Thanks for this feedback Pierre - glad you're enjoyign using the site. I think an Auto-Plot option "By Road Bike" would be great idea. The question is whether it's feasible. I think we could do possibly do this with the OSM routing engine we use but I don't think Google's routing service supports this option. It would also depend on the data quality on the OSM database. We'll put it on the list to look into.
Hello
Great web site I use very often for planning my bike (road and mountain bike) routes and hikes.
One of the rare issues I face is with “road bikeable” routes. I like the “road bikeable” overlay, but It happened to me several times either to end up on a gravel path (not bikeable) or (less frequently) on a road where bikes are forbidden.
Gravel path happen when I use the auto plot for “bikes”, (but apparently it is designed for mountain bikes).
Forbidden roads happen when I use auto plot for road to avoid the previous issue.
Ideas for improvement :
