It is because it has a commercial construction that supports a higher user weight capacity of 440 pounds/200 kg, features a magnetic resistance system and dual-sided pedals.

It is a professional spin bike that is designed to be used in commercial gyms, health clubs, cycling studios, and of course home use.

It’s an indoor cycling bike that is reliable and provides quality cardio exercises that burn tons of calories and improve general physical well-being regardless of where it is being used, by whom, or how hard it is being pushed.

It is integrated with a 35-pounds/15.8 kg perimeter weighted flywheel that provides consistent momentum and also supports the resistance system in providing challenging workouts.

Its operation is quiet because of the solid leather belt transmission.

The bike comes with two extra dumbbells which are designated behind the seat and are designed to help the user also exercise the upper body such as the arms while pedaling. The soft rubber foam-coated handlebar features four different grips for different forms of exercise.

The bike’s micro-adjustability allows users of different sizes and heights to be able to utilize it comfortably.

The Frame and Construction

L NOW Indoor Cycling Stationary Bike D501 Commercial Standard Review

The L NOW Indoor Cycling Stationary Bike D501 features commercial standard construction. For instance, the frame is made of heavy-duty steel and the crankshafts have a commercial standard build with special surface rust-proof that ensures long-term use.  

The steel frame and other metal parts are also coated with anti-corrosive paint that prevents them from rusts degradation. As aforementioned, the frame supports a high user weight capacity of 440 pounds/200 kg maximum.

The construction also includes a spring that absorbs the shock and provides an overall comfortable and smoother ride.

The bike is not foldable neither is it going to overwhelm your space because it is not too large, however, slightly larger than the other L NOW models aforementioned.

The L NOW Indoor Cycling Stationary Bike D501 has overall assembled dimensions of 50 inches long by 21 inches wide by 48 inches tall. This means that a workout area of 4’2’’ long by 1’8’’ wide will suffice, however, additional extra clearance of 1-2 feet might be necessary at the rear and on each side of the bike if it is going to be used in a confined area.

Stability is one aspect that is very important because a bike with good stability provides workouts that are void of rocking or tipping and this bike is the epitome of stability.

In other words, its stability is superlative because of its base framework that features solid steel rear and front stabilizer bars that also feature levelers underneath that allow the user to balance the bike on a surface that is crooked.

On top of that, the bike weighs about 136 pounds/61.6 kg which helps to keep it grounded even during an intense or vigorous workout.

That said, relocating such a heavy bike from one room to another could be a herculean task but it is made easy by the integrated transport wheels at the front base. You simply tilt and roll it away to and from workout and storage areas. However, you are going to need assistance if it were to be moved through the stairs.

 The Seat, the Handlebar, and the Pedals

The seat of the L NOW Indoor Cycling Stationary Bike D501 Commercial Standard is cushioned with high-quality sponge-like foam which helps to absorb shocks more effectively and significantly provides comfort to the butt for a long-term ride.

The seat is 4-way adjustable; it can be adjusted horizontally (fore/aft) and vertically (upward/downward).  

The seat can also be replaced or swapped with another type of saddle you may want to use.

The handlebar is also 4-way adjustable just like the seat. It could be adjusted forward/backward and upward and downward. This means that different users will find the bike very suitable.

The adjustment is not difficult and doesn’t take time to do either. In a situation where there are multiple users, you can easily find your previous seat and handlebar settings without hassle because there are markings on the seat and the handlebar posts.

The handlebar features four different grips that allow you to work out in a variety of postures. It is also coated with soft rubber foam that provides secure and comfortable grips. Thus, no slippage or blisters in the palms will be experienced.

There are built-in sensors on the handlebar which when gripped during a workout transmit heart rate data to the monitor so that you can keep an eye on your target heart rate zone at all times.

The pedals are dual-sided. This means that the pedals have toe cages and adjustable safety straps on one side while the reversed side is SDP compatible. Therefore, you don’t have to swap the pedals for any reason because you can use standard gym shoes or a pair of spinning shoes to exercise.

The pedals are made of solid aluminum alloy that supports a different style of pedaling or riding.

The Drive

L NOW Indoor Cycling Stationary Bike D501 Commercial Standard Review

The L NOW Indoor Cycling Stationary Bike D501 Commercial Standard is equipped with a belt drive system that provides smooth and quiet operation.

The drive system consists of a very solid automotive-grade belt that doesn’t shred or break, a 3-piece crankset, heavy-duty crank-arms, and pedals that guarantee that your stand-up ride is safe and the 35 pounds/15.8 kg perimeter weighted flywheel that provides consistent momentum. Together, these elements ensure that you experience smooth, quiet, and effective exercise.

You can work out at the time and place of your choice because no one will be disturbed by your activities. Enjoy your favorite TV show or listen to good music without having to amplify the volume more than usual.

It is also maintenance-free. The belt is tough and rugged therefore you don’t have to worry about a replacement any time soon and no lubrication or adjustment is either needed.

You will not be able to coast on the bike because the pedals and the flywheel are fixed thus they turn simultaneously. For this reason, you must push the emergency brake down (tension knob) down in order to safely stop pedaling.

The Resistance

The L NOW D501 features a manual magnetic resistance system unlike other models (as aforementioned) that have a friction resistance system instead.

This means that no friction when the resistance is engaged, no dirt or dust is generated.

The resistance is generated when the magnetic brake emits a magnetic field around the flywheel without either of the two elements being in direct contact.

The tension knob is used to increase and decrease the resistance strength. Turn it clockwise to increase the difficulty and anticlockwise to decrease it.

The resistance is suitable for everyone at any fitness level.

The resistance system does not have predefined levels like the Keiser or the ASUNA Lancer. Therefore, you increase or decrease the resistance by turning the tension knob until you feel you have the suitable resistance strength for your workout.

Comparing the highest resistance levels used between workout sessions would be problematic and this affects your ability to know the extent of your strength and endurance progress.

The Console

The L NOW Indoor Cycling Stationary Bike D501 Commercial Standard comes with an average console that features an LCD monitor that displays workout data such as time, speed, distance, calories burned, odometer, RPM, and heart rate when the EKG sensors are gripped during a workout.

The display has good readability as long as it is being used or viewed in a room that is well-lit because it is not backlit.

The console does not have special features like preset programs but you can set up workout goals for time, distance and calories.


The bike has a tablet holder for smartphone or tablet placement. It is strategically positioned so that the monitor won’t be blocked when a device is placed on it.

It is large enough to secure most smartphones and tablets.

There are also two water bottle holders for keeping water handy and within reach for hydration.


This bike is not overly large thus won’t take up space. A storage area of (dimensions) 4’2’’ long by 1’8’’ wide will suffice.

It could be stored in the garage, under the staircase, or just next to a wall.

Even though it’s significantly heavy it could easily be moved around through the integrated transport wheels at the front base.

Approval Rating

The L NOW Indoor Cycling Stationary Bike D501 Commercial Standard has a good approval rating on Amazon at the time this review was written.

The Amazon customers’ reviews indicate they were satisfied by the quality and the usability of the bike.
