YL Trd Adjustable Bike Training Wheels Bicycle Stabilizers Mounted Kit for 18-20 inch Multi-Geared Bike

Bought for my 7yr old grandson's "big bike". Easy to install, sturdy, and good enough. Probably won't use them long enough to evaluate how well they hold up. However, for now, they serve their purpose well.

stronger brackets, but had to modify to get it to fit. Not sure there is a ONE SIZE FITS all,but I chose these for the look of the strength of the bracket. I ended up using to Hose Clamps to attach the supports to the frame.

These worked great for my daughter's Trek MT 220 with 16" wheels. They are adjustable and can probably fit a 20" wheel bike - not sure if they would be able to fit anything larger. My daughter had no interest in learning to ride a bike until she had outgrown traditional, smaller bikes. With theses, she was riding her bike without training wheels after just a couple days. Well worth the purchase.

Training wheels were easy to put onto bike. Fit perfect. Works great.

Obviously my mistake for not checking it during the return window, but this kit came with the wrong Hardware. If you use the bolts that it says to use, the ones provided, none of the washers or screws fit. They are all too small, not even close. Unfortunately a waste of money.

Good stuff.

Served their purpose

One side fits, but not the other one. But it'll work I guess.
