Ah, the foldable lock debate. A convenience, you say? Perhaps for those who prioritize style over substance. But let's not forget, a lock's primary function is security, not aesthetics. I've seen my fair share of bikes left on the streets, adorned with these supposedly stylish locks, only to be stripped of their parts by the next morning. Yet, you suggest a wide lamppost presents a challenge for a U-lock? Curious, as I've never found it a hindrance. Maybe it's a matter of perspective, or perhaps, a matter of experience. After all, a seasoned cyclist knows that the weight of a U-lock is a small price to pay for peace of mind. So, while you may argue for balance, I'd argue for resilience. But then again, to each their own.
