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 happens via 2 photo interrupter 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.

Consequences for 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 eiher 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 differences does not count nor have any effect on the training analysis. The ergomo^® system only measures the left leg as decribed above. The only reason where leg analysis are taken into account is to improve sportsman 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.

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

The delivery 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 the necessary chest belt. You may use coded and uncoded chest belts.

Do not change the input in the sub menu settings during your cycling session!

Entering any input in the sub menu settings during a ride will cause wrong calculation and wrong display of data. If you want to do any changes in the sub menu settings, you should do that before and after your cycling session or stop your ride.

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

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

1 kcal (Kilocalorie) = 4,1868 kJ (Kilojoule)

A calculation example for the ergomo^®:

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%.

=> 346kcal/0,22= 1570Kcal

This is the real energy consumption when cycling.

FAQs ergomo^® computer

How much time remains, if the battery symbol "LOW" appears on the main display?
The battery symbol "LOW" appears on the main display appears when when the remaining battery capacity is is less than 2 hours. The "sleep" mode is activated when the battery has less than 1 hours capacity. All stored data remains on the ergomo^® computer and can be transferred to your pc after the ride. The computer should be recharged when the battery low sign appears. No further rides/activities are recommended as the batteries could otherwise be damaged.

Can the ergomo^® computer be restarted, if it has fallen into the sleep mode due to the low battery capacity?
When the sleep mode has been activated due to low battery, the ergomo^® should under no circumstance be reactivated before being recharged. To recharge completely press reset button on back of computer with a paperclip until you see the ergomo^® logo on screen. Then recharge the computer for at least six hours.

I have a USB/Serial port adapter, but I still can't get the ergomo pro to talk to my PC.
1) There is a very specific “order” to plugging in the adapter in order to get it to talk to the PC and ergoRacer^®.
a)        Turn on your PC computer.
b)        Plug in your USB/Serial Adapter.
c)        Open ergoRacer^® software
d)        Confirm you have the correct Power Meter Port(Com port)
If you turn on ergoRacer^® first and then plug in the USB/Serial Adapter, then it's likely it won't find the adapter.
2) Some USB/Serial adapters will not work with some PC computers. Some customers will have to buy different USB adapters before they will find one that works with their ergomo^® pro and PC computer. If you are not able to get your ergomo^® pro to talk to the software, then it's possible that you need to buy a different USB/Serial adapter.
3) Do you have a PDA or phone or camera attached to your PC computer that is using the Com port?
If so, it's possible that you need to unplug that, and then re-boot your PC to release the Com Port. In extreme cases, you might have to actually 'delete' the Com Port, in order to get it to release. This is done in SETTINGS>CONTROL PANEL>SYSTEM>HARDWARE>DEVICE MANAGER

Is the computer sealed against water?
Yes, the housing of the ergomo^® is sealed against water/moisture.

Which averages does the ergomo^® Computer show during an intervall?
It shows the average watts. After each interval the ergomo computer also shows averages for heartrate, RPM and speed.

How long will the rechargeable batteries last for?

The rechargeable batteries of Ergomo pro will last about 23h in the online mode, in sleep mode they should last about 3 weeks. The ergomo^® spin batterybox should last approx. 300 hours.

How can the software version of the ergomo® Computer be recognized and interpreted?

Which ballbearings are used in the sensor?
The ballbearings in the sensor are sealed ball bearings.

Is the ergomo^® sport sensor (the predecessor) and the ergomo^® pro computer compatible?

To use the old sensor with the new computer the sensor has to be rearranged.

Why is the width of the 102mm ergomo^® sensor 107mm?

The smallest possible width of axis at the moment is 107mm. This is due to the necessity of measuring within the inner bearings. This version is compatible to 102mm.

What has to be kept in mind while calibrating? Before installation the K-factor (K, cal) is to be noted (written on the sensor). This is then to be fed into the ergomo^® pro computer followed by the offset. To do this the right crank is to be accelerated steadily. Best results can be achieved when the biggest chain ring is used in combination with the smallest sprocket.

Is the ergomo Sensor water safe?

It is water secured in several different ways and no moisture and dirt can get inside the sensor.
