Few days ago I visited a bike shop of a friend, here in Turin Italy.
By chance the oldest Strida of Turin was there because of a flat tire.
That bike is more then 10 years old. The owner uses it fairly frequently to scoot around in the traffic decongestion area and parking his car outside the decongestion area (way smaller then the one of London, by the way). We are pretty sure that that bikes has 5000+ fold unfold sequences.
The buddy said that the bike showed up only few times for some minor repairs. Basically the Strida 1 is very reliable. All plastic were the original ones, including wheels. The belt also is the original one.
