Enjoy the Zizzo! I almost bought a used Zizzo Liberte, but there was a used Dahon Boardwalk for even less. Turns out the Boardwalk's rear wheel was trashed, but a $25 used replacement wheel from the co-op and the Boardwalk was still cheaper. The aluminum Zizzo was lighter, but not by too much.
For more speed and better climbing I ended up buying a wide-range 7-speed rear gear set, 11-32 ruined the original Neos derailleur, but I swapped it out for whatever used Shimano unit I found at the co-op. I also added bull bars.
It is a fun, fairly normal riding experience, especially compared to its little yellow 16" Dahon Getaway stablemate, also modified, but more so.
