How to easily replace pedals on your mountain bike
To replace the pedals on a mountain bike, begin by removing the old pedals with a pedal wrench or hex key. Then, clean the threads on the crank arms with a cloth to remove any dirt or debris. Apply a small amount of grease to the threads of the new pedals and carefully screw them into place, using your hands to tighten them as much as possible. Finally, use the pedal wrench or hex key to tighten the pedals completely, being careful not to overtighten and damage the threads.
