As a self-study project, to learn about electric transport, I decided to build a small 10-inch track racer. I thought it might be fun to share this with the community.
Specs:
Propulsion: Hub motor, 4kW, BLDC
Battery: Custom lithium-ion, 72v 1kWh, 18650 cells
Wheelbase: 1000mm
Seat height: 600mm
Wheels: 10 Inch
Suspension: None
Frame: Custom stainless steel laser cut tubes, hinged at the top to remove the battery pack in an ergonomic fashion.
Seat: Woven string ''hammock''
Designs:
All the designs were done in Solidworks, after 16 evolutions I ended with this final concept.
The load carriering frame can be opened to remove the battery pack from the top.
Seat test:
First I 3D printed a 1:3 model of the subframe to pratice weaving patterns.
The final pattern in the 1:1 model were the seat will be woven in between.
Assembly of the Frame:
The frame is made from laser cut stainless steel tubes and sheet. I don't have access to grinding or milling machines so I found a company which could cut the shapes from my 3D STEP files. I choose stainless steel to save the need for paint and because it's just so lovely to weld.
