Fuel-cell technology, which uses pollution-free hydrogen gas to generate an electric current.
The first prototype, from Italian bikemaker Aprilia, stores compressed hydrogen in a 2-liter metal canister housed in the frame.
With a top speed of 20 m.p.h., the bike won't win the Tour de France. But it weighs 20% less than regular electrics and travels twice as far, about 43 miles, before it needs more gas.
The first bicycle is typically credited to German Baron, Karl von Drais in 1818.
Karl Drais worked on a device that he named “laufmaschine”, which is a German word that roughly translates to “running machine”.
It didn’t completely resemble the bicycle that we use today because it was made of wood, and more importantly, it had no pedals.
The machine required human force, using the feet that had to push on the ground to make the wheels begin to turn.
However, the design was the first bike like design to be publicly displayed, and was helpful to later bicycle designs.
