Foldable light electric vehicles are the next phase of future sustainable transportation. Tricycles being one of the types for different age groups to ride, an electric tricycle is used as a design medium for including the foldability feature. The influence of foldability of bicycles and types of mechanisms of folding are studied and similar is applied at a different position than the common frame joints. Foldable position, space reducing characteristics and strength of the frame at the removable junction were measured. ANSYS software was used for the determining the stresses and deformation and analysed the extent of safe design. Hence, a satisfactory type of foldable tricycle was proposed for encouraging its benefits into future economic transportation.
