I will have a swat at what I think the question is.

Electric vehicles have a power to weight issue: Batteries weigh heavy, so to equalise things out the chassis and body should be light. Aluminium tubing - square section is easy to obtain (at a cost), you can join with pop rivets and some sheet aluminium corner fillets. 1.5 to 2mm thickness should be OK.

A chassis can be either a ladder or a space frame. In our racing car we built a space frame https://www.instructables.com/id/Building-an-electric-racing-car/

The body started out as plastic sheeting similar to that used for signs and then progressed to 1mm thick aluminium sheet.

For a motor Ebay will provide a number of 250 watt or larger 24 volt DC motors at a reasonable cost. With suitable gearing you should be able to get 50 miles at around 30 MPH out of a couple of car batteries. there are lots of other issues. you may find the information here useful as well.
