cyclone

designer's own words:

In meteorology, a cyclone is an area of closed,
circular fluid motion rotating in the same direction
as the Earth. Most large-scale cyclonic circulations
are centered on areas of low atmospheric pressure.
This bicycle, named “cyclone”, has four generators
that generate powerful electricity and charge high-
efficiency batteries as cyclones in meteorology do.
These batteries and aerodynamic design make this
bicycle more efficient.
