Bicycling in Ecuador

Hello all,
My wife and I are considering retiring in Ecuador within the next two years.  We haven't visited yet, we're planning on March '13 for our initial reconnaissance trip but we're having a tough time narrowing down our options.  We initially focused our attention on Cuenca, which seemed idyllic at first but I'm a little concerned we will be too cold there.  We have lived in southwest Florida for the last ten years and are pretty well acclimated to the heat.  We're currently investigating Guayaquil, which looks like a better fit for us weather-wise.  A major concern for me, however, is access to good roads for cycling.  I average about 500 miles a month of road cycling, and while I'm not expecting the wide, clearly marked bike-only lanes we have here in Florida I am hoping for a reasonable network of smooth paved roads with enough room to ride safely.  I would greatly appreciate knowing if anyone thinks the infrastructure in and around Guayaquil (or anywhere else in the country) is good enough to support my cycling addiction?  I'm thinking I'd prefer to be on the outskirts of Guayaquil with access to roads leading away from the city; I doubt I'd be able to find a place to knock out a 50 mile ride within the city limits.  All thoughts/comments/suggestions positive or negative appreciated.  Thanks in advance!
