Abstract/Artist Statement

The purpose of this project is to design and fabricate a hybrid tricycle that is powered by both an electric motor and a gas engine for maximum fuel economy. The focus of this design is based on the need for a relatively inexpensive and efficient type of transportation that can also be used for recreational purposes. The vehicle has a user-friendly control system that is safe to operate and requires low maintenance. The vehicle achieves a top speed of 20 mph with a minimum range of 40 miles. In order to accommodate both power sources, a Schwinn 26-inch Adult Tricycle was selected as the vehicle chassis. The electric motor power source is a 800W 36V hubcentric motor that is fitted to a 26-inch wheel with a thumb control throttle. The gas engine power source is a 2-stroke 80cc engine. The tricycle’s main drive shaft is modified to fit the chain-driven system of the 80cc engine. Finally, the vehicle is modified and tested to optimize ride-comfort and full functionality of the control systems while production costs were below $1,000.
