Garmin 800 or newer 810 would be the obvious bike options. And there’s the Garmin Touring too, which is aimed towards more casual cyclists, rather than loaded with loads of training functions.
If you plot a route beforehand though, the 200 should get you by on most road rides. It’s not as good as having visible maps, but the maps are mostly used purely for a point of reference on the plotted route you’re following. For example, say there’s a fork in the road, without maps it can be difficult to determine which one to follow…usually (in my experience) until you’ve followed the wrong one. Maps make it obvious straight away. You wouldn’t want to use it in the way you’d use a map though, navigating on the fly. You’d be better off with a map…
