OP asked "Has anyone else come to cycling after quitting other sports?"
Although I did ride a bike occasionally, I have done more since giving up canoeing\kayaking about 3 years ago.
Another poster mentioned how kitesurfing took up a lot of time, and for me canoeing was the same. The total time away from home, even for about an hour's paddle on a local river, amounted to half a day away from the family, and I no longer felt I could justify the time. By contrast, I could get on the bike right outside our front door, ride for an hour, and be back home at the end of the hour. A quick shower and I was available for other family duties straight away.
