Bicycle 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

Bueno y resistente

My little dude was happy and couldn't wait 'til I was done installing these. We used these for good couple of months and then slowly got him to a balance bike for few weeks when we noticed the training wheels were barely touching the ground sometimes. Now he's good riding without, just need to work on our confidence part. These are sturdy and functional with a bonus bell.

Pros: -Easy to install Cons: -No instructions in the box, had to refer to the images here on Amazon -Only had enough washers for 1 wheel in the box -you get 2 flimsy metal wrenches to try to assemble the wheels, you need some proper tools to assemble this effectively Overall: It does the job. It fits properly on the kiddie bike I attached them to. However, I was missing some washers when I received this (there are supposed to be 2 washers for each wheel, I only received enough washers for 1 wheel so I had to improvise).

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.

Installed these on my son's new 20" bike. These are similar to Rollerblade wheels and, I have to say, I like these a lot better than the standard plastic wheels. They are quiet and roll smoothly. I'm not as big a fan of the mounting hardware that attaches to the rear of the bike. However, it does seem to do the job and holds the wheels in place once installed. Overall, I have to say I'm pleased with the wheels. UPDATE: Tonight while we were riding, my son mentioned his bike was getting hard to pedal. We noticed his right wheel was starting to wobble a little and was showing excessive wear. We stopped so i could check the wheel, the nut holding the wheel on seemed tight. By this time we were almost home so we thought we'd continue on for the next block and take a closer look at home. Right after we got going again, the wheel suddenly came off and my son son ended up crashing his bike. Fortunately he wasn't hurt. It looks like the wheel bearing just came apart, the nut is still tight and secure. While I still like this style of wheel, I now question the quality of the bearings. If we decide to try this style of wheel again, I'd probably consider placing a large flat washer on the outside of the wheel to help keep it on should the bearing fall apart again. UPDATE #2: I attempted to contact the seller to inquire about any warranty the wheels might have. They promptly replied and kindly offered to send a new set.

Easily attached to bike!

Works as should but be sure to use these with toddlers and not bigger/heavier kids

They do not fit on a 20” bike at the max adjustment hole, they bike is unstable and wobbles should be longer or shouldn’t say they will work on a 20” bike
