This guy ( http://www.expopyme.com.mx/vpabellon.php?cat=4&cid=33373... ) started selling ice cream in a bike like this ( http://www.yesh.com/blog/wp-content/uploads/2010/05/t-370.jp... ).
He sold to the local University for about 10 years, until he got money to rent a very small place in front of a hospital.
From there he continued growing and growing and now I know they have 3 good size shops in different parts of the city.
I know because my mother has been teaching in the local Univ. for 25 years and met this guy in the beginning.

I think at the end this is what matter the most. In my home town (well... in all Mexico in general), cycling ice-cream makers do not need to comply with a lot of laws (as long as nobody dies because of the ice cream...)
