General Information

Fan rower vs air bike – which is better?

Fan rowers emphasize full-body endurance and technique, while air bikes prioritize explosive cardio intensity. The best choice depends on training goals, available space, and user preference.

Which air resistance machine burns the most calories?

Calorie burn depends more on effort than machine type. However, air bikes and ski trainers typically produce the highest short-term energy expenditure due to total-body involvement.

Which machine is best for home gyms?

Fan rowers and fan bikes are popular for home gyms due to lower maintenance and versatility, while air bikes suit users focused on high-intensity workouts.

How accurate is the data?

Our special algorithms ensure that the data are accurate compared with the machines used in world class competitions. You can feel confident to train professionally.

Does it save workout data internally?

Our E1, D3, D9 monitors can save the workout history internally, using the memory function.

Does it connect to apps?

Yes. Depending on the product, it connects to Kinomap, EXR, Zwift, D-Fit. Please visit the Console page for more details.

ROWER

What is an air resistance (fan-based) cardio machine?

Air resistance machines use a flywheel fan to create resistance based on how hard and fast the user moves. The faster you pull, the greater the resistance becomes. This creates a self-regulating workout that adapts naturally to different fitness levels without requiring manual resistance changes.

Is air resistance adjustable?

Our machines include a damper control that changes how much air enters the flywheel. This affects the feel of the movement rather than directly setting resistance levels like magnetic systems.

Are air resistance machines suitable for beginners?

Yes. Because resistance responds to user effort, beginners can train safely at low intensity while advanced athletes can push to high power outputs on the same machine.

Are air machines noisy?

Air machines are louder than magnetic or belt-driven equipment due to the spinning fan. However, our product designs focus on smoother airflow and reduced mechanical noise.

Do air machines require electricity?

No. Our rower, ski trainer and fan bike have generator that can self-power the monitor during the exercise. And it only requires batteries without any power supply or plugin.

What muscles does a fan rower work?

A fan rower is a full-body machine engaging legs, glutes, core, back, shoulders, and arms. Approximately 60% of the power comes from the lower body, making proper leg drive essential for efficiency and injury prevention.

Is rowing low-impact?

Yes. Rowing is low-impact and places minimal stress on joints, making it suitable for long-term training, rehabilitation, and cross-training.

How does a fan rower compare to water rowers?

Fan rowers provide consistent, measurable resistance and precise performance data, while water rowers emphasize sound and feel. Fan systems are generally preferred for structured training and commercial use.

What is drag factor on a rower?

Drag factor measures how quickly the flywheel slows between strokes and reflects airflow resistance, not difficulty level. It is influenced by damper position, fan design, and cleanliness.

SKI TRAINER

What is a ski trainer used for?

A ski trainer simulates the double-poling motion of cross-country skiing and is widely used for upper-body cardio, core strength, and endurance training.

Is a ski trainer only for skiers?

No. Ski trainers are commonly used in HYROX, CrossFit, functional training, and conditioning programs due to their high metabolic demand and upper-body engagement.

What muscles does a ski trainer work?

Primary muscles include lats, shoulders, triceps, core, and hip extensors, while also engaging the cardiovascular system intensely.

Can a ski trainer be wall-mounted?

Yes. Our ski trainers offer wall-mount brackets and tools. Ski trainer comes with two boxes, one is the main box containing the machine and the other is the standing base. You can purchase the main box only if you want to mount it to the wall.

FAN BIKE

What is a Fan Bike?

Fan Bike is a stationary cycling machine using air resistance to simulate real-world riding conditions, where resistance increases with cadence and power output.

How does a Fan Bike differ from an air bike?

A Fan Bike focuses on lower-body endurance and cadence-based cycling, while air bikes combine upper- and lower-body movement for maximum cardiovascular intensity.

What is Q-Factor?

Q-Factor refers to the horizontal distance between the outer edges of the pedal attachment points (crank arms) on a bike. In simple terms, it describes how wide or narrow your stance is while pedaling. A narrow Q-factor places the feet closer together, which often feels more efficient and natural for road cyclists and endurance training. A wider Q-factor provides greater stability and knee clearance, making it common on air bikes and commercial equipment designed for high-intensity or standing efforts. Q-factor can affect pedaling comfort, knee tracking, and long-term joint health, especially during extended workouts. While there is no universal “best” Q-factor, a well-designed bike erg or air bike balances stability with biomechanical efficiency to accommodate a wide range of users.

AIR BIKE

Why are air bikes so challenging?

Air bikes engage both arms and legs simultaneously while using air resistance that increases exponentially with speed. This makes high-intensity efforts extremely demanding.

Are air bikes good for HIIT training?

Yes. Air bikes are ideal for HIIT, sprint intervals, and conditioning due to rapid resistance response and zero impact.

Are air bikes suitable for heavy users?

Our air bikes are designed with reinforced steel tubes and frames. It can sustain up to 353 lb /160 kg user weight.
