Reader Klaus, who blogs over at santa66.net, does not have use of his legs, but that has not kept him from cycling - handcycling. He came up with a great hack to turn his wheelchair into a handcycle. He writes:
I'm a paraplegic in a wheelchair and I had an idea and realized it! A DIY Handcycle for the economically less fortuned wheelchair users in the world.
As a wheelchair user I know the advantage of handcycles very well and thus the plus points of my project: Low (almost no) costs, simple technology, poor roads passable, faster than a wheelchair, open source, increased living range.
The following appears on his site, in English, Spanish, and German:
Due to my paralysis, I use a wheelchair and enjoy handcycling. I would like to help other handicapped people to get the same feeling (Within their possibilities). Therefore, I put my DIY handcycle idea as “open source without commercial use of the general public” (more at the end of the text). I am thinking particularly of those more challanged wheelchair users, who can not afford a handcycle. As I use a commercial handcycle myself, my aim is not to compete with the handcycle manufacturers or their cycles.
Klaus, you rock.
