OP - STOREBicycle Training Wheels for Kids Stronger Version Replacement Adjustable Bicycles Stabilizer for Children, Suitable for 12/14/ 16/18/ 20/ inch Children's Single Speed Bikes (Black)

Easy to install.I love how it works with multiple sizes.It needed slight adjustment on a 16in wheel setup. Originally, it was too low when centered and would cause rear wheelspin.I adjusted both training wheels a bit more to the rear, and now it has a bit more wobble (this will help the kids learn to balance more) and doesn't burn out!

We purchased the training wheels for our son who wants to ride a 20 inch bike but is not quite ready to balance on his own. These are perfect for him right now. The training wheels were easy to install and sturdy enough for him to learn that he shouldn't rely on them all the time and that he needs to learn to balance. Overall, a good purchase. It came quickly and well packaged!

Simple product with a good range of sizes to fit different bike frames. Wheels Are not as durable as expected, after a couple of months they are a little more scratched than the use they had. But work perfectly fine and it is only cosmetic:

For starters this wasn’t entirely easy to install but once we got it on we figured it was ok. We purchased a 20inch for my daughter who’s still not 100% comfortable riding without training wheels. Well, she took off with all of her confidence and ended up on the floor because the training wheels completely bent and fell apart (& yes they were tightened and secure, well as tight and secure as we could make it).This did not work for us at all.If you have a 20 inch bike and are thinking of purchasing this, I’d advice against it. Not secure for bigger bikes at all.Good luck.

These training wheels WILL NOT fit the 20" Cycles, despite what it says.
