quately informed of all precautions.

consult your physician. This is especially
important for persons over age 35 or per-
sons with pre-existing health problems.
3. The exercise bike is not intended for use by

bike by someone responsible for their safety.
4. Use the exercise bike only as described in
this manual.
5. The exercise bike is intended for home use
only. Do not use the exercise bike in a com-

6. Keep the exercise bike indoors, away from
moisture and dust. Do not put the exercise
bike in a garage or covered patio, or near

7. Place the exercise bike on a level surface,
with a mat beneath it to protect the floor or
