GHYREX Adjustable Universal Bike Training Wheels for 12-20 Inch Bikes with Flash Light Wheel, 1 Pair

Very easy to put together, shipped quickly, very cool light up wheels. I like the wheel type-reminds me more of rollerblade wheels than the cheap plastic I think of with the older training wheels

Easy to assemble and easy to put on bike . He loved the light up tiresome them

Easy assembly and work great!

Fast shipping quality parts. Can't wait for my daughter to use when the weather gets nice!

I purchased these because it says they work on 20" bikes. , We bought our son a BMX bike but he wasn't quite there yet without training wheels, and I thought these would be a good bridge for him. The length of the bar on the training wheels is appropriate, but the HOLE sizes are to small for the bike's rear axle spindle. I had to use a metal file to enlarge the holes on both the training wheels and the locking nut in order to get them on. So Buyer Beware! At least for larger axle spindles (although a $3 round metal file from Harbor Freight and a little elbow grease solved the problem rather quickly)

Really good came in time even after my last order was canceled the day it was supposed to be delivered was sent a message saying they where out if stock! So had to reorder a different set

Be prepared to have to rebuy some of the parts. Poor quality. The bolts threads wouldn't keep the nut on. Bought the bolts at a hardware store to put it together.

These training wheels do not fit on my daughter's bike, before I made this purchased, I checked for compatibility and the website said it was compatible, I found out that was incorrect. Not pleased at all.

My son cried tremendously cuz they won't fit on his huffy 20” bike.

Does NOT fit 20" bike. difficulties in installation needs a EXTENSION to fit. Extension available on other models.
