The initial investment and add-ons that some may consider a necessity can get pricy. But after all of that is bought the act of cycling itself is free or very inexpensive. Golf has all the same initial investment in equipment and gear and you still have to pay EVERY TIME you want to go golf unless you have a private golf course.
