PRUNUS Bike Training Wheels for 12 14 16 18 20 Inch.Training Wheels for Kids Bike is Heavy Duty.Bicycle Training Wheels is Suitable Single Speed Bike

These training wheels came with great instructions, and even the needed tools!

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.

I am returning these immediately. I attached them per instructions to my son's Trek bike. They worked fine ****IF***** he did nothing but ride in a straight line, but as soon as he tried to turn (thus putting more weight / force on them), they folded back and the bike tipped. I tightened the bolt on the wheel axle as tight as possible, but it was no use. Sliding still happened. I went into my local bike shop to see if they had any insights -- the bike technician said that the design is poor. High quality training wheels have brace / stabilizer arms that rests against the bike frame itself to prevent the issue I described above. I purchased such a set and it works like a charm (see second pic). The plain steel design is less attractive --- but it WORKS. He can now turn a corner without the bike tipping over. My recommendation to other customers is not to buy the PRUNUS set. The set I ultimately purchased is made by Wald (in business since 1905 .... they know what they are doing!). My recommendation to the folks at PRUNUS is to modify this set to include brace / stabilizer arms!

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."
