M5 STRIDER ASSEMBLY
UNPACKING THE M5 STRIDER
Step 1: Elevate the packed M5 so that the cardboard stapled to the underneath of the box is
accessible. Pry the cardboard flaps down and away from the plywood base. A standard
screwdriver may be used to pry the staples out of the cardboard and plywood. Discard the
cardboard box after removal.
Step 2: With the ratchet, 13mm socket and 13mm wrench, remove the screws securing the Top
Frame and Hanger-Pedal Mounts. The Top Frame securing screw must be accessed from the
underside of the plywood (Fig. 1). Raising the base will allow easier access to these screws.
Discard the removed screws.
Step 3: Cut all accessible straps and ties, being careful not to damage any parts (Fig. 2). Then remove
the loose parts and set aside. When cutting the ties securing the Handlebar be careful to not cut the
Computer Wire in the Top Frame.
Step 4: Remove the nut and bolt that hold the Pedal Mount stable (Fig. 3). Discard the removed
hardware.
Step 5: Carefully remove the M5 Strider from the packaging. Lay out all of the components and check
to assure all parts are present and undamaged. If parts are missing or damaged contact your local
dealer, distributor or Keiser Service Department. After unpacking and verifying parts, you are ready
to start your assembly. You need an area that is free of dirt, dust or other foreign material that could
impair the assembly of your M5 Strider.

ATTACHING THE COMPUTER
Step 1: Remove the Computer from its packaging on the Top Frame, be careful not to damage the
Computer or it’s wiring. With the #2 Phillips screwdriver remove the Computer Mounting Screw from
the Handlebar Tube (located at the top of the Top Frame). Set this screw aside for later use.
Step 2: Coil the Computer Cable into the Computer Mount Cavity (Fig. 8). Slide the Computer up into
the two tabs (Fig. 9). Insert and secure the screw removed in Step 1 using the #2 Phillips screwdriver.
Step 3: Follow this step to check your Shifter and Computer Cable Connections. Begin with the Shifter
Lever in the down position. While holding the free end of both Pedal Mounts, rotate the Cranks one
full turn or until the Computer turns on. The display will show “ODO” for 10 seconds, then cycle the
Shifter forward and backward from “GEAR 1” through “GEAR 24” (Fig. 10, next page). If gears are
displayed with no problems, the Computer is working properly. If Gears are not found check the Shifter
and Computer Cable Connections.
Step 4: Obtain the ratchet with 13mm socket, eight Hex Head Cap Screws (D2) and eight Small
Washers (C4). Secure the Top Frame to the Main Frame (Fig. 11, next page). Torque the screws to 23 Nm (17
ft-lbs), then insert the Rubber Caps (D1) into the holes of the Main Frame (Fig. 12, next page).

FINAL ASSEMBLY
Step 1: Obtain the Handlebar Assembly (A). Tilt the Handlebar Assembly slightly to place
the two Socket Head Cap Screws (D3) into the mounting holes. Once each screw has been
started, place the palm of one hand on the center of the Handlebar Assembly pressing firmly and
evenly onto the Handlebar Post (Fig. 13). Use the 6mm Allen wrench to evenly tighten the screws.
Step 2: Obtain the Handles (B) and Hanger-Pedal Mounts (F). The Handles and Hanger-Pedal Mounts
are stamped either L or R (Fig. 14 & 15). Lay them on a flat horizontal surface. Orient the HangerPedal Mounts so that the L or R stamps face the L or R stamps inside the bracket of the Handles (Fig. 16). If the Handles and Hanger-Pedal Mounts are assembled correctly, the L and R should
not be visible. Assemble handlebar to hanger pedal mount using 8 of PN 9515 with the 5mm Allen
wrench, tighten 4 screws evenly. After all screws are tight, retighten screws to ensure they did not
loosen. Follow the instructions in the supplied User Manual to assemble the remaining components.
Step 3: Using the ratchet with 13mm socket and 13mm wrench, one Hex Head Cap Screw (D4)
and one Large Washer (C5), secure the Handle/Hanger Assembly to the Top Frame. Place the
Assembly on the Top Frame with the heads of the screws (installed in Step 2) pointing towards the
user of the machine, and torque the screw to 23 Nm (17 ft-lbs). Insert the Aluminum Cap (E) into the
Handle (Fig. 17, next page), being careful not to damage the attached O-Ring. Repeat for the other
Handle/Hanger Assembly.
Step 4: Use the ratchet with 13mm socket and 13mm wrench, one Hex Head Cap Screw (C2),
two Small Washers (C4) and one Elastic Lock Nut (C3) to secure one Hanger to one Pedal Mount (Fig.
18, next page). Place one washer under the screw head and one before the nut. Torque the screw to
23 Nm (17 ft-lbs). Repeat for the other side.

