Chain System Animation

Chain system is the core transmission of the whole vehicle.

It transmits the rotating movement from the big sprockets (which connecting to the pedal) to the two small sprockets installed on front and rear Rotating Crank Subsystem (which connecting to all legs).

Two big sprockets are assembled with two pedal subassemblies at the same time, using a sprocket spacer shaft (square-shaped, working as a step shaft).

The Number of Teeth Ratio between the Big sprocket and small sprocket determines how fast the leg rotates.

Under the same angular velocity from human feet, the less teeth the small sprocket has, the faster the legs will rotate, the faster the whole vehicle will move forward.
