Gymstick GB3.0 and QZ: Connected ERG Training with Smart Resistance Control
The Gymstick GB3.0 is designed for comfortable home training, with computer-controlled magnetic resistance, 16 resistance levels and a console that tracks the key information from your workout.[1]
It also supports Bluetooth FTMS and is designed to work with popular training apps such as Kinomap and Zwift.[1]
But if you want more flexibility from your bike, QZ can add another layer to the experience.
What QZ can add to the Gymstick GB3.0
QZ acts as a bridge between your exercise bike and your connected-training apps. It can receive the bike’s live workout data and make that information available in a wider training workflow.
Depending on the app and the QZ setup, you can use the GB3.0 for:
- live speed, cadence, power and resistance data;
- structured workouts that follow changing targets;
- ERG-style training, where the resistance adapts to the workout target;
- virtual rides and interactive sessions;
- a more complete record of your training history;
- connecting the bike to compatible apps without being limited to the bike’s console.
The result is a bike that can fit more easily into the way you already train, whether you prefer virtual routes, structured intervals or a simple workout with better data.
ERG training without replacing your bike
ERG training is useful when you want the workout to guide your effort. Instead of manually changing the resistance every time the target changes, the training workflow can ask for a new level of effort and QZ can translate that request into the resistance adjustments supported by the GB3.0.
This makes interval sessions easier to follow. You can concentrate on cadence and effort while the workout handles the changing resistance targets.
The GB3.0 uses 16 computer-controlled resistance levels, giving QZ a practical range of steps to use during a workout.[1] The exact feel of an ERG session depends on the selected app, the workout targets, your cadence and the bike’s own resistance response, but the goal is simple: less manual adjustment and a more consistent training experience.
Use the apps you already enjoy
The GB3.0 is already marketed with Kinomap and Zwift compatibility, and QZ expands the possible connected-training workflows around supported equipment and apps.[1][2]
Depending on your device, QZ version and app configuration, you may be able to use the bike with platforms such as:
- Zwift;
- Kinomap;
- MyWhoosh;
- ROUVY;
- Wahoo RGT;
- other apps that can connect to the virtual fitness device provided by QZ.
Each app offers a different experience. You might follow a virtual route, complete a structured interval workout, train with a video, or simply use the app as a more engaging way to record and understand your session.
QZ helps keep the bike at the centre of the setup while giving you more choice about the software you use around it.
Better visibility during every workout
A connected bike is more useful when you can see and keep the information it produces. QZ can bring your workout metrics into one place, including cadence, speed, power, resistance, distance and heart-rate data when a compatible heart-rate sensor is available.
That makes it easier to compare sessions, follow a training plan and understand how your effort changes across intervals. Instead of treating every ride as an isolated workout on the console, you can build a more complete training history.
QZ can also support broader workout workflows and integrations, including training exports and services such as Strava, depending on your device and configuration.[2]
How to check whether your GB3.0 is ready
The exact experience depends on the bike firmware, the QZ version, the device running QZ and the app you want to use.
For the Gymstick GB3.0 workflow, start with a recent QZ build that includes GB3.0 support. Open QZ, look for the bike in the device list and confirm that live data is arriving before starting a long workout.
The best first test is short and simple:
- Connect the GB3.0 to QZ.
- Confirm that cadence, speed and resistance data are updating.
- Connect your chosen training app to the QZ virtual bike when required.
- Start with a short workout or an easy interval session.
- Test a few resistance changes at a comfortable effort.
- Only then move on to longer workouts or demanding ERG sessions.
If the bike does not appear, check that it is powered on, that no other app is already using its connection, and that you are running a QZ version containing the GB3.0 support.
The key idea
The Gymstick GB3.0 is a practical home exercise bike with computer-controlled resistance and built-in FTMS connectivity. QZ can help you use that hardware in a more flexible way, connecting it to richer training workflows and making ERG-style sessions easier to explore.
You do not need to replace the bike to get more from it. Start with the apps you already like, test the connection with a short workout and build the setup around the type of training you actually want to do.
