COMPUTER DISPLAY

OVERVIEW

1. BACKLIGHT SENSOR While the computer is awake, the backlight sensor automatically detects ambient light levels in the room and turns on the backlight display when needed.
2. RPM (CADENCE) The RPM displays the revolutions per minute of the crank arm—also known in the cycling world as cadence— and is roughly the speed at which the cyclist is pedaling.
3. POWER AND ENERGY The power output is displayed in Watts (currently generating) and Kilocalories (total value for the workout). The computer toggles back and forth between Watts for eight seconds and Kilocalories for two seconds. The rated accuracy for power between 30 and 160 RPM is ±5 Watts for power below 50 Watts, and ±10% for power above 50 Watts.
4. HEART RATE If there is no Heart Rate signal, a steady heart symbol and a zero will be displayed. If a user is wearing a Heart Rate strap, once the computer locks onto the signal, the heart symbol will blink and display the heart rate. Only POLAR ® with coded GymLink heart rate sensors are compatible with Keiser M Series indoor cycles.
5. ELAPSED TIME The number shown reports the total workout time spent and will reset to zero after 60 seconds of inactivity 5 or if the computer is reset using the gear shifter.
6. GEAR Gears from 1 to 24 are displayed on the bottom left hand of the screen.
7. ODOMETER/TRIP DISTANCE When the computer is activated, the Odometer “ODO” will display the distance accrual of the bike for the first eight seconds. This feature is for service and maintenance purposes only. After approximately eight seconds the Odometer “ODO” will disappear to display the Trip units for two seconds (“USA” = Miles, “EURO” = Kilometers), followed by the Trip Distance for the remainder of the workout. Trip is a calculated distance value (flat road run) based on power production (Note: To change the Trip units, follow the instructions within the “Bluetooth 6 7 ® smart” procedure on page 18).

DISPLAY FEATURES

WORKOUT DATA
To view averages: RPM, Power, and Heart Rate, at any point in the workout, stop pedaling for three seconds. This will flash your averages until you start pedaling again or until the computer goes to sleep after 60 seconds.
INTERVAL TRAINING
To initiate an interval, starting from a high gear drop the Resistance Lever to “GEAR 1” for 1/4 of a second and lift it up to a higher gear immediately. “inL #” will display confirming the interval has started. Repeat the above steps to end the interval (“inL End” will display) and the averages for that interval will blink. Note: The averages displayed at the end of your workout when pedaling has stopped are inclusive of all pedaling times and intervals that have taken place during your workout.
Bluetooth ® sMArt ENABLED
The Bluetooth ® smart-enabled computer allows Bluetooth ® Smart Ready devices such as cellphones, tablets, and computers to gather information about your workout. M3i lite compatible apps allow data to be stored to track progress over time and make the data available to other fitness applications. Classrooms are able to utilize real-time performance tracking programs which give the entire class an opportunity to see their performance compared with other participants in the class. To receive and download workout information from your M3i lite, a Bike ID number is required, which identifies your M3i lite for individual or group Bluetooth discovery. The Bike ID number is viewable within the first eight seconds (displayed as “bid” and followed by any number 1 to 200, see Figure 14). To assign a Bike ID to your M3i lite, see the “Bluetooth ® smart” procedure on page 18. Note: Bike ID set to “0” may not be discovered by Bluetooth devices.

WARNING: Heart rate monitoring systems may be inaccurate. Over-exercising may result in serious injury or death. If you feel faint stop exercising immediately.

M3i lite BLUETOOTH ® smart

To receive and download workout information from your M3i lite to any Bluetooth ® smart device, a Bike ID number (displayed as “bid”) is required. Perform the following one-time procedure to set both the “bid” and the Trip Unit (miles or kilometers) at once. NOTE: Steps 1 through 7 must be completed within one minute.

