You can get a really excellent ROI with things like kettlebells. I'd recommend the book Simple & Sinister and finding a Strongfirst coach in your area (the organization associated with the book).
If you can find a way to manage your time more effectively, barbell work is even better. Rippetoe's Starting Strength and a Starting Strength coach in your area would be your best introduction.
Not that I think you were being literal, but you don't have to ride your bike 2-3 hours per day to get the benefits of exercise. The biggest problem most people face is not knowing what to do and how to do it. The above suggestions should be sufficient to overcome that IMO.
