Would it be cheaper to download the bike route data to the device and simply do the processing there? Generally bicyclists have a fixed starting point so you could cache the results and improve them over time. (Obviously cross-country would require further work to support efficiently.) I’m all for “anything can be done in the cloud” but if the cloud can’t efficiently handle this, I still have a couple of supercomputers laying around that I’d be happy to let puzzle over my bicycling needs for a few minutes (or overnight, or for a few weeks when charging) if that helped me find a more scenic route someday that isn’t much slower than the direct one.
