M3i INDOOR GROUP CYCLE
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. See Figure 27.
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.

Six O’Clock Position.
Always secure the pedal clip strap:
1. Place the widest part of foot over the pedal.
2. Locate the strap and pull up on it to tighten.
It should be snug but not too tight to cause
discomfort.
NOTE: Pedaling at high speeds or pedaling
while standing are considered advanced
techniques, and should only be performed
by advanced users.
WARNING: The indoor cycle is NOT designed with a freewheel, but a fixed gear system. When the
flywheel is in motion, the pedals will also be in motion. Never remove your feet from the pedals
while in motion as serious user injury may occur.
