DOUBLE 2 CTraining Wheels, Heavy Duty Bicycle Training Wheels for Kids Bike Stabilizer Mounted Kit Compatible for 16 18 20 22 inch Bike (1 Pair)

Sturdy! My husband had to bend them with a hammer to fit just right but they are perfect now. We bought another pair that bent every time my son rode his bike. He is 70 plus pounds so we needed sturdy ones. Not that easy to put together if you are me(not handy at all), but my husband put them together pretty quickly. I’m pleased with how strong they are. No bending or breaking!

Left wheel bolt too short - wheel falls off. Right side will not fit single speed hub, had to cut off 90 degree support to fit. Had to buy 3/8 bolt, nuts, lock washer, and washers to use. Spacer adapter for right side threaded wrong and would not hold to wheel stud.Poor quality - dont purchase. I had to modify unit as my daughter wanted to ride right away.

Si quefo muy bien

Training Wheels were easy to install if you are even slightly mechanically inclined. However, it does not come with instructions.Wrenches/Sockets you will need:5/8 (SAE) - please note that if you are using the axle extension bolt, you will either want to use a wrench or a deep socket12mm13mmHex Driver/Bit / Allen Wrench5mmI removed one star from the overall ranking because the channels on the back of the telescopic rods were so narrow that I couldn't fit a socket over the nut, so I had to use a wrench.

I didn’t like not having any Instructions to assist with installation.

Let me stay off by saying that this is my experience and your mileage may vary.My daughter wanted to learn to ride and she needs a 20” bike due to her height. We bought a Huffy and these have short axles which have an odd thread. I tried three sets of training wheels and different axle extensions, none of which would fit.Out of frustration, I used a 2 lb hammer to bend the right side mount on these to fit the frame and successfully got them mounted. I can attest to the strength of the steel these are made from, as it took a great deal of effort to bend the mount only slightly!In hind sight, spend a bit extra on a bicycle which can better accommodate training wheels upfront. I’d say that the wheels will likely be the first failure point as they are plastic. The steel components are extremely sturdy. I’d really like to see better wheels included with these sets.

These training wheels are the best! My son is a little bit heavier and to boot didnt know how to ride his bike. The stock training wheels that came with his bike were too flimsy so i needed to find some durable and affordable ones. Other ones i found at local stores and online were not sturdy enough. These training wheels are the best! Installation was easy and they fit the bike's frame perfectly! They are even strong enough to hold him up even when he sometimes rides to the side. I wholeheartedly recommend these for anything with wheels that needs some sturdy assistance.

While the product technically works, it’s poorly designed. The lock nuts included are too large even for thin walled sockets to tighten effectively. This results in wheels that are looser than I’d like. Also, the nut and bolt combo that attaches the part of the of the kit from the bike the the wheel had to be installed backwards in order to properly tightened.Cannot recommend.
