INTRODUCTION

This is a simple, small and light 4 wheel vehicle on pedals. Behind the seat there is enough space to move the seat back and fit the vehicle for an adult person. You can use it as a toy or to go to the nearest shop or bar (if the traffic situation in your neighbourhood allows it). It is a fun to drive it, but even a bigger fun to build it. And you suddenly become the biggest attraction in your neighbourhood!

I wanted my 9 years old son to learn basics of construction and working with metal and wood. He did almost all hand works by himself and he is very proud on it. It is a very good way to move your child from TV and computer games!

Construction of our do it yourself bike car is made of square Aluminium tubes, burden parts are made of steel. The whole construction is put together with screws, most of them M6.
