My wife and I took the kids out camping last weekend, and my 5yr old daughter wanted her training wheels off. So I pulled the wheels, and removed her pedals so she could push around for a while to get her balance. After a few hours, the pedals went back on, and away she went. Good day watching your kids figure that out. Now she goes out every day when I get home from work to "show me" how far she can go. Love it!
