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

Look's nice and well built. I wish it worked on my granddaughter's "HUFFY" bike. Chain guard prevented installation.

the picture attached to this review is from the first time ordering. ( I didn't add a 2nd because I put them on the bike as soon as the package arrived and forgot!) The problems I had with the first order seemed to be more a delivery issue than a product/ seller issue. I received a replacement for this order and they work perfectly. The replacement took a few days to get to me in NC, so I assume it came directly from the seller, which wasn't a problem at all.The seller contacted me because of the issue I was having and offered to make it right. I didn't respond to them at first because I'd ordered a replacement and because of the condition of the first order, I was pretty confident it wasn't a seller issue. After receiving the replacement I contacted them to make them aware all was well! I was able to install in about 20 minutes and the blue matches my daughters bike perfectly. She hasn't taken it out yet due to the weather. But the install was quick and directions were clear.If it means anything, I'm a woman with longer nails. And I had no problem installing. It probably took me a few extra minutes because of my nails and trying to attached the bolts to the wheel.

The wheels look good and lights up as advertised. I haven’t had them that long and somehow I already had to tighten them up. My son tends to ride his bike around the house. We never took it outside and the wheels already loosened, fell off and had to be reinstalled. This is the reason I didn’t give it 5 stars.

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!

Very sturdy easy to assemble

Didn't fit the bike, had to purchase longer screws!

Assembly instructions were very clear. Quality appears to be very good as well. Looking forward to my grandson using these on his bike.

Training wheels were a good fit for my daughter's bike. It was a 18inch bicycle. They light up when in motion. Nice product.
