Two-speed Transmission via Four Pulleys diagram
Four-pulley Two-speed Drive: Ideal Ratio Comparison
Compare two ideal no-slip speed ratios and their paired pitch-diameter sums. Equal diameter sums alone do not establish that the same belt fits both positions.
Two-speed Transmission with Three Pulleys diagram
Three-pulley Two-speed Drive: Ideal Speed and Torque Ratios
Compare two stepped-pulley speed ratios and reciprocal lossless torque ratios. The schematic idler redirects the belt; belt fit, tension and shifting are not calculated.

Transmission of Two Speeds: Ideal Ratio Comparison
Compare two entered input-to-output speed ratios and their ideal torque multipliers. The calculator does not define a gearbox or simulate shifting.
