The new Electrical City Car

The new City Car has been presented on december 2010 At Ara Pacis Museum

Dany project Started in the 2008 as for the intention of S. Maccagnani to develop mple and at the same time prestigious city car, capable to reach easily all the point city, including limited traffic areas.

ally the Dany project was developed with the support of Picchio, experienced  pany  on definition of car structure and dynamics.

the Design and esthetical matters was involved in the project the “Italia Design” by erano.

e 2011 the project has been collected to Belumbury in all its parts. Mechanical, etical and Electrical subject are now fully own by Belumbury, managed together in technical solution. 

e 2011 a collaboration with the Bologna University has been established for the ization of the Power Train system. The project is now successfully completed and y for production.

• DANY is a four wheel motorcycle• Homologated as L7E category • Electrical or Thermal propulsion

• The electrical version offers:
