The Skinny

The BOB Revolution Flex Duallie has almost every feature you might need, without nods to superfluous accessories. The Flex is easy to maneuver, uses quality materials, is easy to use, with ample storage, and impressive performance in most areas. This stroller will win your heart, mind, feet, hands, and just about every other part of you, which is why we gave it Top Pick for All-Terrain strolling. We think parents will enjoy the versatility of moving off-road and jogging with ease. This stroller provides families with more opportunities for adventure, something we think is good for everyone. We would recommend it to friends.

Our Analysis and Test Results

The Beast of Burden Company (aka.BOB), was started in 1994 by Roger Malinowski and Philip Novotny. Located in San Luis Obispo, California, the company built Yak bike trailers. The partners, a bicycle professional and airline mechanic, discovered a need for rugged jogging stroller after having babies of their own. The two advance the stroller's design over time, and are the first to include a locking swivel wheel in 2005. This alteration created a user-friendly, versatile stroller for jogging and other activities. Britax acquired BOB in 2011.

The BOB Revolution Flex Duallie is a great all-terrain stroller with adjustable suspension and rubber pneumatic tires that accepts one infant car seat. These models are 7 1/2 months old and a 5 yr old that is 40 lbs and 44 in.

Performance Comparison


This comparison chart shows the overall scores for all the strollers tested in this review with the BOB Revolution Duallie Flex (in blue).


The information provided below includes details on how the BOB performed during testing for each metric.

Ease of Use


The BOB earned a 7 of 10 for ease of use tying with the similar Thule Urban Glide 2 Double.


This score is second place for the group.

The folding pull handle on the BOB is easy to find and use.
The BOB folds in part by squeezing levers on the sides of the frame simultaneously.

Fold and Unfold


The BOB is a two hand fold with a manual lock that does not self-stand and has no carry handle or strap. It folds in 4-6 steps that are easy to manage. The most difficult part of the fold comes after the fold when you have to lift it to move it. The thick fold means it is harder to wiggle into tight spaces, and it might prohibit it from public transport. The unfolding is just as easy as the folding, it can be performed in 2-3 steps, and isn't a strain. You can do it with 1 or 2 hands depending on your skills.

The brakes on the BOB are single action and easy to use.

Brakes


The brakes are single action with a long bar that goes across the back. The pedal is plastic, large, with easy access, and is sandal foot-friendly, and easy to set. Releasing the brakes is easier, and there is no chance of thinking the brakes are engaged if they are not.

The BOB storage bin is easy to access from behind  but it is fairly far under the handlebar.
The storage bin on the 2016 BOB is a good sized bin  but could hold larger bags if it didn't have the center strap blocking the opening.

Storage


The storage is a large under seat bin that is easy to access from the back and sides. It fits our large diaper bag with supplies for two, but it is a little hard to get it in given the back strap. There is room to spare for other items, and the bin can still be accessed with the seats fully reclined.

The BOB also has large stow pockets on the backs of the seats. These pockets are good for items like phones and wallets, but they can be hard to reach with the seats reclined. The BOB offers two mesh stow pockets for each passenger. The pockets are large enough to hold a sippy cup or favorite toy and can be reached with the passenger buckled in and reclined.

The peek-a-boo windows on the BOB allow parents to keep an eye on little ones without opening the canopy.

Sunshade


The dual canopies are very large and move independently for individual passenger comfort. They are the same canvas material as the rest of the stroller and are water resistant. Each has a large vinyl peek-a-boo window with hook and loop closures. The window cover rolls up and can be secured to keep constant visual contact. The canopy extends past the knees of most passengers offering superior sun protection.

The BOB has a very utilitarian feel to its design and structure.
The BOB Revolution Flex Duallie seats do not recline as far as some of the competition  but it is far enough for comfortable napping for most children.
The photos above show the BOB with the seat backs upright and canopies closed and the seat backs fully reclined with the canopies fully extended.

The plastic red loops on the BOB Revolution Flex Duallie's harness make adjustment very easy with a simple pull to tighten. The shoulder straps could be a little difficult to adjust due to the padding on the straps.

Harness


The BOB has a 5-point harness for each seat that has an adjustable crotch strap and five shoulder height adjustment. The harness is easy to adjust at all points, easy to put on, and easy to take off. The buckle can be released using just one hand. The adjustment points and buckles are clear of fabrics and are easy to access. The harness has padded shoulder straps for additional comfort.

Seat


There is no adjustable leg rest, but it offers a padded leg rest with ample legroom for both passengers and a relatively large footrest. There is a strap on the transition point from seat bottom to leg rest that is rough and could potentially rub on sensitive skin. Each seat back can recline independently allowing for personal comfort. The recline works with a strap on the back of the seat that isn't super easy, but with two hands it can happen fairly quickly.

The car seat attachment for the BOB uses an adapter (sold separately) that is both a snap on and strap in type of attachment making it more difficult than much of the competition.

Car Seat Compatibility


The BOB can accept one infant car seat. The adapter is a frame style, does not need assembly, and the canopy can stay. It is compatible with BOB and Britax seats, and some Graco, Chicco and Peg Perego options. We tested the Revolution with the Britax B-Safe 35, Chicco Keyfit 30, Graco Click Connect, and the Peg Perego Primo Viaggio 4-35. All of the seats click onto the adapter and require the second step of attaching a strap. We fear some parents will forget or intentionally choose not to use the strap leaving baby open to potential injury. The Primo Viaggio did score slightly higher than the others.



Ease of Setup


The BOB is easy to set up and took us just over 6 minutes to assemble. The manual is clear with good pictures where relevant. There is only one language per manual, which is nice. The assembly is quick and requires no tools. We like the new quick release change to the rear wheels over the previous version's release.



