Simple and Secure!
Love, love, love this bike carrier seat. It's simple to install, doesn't weigh down when I'm riding, and they feel secure in it! I like the lap guard and how it cradles them in. I got this for my daughter when she was one, and she still fits comfortably in it two years later. I am about to buy a second one for my son so my husband can take him on rides with us too.

Good for little kids
This has been a great addition to our biking family. It has been very sturdy and comfortable for the back of our bike. The installation took a little longer than expected and wasn’t super clear. So, just make sure to take your time installing it. We use it on an old trek mountain bike which could be the problem. But once on it’s great!

Great, sturdy seat; a pain to install
I purchased the cocoon seat for my bike a couple of years ago and my son and I love it. He was just under one when I started using it and now he’s two and a half. I’m sad that he’ll soon be growing past the 40 lb weight limit because he loves riding with me and has even fallen asleep in the seat during rides. I feel the cocoon is a sturdy addition to my bike and have never felt unsure about my child’s safety. Conversely, this thing was a pain to install. Now, I’m not that mechanically adept, though I feel confident to put things together myself in general. It would have been easier if I installed this with someone else, but it took me some time to do it solo. I have a men’s mountain bike with brake cords and it was a little bit of a challenge to fit this seat without crimping those cords, but I managed to get it done. I give this four stars for its security and ease of use with my child, but deducted a star for ease of installation.

Great seat, very pleased!!
This seat is everything I expected. We had no problem attaching it to 2 different bikes (a Huffy and some other speed bike) when we went on vacation, and all you need is a wrench! I think anyone with a normal, standard bike and basic understanding of how to screw together bolts and nuts will have no problem putting together this seat (and the manual is very clear and self-explanatory.) You do need an anchor point near the bike seat to attach the main bracket. (That socket where you have the quick release to make the seat higher or lower.) While looking online, I noticed some new mountain bikes have it too low, and also the bars of the rear-wheel-fork were to thick. Consider these 2 things before buying this seat if you have a mountain bike. Otherwise, my daughter (14 mos) LOVED the seat. She sat in it very comfortably for 4.5 hours straight without even the slightest complaint. Before we left the bike tipped over and crashed to the ground, but nothing happened to her (aside for a little fright.) Her head, shoulders, and the rest of her body were completely protected by the side panel of the seat. The straps are fully-adjustable and kept her snug and tight in the seat. I absolutely recommend this seat to anyone looking for a child carrier, especially since it's so economical and practical, it makes a great first choice.

Read this before you buy.
The chair is nice and sturdy, the bracket mount It’s very manageable and you can Install in most cruiser bikes. It might fit on the hard tail mountain bike, but I’d say it will be very comfortable to pedal Most likely you’re gonna have to install some high bars like Bmx style handlebars to have a comfortable riding Position. If not, then you’re gonna have to be leaning over your child. one of the downsides of this chair is that the foot pegs or foot rest for the kids are very flimsy and plastic. But overall worth the money for a two years you can probably use this on your toddler. Recommendations: Only install on a cruise bike or hybrid with high handlebars. Like a city bike Installation is 6/10 easy.

Fun Way for small kids to Biking Adventure
I recently started using the Bell COCOON 300 Child Bicycle Carrier, and it has quickly become a favorite in our family, especially during the fall season. First off, the sturdiness of this carrier is impressive. It feels incredibly well-built, providing peace of mind knowing that my child is secure while we ride. The installation was straightforward, and it fits seamlessly on my bike. The adjustable straps and harness ensure a snug and safe fit for my little one, which is always a top priority. What really stands out is how much my kids love it! They enjoy the view and the feeling of being part of the adventure as we cruise through the colorful fall foliage. The padded seat adds extra comfort for longer rides, and the added safety features make every outing enjoyable for both of us. Overall, it’s a sturdy, reliable, and fun way to include my child in our biking adventure, and I highly recommend this carrier for any family looking to enjoy the outdoors together.

We tried a few different models before and nothing would work! This one is strong, comfortable, well fixed on the bike, my baby feel really safe in it! Best option in the market for sure!

Algo importante a comentar es que no es para todas las bicicletas, checar bien la descripción de la rodada de la llanta. No queda para las bicis que tienen los tubos curvos. Es seguro y fácil de instalar.

The blue key holder at the bottom slipped out and I need a replacement but there’s no product support!

Depending on the model of your bike, this might be one of the few baby chairs that fit. That's my case. I was so happy when I finally found this chair! My one-year-old is very comfortable in it. The straps can be regulated.

Muy buen producto, muy facil de instalar siguiendo las instrucciones al pie de la letra, un poco justo al asiento, sin embargo mi bicicleta es de 29” pero muy recomendable
