
As smooth as it is on the asphalt, it's even more fun (in my opinion) off the roads. It cruises on hard pack, fire roads, and trails. The suspension system combined with pneumatic tires do their job well. I've never heard my kids complain about being uncomfortable in the BOB and we've been over some pretty gnarly terrain.
The Flex 3.0 has some cool upgrades compared to previous models. The “peak and chat” window as they call it now uses magnets instead of Velcro (much easier to handle on the fly) and has a ventilated section that seems to do a much better job of letting soundwaves through—you can actually hear your kiddo. This might not seem like a big deal, but constantly having to stop to hear what your kid needs can get pretty frustrating (not an issue when the sunshade is pulled back). The upgraded storage and cell phone pockets are nice, but I'd still recommend adding a handlebar console if only for the ability to have water bottle access without stopping or having to reach down. The reclining system is also very smooth and easy to operate. I'm not sure when this design first appeared, but it's a great system.
Like other BOBs, the 3.0 folds down to a pretty small package. I've stored it multiple ways in our overpacked garage: hung it on walls, stuffed it in corners, and packed it onto the shelves. I'm always impressed at how much room it doesn't take up. The fold down process is very smooth and quick. The rear wheels are also extremely easy to take on and off—great design that wasn't on some of the earlier BOB models we tried. For the front wheel, they've upgraded to a thru-axle system instead of the previous quick-release style. I questioned this at first, but concur that this is an upgrade. The axle is super solid and you can't really mess it up—it's on right or not at all. It also requires much less maintenance compared to the original quick-release. Definitely think the 3.0 is an improvement on a stroller that I was already a fan of. [This review was collected as part of a promotion.]
