iBertChild Bicycle Safe-T-Seat, Light Blue, One Size

My 17 month granddaughter fits perfect will room to grow. The bar in front is hard to open and the strap release button is also hard those are my only 2 negatives.

I have a completely average hybrid bike and am a completely average 5'5" female, but this chair was 2-3" off from being able to fit on my bike so we had to install it on her dad's; he's 6'2" (not average) and it fit just right. Great seat, just disappointed we can't ride together.

My 2 year old fits perfectly in this seat . it is somewhat wobbly when you aren’t moving but that hasn’t been a problem for me .If your child is taller/ has longer legs you might want a different option my 2 year old is at the longest setting already & he is on the shorter side

Works great

This thing is perfect! Our 2 year old loves it! It fits really well even on my track back with very little space above the headset. If you have a bike (like a track bike) with very few spacers above the headset and perfectly flat top tube, the d-ring on the locking pin will hang down and hit the top tube. I had to get a small M3 bolt and nyloc nut to replace the d-ring/snap pin. I used a small zip tie and just cut it off after each ride for a few days and that worked too. There isn't any load on that part, just keeps it from sliding front to back or coming off the mounting bar.The mount itself is really simple and sturdy. The tool stores under the lap bar/steering wheel in case you need it. I wouldn't worry at all about my son falling off or breaking the mount. The top review on here shows a broken mount with some porosity in the casting. I can't imagine they still have that problem after making so many of them for this long. I will update this review after I take the mount to the quality lab at work and check it out.The seat is great! It's padded in the center where the kid sits and on their back, but not the sides. This is a good thing because it allows the seat to be so narrow. I have very little clearance between the bars, the stem, the headset, and the top tube, but this thing fits PERFECTLY! There is plenty of clearance for his legs, it's really narrow and doesn't affect my riding position very much. It's wider than my knees are apart, but with a properly sized bike frame my knees are clear of the seat. It's really awesome to have such a low impact on the riding position while having a child on your bike with you! I have a new mountain bike coming this weekend that should fit this setup even better, I'll update this review.Riding with this seat and a 28lb child is absolutely fine. The weight being on and mostly centered over the headset is almost unnoticeable. You can turn almost 90° each way fully unobstructed. The kid can even pull, kick, and play with the handle bars and since they are mounted on the same post, it' doesn't even slightly affect the steering of the bike. You d notice the fact that you are carrying 28 extra pounds with you, but not in an inconvenient way. He can play with the built-in "steering wheel" and he has a blast. Bumps and cracks in the road do not bother my son when in the seat, even on my track bike with 100psi in the tires. The padding does a nice job while not taking up too much room.This thing is super cool, but you really have to be 100% confident on a bike if you want to carry a child on a seat like this. Washing out on gravel in a turn, falling over your bars, hitting a curb wrong and dumping your bike, or even just having to stop unexpectedly and dropping your bike could end very badly for the kid. Even a hard 90° whip of the wheel when hitting a curb wrong could hurt a kid sitting in a seat a foot away from the rotation with no neck support. So, don't buy this if you are even slightly worried you can't handle it.

I wanted so badly to love this seat. Unfortunately, I just couldn't get it to be secure on my bike. Two parallel mostly flat bars are supposed to tighten around a tube. I could get it so the mount didn't move up or down but it could not be secured in a way that my son wouldn't tilt from side to side about 15 degrees either way. There's no way that's safe. He only weighs about 25lbs, so it's not like he's too heavy for the thing. It's either a poor design or something was missing from the seat I received. Which is entirely possible because I received a crushed return that STILL HAD THE ADDRESS OF THE PREVIOUS PURCHASER on it!The space between the handlebars and the seat is too small for legs to go in and out. As I said, my son is about 25 pounds and he's no chunky monkey.It was easy for me to pedal and my darling boy loved it.This seat was easy to install, and fortunately also easy to remove. Because I simply can't keep it. I just can't take my precious cargo out in a seat that's tilting side to side like he's on a carnival ride.

Seat looks great but I can't install because it's missing the two nuts to attach to get stem as well as the wrench...
