I can do better than riding a bike with no handlebars- I can split the atoms of a molecule...
Haha, my brother loves this song too. I guess it means that everything's possible because so many people nowadays have such great power to do seemingly impossible things. But with power, there comes corruption and implications on many other people.
So I guess the song's hinting at the downside to power while also showing how it has benefitted others, but it ends with something simple like riding a bike with no handlebars- a minor form of power and control, but still power nonetheless.
