One of the biggest temptations is buying a child's first bike that they will grow into. However, this will likely have the opposite effect and put your child off bikes and cycling altogether! Another common mistake is to buy a cheap children's bike, but these models are often as heavy as a child, which can lead to frustration because they cannot ride. That's why Frog bikes are lightweight and specifically designed for children's anatomy.
