i've seen a lot of crazy contraptions associated with bikes. there are those trailers for taking your kids. there are those weird things that go on in front instead that are almost as big as the kid-size trailers. there was the candyland bike. and this guy (not really a contraption, but still associated with a bike). and then, there's the thing pictured below.
that there is an oxygen tank strapped to a bike with a hose feeding the nostrils of the rider. what's the irony here? well, what if this person were playing a pick-up game of basketball with the tank on his back? i guess i just don't associate heightened physical activity with someone who needs an oxygen tank. and there's the delicate issue of what happens in an accident and the tank regulator gets knocked off.
nonetheless, you gotta hand it to this guy. he'll use a lot less oxygen biking to the hospital (trust me, he was on his way there) than walking.
