The powertrain of the vehicle alpha-prototype has been assembled and is ready for further validation analysis. All components were selected after a thorough evaluation process and with respect to the technologies functional requirements. The findings of this paper indicate that axial flux PM machines are the most suitable solution for vehicle tractive applications where low weight, compactness and high power is required. Using such a machine is however, not the most economically viable solution, due to the complex assembling method currently in use by manufacturer. The motor speed is controlled by a flux-vector, CAN protocol interface module. The CAN communication protocol interface allows redefinitions and modifications to all control parameters, which is a valuable tool in further development. Already existing technology is not considered able to meet all the specific requirements of the unique FEM. The system's battery module is equipped with relatively new battery cell technology that results in high energy density and high current output capability. However, the battery module is the heaviest component on the FEM. Reducing the module's size affects its output current capabilities, or output voltage level. This eventually results in a reduction of the vehicle's driving range, weight and power. The powertrain is a high power design, and capable of a long driving range. The weight must however be reduced to enable easier portability when folded. The vehicle's weight can be reduced by a lighter frame design which meets the vehicle requirements. The research indicates that the possibility of developing a powerful , light-weight, low cost and all-electric two-wheeler vehicle taking full advantage on today's city infrastructure is very prospective.
