Thanks again to being a Stroller Traffic Scout, our family has enjoyed the new Babyzen yoyo+ board. We have always enjoyed our Yoyo (see review here), but now this is our main stay! Retailing for $125, the buddy board carries up to 44lbs. Staying true to all their features - the buddy board is insanely easy to install. Its a one-handed pinch to clip it on or off of the stroller. The saddle is easily removable, allowing for your child to sit or stand. My bike obsessed toddler can't wait to jump on the board when I pull the stroller out of the car!
I recently joined a friend at the zoo who has a 5 month old & 3 year old. They had brought an infant car seat & stroller for the 5 month old and the yoyo for the 3 year old. Perfect scenario to adapt the buddy board: once their baby is old enough for the yoyo, they only have to attach the buddy board for their toddler. The best part for an environment like the zoo, is the ability for the toddler to jump on and off. We now use this stroller for trips to the beach (it's SO light!), to the park and on every excursion!
My only bit of feedback in the event that you are on the shorter end, is that the buddy board can make the stroller a bit trickier to steer. I am 5'6'' and found that steering one-handed, while walking to the side was easier & quite doable given how manoeverable the yoyo is.
For reference, my children are 1.5 & 3.5 in the photos below.
