I mentioned the other day that the hook on the Mobiky's handlebar is a very useful way to carry cargo, but that because the hook is so shallow I was afraid my bag would bounce off and fall to the ground. Well, that happened this afternoon. The bag skidded on the pavement and the rear wheel ran over it, but there was no serious harm done. Does anyone know why the hook was designed with this particular shape which seems less than ideal for securely carrying luggage? I wonder if it is intended to be part of some sort of integrated system for which other components are not yet available? In any case I intend to take measures to hang my bag more securely next time.
Here is a picture of the bag as I was carrying it when it fell:
