I need to turn a 24" flywheel at 500 RPM with a bicycle

Click For Summary
SUMMARY

The discussion centers on calculating the gear ratio required to turn a 24-inch, 100 lb flywheel at 500 RPM using a bicycle. A key formula provided is the gear ratio, which is determined by dividing the pedaling rate by the desired flywheel speed. For a pedaling rate of 70 RPM, the necessary gear ratio is 0.14:1. The conversation suggests considering compound gear ratios due to the large gear ratio needed for this application.

PREREQUISITES
  • Understanding of gear ratios and their calculations
  • Familiarity with bicycle mechanics and drivetrain systems
  • Basic knowledge of rotational dynamics
  • Experience with mechanical design principles
NEXT STEPS
  • Research compound gear ratios and their applications in mechanical systems
  • Explore bicycle gear systems and their configurations
  • Learn about the principles of rotational dynamics and torque
  • Investigate the design considerations for heavy flywheels in mechanical projects
USEFUL FOR

Mechanical engineers, bicycle enthusiasts, and hobbyists involved in mechanical design projects requiring precise gear calculations.

I am trying to figure out the gear ratio's needed to turn a 24", 100 lb flywheel at 500 RM with a bicycle. I can not find a formula to calculate the size gears I will need. Can anyone point me in the right direction?

Welcome to Pf! Do you know the formula for gear ratio? Is this homework? An actual design project? Where have you looked/what have you tried?
