Moto Knee, from Biodapt in Pillager, Minnesota, uses hydraulic components to provide the strength and agility needed for intense physical activity, from skiing to mountain biking.
- For better range of motion, the linkage system provides resistance when the knee is flexed up to 135 degrees -- about the position of a leg squatting on a bike or snowmobile. Many other artificial legs only allow a range of 90 degrees.
- For improved tension, its mountain-bike shocks add resistance. The aluminum and steel leg keeps the mechanized muscles clenched -- which is necessary for riding -- rather than loose, like when you're walking.
Biodapt founder Mike Schultz used the first Moto Knee to replace the leg he lost in a 2008 competitive snowmobiling accident. Here’s a video of Schultz’s story. He’ll be competing in a motocross race for amputees at the X Games in Los Angeles.
