Review on Upgraded Heavy Duty Rear Bicycle Stabilizers Kit with Stronger Version Training Wheels for Boys and Girls - Fits 12, 14, 16, 18, and 20 Inch Bikes by Donnie King

I can't even assemble it! Wrong size parts! The bolts they sent were too long so the tires can't even stay straight because they are too loose. I looked for our own 16" training wheels and tried to use their bolts, but the axles on the Revain tires are thicker so the regular bolts wouldn't fit either. I ended up using old tires and their bolts with new support rods. I was able to mount the training wheels, but the silver piece of metal between the bike and the support bar didn't fit properly. You have to sand the piece like other reviews say. I don't know what to do now because I don't have a metal grinding tool and I don't want to breathe it. A complete waste of time. Can you send me the correct details!?
