Roll Over Image to Zoom in Bicycle Training Wheels Fits 16 18 20 22 24 inch Kids Variable Bike

Brilliant product

The negative reviews on here are largely down to user error, but hardly their fault because there are no instructions. If you are looking at these, it is probably because it is for a bigger kids bike that might have gears. That is why one of the arms is a different shape, because you off-set it with the spacer bolts so it is away from the gears and mechanism. The spacer bolts are M10 with a 1.0mm pitch, which is standard for most bicycles. The spacer bolts are poorly made by someone who needs a new tap and die set. I found that threading them into each other with a bit of force and grease/WD40 sorts them out and then become much easier to work with. IF YOUR BIKE HAS A QUICK RELEASE WHEEL you will need an M10 to M5 fine thread adaptor. PATIKIL sell brass ones on Amazon in packs of 5. I have not fitted them yet because I am waiting for the thread adaptors, but they seem fine and sturdy. I would recommend using some insulation tape or something on the frame of your bike where the support arm makes contact. I have gone early with this review to hopefully help someone who is struggling. Update: I damaged the quick release. It isn’t strong enough for this. If you have a quick release you will need to replace it with a solid core rear axle, probably 180mm one, not expensive, just time consuming.

You need a threaded axle for this setup i leanred the expensive way guys but the setup is great easy to use and dont look too bad either

Item doesn't fit to a 24" bike as stated in the description. I purchased these to fit a bike for my young daughter so she has confidence to ride a bike she had for Christmas. Doesn't fit a 24" bike, so be mindful when ordering. Other than this, fitting to a bike it looks sturdy and the wheels feel solid, so it may be fine to fit a smaller wheel frame bike other than the inch wheel as stated.

This wheels are for 20' frame max. I tried to fit them to my son's 24' bike and just broke thread in axle. Couldn't test it but seems taught and sturdy but completely not suitable for bigger bikes.

Great for balance issues, easy to fit too

Very good and strong, but there were no instructions in the box, had to rely on pictures on Amazon

These are ok, and quite sturdy. They don't quite fit my daughters bike properly, and they come loose really easily. They have scratched the frame on her bike by coming loose. I have had to wrap the frame with some old car coolant hose to bridge the gap between the frame and the bits that are meant to locate onto it. Even after all that, I took her out on her bike yesterday, and again, one of them has come loose. It almost needs some kind of adapter plate to be able to fix it on with 2 bolts. It'll do the job, but don't risk your life on these things... one hit against a dropped curb and they come loose. I wouldn't buy them again to be honest.

Se ajustan perfectamente

Aslında güzel ürün ama yanlış bilgi veriyorlar. 16-24 inç janntlar için uygun yazılmış. Ama çocuğun bisikleti 16 inç en düşük seviyede ayarlamama rağmen bisiklet tekerleği havada kalıyor. Ayrıda tekerleği bisiklete tutturmam için gerekli somunlar içinden çıkmadı. Kendim başka yerden ayarladım. Ama şimdi hiç bir işimize yaramıyor. 20 jant in uygun en düşük.

Ottimo prodotto, regolabile e facile da montare

Para la bicicleta que tengo lo he probado, y no me sirve, no se puede ajustar, lo siento, por eso he pedido ,otros más simples que llegarán hoy y espero que me valgan.

Fits perfectly kids 20inch Fluid bicycle. If your kids bike has got gears, this is the item to buy as you will need the spacer for the right wheel. Very easy to install
