DDJKCZ Training Wheels Flash Mute Wheel Bicycle Compatible for Bikes of 12 14 16 18 20 Inch

These training wheels fit my grandson’s bike perfectly.

These are nice and sturdy. They don't consistent light up. But that was not or primary reason for purchase so we still gave it five stars.

Worked well, as expected

Does not work on mongoose bikes. The support brackets just very barely touched the opening they are supposed to sit in to keep the wheels in place. I managed to tighten them down to at least give them a try but i was already worried they wouldn't hold up as maybe just 1/4 millimeter of it was barely holding it in place.The other big issue which prevented us from using it is that the wheels were far off from the ground providing no support. If we went up a slot then it was way too long and the bike wheel didn't touch the ground.Not sure if it's even returnable at this point as when you tighten the nut it scrapes off the paint.

My son was 8 years old and he learned how to ride a bike with this wheels. Then i throwed away because its not that strong. Easily bend after couple of hard move. Thak god my son learned in couple of days and we didnt need it much.
