Functional concrete bike: it exists and it's amazing

The concrete functional bike doesn't care about anything other than creativity.

It's too heavy to roll on anything other than a slow crawl

It's a security risk and the least of the comfortable or easy modes of transport

But it's amazing nonetheless, just to prove the above point: creativity is limitless.

It's also amazing because it's a concrete bike and it exists.

It's dubbed "the world's first functional concrete bike.

The description references the Icycle, the bicycle with circular saws for wheels, and the bicycle without hubs, both of which have been covered on previous occasions.
