Keiser m5, User Manual

OPERATION TEST

Your Strider should now be ready to test its operation.

1. Adjust the Handlebar for proper height and comfort. 
2. Move the Shifter downward for the least resistance, then move the Pedal          

nearest to you to the lowest position. 
3. Step onto the Pedals, lowest Pedal first and begin pedaling. 
4. The Computer should turn on and display “ODO” and total distance ridden    

across the bottom. After approximately 10 seconds “ODO” will change to  
    “GEAR” and “TRIP”. 
5. Now move the Shifter up and note the gear changing on the Computer and the  

    resistance increasing. 
6. Operate at various speeds and resistances to check for noise and vibration. 
7. Slowly move the Shifter to full forward position to check that the emergency   brake 
stops the Flywheel from turning and the display flashes “88:88”. 
8. The test is complete, please enjoy your workout.

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.

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.

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.

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.

If the flywheel is in less contact with the  

magnetic field, it is easier to operate.
