This new fuel-cell powered electric bike from SiGNa features cells containing a sand-like form of sodium silicide which creates hydrogen gas when combined with water, which is then used to generate electricity. The cells are fully recyclable, hot swappable, and operate without storing hydrogen. In addition, any extra electricity produced is stored in batteries to provide that extra burst of power you need when a hill is reached. The bike can go up to 60 miles on a single charge.
The cells are currently available for pre-order, however, you’re probably in for a hefty wait.
