If you want to track your session, logging in with your username will be required. This can be done via a standard RFID login. However, if you prefer not to track your progress, you can use the machine anonymously.
Does this machine have a CE certification and comply with European directives?
This machine is currently in the process of being certified and will obtain the CE mark. It will also comply with all relevant European directives.
Who is responsible for ensuring machines comply with European directives and have a CE mark?
The manufacturer or importer of machines from outside the European Union is responsible for ensuring that the machine complies with European directives and has a CE mark. Many imported machines, for example, from the United States or other countries, may not comply with regulations. If they do not have a CE mark and do not meet European directives, they can be illegal to use.
Is the machine a medical device?
No. Medical devices are subject to extensive regulations and specific standards, which we have not included in our roadmap at this time.
Can I connect the machine to an app like XYXYX or another?
Currently, the connection with external apps is not yet available, but it is something we plan to develop. Our goal is to integrate with the most important apps on the market.
Is the Internet required for the machine to function?
The machine does not require an Internet connection to operate, but Internet access is necessary for collecting usage data, as well as for preventive and active maintenance, problem alerts, and other features. For this reason, it is recommended to connect the machine to the Internet at least once a week to sync data with a central server.
How is the resistance controlled in the machine?
The control of resistance is the result of years of research and improvement. We are proud to say that the core of our software control and regulation system is 100% custom-built from scratch. This makes our machine particularly unique, as it doesn't rely on third-party industrial software. The entire software core system is developed in Golang.
Can I use the machine by myself, or do I need a personal trainer?
Although you could technically use the machine by yourself, we do not recommend it. We strongly advise that a trained personal trainer is required to ensure you get the most out of the machine and its features.
Are there other models planned for the future?
Yes, we plan to develop other models in the future. We started with a dual cable machine, but additional models are part of our roadmap.
