JOYSTAR Replacement Balance Bike Wheel, 12 Inch EVA Polymer Foam Tire Air Free Tire, Fits for Kids Balance BikeSingle

I needed to make up a cart to help my 88 pound rottweiler who was having issues with his back legs to get around. I was able to drill holes in the 1/2 inch tubing that I slapped the thing together with, and adjusted the axle bolt over a bit so that it would work. The wheels come with acorn nuts on them as well, so I did not have to buy any extra hardware. They are a bit over 11 inches (not quite 12 inches) but are very light and work very well for the purpose. One funny thing is that these are filled with foam (no air) but have a faux "air stem" molded into the wheel. That just made me giggle. The dog is getting around quite well in his cart (it is temporary until his custom built one arrives in about 2 weeks).

Wheels are great. The bearings needed a little lube but these worked excellent for the dog Wheelchair I had built.

These are exactly as described. My granddaughter has had her balance bike for a year now and it isn't avail. on Amazon anymore. I wasn't sure if these would work, they said universal for different brands. They worked perfectly and very easy to put on.Very happy!!

I got these to build a doggie wheelchair for a small dog. The advantage is that they're really lightweight and the tires are foam, so there's no risk of getting a flat. However, there's not much traction from the foam tires, particularly on smooth surfaces. Additionally, the bearings used are unsealed (and in my case, unlubricated), sitting in a plastic bearing race. There's quite a bit more rolling resistance than I anticipated, but I suppose it doesn't matter much for the intended use of a kid's scooter. I ended up 3D printing some hub spacers and using some skate bearings on an 8mm axle - this works amazingly.

The quality of the tire is excellent. The issue is that it is not for a Strider bike, unfortunately. Other than that I was happy, but I had to return it.

Good price on the (2) wheels that I purchased. Look good and just a few minutes to install. Only (minor) concerns were that they were a little tight to roll and have a very slight wobble. Not a problem for my grandsons balance bike though. Satisfied!

This is a great replacement/backup wheel for a kids balance bike. I bought this for my strider 14x and its fits perfect on the front wheel but the "axle" is too short on the rear. I want to put the strider skis on a 14x instead of a strider 12 which is what they are made for. These wheels worked after I get a new axle for the back and they are worth the price so I am glad I bought them. In case you are looking at this wheel for the same reason, the size of threaded rear axle you need to fit on a Strider 14x is M10-1.0x150mm (this is approximately 1.5 inches longer than the stock axle)

This bike tire is larger but it still worked to replace the back tire on my child’s Super Flyer bike from Canadian Tire which has no replacement tire available.
