Quite a few mountainbikers on the forum. Not sure if there is any from Zug, but I'm sure we will organise some group rides during the spring. The Zurich gang will be getting together on Tuesday evenings from next month if you fancy putting your bike on the train and going for a spin on Uetliberg with some like minded people.

Oh... and check out the trails on Zugerberg, there are some good ones up there, but its been years since I have been up there so can;t remember exactly where they are, but I think some of them are on the singletrail map.
