I installed this awesome training wheels on my son 20-in bike. They fit very good , and So far they've been doing great, and the battery last long time.

Fit well sturdy construction easy to install

"I bought these for my child’s 18 inch bike because the original wheels were worn out.The Good: These are definitely heavy-duty. The brackets are thicker than the ones that came with the bike, and I don't worry about them snapping or warping. Installation was surprisingly easy—it took me about 10 minutes with the included tools, and the instructions were clear enough to follow without a headache.The Bad: My only real disappointment is the 'Flash' feature. My kid was excited for bright, glowing wheels, but they’re actually pretty dim. You have to be moving at a decent speed to get them to light up, and even then, the colors aren't very vibrant. They look more like a faint glow than a light show.Verdict: Great if you want a stable, safe set of training wheels that won't break. Just don't buy them solely for the light-up effect."

My complaint would be they were hard to put on the bike, more because the nuts on the bike were too wide and the bolt too short. Solved this by getting thinner bolts from the hardware store. Cheap fix. One of the wheels came off while he was riding it. Put back on and seems to be ok now. The lights are great. The family likes walking the dog at night and the kids ride their bikes. The lights help the bike be seen.
