For a sport, cycling is cheap if you cyclocommute. For transportation, personal experience has yet to save money over motoring. I don't see any break even point in near future either. Year 1 was about 2k. Year 2 has only been about $40 for a chain clean/lube kit and warm weather gloves. But even though I am trying to ride each day I can, my per mile rate is about $1.52. Motoring is about .80/mile. So I have fallen behind. Worst, got the itch to get a new bike. It'll take forever to break even.
