These training wheels fit most childrens’ bikes with 16″ or 20″ wheels. The brace arms are designed to fit rear frame tubes up to 3/4″ inches in diameter. The maximum rider weight for these training wheels is 100 pounds. These wheels may not be compatible with a bike with a rear derailleur. Instead, see Sunlite Adjustable Bike Training Wheels. If you haven’t yet bought a bike for your child, consider a Strider Child Balance Bike and leapfrog over the training wheel phase.
