I would like to know if it is possible from OSM to create a map with road (not track) with a gradient color about how much the slop is. For example: color from 3% to 20% per 20m.

I live in a place where it is very flat and I am looking to train more for climbing montain on my bike. I know few climb but I want to discover more.

I would love to have all road colored like this for example:

Do you have access to the slope data or are you hoping to infer it from elsewhere? looks like one of your roads and it appears that the slope information isn't in OSM.

I though OSM have elevation data :/ Maybe instead do something base on ?

OSM doesn't have elevation data. The incline tag and similar is rarely used. You almost certainly want to look at SRTM or one of its many derivatives.

Looks like other people have tried that before. E.g. looks like a comprehensive guide how to accomplish your task.

(I haven't tried it myself. Just found it by googling)
