Axle Extenders for Training Wheels - These Bike Axle Extension Bolts are Suitable for The Extension of The Rear Axle of Bicycly

I bought these for use with some 3D printed antenna components. They worked great for this application and were much less expensive than other 3/8-24 thread extensions being offered.

Makes training wheels a snap to put on

This set doesn’t come with an anti-rotation bar like the set I ordered for my daughter’s bike. So no matter how tight you get the bolt, the training wheels won’t stay in place, and they quickly slip forward or backward while riding, causing a fall, which is what I wanted to prevent by getting training wheels. Spend the extra $3 and make sure you get the ones that come with the bolts and the anti-rotation bars like the picture on the right. I wouldn’t have ordered them if I had know how useless they are.

Bought these as we were late to the game when it came to bikes for our kids. They are past the height and age where bikes bought at Walmart already have training wheels installed, and the ones we did buy didn't have rear bolts long enough to house training wheels.These extenders were a life saver or we thought they were. Traditional training wheels or the ones you see everywhere on Amazon won't work. The training wheels we bought come with a standard bracket that slips over the bolt and sits in the open spot of the frame and keeps the training wheel from pushing backwards when weight is applied to it. with the extenders you can't hook that anti twist on there. You have to buy training wheels that have a longer anti twist that attaches to the actual frame of the bike. Was annoying and greatly delayed us getting the kids up and running.

Fit well on the Huffy Rock It! 20” bike my mother bought for my 8 yr old for Christmas. My kiddo was what you’d a “scaredy cat” up until about last year when he finally began taking more chances. He’s finally ready to learn to ride a bike but it’s hard to find a 20” bike with training wheels and apparently it’s even harder to find training wheels for a 20” Huffy. After finally finding compatible training wheels, found out I also needed to get extenders. Huffy specified his bike model needed 3/8" x 24tpi axle extenders which I purchased, despite the seller indicating they may not be compatible. I’m assuming a good majority of Huffy bikes use 26tpi and seller was bombarded with returns/complaints so I suggest you confirm with the bike manufacturer on which size you need before purchasing.

I bought these extenders and after they came I realized that I also needed stabilizers and had to order those with another set of extenders. This was my fault. Make sure you read the description carefully if you need stabilizers for your kids bike. I kept them for spares.

I had a hard time finding extenders that are really the right size for g-daughters 20" bike that needs training wheels. The axles on her bike are 3/8" × 24TPI, not metric. I ordered training wheels w extenders and stabilizers which were metric. this seller has both options for the extenders. all this trouble because the 20" bikes don't come with long enough axels in the first place!

I got them very quickly and were perfect for my granddaughters bike.

A beautiful detail on my car

Couldn't find any in store so I figured I would give this a try. It worked great to extend one of the rear bolts on my sons bike out so we could put a regular training wheel over the gears. Fit a bit tight, but for a new thread I kind of expected that. Glad I got it! Thanks!

I installed them on a bike to add training wheels and the training wheels slid all over the place the momentweight was applied. They just don’t screen and lock against a smooth surface.Danger hazard if you child want to ride without you present
