1. DESIGN AND FABRICATION OF T READMILL BICYCLE Guided by: NEVIL JOHNSON Asst. Professor Mechanical MBITS Group No. 11 Group members : BIBIN JOY MALIKUDY EBIN P BABY BRISTO BABY BASIL VARGHESE 1

2. INTRODUCTION “TREAD CYCLE “ – combination of treadmill and bicycle Treadmill in gym is stationary. Using treadmill on same place without any exposure to natural atmosphere is getting bored. Also for travelling small distances use of fueled vehicles will cause unnecessary fuel consumption and pollution. Solution for these type of problems is providing wheels to treadmill and concept is termed as ‘walking bicycle’. Bicycle modified completely, Treadmill placed in between two wheels. User walks or runs on treadmill, belt moves to rear thus motion can achieved. 2

4. OBJECTIVE Design a treadmill bicycle Fabricating the mechanism Review the total performance. Checking for the stability Reduce the emission 4

5. WORKING PRINCIPLE 5

6. The idea of walking bicycle was developed by a Dutch inventor Bruin Bergmeester . [1] Lopifit is a company that makes walking bicycles but it requires battery and motor. As the rider walks, sensors register the turning treadmill and kick the motor into gear to assist the movement and set the wheels in motion. 1 Hour bicycling burns around400 - 450 calories .[2] But 1 hour walking on treadmill burns 750 – 800 calories. Running,walking on treadmill is weight bearing exercise which burns more calories and it is good for the Bone mass. [2] LITERATURE REVIEW 6

7. METHODOLOGY Experiment Details Design Materials selected Operations done Fabrication process 7

8. EXPERIMENT DETAILS Here our concept is to make the product which is completely depends on muscle power or purely mechanical . [4] The treadmill belt moves when someone walks, it rotates the roller . The rear wheel is connected to roller via chain and sprocket thus the wheel rotates. By using suitable gears the speed is increased. 8

9. T he gears present in it provide us the speed which is required for travelling faster.[5] In future we can modify this according to various technology. 9

17. Advantages are: Less effort than convectional bicycles. [3] Exercise Fuel saving More Calories is burned. Eco friendly Pedestrians in large campuses can take benefit from this product. I t can be used as an indoor locomotive device infrastructure with large roof span i.e. malls, warehouse, open markets . If coupled with a dynamo we can charge a battery. ADVANTAGES 17

18. Cant used in hilly area Only for urban uses 18 DISAVANTAGES

19. FUTURE SCOPE Can be worked with solar energy Light weight materials can be used More gears less effort Hub motors on wheel Additional exercising accessories can be fitted 19

20. Concept is designed and fabricated Testing and analysis of project was successful with expected result It is founded that riding in hilly areas is difficult & it can be rectified by implementing electrical motor or gear system Using this we could able to burn more calorie than convectional bicycles CONCLUSION 20