NOTE: Since we are always striving to improve our products;
our products are subject to change without notice.
M5 RESISTANCE OVERVIEW
The Keiser M5 Strider is a revolutionary new way to exercise, with a focus on Power Output. The
understanding of the M5 resistance system can best be described in the explanation of eddy
current resistance and the formula for Power:
(Power = Force x Velocity).
An eddy current is an electrical current in a conducting material that results from
induction by a moving or varying magnetic field. On the M5, this is generated by the wheel
passing through two opposing magnets. The flywheel (a conductor) passes through the magnetic field
generated by the two powerful magnets. By varying how much of the magnetic field comes into
contact with the flywheel, the amount of resistance will increase or decrease for the user. This
resistance system also allows the participant a smoother, quieter, and more predictable workout.
If the flywheel is in less contact with the
magnetic field, it is easier to operate.

The more of the flywheel that comes in
contact with the magnetic field (the higher the
energy that is being generated with each turn)
the more difficult it becomes to operate.

Cutaway Revealing Magnet
Flywheel
Another major factor that plays a role in resistance is speed. The faster the flywheel turns, the more
energy is generated, and thus the more resistance is created.
Power (amount of work being done in a given amount of time by the participant) = Force (the amount
of resistance) x Velocity (the Cadence the user is striding). This is the same formula that occurs
naturally. By moving faster the difficultly increases as the resistance increases. The same applies to the
M5, at a set Gear the resistance can be increased or decreased by adjusting the participants speed.
In this way the M5 is very similar to natural movement. The higher the Gear, the higher the Cadence
the more Power produced.
M5 COMPUTER OVERVIEW
The M5 computer is a powerful teaching and programming tool. The computer can assist both the
instructor and participant by providing immediate feedback as well as tracking on-going improvement.
By experiencing objective Cadence, Power Output, Gears and Heart Rate, the participant benefits from
a better overall and more effective workout. The computer can also be used as a motivating tool to
engage participants in their workouts. The more participants understand the components of a proper
workout, the further they can fine tune their performance. The goal is to work more effectively and
efficiently, and achieve better results.
LINE 1 BACKLIGHT SENSOR
While the M Series Computer is
awake, the Backlight Sensor
automatically detects ambient
light levels in the room and turns on
the backlit display when needed.
LINE 2 RPM (CADENCE)
The RPM displays the cyclists
Revolutions Per Minute on one crank
arm. RPM is also known in the cycling
world as Cadence and is roughly the
speed at which the cyclist is
pedaling. At above 140 RPM the
computer will not read and the word
“STOP” will appear to indicate that the
cyclist is pedaling faster than he or she
needs to be. If the cyclist is out of the
saddle and wishes to retain the
sufficient resistance, pedaling should
not fall below 60 RPM.
LINE 3 POWER
The Power Output is displayed in
Watts (currently generating) and
Kilocalories (total value for the
workout). The computer toggles back and forth between Watts (displayed for eight seconds)
and Kilocalories (displayed for two seconds) throughout the ride. Rated accuracy for Power is
+5W for Power below 50W, and +10% for Power above 50W.
LINE 4 HEART RATE
If there is no Heart Rate signal, a steady heart symbol and a zero will be displayed. If a
participant is wearing a Heart Rate strap, once the computer locks onto the signal, the
heart symbol will blink and display the heart rate. Please note that the Heart Rate strap
must be Polar™ compatible and coded.
WARNING: Heart rate monitoring systems may be inaccurate. Over exercise
may result in serious injury or death. If you feel faint stop exercising immediately.
LINE 5 ELAPSED TIME
The number shown reports the total time spent cycling and will reset to zero after 60 seconds of inactivity or if computer is reset using the gear shifter.
LINE 6 GEAR
Gears from 1 – 24 are displayed on the bottom left hand of the screen.
LINE 7 ODOMETER/TRIP DISTANCE
For the first eight seconds when the computer is first activated, the Odometer will display
the total distance the cycle has been ridden. This feature is for service and maintenance
purposes only. After eight seconds, the Odometer will display Trip Distance.
AVERAGE CALCULATIONS
To view averages: RPM (Cadence), Power, and Heart Rate at any point in the workout,
stop pedaling for three seconds. This will flash your averages until you start moving again
or until the computer goes to sleep after 60 seconds.
RESETTING RIDE AVERAGES, ELAPSED TIME AND DISTANCE
To reset your averages during the workout, stop pedaling for three seconds and the
averages will start to flash, while they are flashing move the gear shifter from bottom to top
two times quickly. This will reset your workout information back to zero.
M SERIES CARDIO CALIBRATION
The Keiser M3 and M5 computer calibration procedure has changed with the addition of the
backlit display. The M3 and M5 are calibrated with a tool at the factory and there is no need to
calibrate, unless a component associated with the resistance mechanism or computer require
service. For more information visit: www.keiser.com, under “support” and “service”, or contact
the Keiser service department at 1-800-888-7009 | 559-256-8000 | service@keiser.com.
COMPUTER BATTERY REPLACEMENT
To test the computer batteries rotate the crank arm until the computer “wakes up”. If the
battery is low, a “LO-BA” will display in the Odometer (ODO) display at the bottom of the
computer. To replace the batteries unscrew the back of the computer housing and remove
old AA batteries and replace with a set of two new AA batteries. If you have multiple
machines, we suggest all computer batteries be changed at the same time.

