Adjust the seat on the Red Bullet Balance Bike so your child can start, coast, and stop by pushing her feet on the ground. She'll learn how to keep it upright, no training wheels required. 3 years+, $50; chiccoshop.com
Depending on how fast they grow, big kids can ride a 24-inch bike through their teens. Diamondback's Della Cruz has coaster brakes (she just pedals backward to stop) and a steel frame. 8 years+, $220; amazon.com
