Assistive start-up system
The Assistive start-up system provides a unique and efficient way for medical professionals to initiate the ergometer without any load at a predefined pedal speed. This innovative system accelerates the pedal revolutions from zero to the desired RPM through a motor-driven mechanism, making sure that no energy of the patient is wasted during the highest resistance of the start-up phase.
With the Assistive start-up system, test subjects can commence their exercise at the target RPM while experiencing the lowest possible load on the ergometer. To enable this functionality, the ergometer is equipped with a 7″ control unit which is a standard feature with our Rehab devices and can be added to our CPET range products.
It’s important to note that this option cannot be used in conjunction with the optional Electric Adjustable Saddle Height (#960810).
Assistive start-up system
Support for initial acceleration
This system is explicitly designed to aid individuals in achieving a specific rpm (Revolutions Per Minute) and saving energy to get assistance in the start-up phase from the ergometer. Once this rpm is attained, the assistive system seamlessly disengages, putting the responsibility on the participant to maintain the desired pace independently.
It’s important to highlight that the purpose of the system is to give a helping hand in the beginning of the exercise, and not providing continuous support throughout the entire training session. Essentially, it’s about giving an extra boost at the start, not assisting the participant during the training session.
Why the assistive start-up system?
Reliable and reproducible stress tests
The experience of professionals who calibrate many ergometers showed that the Lode ergometers are the most reliable across the complete workload and rpm range and still within specifications even after many years of intensive use.
The ergometer can be used in various ergometry settings, enabling a multifunctional deployment.
Lode is a socially and environmentally responsible company. All Lode products are RoHS/WEE compliant and Lode is ISO 9001:2015, and ISO 13485:2016 certified. All medical products comply to MDD 93/42/EEC, incl. IEC 60601-1.
Extreme low start up load
The extreme low start-up load of 7 watts and the adjustability in small steps of 1 watt make this ergometer perfectly suitable for many different applications. The standard control unit shows multiple ergometry parameters and you can determine your specific default setting and start-up menu.
Small adjustment steps
The workload of the Lode ergometers is adjustable in steps of only 1 watt. Depending on your wishes, the test operator or the test subject can adjust the workload. The steps of 1 watt are possible in the manual mode as well as within protocols.

Overcoming inertia: The key to effortless ergometer starts
One of the primary challenges encountered when using an ergometer is the initial effort required to set the flywheel in motion. Initiating this movement demands a greater force than the subsequent act of cycling itself. Once the flywheel is spinning, the task becomes more manageable, allowing individuals to maintain the pace independently.
This concept is closely tied to mass inertia, which is how much an object resists changes in its motion, especially when starting from rest. In an ergometer, the flywheel’s inertia means you need a significant initial force to overcome this resistance. As the flywheel gets moving, its inertia decreases, making it easier for people to pedal.
Frequently asked questions
What is the function of the 0-watt start up option?
To start pedalling on the ergometer can be heavy for some subjects, because it cost some strength to get the flywheel in motion. When the flywheel is up to speed less effort is necessary to keep it going. The 0-watt start up option is solely meant to overcome the heavy start with low RPMs by means of a motor drive. As soon as the ergometer is up to speed and the target RPM is reached the system stops working. In this way the test subject does not have to overcome the initial resistance of the braking mechanism and can start the test with the lowest workload at the required rpm in the normal rpm-independent mode. It is not meant to be assistive during the whole test.
Does the 0-watt start up option support the subject during the test?
No, the 0-watt start up option only supports the initial start of the test. At the moment the target RPM (adjustable between 30-80 RPM) is reached the support stops and the test subject must do it all by him/her self.
How do I start the 0-watt start up option?
The 0-watt start up option needs to be set before the test starts. After choosing manual mode, a protocol or terminal mode on the 7” Control Unit, the display will show the test view. In the left down corner the button for the 0-watt start up option is located (circular arrow). If you push on the button the window opens to set the target RPM. When the target RPM is set you close the window with the green check symbol. Now the 0-watt start up option will start to support the test subject up to the target RPM and the test can start.
Does the 0-watt up start option works with LEM?
Yes, when the ergometer is in terminal mode you can set the 0-watt start up option in the same way as working with the ergometer stand alone. If the 0-watt start up option is ready (target RPM is set) the test can be started in the LEM software.
Is the 0-watt start up option comparable with the Motomed?
The Motomed or other assistive ergometers often have different modes to assist during training. In the passive mode the devices is doing all the work, in the assistive mode the user is supported during the total training and in the active mode the user is not supported at all. In this case the assistive mode is very useful for patients who do not have enough strength to do all the work themselves. With the assistance they are able to train within their own capacity. With the 0-watt start up option only the beginning of the test is assisted, but after that all the effort is delivered by the subject.
