Motorized Bicycles in Chile

The advances in batteries and efficiencies in electrical motors has caused lots of electrical driven vehicles from cars to scooters.   Old school would dictate a small 2-stroke engine (like from a chain saw) spewing smoke down the road grafted onto a bicycle frame.  If you want to get really fancy, a company could take it on and make it more professional.  While in Chile I saw several of these things and here are some pictures.  Pedal or spew smoke...your choice.