1. Begin with the computer off and pull Resistance Lever all the way down towards you. This is GEAR “1” position.

2. Pedal 1 full revolution to change the TIME value to “1”.

3. Shift the Resistance Lever to GEAR “21” for Miles, or GEAR “19” for Kilometers.

4. Pedal 1 full revolution to change the TIME value to “2”.

5. Shift the Resistance Lever to GEAR “19” for Miles, or GEAR “21” for Kilometers.

6. Pedal 1 full revolution to change the TIME value to “3”.

7. Shift the Resistance Lever from top to bottom (GEAR “88” to GEAR “1”) for a total of 6 times.
   NOTE: If the computer shuts down at any time before Step 8, the procedure has timed out. Restart the procedure from Step 1 at a time when the procedure may be completed within one minute.

8. Confirm the Trip Unit setting:
   “USA” = miles
   “EURO” = kilometers
   Save the Trip Unit: Set GEAR to any number between 8 and 16 and allow the computer to sleep (1 minute est. time). For Bluetooth ® smart setup,  continue to Step 9 (Trip Unit will be  saved with the Bike ID in Step 9).
   NOTE: “Err#” = incorrect gear setting within Steps 3–5. Restart the procedure from Step 1 after the computer shuts down (1 minute est. time).

9. Set Bike ID (“bid”):
   increases “bid” number
   decreases “bid” number
   Set the “bid” number to any number between 1 and 200.
   Save the “bid” number: Set to any number between 8 and 16 (estimated time one minute).
   NOTE: The computer must be allowed to sleep to save the “bid” number and Trip Unit, and exit the Bluetooth ® smart set up.

HOW TO EXERCISE ON THE BIKE

The M3i lite cycle is intended for a cardiovascular workout. Special programs have been designed for group exercise environments. The bike must always be used in a supervised area under control of a trained and authorized instructor.
The following pages are a brief overview for the safe and proper operation of the bike.

RIDE SET UP

Set the three points of contact on the bike to support proper body positioning:

1. SEAT Set the Seat height to align with the top of your hip when standing beside the bike.
2. HANDLEBAR Set the Handlebar height at, or slightly above, Seat height.
3. PEDALS Place the widest part of the foot on the Pedal or clip in with cycling shoe cleats (SPD). Set the Resistance Lever to lighter gear and begin pedaling. Slow or stop pedaling and check your ride set up:
   • Knee — A slight knee bend must be present when the foot is at the lowest position. The knee must not be locked (i.e., the
   seat is too high) or have too much flexion (i.e., the seat is too low).
   • Seat Depth — The front of the knee should be in line with the widest part of the foot when the Pedal is positioned at three o’clock (away from Flywheel). Check for a slight bend at the elbows, neutral spine position, and shoulder blades are drawn back and down.

Get off the bike before you make any adjustments.
CAUTION: Ensure ride set up supports proper body positioning and all adjustments are secure before your ride. Be sure to stretch and warm-up prior to your ride to help avoid injury. Add time to cool down and stretch after your ride to reduce stiffness/soreness. Failure to follow this instruction may result in injury.

Start Your Exercise:

1. Set the Resistance Lever down and set the Pedal that corresponds to your leading leg pointing forward.
2. Clip-in, or step in, to the Pedal with your leading leg, followed by your trailing leg to mount the bike.
3. Check that the cleats are properly secured to the Pedals, or pull up on the Pedal Strap to tighten the Pedal Cage (snug to fit), before you start your exercise.

End Your Exercise:

1. Bring the Flywheel to a complete stop using the Pedals or the Resistance Lever/Emergency Brake.
2. Kick your heel away from the bike to clip out. Pedal Cage Riders: push down on the buckles to release the Pedal Strap tension.
3. Step off of the higher Pedal first, then the lower one, to dismount.

WARNING: To prevent injury, always wait until the Flywheel comes to a complete stop before you attempt to dismount the bike.

