Design Analysis of Portable Electric Two-Wheeler with Enhanced Safety Features

Abstract

Metropolitan cities today face twin crisis of mobility pollution and high-priced fossil fuels. Another issue that these places face is limited space of vehicle movement and upkeep in residences. The present work addresses these issues with a designed portable electric two-wheeler that can be carried as luggage trolley and can be kept in room. The designed two-wheeler is having a total weight of 28 kg with folded and unfolded horizontal length of 70cm& 140cm while height and width equals to 85 and 53 cm respectively. The vehicle is equipped with 3 phase, 48 volt, 250 W BLDC motor, 48 V controller and with two wheels of 32 cm diameter each. The system is powered with 4 batteries of 12 volt each to power the wheels. The designed electric two-wheeler is made foldable with help of scissor mechanism fitted at the centre of the system. The system is fitted with foldable mirrors and rear-view display for enhanced safety in its class. The system is tested on different gradients and variable loading for design test for enhanced market acceptability. Results indicate that the design is suited for individual travel with no noise / air pollution in congested city travelling.
