The Rhine itself is fairly dull along that stretch. From Strasbourg to Mulhouse I'd stick to the foot of the Vosges, around Colmar/Ribeauville/Molsheim. https://www.alsace-wine-route.com/en/alsace-wine-route-and-cycle-route-map/
Two days ride in the other direction up the Rhine you get to Schaffhausen and the Rhine falls, which are worth a look.
