3. Set-up and Operation
Unpackaging and Assembly
The medBike Whole Body Cycle ships and arrives fully assembled.
The medBike Lower Cycle requires a minimal amount of assembly. An Allen wrench, provided
within the packaged contents, is the only tool required.
Figure 3.1. medBike – packaged contents.
Begin by removing the medBike’s main pedal/arm crank/motor assembly from the packaging.
Inside the tube opening, just above the knob, there is a cable that connects the display to the
motor. Using the guide wire attached to the cable, move the cable up through the handlebars
stem tube (Figure 3.2), place the tube into the pedal/arm crank/motor assembly opening, and
affix the handlebars stem tube with a bolt using the Allen wrench (Figure 3.3).

11 Biodex Medical Systems, Inc. © 2018
Figure 3.2. Use the guide wire to move the display cable up through the handlebars stem
tube.
Figure 3.3. Use the Allen wrench to affix the handlebars stem tube to the pedal/arm
crank/motor assembly.

Figure 3.4. Handlebars stem tube--secured in pedal/arm crank/motor assembly.
Once the bottom of the handlebars stem tube has been secured, the display can be affixed to
the top. But first, the cable must be connected as illustrated below:
Figure 3.5. Connect the display cable.
Line up the holes in the back of the display with the four holes on the top of the handlebars
stem tube and affix the two pieces with the four bolts. Use the Allen wrench to tighten.

13 Biodex Medical Systems, Inc. © 2018
Figure 3.6. Connect the display.
The last step is to affix the handlebars to the handlebars stem tube. Line up the holes for the
four bolts and tighten with the Allen wrench.
Figure 3.7. Connect the handlebars.

Adjusting Pedals on the medBike
Managing the degree of hip flexion for certain patients using this device could be a concern.
First, consider moving their seat back a few inches. If the seat back reclines, consider that
option as well. The pedal crank radius is easily changed. Using the Allen wrench, remove pedal
crank bolt and move it into a closer hole on the crank as illustrated in Figure 3.9 reducing the
radius of the pedal crank:
Figure 3.9. Adjusting the Pedal/Arm Cranks using an Allen Wrench
Or, using the slim wrench included with the medBike, move the pedal to another hole on the
crank by inserting the wrench between the pedal and the crank as illustrated in the diagrams
below and unscrewing the pedal crank:

15 Biodex Medical Systems, Inc. © 2018
Figure 3.10. Adjusting the Pedal Cranks Using the Included Slim Wrench
This method avoids damaging the inner thread of the Allen bolt.
Positioning or Relocating the medBike
CAUTION: Before moving the medBike, make sure the power cord is detached. If
left attached, the cord plug will rub against the floor as the device is being moved
possibly causing black marks on the flooring.
The medBike can be moved across smooth surfaces. To move the medBike, remove the power
cord from the base of the device. Stand behind the device and lift the back end up, pivoting it
forward until the front wheels make contact with the floor. Push or pull the device to a new
location and set it down gently.
Display and Handlebars Height Adjustment
The height of the monitor display and handlebars is conveniently adjusted with the hand-turned
knob on the front of the device.
To raise or lower the display and handlebars, loosen the knob, pull up or down on the
handlebars, and re-tighten the knob.

16 Biodex Medical Systems, Inc. © 2018
Positioning for Upper Body Exercise
Loosen Adjustment knob (see Figure 3.11) to and rotate medBike upper body into desired
position. Retighten when in place.
Figure 3.11 Positioning medBike for Upper Body Exercise
On / Off
To turn the device on, press the black switch on the base.

Settings
If the device is not already set to the preferred language, make a selection on the bottom of the
screen (EN = English) and touch <Setting>.
Figure 3.13. Home screen.
Select either the <Metric> or <Imperial> setting for the preferred units of measure. Select the
maximum number of rotations per minute (rpm) for the Passive Mode. A rotation is the singular
event of moving the pedal/arm cranks all the way around a circular motion.
Figure 3.14. Settings screen.
NOTE: Although there is a Bluetooth Connection tab on the Settings screen, this feature
is not covered in this document.
Changing Pedal/Arm Cranking Directions While Exercising

18 Biodex Medical Systems, Inc. © 2018
The user or clinician may elect at any time during a session to change the pedal/arm cranking
direction from forward to reverse or reverse to forward. It is important to stop pedal/arm crank
movement completely for a few moments while the device mechanisms reset.
CAUTION: Stop pedal/arm cranking when switching between forward to reverse,
and vice versa.
Figure 3.15. Warning screen — Stop pedal/arm cranking completely for a moment before
reversing direction.
After the warning screen and countdown disappears, press the <Green Arrow> to resume the
exercise in the new pedal/arm cranking direction, or press the <Red Square> to end the
exercise.
Figure 3.16. START / STOP screen.
Spasm Control
For user safety, the medBike is equipped with a Spasm Control sensor. medBike spasm control
detects sudden twitching and/or rapid pedal/arm crank movement in opposite directions. If this

19 Biodex Medical Systems, Inc. © 2018
occurs, pedal/arm crank movement will gently cease and the screen will display an Overload!
message. A therapist is able to intervene and decide what action to take.
Figure 3.17. Spasm control warning screen.
NOTE: If pedal/arm crank rotation is completely resisted in the Passive Mode for a period of
time (about a minute), a “Motor over current protection” message may be displayed. To
protect the motor mechanism, the device will suspend operations. When this event occurs,
turn the device off with the ON / OFF switch at the base and turn the power back on.
Emergency Stop
T he medBike is equipped with an <EMERGENCY STOP>. If, for any reason, a user wants to
quickly pause or discontinue an exercise session — be it in Active or Passive mode — it can be
accomplished by pressing <STOP>. To continue exercising, <STOP> must be pressed a second
time. There is an option to resume the session or finish the session and starting a new one.
