Check out our shop or give us a call at (877) 698-5835. All products are available and viewable on our site.

What replacement parts are available?

The following replacement parts are available seperately:

  • ergomo® datalink
  • ergoRacer® Software
  • ergomo® sensor tool
  • ergomo® handlebar mount
  • ergomo® loading device with micro-contoller
  • ergomo® carbon crank set
  • ergomo® coded Polar heartrate belt
  • ergomo® USB Adapter
  • ergomo® Computer
  • ergomo® Bottom Bracket Sensor

How often do I have to recharge the Ergomo battery?

The original batteries hold a 30-hour charge. The Ergomo will display an empty battery icon on the CPU when it is time to recharge the battery. The battery takes several hours to charge and if you're using the newest Ergomo battery charger, there are indicator lights letting you know when the Ergomo CPU is charged.

How do I view the average and maximum functions for all of my data?

To view the average and maximum functions for all of the data ranges, press the bottom button briefly when the computer is in its regular display mode. Each press will bring you to a different screen displaying maximum, average, and real time readouts for all of the data on the Ergomo.

How do I reset and clear the Ergomo Pro before I ride again?

Once you have downloaded your data to your computer, press and hold the bottom button for 2 seconds to get to the main adjustment screen. This screen displays from top to bottom: Interval/Delete Trip/Settings/Back. Use the bottom button to highlight "Delete Trip,choose that with the top button,change the menu choice at the bottom to "Reset" and hit the top button. This will clear the data and reset the Ergomo CPU, but the file will still be able to be downloaded.

How do I install the Ergomo Bottom Bracket Sensor?

Installing the Ergomo Bottom Bracket Sensor is straightforward but, does require a few specialized tools and good knowledge of bike maintenance..

Here are the tools needed:

  • The Ergomo bottom bracket tool provided with your purchase
  • An 8mm Allen Wrench
  • A two prong, crank cap remover
  • Zip ties (provided with purchase)
  • Grease (for the Bottom Bracket)
  • A Torque Wrench with 32 mm socket.
  • A facing and tap tool set to face and chase the bottom bracket.

Installation Instructions:

Follow the specific instructions found in the installation guide and owners manual.

What is the offset?

The offset is a setting on your Ergomo CPU that allows you to calibrate the bottom bracket for minor changes due to temperature and slight mechanical changes. This shoul be adjusted once weekly, or if moving the bike from different temperature extremes, i.e. indoors to outdoors.

How do I adjust the offset?

  • To adjust the offset, place your computer in the handlebar mount and set the bike in a trainer without resistance or in a work stand allowing the wheel to spin freely.
  • Put your gearing into the highest possible gear ratio, (usually a 53:12), being the big ring in front and the smallest cog in back.
  • Connect the Ergomo Pro CPU to the data transfer cable.
  • Press the bottom button to bring-up the main settings display. The choices there are: Interval/Delete Trip/Settings/Back. Choose "Settings" with the top button.
  • Press the top button with "Bike" highlighted. Move to  "Offset Sensor" using the bottom button, then choose that using the top button.
  • The CPU will prompt you on how to run the offset sensor program. Be sure to turn the cranks from the right-hand/drive side of the crankset.

Is the heart rate signal coded? Which chest belts can be used?

The ergomo® pro system doesn't include a chest belt. But ergomo® pro and spin are both equipped with a coded Polar chip so, coded transmission is possible if using a chest belt. You may use coded and uncoded chest belts.

How does the measurement principle work and is there a deficit in measuring only one leg's work?

Measurement principle:

ergomo® measures the torsion of the bottom bracket axle. This happes via 2 photo interrupters which are built into the bottom bracket. Both light sensors use 72 points of measurements per rotation to measure the torsion of the axis. The 72 points of measurement (360°/72=5°) are provided by perforated discs. These discs are connected tightly with the axis on the inner side of the bottom bracket. Is the axis twisted slightly due to the force pushing down on it, the perforated disc shifts in the same way. This shift in position is measured through the affore mentioned 72 points of measurement. So you see: the further the shift, the further the torsion meaning more pedalpower. With the simple formula of physics: Force = Pedalpower * Frequency, one can easily measure the workload in watts during cycling.

Through the forces used while cycling and the the way these forces are measured only the power used on the left pedal can shown. The left pedalpower is transferred through the crank and the axis to the right crank, from where it uses the chain to get to the backwheel. The forces form the right side don´t lead to any torsion in the axle.

Affect on training:

The aim of watt aided training is to improve your personal skills. All improvements are relative differences to a certain starting level. These can be measured either on the left or right leg and the result will be approximately the same for healthy people. So measuring the watts on the left or right side brings no differences in the analysis.

Nearly everybody has different absolute power in the left and right leg (0-5% difference). As long as you always compare the values of the same leg the difference does not count nor have any effect on the training analysis. The ergomo® pro system only measures the left leg as decribed above. The only reason where leg analysis are taken into account is to improve the athlete at the highest level or to help someone after injuries. These tests are always made on statonary bikes and not at mobile systems like the ergomo. If any differences are registered, they can be reduced through muscle training.

Summary:

The ergomo® pro system is a perfect partner for your training and competition because you can control improvements. Also you can target your personal goals. Analysis on discrepances between the two legs are just for optimizing your personal muscle constitution.

How is the energy consumption taken into account in the ergomo® cpu?

Energy consumption shows the amount of energy an athlete is spending.

  • A calculation example for the ergomo®: 1 kcal (Kilocalorie) = 4,1868 kJ (Kilojoule)
  • At a mechanical effort of 1420 kj you have 346 kcal. For this conversion, the ergomo® takes a certain efficiency factor into account, because not the whole energy is used for the effective work. The athlete loses energy e.g. for transpiration and metablolic reactions as well. This efficiency factor in the ergomo® is 22%.

    This is the real energy consumption when cycling: => 346 kcal / 0,22 = 1570 kcal
