Car seat attachment is not a Flex strength

Our Verdict
The BOB Revolution Flex 3.0 is an impressive jogging stroller that can be combined with various infant car seats with the purchase of an adapter. The adapters require assembly and screw onto the frame, and car seats require two steps for attachment, including straps, which we worry parents will skip. While we love this BOB, and many things about it, it isn't the best for combining with a car seat as a result of the two-step design. The Flex is a great jogger, versatile enough for to use as your primary stroller, and easy to push, but there are better options (even joggers) if a travel system is what you want to create.

Our Analysis and Test Results

Ease of Attaching Car Seat
The Flex 3.0 can be combined with a variety of infant car seat brands with the purchase of an adapter.

The adapters are largely frames you need to assemble using a screwdriver before connecting to the stroller frame. Once connected to the stroller, the carrier clicks onto the adapter and requires a second step of strap connection to finish the combination.
The second strap step of the Flex 3.0 adapters hurt its overall performance results in the combo review as we worry parents might skip the step, leaving little ones open to potential injuries. Credit: Abriah Wofford

It is this second step that hurt the Flex's 3.0 performance in this metric. We worry parents will intentionally skip the second step or forget making the combination potentially dangerous for little ones. That being said, if a jogging stroller is what you want and you don't want to invest in a different stroller for the first 9 months of your baby's life, then the adapters work well, but please follow directions.
NO Running Before 8 Months
Experts agree you should not take an infant running until they have full head and neck control and can sit up unassisted, which typically occurs around 8 months. We suggest you consult your child's pediatrician before taking your little one over bumpy terrain or jogging.

Weight and Folded Size
The Flex 3.0 is a behemoth among car seat stroller combinations. While about average for a jogging stroller at 28.1 lbs with the car seat adapter attached, this could be prohibitively large for a new mother to lift. Folded, it measures 14,748 cubic inches, which isn't small and could be problematic.

Maneuverability
The Flex 3.0 is a breeze to push and turn with large rubber tires and a lockable swivel front wheel that makes tight turns with ease and can traverse almost any surface smoothly.

The 3.0 has adjustable suspension and handlebar making it somewhat customizable for pusher and passenger which can affect how challenging it is to move in small spaces or over bumps in the road.

Ease of Use
The 3.0 received top marks for ease of use in this review with no other being easier to use.

Folding the Flex 3.0 requires a quick pull on the handle under the seat; this is the second step after unlocking the dual locking mechanism on the frame. Credit: Abriah Wofford
Fold and Unfold
The BOB fold has more steps than some of the competition but it is isn't hard to accomplish. It has 3 steps and includes frame release levers, a pull handle, and manual lock. The stroller does not self-stand or have a carry strap.
The brake pedal on the Revolution 3.0 is large and easy to press. With a rocker style design, it can be engaged and released without hurting your shoes or feet. Credit: Abriah Wofford
Brakes
The Flex 3.0 has single action brakes with a center brake pedal on the back above the rear axle. The pedal is an easy to use rocker-style pedal that is friendly on feet. In our testing, we had difficulties with the brakes on our 3.0 that they didn't want to completely engage with the teeth on the brakes not fully engaging with the slots on the wheel. We had to jiggle the stroller a little to get the brakes to properly engage. We haven't experienced this with BOB brakes in the past.
The new 3.0 has more storage pockets than previous iterations and now includes 2 zippered pockets in addition to a large mesh pocket on the back of the canopy and seatback. Credit: Abriah Wofford

Storage
The 3.0 has an under-seat basket that holds up to 10 lbs, and fit our large diaper bag inside with access from the back and sides. It also has inside passenger pockets, back seat pockets, and pockets on the back of the canopy including a zippered pocket for phones or keys.
The canopy on the Revolution 3.0 has a smaller peek-a-boo window than previous models but the new ventilation is see-through and has the added perk of increased airflow. The cover is now silent magnet closures instead of the louder Velcro. Credit: Abriah Wofford
Sunshade
The new 3.0 canopy is still large like a traditional BOB sunshade but it has a smaller peek-a-boo window to make room for mesh ventilation. It also has upgrade closures with silent magnets instead of Velcro. The window is still large and easy to see through.

Ease of Setup
Set up for the 3.0 is simple with very little to add or do. It took about 4:30 minutes to assemble and the tools you need come in the box.

Quality
The Flex 3.0 is a high-quality option that looks and feels sturdy with attention to detail and an impressive overall fit and finish. We like the materials BOB uses and the frame is stable with few rattles or flexing.
