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!

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.

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.

I ordered 2 of these. The heel protection for the baby is nice except like others have said, the baby seat is mounted way too close to the bike seat. Also it’s weird it doesn’t mount to the mounting points on the bike frame. Instead it clamps around the frame and scratches it. Just seems to make it unnecessarily complicated and actually use more parts than if you could just mount it directly. Also the parts are cheap and 1 screw came defective, and they both ended up stripping so easily I had to get my own screws. Instructions are hard to follow. I ended up finding a you tube video for assembly.

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.

This was a terrible purchase. The plastic of the seat is so cheaply made, I would not feel safe leaving my child in it. It was flimsy, and felt like paper. Though I suppose that makes it light weight for riding ease, I was not comfortable with it. Needless to say, I still attempted and took it to a Bike Shop for installation. Even the bike mechanics thought this was a terrible product (and NO they did NOT try to sell me a different one - they just told me to get rid of this one altogether). Let me start by saying what the biggest problem is. The seat has no extending hardware, which means it only reaches as far as the small connector piece can reach. The picture sort of shows this, but not nearly to the extent it actually sits. This child seat was right up against the back of my seat. I ride a beach cruiser, and after lots of online research, found this to be a beach cruiser compatible child seat. WRONG! This chair was up against my chair, and the child handlebar was actually sitting ON my bike seat. If I tried to sit down, I sat on the child handlebar. That isn't even the worst of it. My child, who is 2 years old and 25 lbs, could not even comfortably get into the chair. We had to take some serious time to get him into it, because my bike seat was completely in his way. When he was finally sitting in it, his little legs were almost doing splits to fit around my adult seat. AND they did not even get around the seat entirely. So had I got on my bike, I would have been sitting on the handlebar AND my son's legs. And he is a little guy. I realize most of these chairs are close to the adult seat, but this was ridiculous. Also, many other chair types come with an extending piece of hardware that place the chair further back. Though I am not nearly the size of this woman in the photo, this is what I envisioned for my poor child if I actually used this product: [...] (see the link or google "fat lady child carrier"). And take a close look, that seat in the photo IS the Bell Classic Child Carrier. I wish I had seen this photo before I bought it. Then there is another safety issue. The wheel guard is terrible. It is a flimsy, cheap piece of plastic, which looks much like a piece of paper, and it basically attaches with twist ties over the tire. This is to keep the child's feet from getting stuck in the wheel, so it is very important to be safe and sturdy, which this IS NOT. I am so disappointed in this seat and have already issued a request to return it.

Did not have a hard time assembling it. It took me around 30 minutes by myself. I feel like there was a missing screw to it. But I had some extras at some and I ended up using it. Overall it's sturdy, my 7 month old baby fits in well. (Even though it's not advertised for under 1 year old)