POSTURE

As in any activity, proper posture is important. The preferred riding posture is to:

• Maintain a neutral spine and slightly hinge forward from the hips.
• Keep a natural curve in the low back.
• Activate the core (midsection; deep abdominal muscles).
• Open up across the collarbones.
• Draw the shoulder blades back and down.
• Keep the elbows slightly bent when the hands are placed on the handlebar.
• Maintain good lower body alignment from the hip to the knee, down to the second toe.

RIDE POSITIONS

Observe the following suggested ride and hand positions for your desired workout. Include a variety of hand positions in combination with the cycling postures to add variety and to help prevent wrist and hand discomfort. Maintain proper ride positioning with control of both the upper and lower body for optimal cycling experience (Note: M3i bike model shown in ride positions illustrations; M3i lite ride positions are similar).

BASIC
Cadence: 60–110 RPM
Distribute body weight evenly between the Seat, Handlebar, and Pedals. The basic posture serves as a point of reference for all other riding positions.

• Keep your upper body relaxed with your shoulder girdle and neck in neutral alignment.
• Engage the core (midsection, deep abdominal muscles) with the pelvis in a neutral position.
• Knees are parallel and in line with the second toe.
• Avoid seat discomfort by ensuring your glutes shift back into the seat.

NOTE: Fine-tune the Seat or Handlebar settings for comfort and to support the basic ride position.

SEATED CLIMB
Cadence: 60–90 RPM
Add moderate to heavy resistance to simulate a hill climb. This naturally shifts the rider slightly towards the back of the seat.

• Focus on maintaining a steady cadence; avoid side-to-side body rocking by keeping even pedal strokes.
• The upper body remains relaxed; keep the core engaged.
• Keep a light grip on the handlebar; hand position 1 or 2 complements the seated climb.

STANDING CLIMB
Cadence: 60–90 RPM | Heavy 60-75 RPM | Faster 75-90 RPM
Gear up to higher resistance and transition to a standing position.
There is a natural and slight body sway to create momentum and to power each pedal stroke.

• Keep each pedal stroke smooth and fluid.
• The center of gravity is low in the body with very minimal bodyweight on the handlebar; hand position 2 or 3 complements the standing climb.
• A cadence of 60–90 RPM is recommended for climbing; varying from heavy to light resistance
• Heavy climbs: shift weight back, RPM from 60–75.
• Faster climbs: shift weight slightly forward and over the middle of the seat at 75–90 RPM.

RIDE POSITIONS (CONTINUED)

LIFTS
Cadence: 70–90 RPM
Lifts are advanced postures. Riders will alternate from seated to standing positions at the desired pace. Goal: take full advantage of body weight and strength.

• The resistance is moderate to heavy, and the lift or “attack” is short.
• Riders should lift the glutes back off the seat versus straight up, keeping the center of gravity low and back.
• No weight should be on the Handlebar; elbows in front of shoulders.
• Hand position 2 or 3 complements the lift.

TIME TRIALING

Cadence: 90–100 RPM
The time-trialing posture allows cyclists to ride slightly faster.

• The rider’s body is low and in a neutral position with bodyweight shifted slightly forward.
• The shoulder girdle and neck are in neutral alignment
• Riders should shift slightly forward in the seat.
• Hand position 4 complements the time trial; keep the elbows raised slightly off the handlebar.

PEDALING

Pedaling utilizes a series of muscle contractions and relaxations that must be coordinated and synchronized. Pedal at an even, steady pace. Be sure to recruit all of the lower body muscles at every phase of the pedal stroke for an effective workout.

Gear ranges are suggested settings to help riders meet their training goals. Instructors may use gear ranges to help direct and coach riders of varied abilities. It is important that the individual rider establish gears based on their current fitness level, goals, and ability.

MAINTENANCE

CAUTION: Routine maintenance is an essential part of maintaining the highest level of equipment safety, as well as optimal equipment performance. Immediately replace damaged, worn, or broken parts and do not use the bike until all repairs have been completed and tested by a certified Keiser technician.

