Riding a bike is a great exercise and also, a lot of fun. A tricycle is great for your toddler’s coordination and muscle strength. Learning to ride a pedal bike without the learning wheel is also an important milestone for your kids. You can usually teach your kids to ride the pedal bikes at around 3 to 8 years old, with an average of just over age 5. However, it also depends upon the pace with which your child is developing. Some kids are comfortable with bikes at an age of 3 while others learn late.
