PRUNUS Flash Bike Training Wheels for 12 14 16 18 20 In Single-Speed Bikes

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

Likes, love the way the wheels light up, they have roller bearings, and the bracket seemed to be strong steel. Roll very tightly andquietly, And they fit right. Dislikes, the only thing that came in the box was the brackets and the wheels. But it only cost me four bucks to go down to the hardware store to get the bolts nuts and washers to bolt those wheels onto the brackets. And I had the extra nuts already to bolt the brackets on the bike… at first, I was going to send it back but the email to contact the company for support didn’t go thru. So I just decided to go spend the four bucks for the bolts. And kind of glad I did……… Edited to add that the company saw my review and is reimbursing me for the hardware, I am very happy now… and they work great.

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."

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.

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.

Easy installation and adjustment
