INTRODUCTION
At first glance, the KingSmith W1B looks more like a piece of modern office furniture than exercise equipment. This sleek styling usually raises a red flag for us at SitZip, where our mission is to prioritize ergonomics, productivity, and joint safety over aesthetics. We were skeptical that such a design could deliver a genuine workout. However, after extensive testing, we were proven wrong.
The W1B is not just a pretty face; it is one of the best-performing desk bikes currently available for users who value real biomechanics and measurable output.
In this review, we’ll answer four key questions:
Does it actually feel like a real bike?
Can you meaningfully train or lose weight on it?
How does it compare to cheaper desk bikes?
Are there any dealbreakers you should know about?
Is the KingSmith W1B right for you?
Before diving into the details, here’s a quick reality check.
This bike is a great fit if you:
Want real cycling biomechanics, not short “toy” pedals
Plan to pedal for 1–4 hours per workday
Care about getting a real workout in
Want a desk bike that stays stable under serious load
This bike may not be for you if you:
Want the lightest or cheapest option available
Are taller than ~185 cm (6’1”) and consequently need a very high desk
If you recognize yourself in the first list, keep reading.
DISCLAIMER:
SitZip is 100% independent, avoiding all affiliate links and manufacturer bribes. Our expert cyclist verifies every bike through 40+ hours of testing, using Assioma PRO RS power pedals and physics models to provide lab-grade data on resistance, calorie burn, and joint safety rather than relying on manufacturer claims.
Assembly and Build Quality
The first thing to note is the delivery itself: the box is very heavy. You will need two people to drag it up a staircase, or you will need to slide it across the ground to get it into position.
However, once the box is in the room, the assembly itself is refreshingly straightforward. All you have to do is attach the handlebars and the pedals. The materials are rigid, high-quality plastic that feels tactile and secure, avoiding the brittle feel of cheaper alternatives.
Ergonomics and Adjustability
This is where the KingSmith W1B starts to separate itself.
A surprisingly complete adjustment system
Saddle height: adjustable
Saddle foreward/backward position: adjustable
Table height: adjustable and removable. The table is stored in the bike itself!
Foot position: Each foot individually adjustable for height.
This level of adjustability allows you to dial in a proper riding position, something many desk bikes simply don’t allow.
The saddle is comfortable enough for multi-hour sessions, and pressure distribution is well balanced. Stability is excellent, even at higher intensities.
One caveat: the integrated desk could go slightly higher. Our reviewer (183 cm / 6’) was comfortable, but taller users may find the desk position too low.
Why crank length matters
Nearly all desk bikes on the market use short crank arms between 100–120 millimeters. This reduces the pedaling range of motion, limits muscle engagement, and can feel unnatural, especially over long sessions.
We measured the KingSmith W1B’s crank length at 170 millimeters, the same length used by professional cyclists, including by some in the Tour de France.
Why this matters:
Greater range of motion
Better muscle recruitment
Higher sustainable power output
More realistic cycling feel
Low Intensity
At 60 RPM (one turnover per second) on the lowest setting, we measured 32 watts of resistance. This feels like biking at approximately 15 km/h (9.3 mph), which is perfect for typing without breaking a sweat.
High Intensity: At the highest setting, your legs must output 175 watts to maintain 60 RPM. This is equivalent to approximately 32 km/h (20 mph).
We also pushed the bike to 275 watts in a stress test. This is equivalent to cycling at almost 35 km/h (22 mph). Unlike competitors, which often slip or squeak under this load, the internals here remained smooth and silent.
Stability, Noise, and Portability
The W1B is heavy, and that’s a good thing.
Rock-solid stability, even during high-intensity pedaling
No lateral wobble or frame flex
Integrated wheels make it easy to roll around the room
Regarding noise, it is quiet enough for most offices. It is slightly louder than the desk bike from deskbike.com, but unless you are extremely sensitive to noise, it is unlikely to be a distraction.
Tracking your kingsmith w1b usage with Sitzip
Without a proper app, using a desk bike can often feel like a waste of time. Even though science confirms the health benefits, the motion is so effortless that you might not feel like you are exercising. You need an app to visualize your output and show you exactly how much work you have actually put in to validate the session.
As with other desk bikes we have calibrated, you can connect this model to the SitZip app to solve this problem.
How to Connect: Simply pick up a Garmin cadence monitor and attach it to the crank arm.
Why do this? This allows you to track kilometers driven, link a heart rate monitor, and race against friends or colleagues directly through the app. Because we have calibrated the difficulty levels for this machine, you can input the setting into the app to ensure your distance and effort stats are accurate.

our Verdict on the kingsmith w1b: ⭐️⭐️⭐️⭐️✨ (4.5/5)
Even though this thing really doesn't look anything like a bike, and there are way more "classical" models out there, this is one of the most "bike" feeling desk bikes you can find. If you want the biomechanics of a real road bike and the stability to handle a serious workout, this is the model to get.
