This is the stroller I settled on when looking for a jogging stroller to accommodate my 2.5 year old and 4.5 year old for runs when I don't have childcare available. I looked at several models and narrowed it down to this stroller and the Bob FLEX Duallie. I'll admit to being a bit in favor of Baby Jogger products since we own and love our City Select, but I tried to be fair when making my choice. Positives: - the canopies are some of the best I've seen on any stroller, especially a jogger -- sturdy, pull very far forward, windows, smooth movement when opening/closing (in contrast to the Bob canopies, which feel cheap sadly) - center support bar between the seats -- this is something you may not notice at first but when you are dealing with a child on the upper end of the height/weight, the lack of center support in the Bob can cause the seats to sag toward each other. - one step fold -- similar to the City Select, it takes one step to fold. Boom. - fits in my trunk easily (Nissan Rogue) - handle bar is NOT FOAM -- gah, I hate foam handle bars on strollers. Especially for sweaty hands. It degrades and comes off over time, kids pick at it, just not my favorite. This is a nice rubbery material. - hand break -- Bob doesn't have one on the FLEX (it does come on the pro I think). We have lots of hills on the multi-use paths we use, so this was a big plus for me. - solid build -- it feels quality when you fold and unfold, push, lift, etc. - sizable storage basket -- typically I access it from the sides. I can fit my bag or backpack, two small cooler bags, two kids towels, and a few more odds and ends at the zoo. Plenty of room. - deeper seat -- this is not something most people notice or think of, but the seat is deeper than the Bob FLEX (from knees to bum) -- my older son found this far, far more comfortable than the Bob because in the Bob he was practically sliding out of the seat due to the depth being shorter. - can use a single stroller parent console instead of specialized double console -- I was able to use the single console from our City Select because of the center bar -- it doesn't need to reach all the way across the double width. - easy recline -- my kids are old enough that we don't use this feature much, but the recline is easy to use one handed and goes nearly flat. - front wheel swivels or locks straight -- you can even lock it straight while moving with the lever on the side, instead of stopping and going around to the wheel, but this does take some practice Negatives: - foot break -- works well, and I have no issue with it due to wearing running shoes when I use this stroller, but it isn't as smooth/easy as the Bob. I know it would be hard to take the break off in flip flops. - belly bar and snack trays -- we are likely choosing to forgo these because you have to remove the entire bar to get children in and out of the stroller, instead of moving it to the side like on the City Select. Plus, you have to buy the bar AND the trays separately, adding quite a bit to the cost. - canopy does not adjust upwards for taller children -- I was used to this feature on the City Select and a bit sad that it wasn't possible on this stroller. - air filled tires -- while its likely these are "better" for a jogging stroller, the foam filled tires that never need filling on my City Select spoiled me. I'll have to keep an eye on these tires to make sure they stay full. Other thoughts: - weight -- Its a double jogger. Its going to be heavy. Personally, I don't think its that heavy at all but I have a friend who thought it was. Its a bit more than the Bob FLEX Duallie, but in pushing both I didn't notice. - non-adjustable handle bar -- this doesn't affect me because I'm a pretty average height, but a consideration if you are shorter or taller - "taller" than the Bob FLEX Duallie -- I'm not sure how to explain this, but the stroller is a bit more upright, whereas the Bob sits lower. This is NOT a problem for me, but some seem to have issues with it tipping backwards. We have not experienced this even with both boys reclined, but something to note. I personally like the way it sits, but I thought I would mention it. The only issue we have with it being a bit taller is that it is hard for my 2.5 year old to get in and out of on his own, but he is short for his age. To Note: My 4.5 year old is 39 lbs and about 43" tall and fits with a bit of room -- aka, his head slight brushes the top of the canopy when closed when he is sitting perfectly upright, but since he usually slouches down, its not an issue. His head actually seemed a bit more squished in the Bob. My younger son is 2.5 years and 26 lbs, 35" tall. Obviously he fits with plenty of room. There have not been any footwell kicking incidents yet, fortunately :) Overall, after trying out both the Bob FLEX Duallie and the Baby Jogger 2016 Summit x3 Double, the Summit was a better fit for my needs.
