The Push-ped
A bike/scooter hybrid,a great project for begginer hobbiyists like me (please go easy on the coments cuz this is my first project and im only 13)
The How To
its basically just a regular Razor scooter with a metal bar welded on to it with added suports and a bike seat, The pics should give you an Idea (tip you should remove the wheels before welding to avoid melting)
