Little World Bicycle Training Wheels, Variable Speed Bike Training Wheels Bicycle Stabilizers Mounted Kit for Kids Variable Bike of 18 20 22 Inch, 1 Pair (Sliver)

These are extremely sturdy compared to most (not a flimsy metal) they worked for my application with a bit of modification (had to bend the cross brace a bit on the non gear side due to a kickstand that I had to remove) the up and down adjustment was spot on the wheels are basic cheapos but there training wheels and could probably be swapped out with a pair of the flashy ones that you probably already purchased that didn’t fit originally 😉

I mounted these on my grand daughters 20" Schwinn. They come with extender nuts to fit on the end of the axle. The brackets only fit when the extenders are installed. The thread pitch on the extenders is 10mm x 1.0. The threads on the axle are 3/8"-24 fine thread. The extenders will not fit the bikes axle! I believe most kids bikes are the 3/8" thread. I am a mechanic, so I already have a 3/8"- 24 tap. I tapped the threads on the extender to fit the bikes axle. I did have to go to the hardware store to buy (2) 10mm x 1.0 nuts. I also had to trim a bit off the left hand bracket to clear the mounting tab for the coaster brake. If you are considering this set, it might be worth it to pick up a 10mm x 1.0 nut to try on your bike axle first. If it fits, you're good to go. If not, you will also need to buy a 3/8" -24 tap to use these. All this being said, they seem like a pretty sturdy set of training wheels.

Great bike! It is very well made and was easy to assemble. It did not take a long time for it to be delivered from the time I ordered it. My granddaughter was so excited and loves it! I would buy from this seller again.

Right side won't fit to frame. Left side the whole won't line-up with the screw on the frame. Because it's an irregular part. I tried hammering, still won't work. I ended up just used the tire/wheel and put on the old training wheels arm/support. Don't make the same mistake like I did and just return the item and don't wasted your time trying to make it fit. I'm a mechanic and a auto body guy,btw.

Have an old 20" Schwinn Stingray bike that I wanted to add training wheels on. Had bought a set from Bell but even though these say they are for 20" wheels they were too short. Ordered these. When they arrived promptly I saw they were considerable heavier duty than the Bell ones. The issue was the right one was bent slightly such that I couldn't fasten to the spindle and the fram. The left mounted grest but not the right. It took several whacks with a rubber mallet and some bending in a machine vise to get it back in line. The problem with the left one was that it could not accomodate the coaster brake. I had to grind off part of the braket to get it to fit. The positive note is that there was plenty of hole options for both the outriggers and the wheel positions so that once I got them mounted to the bike I was able to adjust very precisely. Overall I'm happy with the purchase it just took longer and required more effort than it should have.

Works as it should. Easy install.

My wife bought a (barely) used bike from a friend. I didn't know until after she got it home, that it has gears so the training wheels that I had bought in advance won't work.So I bought these. They're perfect! They are sturdy, made of good materials (best that I can tell) and the minor adjustments that I can make for the "height" of the training wheel - allowing me to make the training wheels closer to the ground or a bit higher to help allow my daughter to work on her balance - is great. Right now, I have the wheels all the way to the ground so she can gain confidence. The previous bike she had with traditional training wheels, she was afraid of because it was a little unstable when she turned sharply. It felt like it was going to flip over. The most I could get her to stay on that bike was less than five minutes.I put these training wheels on her 20" bike and I had to beg for her to take a break to eat lunch. She stayed on it for about 45 minutes and didn't want to come off. Never saw her smile so much.So would I recommend these? Yes, absolutely!

Very flimsy. They bent after a couple of tines riding and were no longer touching the ground. Also it feels like they were made fir smaller bikes and not adult size ones. I bought this for my daughter to learn riding an adult size bike. She’s talk enough for it. She tried it once and it was a fail. She ended up learning without them. I sent it back. The return process was very easy and no problems.