It took us longer to get it out of the box and read the instructions than it did to assemble, and we caution that it is heavy and difficult to get out of the box with only one person.

The tires on the BOB Revolution Flex Duallie are air filled rubber and helped the stroller earn a high score in our tests for maneuverability. This stroller will easily roam over almost any terrain.

Maneuverability


Nothing maneuvers like a BOB, with a score of 9 of 10 it proves that even a double side-by-side stroller can be easy to move in tight spaces over various terrain.


The BOB tied with the Thule Urban Glide 2 Double and the Thule Chariot Cross 2.

The front swivel wheel on the BOB can be locked in place for increased control over uneven terrain.
The front swivel wheel on the BOB can be locked in place for increased control over uneven terrain.

Maneuvering on hard surfaces is a breeze with its three-wheel design and pneumatic tires, it can turn on a dime and take tight corners without preparation. While the side-by-side wider footprint can make navigation tricky, the one front wheel helps offset this by being easier to get into spaces without catching wheels on baseboards or chair legs. The width makes it trickier to get through the narrower doorways you might find in a public restroom, but it is still better than really long inline models.

FThe wheels on the BOB are larger than most, and its trike design and rubber tires give it an edge for all terrains. Going up curbs is also easier given the larger size of the back wheels and the placement of the brake bar.

The BOB is a large folded package  and it is awkward to pick up thanks to its shape.

Weight and Folded Size


The Revolution earned a 4 of 10 for weight and folded size thanks to a heavier than average weight and a large, cumbersome folded package. The BOB weighs just over 34 lbs, while the average is 32.2 lbs. The heaviest stroller is close to 40 lbs. The similar Thule Urban Glide 2 Double weighs 32.6 lbs and has a smaller fold.


The BOB's folded measurements come to 22,507 cubic inches. The BOB is not compact, but it is shorter than some, and you can remove the wheels to make it somewhat smaller. It may not fit in a standard trunk with wheels on, and you might have to secure the trunk lid closed if it sits strangely inside.

The BOB earned a high score for quality  despite our feelings of a decrease in attention to detail from previous incarnations of BOB strollers.

Quality


The BOB earned an 8 of 10 for quality. The top scoring products in this review are the Thule Urban Glide 2 Double and the Thule Chariot Cross 2 with 9s.


BOB uses Poly and Dobby weave fabrics that have a water-repellent coating and include open cell foam padding. The material appears durable, snag resistant, and sewn nicely to the frame. The seat padding is thermo-molded, and portions of the seat and canopy have reflective accents. The footrest seems thicker and tougher than the material on the rest of the product. The fabric is spill resistant and can be spot cleaned.

The new BOB has less fabric than previous BOBs covering the ventilation on the back of the reclined seat.
The under seat storage bin is large enough for everything you might need to bring on the road
The photos above show the current Revolution (left) and the previous Revolution (right).

The frame on the Revolution is powder coated chromoly and aluminum. It has tight connection joints, and there is no flex in the frame when pushing. The frame is relatively lightweight but manages to maintain a substantial feel.

The BOB has high-impact polymer composite wheels with pneumatic tires. The back wheels are 16 inches, and the front is 12 ½ inches. The tires have tubes that are pneumatic with Schrader valves, and easy to replace with quick release design.

The BOB has an adjustable handlebar that rotate on a pivot. This places taller pushers closer to the stroller which can lead ot kicking of the rear axle.

The BOB has a nice sized handlebar that is easy to grip. It offers firm, comfortable foam padding and the bar extends straight across the back of the frame; it might be better with a more ergonomic design. The handlebar is adjustable on a pivot point with one of the widest ranges. This product also comes with a safety strap to ensure the stroller never gets away from the pusher.

The Revolution has a nice fit and finish. Everything looks designed with performance and function in mind. There are no rough edges or poor stitching, and while it feels industrial, it gives the impression that it gets the job done and will for years to come.

The BOB seats and harness are nicely padded, and the suspension offers coil spring and elastomer core shock absorbers. The shock release knobs have two positions with a position for weight between 1-50 pounds and a second position for 50-100 pounds.

The BOB is really only good for older twins that can sit independently and support their own heads. It cannot be used with 2 infants  making it a poor choice for newborn twins.

Twins


The BOB is not the best stroller for twins. The BOB only accepts one infant car seat. More importantly, you can't use the regular seats until the baby is at least six months old or has adequate head control. Jogging is also ill-advised until your baby is at least 8-12 months according to the manufacturer's manual, and we suggest you speak with your baby's pediatrician before taking off. These issues make the BOB a better choice for families with children of different ages, or who are already old enough to sit upright without assistance.

Accessories


BOB offers lots of accessory options for the Duallie:
  • The BOB Child Accessory Tray gives little ones somewhere to keep snacks and cups. While some reviewers say it is too far away from passengers to use, we think it can still be useful with children in the upright position.
  • If you're serious about fitness or getting into shape, the BOB also has a BOB Duallie Fitness Kit for getting in a complete body workout while pushing your children. This accessory is a thoughtful gift for any active mom. This kit comes with the Strider version of the Duallie. If you purchase a different version and still want the fitness kit, it is nice to know you can get it as an accessory.

Other Versions


BOB offers three Duallie options; we only reviewed the Revolution Flex. The other options are the 2016 Revolution Pro Duallie, the and 2016 Stroller Strides Duallie. The Strides option comes with a fitness kit and parent console. In all other ways, it looks like it is the same as the Flex. The Pro model has a different colored frame and hand brake for the slowing on hills. In all other ways, it looks to be the same as the Flex. Depending on your goals and plans with the BOB one of these options might be a better fit for you.
