Weekend in Zurich I'd ton the two Tour de Suisse passes in Entlebuch (didn't make it last year) or roll down the hill from Andermatt (which I did twice last year). Trains to the mountains are like the tube to the Westend in London. I hope there's still snow and you can only fatty around the lake, in which case I'd ride to Grindelwald around the other lakes.
