A twin piston power transmission mechanism with a bent link, the end of the link connecting with a cylinder is a bent arm, the link has thereon for a first piston rod and a second piston rod each a bushing hole to respectively mount a main piston and a secondary piston of a piston set, the bushing hole for the first piston rod is deviated from the shank of the link; a movable connecting piece is provided between the bushing hole for the first piston rod and the main piston to make connection of the piston with the link; when the piston is raised to an upper dead point, the accelerating power at the beginning of lowering the piston will generate a component force in a tangential direction of biased circular motion of a driving wheel by deviation of the bushing hole for the first piston rod from the shank of the link. Thereby, the driving wheel immediately obtains an accelerating power in the tangential direction, and running of the driving wheel can be smoother; power of the piston set can thus be completely developed.
