Life tip: Noone appreciates and there's no utility in nitpicking analogies. They're never the actual point of the message and it's incredibly rude and socially inept to lock onto a side quest like that.
My own life tip: there are plenty of good analogies, so no need to choose use an example you are not familiar with.
We all see that OP does understand bikes in the general sense, indeed the fact you are nitpicking instead of trying to explain one of the many fundamental difference means you think that as well.
They're not totally without value but I find that it's generally better to avoid a analogies. Look for some other route to make the point.
They rely on the recipient going along with the analogy and trying to make it work, not trying to find problems with it. If someone understands the concept well enough to needle the analogy, they probably have a better understanding than the analogy can provide anyway, so it is fine to give it up.
In this case it is neither used for arguing, nor for explanation really, I think, but as a bit of rhetorical flair. The analogy is to an obviously stupid thing to do, throw away your bike because of some easy to fix cabling issue.
