We often hear about ‘moped crime’. However as a correspondent to this blog points out, a moped is about the last thing criminals would use. By definition it has pedals (‘mo-ped’) and usually has a capacity of 50cc. This means it travels at about the speed of a bicycle, or even less with two people on board. This Wikipedia entry has a picture and all the details:
The vehicle typically used in ‘moped crime’ is a scooter, which has a bigger and more powerful engine, and looks quite different.
It does not help that the police insist on using the term ‘moped crime’ but there is nothing to stop you calling it ‘scooter crime’ or ‘ride-by crime’.
