Like riding a bicycle

Beyond its literal meaning, "like riding a bicycle" carries a metaphorical weight, suggesting that some life experiences or skills become so deeply ingrained that they can never truly be forgotten. Whether it's swimming, driving a car, or speaking a language, these abilities become part of one's core identity, forming a reservoir of knowledge that persists throughout life. The phrase also implies a sense of reassurance and confidence in one's abilities. Just as one can trust in their ability to ride a bicycle, they can also rely on their capacity to navigate other challenges that they have mastered over time.
