South America bike touring resources

I’m doing some research to do a week or two bike touring in South America, this January, and looking for resources to help planning this. It would be me on my gravel bike, and looking to rent an e-bike for my mother (65 year old in very good shape, but not a regular cyclist).

Objective is mostly to see nice sceneries (less so city touring).

If anyone has recommendations of

  • routes
  • places to visit
  • e-bike rental

I would be super glad, as schedule opened and look to leave in 3-4 weeks.

Thank you!
