A new and impressive technology for electric bicycles has been developed by SiGNa. The innovative product runs on water for a distance of about 100 kilometers on a single charge.
The cells that power the bicycle use sodium silicide, a powder similar to sand. In combination with water, the substance “instantly creates hydrogen gas”, that is further on used to generate energy. Moreover, excess electricity is stored in batteries that are safe and fully recyclable.

A battery-powered bike can run on a distance of approximately 50 kilometers on a charge. The advantage SiGNa’s new bike is that the cartridges are easy to swap and don’t require stopping to recharge. The only disadvantage is that a compatible fuel-cell is yet difficult to find in stores.
In the future, the cartridges could also be used to power other means of transportation. SiGNa has already received pre-orders for the cartridges. The bikes will be available beginning next summer, according to the company.
