Walking is our #1 family hobby. Even when our little guy is in the stroller, the fresh air is great for him. It's a good habit to start so that the older they get they are familiar with family walks (that's my theory anyway!).
Often (now this is looking back to non-winter seasons!) we walk for about an hour and stop on our route to play at a playground- so then he gets a chance to play and run around too.
The Wii is a good tool. As is just putting music on and dancing. Or doing exercise (treadmill, workout dvd, etc) while they play and do their own thing- then then see mom exercising and you are being a positive role model.
For biking, do you have a baby trailer? If you have a partner with you, you could put two trailers on - one for the 3 and 5 year old and one for the 14-month), then the 6 year old could bike beside you and as the 5 year old gets better on a bike they can get out of the trailer too. Oh and how about swimming??
