12 Inch Children's Bikes

In the mini size 12 inches, there are two completely different favorite toys. On the one hand, you can buy running wheels here, i.e. vehicles that don't need much technology and are pushed forward with the feet. But there are also already real small bikes that have a drive around a pedal crank. These children's bikes often come with training wheels, so that young bikers can safely make their first attempts at riding. But how do you find the right bike for a child?
