Just what I needed. It took about 2 minutes to install and feels very sturdy. This fit perfect on my panama jack beach cruiser bike.

BEST PURCHASE! I read through many different seats to purchase because I have a 5 yr old son who would rather ride with me than ride his bike. I was hesitant looking at other items until I came to this specific seat. What a time and life saver! The seat is extremely light yet VERY sturdy. I have a huffy beach cruiser that came with the attached rack on back. This seat was soooooooooooooo easy to attach I had it on and secured in less than 30 seconds after getting it out of the box. It was in one piece so absolutely no assembly required other than to slide on rack and tighten the clamps. Voila! Best of all, he fits perfectly in itand adds no bulky unsteady weight. My bike is a beast as is lol. His body is not cramped and I'm free of his appendages unless he reaches out to tap me on the back. The foot rests are adjustable as his legs grow. This will fit any rack right off the bat whether your bike came with one or you have to buy. This is a hassle free seat to attach and reattach. I didnt need the owners manual. Once its out of the box, one look at it and its obvious what 2 simple steps you have to take. Even the harnesses are alreay set and ready to go. The harness and clamps are very secure. My 5 yr old has attmpted to unfasten them when we stop but he is unable. It does take a bit of effort which is great because I dont fear him coming loose. Also you have to make sure you push down til you hear it snap in place between the legs. If it doesnt, its not secured. Additional perk for me, I got it the very next day FedEx! Want a seat you can use for a while and seiously get your moneys worth from? Look no further. This is it!

I have a 26" Northrock XC-6 mountain bike (from Costco). 50% of the time, I use the bike for actual mountain biking at various parks, etc and the other 50% of the time, i'm on leisurely bike rides with my kids.

Once the seat-post latch is installed (maybe 45-60 minutes if you take your time), it takes less than 5 seconds to remove or attach the seat and be ready for whatever the occasion calls for.

When attached, the seat is sturdy and safe for my 18 month old. I feel like he could definitely use this seat up until he was 3 or 4 years old (my 5 year old actually fits). I saw some complaints about the harnesses 'ease-of-use' and to be honest, it's not that hard people! The only way it can be difficult is if you try to put the harness on WHILE your child's helmet is on. So... don't. Put you child in the seat, buckle him in, put his helmet on - voila. To unbuckle, remove your child's helmet first.

When removed, all that's left on my bike is the seat-post latch. It's so small and barely noticeable. My legs don't scrape the latch while riding and it's not in the way of any of my brake cables or tools. Also, i'm still able to keep my water bottle and tire pump mounted on the bike!
When the seat is removed, it stays together in one piece so I can quickly remove it and set it aside without worrying about loose or fragile parts.

The only modification that I needed to make was to the seat's spoke guards which do a great job of protecting tiny legs from the rear wheel and road debris. The lowest corner of the guards barely touched my rear tire and would make a little noise while riding. It wouldn't have caused any damage to my bike and the plastic guard would have eventually worn away but I went ahead, with a standard utility knife, trimmed about 1/4" off - perfection was achieved!

Bare in mind, all bikes are slightly different.
I can guarantee that your Northrock or standard 26" Giant brand mountain bike will accept this baby carrier.
I'm confident that, with minor modifications, this seat would work on most any 26" cruiser, road, or mountain bike without rear-suspension.

A good solution for mounting without needing a rear rack on the bike. The seat is a bit upright and with a helmet on your child can't really lean their head back (especially if they fall asleep). Just wish it had a recline option! As the child gets bigger/heavier I assume it will sag a bit more and recline a bit. Also, the straps don't go tight enough for really small children. My son is 20 lbs and the straps are a bit loose if not wearing a jacket. Also note that the helmet will have to be put on after strapped in. Overall a good option compared to some of the more expensive bike seats.

Child can unhook harness by leaning on it. I am trying to contact the seller because my seat is either defective or this is a serious safety hazard. The clasp comes unhooked by applying barely any pressure to it. I had my friend's two year old in the seat and it came unhooked 5 times!! This is extremely dangerous!!
