Woodway Ecomill Treadmill Review
See treadmills here:
A concept that has been tried before and markets well but doesn't add much in regard to practical service. A machine that feeds power into your other machines or the grid is not a new idea.
If you want to pay an extra $1,000 so you can feel "green" give the $1k to a charity that benefits the environment and buy the lower priced Curve. Still no motor but $1k less and it has the same benefits to the environment.
