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.

Finally I can mountain bike again and now with the kid. Works great. It does make it hard to pedal standing making ascending harder but that is unavoidable with a 30lb child riding in front of you and behind the handbars.

The strap problem (which did continuously slide down) was easily fixed with velco wire organization wraps as shown. Now the straps stay on great and hold her comfortably enough to fall asleep in the woods bouncing around.

This deserves a 4.5 star in my book. This is really fun for the kid. Mine is generally excited and jumpy, but he stays real still and curious about all the scenery we pass by. It's definitely better than the back seating kind because they can see everything. You also have more control to save them if you or they fall.

The only cons I see is that the straps constantly fall off. I think the belt could also be separated in half for easier placement. As a workaround at least for the straps, I hook up a small bungee cord from the dollar store that works just fine.

I would recommend this, but would love to see the above improvements.

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.
