Okay guys. You can't beat the value for money (compared to what you find in hardware stores). However, watch out for the smell when you open the box. I didn't believe the other reviews that insisted these wheels stink, but unfortunately it is true. I had to take the whole box outside and let it air out for a few days before bringing them inside. I also rubbed each of the wheels twice with white vinegar, hoping to get the smell off the rubber wheels quickly. Once you get past that stage, everything about these bikes will be great. Excellent price. Pretty good quality. I used #8 screws. I found them so useful that I bought another set of 24. This time I open the box from the outside and prepare my white vinegar!
