Not gonna lie, I would have opted for a helmet.
Artist Builds ‘Superman’ Bicycle Ridden Laying Flat On Stomach

Because dream it and you can achieve it (possibly realizing later it wasn’t the stroke of genius you originally thought it was), Italian biomedical technician and artist Alessandro Tappo spends his free time building unusual bicycles (I nap and play video games). This is an example of one such bike, which is ridden laying flat on your stomach with your feet pedaling far behind you. Is it practical? Absolutely not. Is it dangerous? There’s no question. You know, I tried Superman-ing on a regular bike once, and I have to admit, I’m lucky to be alive to try it a second time. I’m not going to though, just to be clear. My health insurance isn’t exactly what it used to be, which is active.
