Design of an Energy Efficient Bicycle

Project Overview

In this project a design and installation of a new gear mechanism attached to a motor on a bicycle that contributes in decreasing the required torque efforts from the rider on inclined surfaces to accelerate a bicycle. This project mechanism will be applied in two main scenarios while going up on a hill and by going down. When going uphill, the driver of the bicycle will have to increase the effort, with that more pedaling will be required to overcome all forces acting against the bicycle.
The first part of the project is by utilizing a motor that will be connected to the rear gear hub by a chain initiated by a switch fixed right next to the rider’s left hand. This switch will start/stop the motor to contribute in reducing the pedaling force.
The second part of the project is by a generator connected to clutch to be engaged in the hub to charge the battery and decelerate the bicycle at the same time. Mainly it is a mechatronic project; it will have a motor, gears, battery, clutch, and a generator.
The project is applicable and useful for sports activities, daily bicycle uses of transportation, and those who cycle/pedal on hills which vary in ground elevation. It is also important from the safety part, decreasing the speed while going down, and increasing the speed while going up.

Project Objectives

  • The design of an energy-efficient bicycle.
  • Reducing the required pedaling effort by utilizing a motor.
  • Converting mechanical energy from wheel rotation to electrical energy.
