When planning or upgrading a gym’s cardio zone, the type of equipment you choose can dramatically impact user experience and training results. Among the most popular machines for commercial gyms in the USA are air bikes (commonly known as assault bikes) and upright bikes. While they may seem similar at a glance, they serve very different purposes when it comes to workout intensity, muscle engagement, and overall functionality.
So, which bike should your gym invest in—the air bike with full-body resistance, or the upright bike with a classic, focused cardio approach? This guide explores the pros, cons, and ideal use cases of both, helping gym owners make a smarter equipment decision.
What Is an Air Bike?
Air bikes, or assault bikes, are a hybrid of a stationary bike and an elliptical trainer. The pedals are connected to a fan wheel, and the handlebars move back and forth, allowing users to engage both the upper and lower body.
The key feature of an air bike is that resistance increases with effort. The harder you pedal and push the handles, the greater the resistance generated by the fan. This makes air bikes particularly effective for high-intensity workouts, interval training, and metabolic conditioning.
Benefits of Air Bikes:
-
Full-body engagement: Targets arms, shoulders, chest, back, glutes, quads, and core
-
Unlimited resistance: Suits beginners and elite athletes alike
-
Ideal for HIIT: Short, intense bursts maximize calorie burn
-
Low-impact on joints: No pounding or jarring movements
-
No motor or electronics: Less maintenance over time
Air bikes have become a staple in CrossFit boxes, performance training centers, and functional fitness gyms due to their unmatched conditioning capacity.
What Is an Upright Bike?
Upright bikes are classic cardio machines found in nearly every commercial fitness facility. They simulate the experience of riding a traditional bicycle with a seated, vertical position and stationary handlebars. Resistance is typically controlled via a magnetic or friction-based flywheel system, allowing for steady-state or interval workouts.
Benefits of Upright Bikes:
-
Focused lower-body workout: Primarily targets legs, glutes, and calves
-
Adjustable resistance: Suitable for steady-state endurance or gentle intervals
-
Comfortable seat position: Great for longer rides or warm-ups
-
Compact and space-efficient: Easier to fit in tight training areas
-
Lower cost: Often more budget-friendly than performance air bikes
Upright bikes are ideal for general fitness facilities, hotel gyms, and rehab-focused spaces where moderate cardio and accessibility are a priority.
Head-to-Head Comparison: Air Bike vs. Upright Bike
| Feature | Air Bike | Upright Bike |
|---|---|---|
| Resistance Type | Air/fan-based; increases with effort | Magnetic or friction-based; preset levels |
| Muscle Engagement | Full-body: upper + lower | Lower body only |
| Workout Style | High-intensity, intervals | Steady-state, endurance |
| Ideal Users | Athletes, HIIT fans, functional trainers | General gym-goers, seniors, rehab clients |
| Noise Level | Loud due to fan | Quiet operation |
| Maintenance | Minimal (no motor) | Requires occasional calibration |
| Cost Range | Moderate to high | Budget to mid-range |
| Space Needs | Larger footprint | Compact and space-saving |
Which Bike Is Best for Your Gym?
The right choice between an air bike and an upright bike depends on your gym’s training philosophy, space availability, and member demographics.
Choose an Air Bike If:
-
You run a functional fitness or strength-focused facility
-
HIIT classes and metabolic conditioning are a big part of your offerings
-
You want to push members toward intensity-based cardio workouts
-
Your members are performance-driven or athletic-minded
An air bike delivers a killer workout in less time, making it perfect for busy professionals or group training environments.
Choose an Upright Bike If:
-
Your gym caters to a broad range of ages and fitness levels
-
You focus on long-duration cardio, warm-ups, or rehab programming
-
You want a quiet, easy-to-use machine for hotel or corporate gyms
-
You’re limited on space or working with a tighter budget
Upright bikes provide a comfortable, accessible cardio solution for the general population.
The Case for Having Both
Many successful gyms in the USA are choosing not to pick one over the other—instead, they equip their cardio floors with both air bikes and upright bikes. This gives members the freedom to choose based on their goals, energy level, or workout plan.
Offering variety in your commercial cardio equipment USA lineup enhances your gym’s appeal, supports diverse programming, and increases member satisfaction. It also positions your facility as well-rounded and modern—traits that can make a real difference in member retention and referrals.
Final Thoughts
When it comes to air bikes and upright bikes, the decision isn’t necessarily about which is better, but which is better suited to your gym’s needs. If your training philosophy emphasizes intensity, engagement, and performance, the air bike is hard to beat. If you want something that’s user-friendly, space-efficient, and great for general cardio, the upright bike is a smart addition.
In 2025, fitness is no longer one-size-fits-all—and neither is your equipment. Consider your clientele, training styles, and space to make the best investment in your gym’s future.
