Additionally, the project Abstract - This Project is entitled “Fabrication of Treadmill Bicycle". Innovative hybrid systems are a response to the growing demand for environmentally sustainable fitness and mobility options. One such idea is the Treadmill Bicycle, a novel human-powered vehicle that combines the concepts of a treadmill and a bicycle. The treadmills are not used to harness power; rather, they are fitness devices that allow us to run or walk a shorter distance while using the same principle.
seeks to create a cost-effective prototype suitable for practical demonstration and short-range human-powered mobility.
Through the concept of a treadmill, human energy is converted into motion by the machine. People can use this equipment for fitness and for short-distance transport. The system consists of a treadmill belt fixed to a frame and linked to the back wheel by a chain or gear system. The drive train spins when the user walks or runs, allowing for forward propulsion. The treadmill bicycle is environmentally beneficial because it does not utilize any organic fuels. Pollution of any kind is not encouraged by treadmill bicycles.
The Tread Mill frame supports the Belt, Rollers, and Drive Mechanism. It holds the user’s weight and maintains alignment during walking. It is a Main Component in a treadmill bicycle to carry the entire load and also transmit** power to run the bicycle.

1. INTRODUCTION Walking and cycling are two common fitness activities. A treadmill allows indoor exercise, but it limits natural movement and outdoor exposure. A bicycle enables travel, but requires pedaling power. The Treadmill Bicycle combines these two ideas into a single unit, where walking action serves as the driving unit. The project focuses on creating a lightweight system, improving user comfort, and offering an eco-friendly mobility option.
Figure 1. Treadmill Bicycle Walking Belt A walking belt is a strong rubber belt that moves the rollers to provide a surface for walking. When the user walks on the Belt that rotates smoothly, it transfers the motion to the rollers. It acts as the main moving platform in the treadmill bicycle and helps to convert the walking movement into rotational motion.
1.1 PROBLEM STATEMENT A traditional bicycle requires pedaling, and some users are not** comfortable with it. There is a need for a system that supports natural walking and still allows movement from one place to another. 1.2 OBJECTIVES The objective of this project is to develop a mechanically stable and energy-efficient Treadmill Bicycle capable of transforming linear walking motion into rotational drive. The aim includes designing a robust frame, optimizing the belt-roller mechanism, reducing frictional losses, and
