- A) Bike without exchange gears Place left crank in forward level, apply the force of 1500N to the center of the left pedal, straight down the left crank for 15 seconds.As a result of the freewheel assembly status and driven structure of the tensile, bending, etc., re-continue to test by back to level or higher level position when the crank rotation above 30 degrees Carry on the same test on right crank after the left test finished.