1. Each member should thoroughly inspect each Strider to make sure it is in safe and
proper working order.
2. Each member should wipe off their own sweat after each class with a soft towel (their
towel) or cloth.
3. Check and re-torque the screw holding the crank arm to the axle. The torque for both
is 35 ft-lbs (47Nm).
4. Thoroughly inspect each Strider to make sure it is in safe and proper working order.
Pay particular attention to loose screws, nuts & bolts, crank arms, footpads,
handlebars, adjustment handles, etc.
5. Clean with warm water and a soft cloth the parts of the Strider that are dirty
or come in contact with sweat. Do not use household or industrial cleaners,
because many of them are designed to clean, glass, tile, porcelain, and greasy or oily
surfaces and can destroy the protective finish of the paint. If you need to use soap, use
a mild dish washing soap followed by an automotive treatment such as Meguiar’s Quick
Detailer Mist and Wipe.
6. Check batteries. IF YOU HAVE MULTIPLE MACHINES, WE SUGGEST ALL
COMPUTER BATTERIES BE CHANGED AT THE SAME TIME (2 AA batteries per bike).
See “Computer Battery Replacement” section for instruction.
7. It is not necessary to wax the entire machine monthly, but it is very important to wax
those areas that come in contact with sweat and that are the most vulnerable to rust. Use
an easily applied automotive treatment such as Meguiar’s Quick Detailer Mist and Wipe.
Please note that failure to apply a coat of wax to high sweat areas at least once a month
will decrease paint and frame life due to corrosion and will void the warranty.
8. Remove, clean, and lubricate the threads on the adjustment handle. Since both the
threaded stud and the threaded nut are stainless steel it is very important to keep the
threads lubricated with a heavy grease, preferably white or clear in color, such as Hydrotex MT-55 or Dow Corning 111.
