Review on 🚲 BicyKids BNKIHDD Training Wheels: Superior Quality Replacement Stabilizers for 12-20 Inch Single Speed Bikes by Adam Bates

First you need tools to do this. They sent a wrench which was essentially useless (didn't match the screw they "put in"). Second, they're very long, which is both a good thing and a bad thing. In my case that was bad as for a bike for my 3 year old (which is smaller than the bike) they stuck out about four or five inches. I ended up cutting them to size. It also means I have to buy a new set when he outgrows his bike. Again, they're not bad, but not great.
