IMPORTANT PRECAUTIONS
WARNING: To reduce the risk of serious injury, read all important precautions and
instructions in this manual and all warnings on your exercise bike before using your exercise bike.
ICON assumes no responsibility for personal injury or property damage sustained by or through the
use of this product.
1. It is the responsibility of the owner to
ensure that all users of the exercise bike are
adequately informed of all precautions.
2. Before beginning any exercise program,
consult your physician. This is especially
important for persons over age 35 or per-
sons with pre-existing health problems.
3. Use the exercise bike only as described in
this manual.
4. The exercise bike is intended for home use
only. Do not use the exercise bike in a com-
mercial, rental, or institutional setting.
5. Keep the exercise bike indoors, away from
moisture and dust. Do not put the exercise
bike in a garage or covered patio, or near
water.
6. Place the exercise bike on a level surface,
with a mat beneath it to protect the floor or
carpet. Make sure that there is at least 2 ft.
(0.6 m) of clearance around the exercise bike.
7. Inspect and properly tighten all parts each
time the exercise bike is used. Replace any
worn parts immediately.
8. Keep children under age 12 and pets away
from the exercise bike at all times.
9. Wear appropriate clothes while exercising;

10. The exercise bike should not be used
by persons weighing more than 253 lbs.
(115 kg).
11. Be careful when mounting and dismounting
the exercise bike.
12. Always keep your back straight while using
the exercise bike; do not arch your back.
13. The exercise bike does not have a freewheel;
the pedals will continue to move until the
flywheel stops. Reduce your pedaling speed
in a controlled way.
14. To stop the flywheel quickly, press the
resistance knob downward.
15. When the exercise bike is not in use, tighten
the resistance knob completely to prevent
the flywheel from moving.
16. To avoid damaging the brake pads, do not
lubricate the brake pads.
17. Over exercising may result in serious injury
or death. If you feel faint, if you become short
of breath, or if you experience pain while
