Apply a rust and corrosion inhibitor to the Left Bottom Bracket Bearing and to the clip-in
area of each Pedal (recommended after assembly and annually thereafter, see Figure 6).
When all assembly requirements have been met, and you have read and understood
the Important Safety Instructions, test ride the bike. Fine-tune and adjust the Seat and
Handlebar height/depth and Base Stabilizer as needed. It is recommended that the bike
be pedaled in the forward direction.
Proper Operation Check:
• All Screws are tightened or torqued properly (refer to “How to Assemble the M3i Bike”
section, beginning on page 10, Steps 2 — 12).
• The Computer Display powers ON (pedal one full revolution) and the Resistance Lever
cycles GEAR 1—24 (GEAR 88 = Emergency Brake).
• Bike is properly stabilized, level to the oor (refer to “Base Stabilizer” section below).
• The Seat and Handlebar height/depth are properly set (refer to “Seat/Handlebar Height
Adjustment Knob” and “Seat/Handlebar Depth Adjustment L-Handle” sections, page 15).

BASE STABILIZER
To position the bike at the desired location refer to Figure 7 and
follow the instructions below:
Be sure there is a minimum of 24 inches (610 mm) free space
for the bike on all sides before placement.
1. Grasp the Handlebar with both hands.
2. Tilt the bike toward you until the Transport Wheels contact
the oor.
3. Roll the bike to the desired location; tilt it slowly away from
you to set down.
The bike must be placed on a at, level surface. If the sub-oor is not
level, the Base Stabilizer allows for stabilization.
To stabilize the bike, refer to Figure 8 and follow the instructions
below:
1. Hold the Seat steady, then with your foot, swipe the Base
Stabilizer counter-clockwise to drive it back into the base. This
will un-stabilize the bike.
2. Slightly push across the Seat, until the Base Feet at all three
corners contact the oor, then hold.
3. With the three Base Feet making contact with the oor, swipe
the Base Stabilizer clockwise with your foot until the Base
Stabilizer makes contact with the oor. This will stabilize the
bike.
Test for stability. The bike should sit at without rocking. Adjust and
ne-tune the Base Stabilizer as needed.
NOTE: The bike should not be used until it is stabilized. If the bike is
moved to a different location, adjust the Base Stabilizer as needed
to stabilize the bike.
WARNING: To reduce the risk of serious injury, read all important precautions and instructions in this manual
and all warnings on the bike before operation. Failure to perform the Proper Operation Check prior to operation of
the bike will void your warranty and could result in serious injury.

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.
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.
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.
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.
ELAPSED TIME The number shown reports the total workout time spent and will reset to zero after 60 seconds of inactivity
or if the computer is reset using the gear shifter.
GEAR Gears from 1 to 24 are displayed on the bottom left hand of the screen.
ODOMETER/TRIP DISTANCE When the computer is activated, the Odometer “ODO” will display the distance accrual of the
bike for the rst 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 (at road run) based on power
production (Note: To change the Trip units, follow the instructions within the “Bluetooth®smart” procedure on page 18).

OVERVIEW
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 ash
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 conrming 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 compatible apps allow data to be stored to track progress over time and
make the data available to other tness 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, a Bike ID number is required, which identies your M3i for
individual or group Bluetooth discovery. The Bike ID number is viewable within the rst eight seconds (displayed as “bid”
and followed by any number 1 to 200, see Figure 14). To assign a Bike ID to your M3i, see “Bluetooth®smart” procedure on
page 18. Note: Bike ID set to “0” may not be discovered by Bluetooth devices.

HOW TO EXERCISE ON THE BIKE
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 t), 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 rst, then the lower one, to
dismount.
The M3i cycle is intended for 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.
POSTURE
RIDE SET UP
WARNING: To prevent injury, always wait until the
Flywheel comes to a complete stop before you attempt to
dismount the bike.
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.
Set the three points of contact on the bike to support proper body positioning:
SEAT Set the Seat height to align with the top of your hip when standing beside the bike.
HANDLEBAR Set the Handlebar height at, or slightly above, Seat height.
PEDALS Place the widest part of the foot on the Pedal, or clip in with cycling shoe cleats (SPD). Set the Resistance Lever
to a 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 exion (i.e., the seat is too low).
• Handlebar Depth — Ensure setting supports a comfortable riding position: slight bend at the elbows, neutral spine
position, and shoulder blades drawn back and down.
• 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).
Get off the bike before you make any adjustments.

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. Figure 15. Proper Riding Posture

M3iINDOOR GROUP CYCLE 20
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.
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.
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 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 a 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 uid.
• The center of gravity is low in the body with very minimal
body weight on the handlebar; hand position 2 or 3
complement the standing climb.
• A cadence of 60–90 RPM is recommended for climbing;
varying from heavy to light resistance
• Heavy climbs: shift weight back, 60–75 RPM.
• Faster climbs: shift weight slightly forward and over the
middle of the seat at 75–90 RPM.
