FORTOP Bicycle Training Wheels Heavy Duty Rear with Stabilizers Mounted Kit for Kids Boy Girls Bikes of 12 14 16 18 20 Inch

While I was generally pleased with the looks and improvement over the cheap wheels that typically come with a Box store bike…. I had to modify both the wheel bracket and the retention bracket in order to get the nut back on the wheel stud. As seen in the photo I had to hammer them both flat

The metal on top is too thick to fit between the frame and the nut, I had to slide them inside on the tire side and the frame to make them fit on my kids bike. Don’t order these unless you’re mechanically inclined and can rig them on.

Laterals are too thin. My 5 year old folds them every time he uses his bike.

This didn't fit my child's bike. Apparently, the Huffy bike we have uses an EZ connect feature for training wheels. Because of this, I was unable to connect these. Even when I tried to modify it to fit, it was blocked by the chain guard. Worth thinking about how it will fit before buying.

Pros: sturdy brackets, good wheels for this purpose.Cons: the instructions are unclear, unnecessarily long, and say nothing about how to attach the wheels to your bike. The provided wrench is barely adequate - one size too large, and awkward to use at the angle needed. Even if you use it, you will need another (small crescent/socket/locking pliers) wrench of your own to hold the other end of the bolt.My advice: Believe you can figure it out and just do it. Attach the provided circular washer and training wheel to the single hole in the bracket. Tighten with a wrench on each end of the bolt. Take the nuts off the rear axle if your bike, slip on the rectangular washer-like piece with the small tab in the fork, then the bracket hole of your choice, and put the original bike nut back on.My beef: One bearing spins nicely, the other has a little friction. Works well enough, though.

Pros:* fairly quiet wheels (much quieter than the training wheels that were packaged with a Schwinn). That's why I bought them, so they met my major expectation.Cons:* instructions were absolute garbage. The only way I knew where the washer was supposed to go was by reading the very tiny print in the picture with the instructions, which was not an assembly illustration. Fortunately, it does not take a genius to figure out how to install training wheels. But these were shamefully bad instructions.* the claimed 16" measurement is no accurate short. There is no configuration on my kid's 16" Schwinn that allows all four wheels to be on the ground. That's OK after a kid gets used to it, but it should be an option. I used longer (and sturdier) brackets from other wheels to get an extra ½ inch.* the lights only work when going at high speed and even then only intermittently. Given that only one wheel will touch the ground at a time (see above), it's hard to get sustained lights.

Only dislike is only one wheel lights up. Other never did light up or work.

My son is a big 4 year old and got his new 20" bike for his birthday. The bike shop only had flimsy training wheels, so I ordered these because of the overwhelmingly positive reviews. The support arms seemed vastly better than anything else I had come across, and the wheels have little embedded LEDs that light up when spun quickly. They seemed great.Then when I mounted the support arms to the rear fork of the bike, the little clips that keep the training wheel arms in place weren't long enough, so they badly scratched the paint on fork of the (new) bicycle. I worked around that limitation and managed to effectively mount the training wheels, and my son was off to the races. He loved them for a total of about 3 hours, until he wiped out due to the wheel coming apart and falling off! Make no mistake, I followed the directions when assembling these things. The entire kit came with one of each, for each side: a nut, bolt, washer, and wheel. There was only one washer (which I thought was odd.) And the instructions said to put that one washer behind the arm, under the lock-nut, and not on the outside of the wheel hub under the bolt. After the wheel completely fell apart, I thought about putting it back together and putting a few additional washers on the outside of the wheel hub to keep it all in place, but the bearing cases were bent, everything inside was a hot mess. I had to hammer the bolt out of the wheel hub. And the other side was in bad enough shape that it too would be falling apart soon.I'm really sorry, but this is a classic example of a great design with superior mounting arms, and one component (the wheel hub) was so cheaply made that it makes the product worthless beyond a few uses. Honestly, it probably shouldn't be sold. I would absolutely not recommend this product. Returned to Amazon, and requested a refund, not a replacement.

I wanted to replace noisy training wheels that came with bike. This one doesn't make noise, support is strong, but the bearings are cheap and wheels don't rotate freely. One of the wheel also don't light up.l after a few use.
