I was rather surprised to see the desk bike riding, not quite sure how I feel about that. 14 miles isn't very far to ride a bike, (that's not even 2 hours at a slow pace), so they aren't getting much benefit and despite what they claim, they are distracted. That was one of the issues with the treadmill desks. Riding a bike to and from work or taking a spin class would be more effective and healthier.
Providing a gym or fitness facility is a no brainer though. Given the modern sedentary lifestyle and physical fitness requirements it's money well spent.
