Paxterra's Photon Base Frame is infinitely extensible with simple modifications that have little or no impact on other models due to our steel tubing frame structure. Modular construction with common materials makes this kind of vehicle doable anywhere. This sketch implies a lift mechanism. Some drivers could also negotiate a ramp.
Our next phase of development is to comprehensively test the Base Frame element to validate the Chassis Engineering Design. After this extensive battery of tests the Base Frame Element will be released with full documentation as a public domain electric vehicle. Until then we hope people will continue to follow and support us in this effort to bring safe, simple, affordable transportation to all the people of the World.
