SPORUS Training Wheels, Thicken Bike Training Wheels for Kids Under 70lb with Heavy Duty Magnesium Alloy for 18 Inch Black [Including Mounted Kit]

No hardware was in the box (looks like it may have been a return) ; I had to purchase some at the hardware store. I also had to cut out part of the plastic chain cover so these would mount correctly. Lights do not look as pictured, there is only one small line of lights in the middle of the wheel that light up when the wheel turns. It is so important to mount the wheel properly, one side of the center hole sticks out farther than the other side and this must be on the outside or the wheel won't turn. I got these to work and they are super sturdy. I wouldn't buy these again or recommend them. Installation for most people will be difficult.

So sad that I missed the return window on these. We kept trying to give them another chance, but every time my daughter tried to ride with these, they kicked out and made her unstable. We would tighten them again as much as possible. This last time she tried them, and it almost flipped her completely over. 😕

Not the size indicated and wouldn't fit on the toddler size 10" bike. Returned and did not find another option. Ended up buying another bike with training wheels :(

So hard to put on. Even with the diagram emailed to me the training wheels look backwards and I could not screw them on properly. My husband and my son tried as well. So I had to return them

I bought 2 pairs one 16in and one 18in. Within 2weeks each bike had broke just below the bolt. They are horrible training wheels!!!!6

I was looking for rainbow wheels like product description. These were plain black.

Good product!
