Children grow quickly, and parents are constantly replacing clothes, shoes, and toys to accommodate the size changes. To limit the need to replace toy vehicles, the goal of this project is to design and build a children’s toy pedal car that extends with them as they grow between the ages of 5 and 7. This growing pedal car is the only toy automobile on the market in which the whole car extends for the selected age range, making the car useful for several years and comfortable for the growing child. The final design uses a telescoping frame to extend the distance from the seat to the pedals and an adjustable steering wheel to create a 10-inch extension to accommodate the growth of children in this age range. The vehicle is recommended for a child up to 70 lbs.
