I bought my City-El 3-wheel EV in Cupertino in 2007: and sold it in 2010- and first thing that happened within months is the drive belt snapped and the new owner emailed me "S happens" Nothing I could recommend with German serpentine belts. "Oh well... " That was it- nothing more.
This morning on a TV show - there it was - right back in Cupertino! [ video ]:
