Francisco Andres Buitrago designs these 'egronomic' bicycles. I tried them, and they are comfortable, altho they do require a bit of getting used to. The steering dynamics are very different from the bikes I'm used to.
Buitrago's bicycles can be fitted with different-sized wheels and forks of various lengths. I was concerned, however, about how well the long handlebars would withstand the stresses of use. But Buitrago says his bike has held up for years of daily use.
