URL for viewing Custom Display modes > view mode

I have a single content type product with fields like price and downloads, I want a page for description and price and another page for downloads.

so far i have
Created content type with both price field and downloads field.
Created a custom view mode( Display modes > view mode) for price called ‘price’
Created another custom view mode for downloads called ‘downloads’
disabled download field from ‘price’ view mode
disabled price field from ‘downloads’ mode

default or full content view modes can be seen by visiting /node/nodeId
my question is how do i view other view modes?
