I have one nice way of finding best routes for bike rides. It is a mix of BRouter and Strava heatmaps. Whenever I show this to someone, they think it is really cool, but I never shared it with a world. Finally I found time to record my process. You only need Strava account and web browser to create these routes. I still think it is the best way to explore routes on desktop, but let me know if you can beat this:)
