This document describes a student project to design an ergonomic bicycle drive system. The system aims to store kinetic energy from pedaling in a flywheel and release it to boost bicycle speed with less effort. It allows carrying heavier loads and making bicycling more comfortable. The ergonomic drive connects a second chainring via chain drives to transfer energy between the flywheel and rear cog for easier pedaling. Potential users include students, athletes and delivery workers. Features include gears, brakes, lights and a carrier, with advantages of lower energy input, faster travel, and improved efficiency. In conclusion, the ergonomic drive saves lost pedaling energy and has potential for further development.

3. WHAT IS ERGONOMICS ?
• The word "Ergonomics" comes from two
Greek words "ergon," meaning work, and
"nomos" meaning laws.
• Today, however, the word is used to describe
the science of "designing the job to fit the
worker, not forcing the worker to fit the job."
• Ergonomics covers all aspects of a job, from
the physical stresses it places on joints,
muscles, nerves, tendons, bones and the like, to
environmental factors which can effect
hearing, vision, and general comfort and health.

4. WHAT IS OUR PURPOSE?
• Use stored kinetic energy in to motion
energy.
• To boost the speed of bicycle with in less
energy.
• To carry more weight in bicycle’s carrier for
transportation.
• Made bicycle more attractive.
• Increase the comfort ability of user.

5. HOW CAN THIS POSSIBLE ?
• Main chainring is connected with rear cog by chain
drive.
• Second chainring which connected with rear cog, it
is also connected with flywheel by chain drive.
• Flywheel is mounted between top tube, down tube
and seat tube.
• When we drive a pedal, power transmitted to
flywheel.
• And flywheel is produced centrifugal force and get
easy drive.

7. WHO CAN USE THIS BICYCLE ?
• Students
• Athletes
• Postman
• Milk man
• Vendors
• Sales man
• Courier boy etc.

8. FEATURES OF THIS BICYCLE
• Fly wheel
• 2 speed gear system
• Brakes
• Adjustable carrier
• Light system
• Horn
• Water bottle stand
• First aid kit for any emergency

9. COMPONENTS OF THIS BICYCLE

10. ADVANTAGES OF THIS BICYCLE
• Low energy input and more work done
• Reach on time at desire location
• Easily convert from kinetic energy to motion
when need
• More comfortable
• Get more efficient work

11. CONCLUSION
Ergonomics drive system saving a part of the
energy lost after pedaling.
Ergonomics drive system has a wide scope
for further development and the energy
savings.
Here we implemented Ergonomics drive
system in a bicycle gaining much more
efficiency.
