How much of this can you just chalk up to using concrete and just copying the design of a normal bike? This is a fun art project but doesn't seem like much more

How much of this can you just chalk up to using concrete and just copying the design of a normal bike? This is a fun art project but doesn't seem like much more. Sorry for being negative about an art project. I think I was projecting my own biases, but it sounded like an engineering project and then I didn't learn anything.
