Build a team so you aren't doing everything. :-)
When we started a bike club, we took input from a lot of folks on what it might look like, and then the core group fleshed it out based on the interests of those who were willing to make it happen. As compared to the, "It would great if you did blahblahblah?.
And most importantly keep it really simple. Once you start organizing multiple events, putting a board in to place, finding sponsors, needing insurance... it can get to be a lot of work in a hurry.
My thought: find a shop to help you organize a once a month family ride, and start there.
I helped found a mountain bike club that eventually foundered due to volunteer burnout, and possibly not meeting the community's needs, so that's my perspective.