PREVENTATIVE MAINTENANCE SCHEDULE

Every Workout

• Bike is properly stabilized, level to the floor (refer to “Base Stabilizer” section, page 14).
• Check that parts most susceptible to wear are not damaged or broken (Adjustment Knobs, L-Handle, Pedal Cages, Pedal Straps, and Seat Upholstery).
• Cleaning: Target areas in the sweat path with a dry soft towel or cloth.

Weekly for the 1st Month

• Check to ensure that the bike is in safe proper working order (perform the full “Proper Operation Check,” page 12).
• Check that parts most susceptible to wear are not damaged or broken (Adjustment Knobs, L-Handle, Pedal Cages, Pedal Straps, and Seat Upholstery).

Monthly

• Clean the external body/parts thoroughly, targeting areas that come in contact with sweat, using a damp soft towel and a mild detergent (neutral, non-caustic). Wipe dry the equipment.

Quarterly

• Apply wax to protect the paint finish on metal parts:

1. Wipe down and thoroughly clean the bike prior to applying wax.
2. Use an easily applied automotive treatment such as Meguiar’s ® Quik Detailer Mist and Wipe.
3. Target areas that come in contact with sweat as they are most vulnerable to rust.

NOTE: Failure to apply a coat of wax to high-sweat areas at a minimum of four times a year will decrease paint and frame life due to corrosion and will void the warranty.

Annually

• Check to ensure all external visible screws and nuts are not loose and that they are tightened.
• Check parts most susceptible to wear and replace if damaged or broken (Adjustment Knobs, L-Handle, Pedal Cages, Pedal Straps, and Seat Upholstery).
• The low battery signal (“LO-BA”) will appear on the computer display when it is time to replace the batteries (two AA batteries, refer to “Computer Battery Replacement” on page 23 for complete instructions). NOTE: For establishments with multiple bikes, replacement of all computer batteries at the same time is recommended.
• Apply LPS 3 ® Rust Inhibitor or WD-40 Specialist ® Corrosion Inhibitor to the Left Bottom Bracket Bearing and to the clip-in portion of each Pedal.
• Apply lubricant to the Adjustment Knobs:

1. Unscrew and remove the Adjustment Knobs.
2. Clean threads with a lint-free cloth.
3. Apply a moderate amount of lubricant to threads, then replace the Adjustment Knobs.

NOTE: Both the threaded stud and the threaded insert nut are stainless steel. It is critical to keep the threads lubricated with a heavy grease (preferably white or clear in color), such as HYDROTEX ® Acculube #2 or any compound with equivalent anti-wear and corrosion-resistant properties.

COMPUTER BATTERY REPLACEMENT

Do not operate the equipment during the battery replacement procedure. “LO-BA” will appear on the computer to indicate that the batteries are low and need replacement.
NOTE: If batteries are dead (depleted), the Computer Display remains blank. To replace the batteries, refer to Figure 23 and follow the instructions below (Tool required: #1 Phillips screwdriver).

1. Remove the screw that secures the Computer Display to the Display Mount (remove Media Tray, if equipped, for easy access to the screw).
2. Remove the two AA batteries.
3. Install two new AA batteries, observe the correct polarity (see +/- marks inside the battery compartment). NOTE: R6 (Zinc-Carbon) or LR6 (Alkaline) type batteries are acceptable. Do not use FR6 (Lithium) or similar type batteries.
4. Tuck the Computer Wire back into the Mount as you slide the Computer Display up and onto the Display Mount, then reinstall the screw removed in Step 1.

Immediately after battery replacement, the Computer Display enters a diagnostic mode for approximately 1 minute (system data readout, followed by a series of flashing numbers). After the diagnostic mode, the Computer Display will enter sleep mode (blank screen), and the cycle is ready for use.

CAUTION

Do not dispose of batteries in a fire. The batteries may explode.
Do not open or mutilate batteries. They contain an electrolyte which is toxic and harmful to the skin and eyes.
Replace batteries with the same number and type of batteries as originally installed in the equipment.
Recycle batteries in accordance with local recycling procedures.
