Do bikes fly free?

Excuse me, I couldn't help but notice the intriguing question posed: "Do bikes fly free?" Now, I'm no physicist or aeronautical engineer, but my curiosity is piqued. Is this a metaphorical query about the ease or cost-effectiveness of cycling as a mode of transportation, perhaps suggesting that it's a carefree and unencumbered mode of getting around? Or is it a literal inquiry into the possibility of bicycles defying gravity and taking flight? If we're going with the latter interpretation, I must confess that, according to the laws of physics as we currently understand them, bicycles do not have the inherent capability to fly freely without some form of external assistance, such as being attached to a glider or motorized contraption. However, the ingenuity of humankind knows no bounds, and one can never say for certain what technological advancements the future may hold. But if we're exploring the metaphorical angle, then indeed, cycling can be seen as a liberating and cost-effective way to traverse our cities and landscapes, offering a sense of freedom and independence that many find appealing. So, in that sense, perhaps the question "Do bikes fly free?" could be interpreted as a rhetorical nod to the joy and liberation that cycling provides. Would you say my interpretation is on the right track, or is there another angle to this question that I've overlooked?
