Honest Review: My Experience with the Ntaifitness Superfit-8016 Assault AirBike After Trying Competing Models

When I started setting up my home gym last year, I knew I wanted to include an air bike. I've tried various models in commercial gyms over the years, from the Assault Fitness Classic to the Rogue Echo Bike, and I always appreciated the brutal simplicity of air resistance. 

It’s the kind of workout machine that doesn’t lie—you put in the effort, it gives you the punishment.

So when it came time to buy one for myself, I had a shortlist. The obvious picks were the AssaultBike Classic, the Rogue Echo Bike, and to my surprise, a lesser-known but increasingly popular model: the Ntaifitness Superfit-8016 Assault AirBike.

I had seen some early chatter about Ntaifitness on fitness forums—mostly from international buyers looking for a durable, cost-effective alternative to big-name brands. 

I decided to give it a shot and ordered the Superfit-8016 as a bit of a test run.

Unboxing & First Impressions

Right out of the box, I was impressed with the packaging. The Superfit-8016 came well-protected, with no damaged parts. 

Assembly was straightforward—nothing overly complex—and the tools were included. Total build time was about 40 minutes solo.

Visually, the bike has a solid presence. The frame is oversized and made from thick steel tubing, comparable to what I’ve seen on more expensive models. 

The welds looked clean, and there was no wobble once everything was tightened down. The aluminum alloy pedals felt premium, and the sweat-resistant adjustable seat slid easily into position without play.

Functionality & Ride Experience

What really matters, of course, is how it performs.

The air resistance system responds smoothly, and you feel the resistance ramp up instantly as you push harder. This is classic air bike mechanics, and it behaves exactly how I expected—challenging but fair. There's no resistance knob because you don’t need one; your effort is the dial.

The fan is a bit quieter than the AssaultBike Classic, though slightly louder than the Rogue Echo Bike. It's not disruptive, and if you're working out with music or a podcast on, you won’t notice.

What surprised me the most was the LED multi-screen console. It’s surprisingly good. You get your usual stats—time, calories, distance, speed, RPM, heart rate—clearly presented and easy to read during intense intervals. It doesn’t feel cheap, and the responsiveness is on par with higher-end models.

Comparing It to Other Air Bikes I’ve Tried

Let’s talk brand comparisons, because if you’re reading this, you’re probably wondering how the Ntaifitness Superfit-8016 Assault AirBike stacks up.

Vs. AssaultBike Classic: I’ve used the Assault Classic for years, and it’s a beast. That said, it’s loud, the seat wobbles over time, and the frame—while durable—has more flex than I like. The Superfit-8016 actually feels more rigid during sprints. Plus, the display on the Ntaifitness is more modern and easier to read.

Vs. Rogue Echo Bike: The Echo is overbuilt in the best way, but it’s big—too big for my limited space. Also, it’s pricier. The Superfit-8016 gives me 90% of that heavy-duty feel at about 60-70% of the cost. The Echo does edge out in terms of stability at high wattage outputs, but for 95% of users, the difference won’t matter.

What I Liked:

• Infinite air resistance system that’s as challenging as you need it to be
• Reinforced frame with zero flex during sprints
• Sweat-proof, stainless steel core saddle with both vertical and horizontal adjustability
• Surprisingly robust LED console with multi-metric display
• Compact footprint compared to Rogue but sturdier than the Assault Classic
• Affordable without feeling like a budget compromise

Room for Improvement:

• The included seat is better than most, but I’d still recommend swapping it out if you're sensitive to saddle comfort
• The brand is still growing outside of China, so accessories and replacement parts may not be as readily available as Rogue or Assault

Final Thoughts

I wasn’t expecting to like this air bike as much as I do. I bought the Ntaifitness Superfit-8016 Assault AirBike as a trial option—something that might hold me over until I decided to upgrade. But after several weeks of regular use, I honestly don’t feel the need to spend more.

It’s rare to find a commercial-grade air resistance bike for HIIT and cardio that’s built this well at this price point. For serious home users, CrossFitters, or gym owners looking to add multiple units, this could be a real value find.

I’m not saying it’s better than a Rogue Echo. But I am saying that unless you're absolutely dead set on U.S. brands or need to output 1,200 watts per sprint, the Superfit-8016 delivers 95% of the performance at a significantly lower cost.

I’ve already recommended it to two friends.
