M3i INDOOR GROUP CYCLE
OPERATION
1. Stand beside the cycle, close to and beside the seat of the cycle.
2. Position the seat so that the top of the seat is level with the crest of
the hip.
3. Sit on the seat with the balls of the feet over the center of the pedals.
4. Begin to pedal very slowly.
NOTE: When the foot is in the six o’clock position there should be a slight bend
in the knee.
WARNING:
• Maximum weight of the rider shall not exceed 300 lbs (136 kg).
• If the hips rock back and forth with each pedal stroke, the seat position may be too high. Uneven
rocking from side to side may result in hip or back injuries.
• If a participant’s knees are bowed outward (beyond their normal ergonomic position), the seat
may be too low. If the knees are too flexed, unwanted stress is placed on the knee caps. The knee
should never be in an overextended position.
WARNING: Seat height adjustment shall not
exceed the mark “STOP” indicating minimum
insertion depth for safe operation.
