Calculating Speed And RPM With A Lot Of Help From Baker Drivetrain

Very few bikers and custom builders are inclined (able?) to do the mathematical reasoning necessary to predict Torque, RPM and Speed. There are very few men in the industry who are making a living using abstraction and science to improve the art of multiplying torque, of optimizing gear ratios and sizes to the desired RPM versus Speed performance for the long haul. Bert Baker is one of them excelling at mastering the math to help you ride in the best range you may wish. And to prove it once again, his company Baker Drivetrain Website gives you the formula to find out yourself the perfect balance between the motor procket, the transmission gearset, the transmission pulley/sprocket, the wheel pulley/sprocket and the wheel size.     

The fundamentals of this mastery reside with the following two equations: RPM = (S × Sr × Pc × G × 88.00) ÷ (Tc × Sf × Pm) Speed = (RPM × Tc × Sf × Pm) ÷ (Sr × Pc × G × 88.00). Use the featured diagram to determine what your speed or RPM will be. And if you are allergic to math, you can launch the Speed/RPM Calculator and fill up the blanks. You will get ready-made answers. Need more info? The boys at Baker Drivetrain can recommend some proven examples that may apply to your configuration. Just call toll free 1-877-640-2004. Baker Drivetrain.
