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

The PRUNUS Flash BIKE training wheels are fantastic! They fit perfectly on my child’s 12–20 inch bike and provide excellent stability, making learning to ride much safer and more confidence-boosting. Installation was quick and straightforward—the instructions were clear, and the hardware felt durable and secure. The wheels are strong enough to handle active use without wobbling or coming loose. A reliable, high-quality set of training wheels that really helps kids gain balance and confidence while riding. Highly recommend for parents teaching their little ones to ride! ⭐⭐⭐⭐⭐

Got them in an hour and saved the day!! They work as should and lights are bright!! Easy as 1-2-3 to install. Good materiel and quality made... definitely recommend

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!

"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."

Good and durable. Had to return though as they didn’t fit the 20in bike I needed them for.

**EDITED TO ADD: the seller reached out to remedy the situation. When I let them know the bike and training wheels had unfortunately been run over by a truck and destroyed, they sent a full refund! It shows such compassion. We were able to make the wheels work by simply filing the tab part that fits into the fork by the wheels fyi.** The product itself is nice, sturdy, and great wheels....BUT beware that the supplied mounting may need to be modified or will not fit! The 2 little metal tab pieces that fit in between the wheel mount and the bike to keep the training wheel from rotating did not fit our bike.

having trouble to assemble

These light-up training wheels are a total hit with my kid! Installation was super easy — took about 15 minutes with basic tools. The wheels feel sturdy and safe, and the lights are so cool! They light up as the bike moves, which not only looks amazing but also helps with visibility when it starts getting dark. My 5-year-old is obsessed and actually wants to go out riding more often now. It’s a great way to add a bit of fun and safety to the learning-to-ride process. Definitely recommend for any little cyclist!
