All in all amazing thing to have for a child. The seat goes on both cruiser and mountain bike (at least that is what we used it on so far) and it only takes couple of minutes to install. Baby is in front of you facing forward and enjoys the view while i can keep an eye on my child. It takes a little time to adjust riding with the seat attached since you have to keep your legs more open than usual but even my 5 f 4 in wife has no issues and rides just fine. Seems secure but i would not take it on extreme routes sonce it is made of plastic. I give 4 stars only for a reason that the seat is so tight and not suitable for bigger kids. My child is only a year old and i don't think we will be able to use to for too long since he is already fitting pretty snug there.

This looks like a doll seat on the bike, but it was amazing. I put it on my beach cruiser and It took about an hour to get it on the bike because I am no good at putting things together. We took it camping and my littlest grand-kids loved, loved, loved it. It gave them plenty of support. It was easy to lift them into the carrier. I turned away to pick up my helmet and the bike fell over with the two year old strapped in. It scared him, but protected him with no injury.
I loved being able to see and talk to them while riding. I really hated having a kid on the back of my bike, as I was never sure how they were handling the ride. And it was fun for me to see how happy they were riding with me. I'm 62 and riding the bike with this carrier was much easier than the pull carrier I initially used. I'm healthy, but not athletic, and was riding on flat ground. I am 5'7' and didn't have any trouble with steering or pedaling my bike. My grand-kids are 5, 4, and 2. The 5 year old has a genetic issue and is tiny at about 34#. The 4 year old was the biggest at 38 pounds. And the 2 year old is a big health boy at about 26#. They all enjoyed riding. Especially the 2 year old, because he doesn't really like his push bike yet.

Easy to install and more importantly, very safe for young children. My son is a small 2 year, and it's a bit snug and he has to bend his knees a bit. Out of the box, it looked really small, but it actually ended up having enough space for the kid. This a good sized seat for even the smaller babies (1 year olds) The arm rest is perfect, and I didn't realize how useful enough until I saw it in action (it's comfy enough that my son holds on to it and doesn't even think about grabbing the handlebars - he probably can't see them).

I do have widen my knees while peddling, which is inconvenient, but I think the situation would be the same for any child bike seat I buy.

I want to start this off by saying I WANTED TO LOVE THIS PRODUCT. I really did.
PROS:
-Easy to install, tools included
-Great Price, quality materials
-minimal impact on center of gravity
-padded platform to rest weary heads/ hang on
-allows babies to see in front
CONS:
-doesn't fit all bikes
-knees knock into seat
-hunched over baby to reach handlebars.
I hastily popped the box open and got to work installing on my men's Trek 7.2fx. I don't recall the size at the moment (will edit once I look at the bike). The bike itself is a fitness hybrid, leaning more on the road style with thinner tires and a sportier ride.
My 1 year old LOVED the bike ride, she was able to see everything, wave her arms and wiggle her legs. She thoroughly enjoyed herself in the seat.
I however, struggled through the ride. I'm 5'7 woman with long-ish legs riding a men's bike- this child's seat did not fit for me. My knees knocked into the seat, so I had to pedal bowlegged, making my knees sore from the awkward angle and the hilly-ness of our neighborhood. The stability bar attached the seat to the bike (my handlebar is unthreaded), made it difficult to turn the handlebar in either direction. I leaned in the direction to steer us around for the most part, but making small adjustments while riding was challenging, like not having power steering in a car.
The other part was that I was leaning over my little passenger. She's 1, and In the 25th percentile for height, so she's on the small side height-wise. She couldn't properly sit back in the seat while I was pedaling. This is likely due to the style of my bike (hence why I included the background info), but it makes it uncomfortable for me and once she gets a tiny bit bigger, for her as well.
The last thing about the seat, is the straps. I couldn't get them small enough for her to stay secure. At one point she had both shoulder straps off and hanging onto the pad in front of her before we stopped and I adjusted her. The straps are very easy to adjust (huge plus), but this may tell you how small my girl is, the smallest setting wasn't small enough. I would suggest some type of padding or rubbery chest clip to keep the straps from slipping.
I give this 3 stars because I feel the center of gravity is great having the child in front. However, this is a challenging seat to fit on your bike. Likely a townie commuter (think Amsterdam bikes) or beach cruisers would fit this seat best. Longer handlebars and smaller pedal base(?) combined with more upright seating on the bike would do best with this seat. Rear seat for me it is.

I have had to modify the setup quit a bit to fit my Trek Stache 9 29+. My two year old son and I have used it to ride some serious trails in places like Moab and Fruita. We did the entire Switchgrass IMBA epic loop, no problems. We currently live in south central PA and frequently ride in places like Michaux. Once modified this setup is quite rugged and durable. I've cut off the front entirely so that the seat can be more forward, added a spacer for it to sit higher, added two bolts two hold the seat to the bar, added extra padding to the butt of the seat, etc. Moving the seat forward and up was essential for leg room while pedaling. I did have a scary moment with the foot buckets catching on the crown of my suspension forks, so these had to slightly modified with a heat gun and a higher stem added to make room for my toddler's legs. See the pics. The seat harness is great except for the shoulders straps do not stay in place. I just use duct tape. The harness could probably be made simpler and easier to adjust with new webbing, but I just haven't taken the time yet. Where the bar connects to the stem was a problem because the metal collar was gouging out the dust cap to my stem bearings. I remedied this by adding metal washers as spacers so that the plastic bushing was all that is making contact. After more than 40 hours of riding time, the setup is holding together nicely. I'll likely keep the bar and affix a bicycle seat to it when he gets bigger.

If you are not comfortable with making a number of modifications, then you might not like the WeeRide. But, you won't find anything quite as good as this is for trail riding.
