(Romanian(?)) expression akin to "Running on paddlers' fins"?

Adding swim fins make a swimmer a more efficient swimmer. But donning them before a track event would be a disaster. The efficiency in one arena becomes a burden in another.

The bicycle is efficient; perhaps the most efficient mechanism ever devised.

Like a fish needs a bicycle

Since it does not have legs and cannot pedal, a fish would gain no mechanical efficiency from the bicycle.

The expression like a fish needs a bicycle is a funny idiom to visualize, and it’s easy to figure out when you think about it.

Does a fish need a bicycle? Not at all.
