The purpose of this final project is to design a three-wheeled electric motorcycle with tadpole configuration which can tilt and is easily used by older and disabled people. The user does not have to put his feet down while in stationary condition because of the three wheels. <br /> <br /> Structural strength and performance of the three wheeled electric motorcycle is not analysed, for the design process is done to make sure the whole system works. The process starts with finding existing three-wheeled motorcycle which can be used as references to determine the dimensions and mechanism for the three wheeled electric motorcycle. <br /> <br /> The components of the three-wheeled electric vehicle to imitate the selected mechanism are designed with several criteria to fulfill. The required spring for the front part is analysed using Solidworks simulation, while the batteries and electric motor required are chosen by predicting the required energy and power to travel 40 km at an average velocity of 30 km/h. <br /> <br /> A 6 kW BLDC motor, 83.85 kg lithium polymer battery, and a couple of 31 N/mm springs are selected for the three-wheeled electric motorcycle.
