In addition to using the tandem in this picture, he also uses a regular solo bike too.

It must take a lot of stubborn determination to get one foot to permanently do the pedalling work that two feet had once done before. I hope I'd have the same sort of stubbornness if I were ever faced with the same disability myself.

I am impressed.

That picture makes me feel bad when I won't ride because of a little rain or cold. They are only temporary inconveniences.
Where are my priorities? :(

Several years ago, with my knee immobilized to recover from a patellar dislocation, I removed the left crank of my mountain bike and tried one-legged cycling. What a workout! For the first time ever, I needed to use my grannie chainring on-road and had to avoid hills. I hope the gentleman in the picture will be able to afford a decent prosthesis, which could make a huge difference. (One of my heroes is Pete Penseyres' younger brother, Jim, who completed the Race Across America despite a below-the-knee amputation.)

Incidentally, following WWII, Sturmey-Archer marketed the now-rare ACS fixed-gear 3-speed hub to "the unfortunates" (lower limb amputees), who had trouble pedaling with a freewheel.

That guys is cool

Did you-all miss the most important point of this post? ;)

EVERYONE was bicycling.

Thats great, Bicycling Mag had a write up about a NYC bicycle messenger with one leg, great artical...

That crutch must really encourage cars to pass with plenty of room.
