I bought an xtracycle to get my dive gear on and gave up the technical stuff a few years ago- had kids and it got to be WAY too expensive. Freediving is much more enjoyable, cheaper, and challenging. Since I just have fins/monofin and a gear-bag to drag around, instead of some doubles and stage bottles, a bike works out nicely.
I can't admit to being car free, but I am working on reducing my carbon footprint. Giving up tech-diving, plus riding my kids around as much as possible on my bike, are all part of that.
I own a couple of dive kayaks but haven't tried to hook them up to the bike as of yet.
My father-in-law owns a charter/salvage operation in Milwaukee and I go back to work/dive with him on a, somewhat, regular basis if I need to get deeper than my local lakes allow. Another part of the allure of freediving, is that I can jump in a lake, swim all the way around it, and get out 7 hours later without ever needing a boat, or change a tank.
