I have found that these shared bikes are not for me. They are not
available where (and when) I need them. They require a smartphone with
a dedicated app to use them. Moreover, data connection is required
(they tend to place bikes in areas with no free WiFi nor the EDUROAM).
I can manage the Android device but I do not want to have (and pay
for) the mobile data thing.
So I have to use my own bike for commuting and shopping. It has better
gears, larger storage space and is always available. And it is not
pink. (And why these services tend to paint their bikes to ping or
light blue?)
