I used to have a scooter - and am sure I would not have been in control of the bike with those on board. And surely I would be stopped by the Police for an insecure load on board or something!!!
I suppose thats the norm over there, and I am sure the pigs arrive ok, albeit a bit shaken sometimes.
It must be a struggle getting them on the bike - they will be heavy to lift, and surely have to be secured up there one by one, and you have to keep the moped upright?
I don't think I will be trying that method of transport
