The Sunny Health & Fitness SF-B1852 Cycling Bike has its flywheel at the rear just like the Keiser Indoor Cycling Bike.
It is the upgraded version of the Sunny SF-B1709; its flywheel is heavier, supports a higher maximum user weight capacity, and comes with a set of dumbbell holders.
Therefore, you can exercise the lower and the upper body at the same time if you include dumbbells (dumbbells are sold separately) in the mix.

The Frame & Construction
The Sunny Health & Fitness SF-B1852 Cycling Bike is built on a sturdy and quality steel frame that is coated with black anti-corrosion paint. There are other parts that are made of ABS materials, and such parts include the flywheel casing, the drive-train cover, and the console casing.
The spin bike supports up to 350 lbs./158.7 kg maximum user weight capacity and users that are up to 6’4’’ tall.
Due to the H-shaped robust base with adjustable levelers, users will be able to train without having to experience wobbling or instability no matter the intensity of their workout.
That being said, you may want to consider using a protective rubber mat to keep the floor protected from damage because the bike weighs about 127.6 lbs./57.8 kg.
It can easily be moved around the room via the front-mounted transport wheels regardless of its weight.
The overall assembled dimensions of the indoor cycling bike are 56.3’’ long by 21.9’’ wide by 50’’ high. Thus, the workout area required would be 4’6’’ (143 cm) in length by 1’8’’ (55.6 cm) in width, plus recommended clearance of at least 2’ around it for safety and convenient workout performance.
The Seat of the Sunny Health & Fitness SF-B1852 Cycling Bike
The Sunny SF-B1852 is equipped with a race-type saddle that features a groove for breathability. It is padded and covered with vinyl material for maximum comfort. The dimensions are 10.6’’ long by 7.1’’ wide and 2.8’’ high.
In case you wish to swap it for a wider saddle, you can because it has a standard collar-type installation system. Therefore, options are widely available online and at local bicycle shops.
It is 4-way adjustable; meaning it can be adjusted vertically and horizontally for a perfect fit. The adjustments take only a few seconds because the upright post has the adjustment levels numbered. This also lets the user quickly figure out the setting if someone alters it.
Users whose inseam falls between 28’’ to 41’’ should be able to fit in on the bike without feeling cramped or restricted. It is suggested that people that are 5’-6’4’’ tall will be accommodated on the bike.
However, to be certain, find out if your inseam (length of the inner thigh to the ankle) is supported.
The handlebar is multi-grip and ergonomically designed. It is coated with soft anti-sweat rubber foam material for a firm and comfortable grip.
There are multiple grips which include a standard grip, climbing grip, cruising grip, and close grip for different workout positions.
It can only be adjusted 2-ways (upward and downward) as opposed to 4-ways for the seat. However, since the seat and the handlebar posts are slightly slanted, when adjusted the distance between them changes from 18’’ to 22.5’’.
Heart rate sensors are integrated into the side handles so that when they are grasped during a workout the user’s pulse rate will be read and data transmitted to the attached monitor.
The pedals are dual-sided. This implies that they can be ridden with a pair of standard gym shoes or special spin shoes. One side of the pedal features a toe cage, while the other side features an SPD clip-in.
They are made of durable nylon, plastic, and metallic alloy and are attached to a strong crankset and crank arms. Hence, they are strong enough to support any user that wishes to perform stand-up pedaling.
The Q-Factor (length between the inner left and inner right pedal) is 207 mm (about 8.15 in). This is about 2’’ to 3’’ more than that of a road bicycle’s Q-Factor.
Now, the thing is that a Q-Factor of 150mm (about 5.91 in) to 170mm (about 6.69 in) would be more ergonomically efficient than those that are wider. However, most users do not consider this to be a problem or a deal breaker.
The pedals have standard 9/16’’ thread, therefore, they can easily be swapped with another set of pedals of your choice as options are widely available.
The Sunny Health & Fitness SF-B1852 Cycling Bike has a belt drive system.
The drive system comprises a durable anti-stretch belt, a pulley, and a heavy 40 lbs./18.1kg perimeter weighted flywheel. Also, the 3-piece crankset, crank arms, and pedals are all part of the drive.
Due to the belt and the heavy flywheel elements, the operation of the bike is quiet, smooth, and vibration-free. So, users will be able to work out with the bike in an apartment where people live in proximity or downstairs without invading their privacy with their activities.
The drive is bidirectional; this means you can pedal in reverse just as you could pedal forward. This allows you to diversify your workout and tone some additional muscle groups that could not have been otherwise toned.
Having said that, it is important to be careful whenever you wish to stop pedaling since the drive system does not allow you to coast on the bike. Be sure to apply the emergency stop brake via the resistance adjustment lever to prevent potential injury especially, considering that the flywheel is heavy.
This indoor cycling bike features a magnetic resistance system. It has a lever-styled resistance control that allows you to easily and quickly apply your desired resistance level.
As opposed to the Sunny SF-B1709 which has up to 13 adjustable levels, this has only 7 adjustable levels. But because of the heavy flywheel, they (resistance levels) provide a range of workout difficulties that would be appreciated by all users of different fitness levels.
The resistance levels are distinctly marked on the control lever so that you can easily apply a resistance level workout without second guessing.
No power is needed for the resistance to work because it is manually adjustable.
Moreover, the advantage of this type of resistance system is that it does not wear internal parts out during the process of generating resistance. Magnetic fields are simply released around the flywheel by magnetic brake pads and thereby causing a drag that ultimately creates resistance.
So, no part replacement or maintenance will be required as time goes on, and the operation of the bike remains quiet and smooth.
Finally, a set of dumbbell holders that could support 16 lbs./7.25 kg dumbbell apiece are included. Therefore, you will be able to also exercise the upper body as you get down with the lower body.
The console is very much like the one on the Sunny SF-B1709. It features a nonbacklit LCD monitor that tracks Time, Target Time, Distance, Target Distance, Speed, Average Speed, Max Speed, Cadence, Average Cadence, Max Cadence, Race, Calories, Pulse, and more via its multiple display windows.
The Speed and Distance are measured by mph and miles by default and can be toggled to km/h and km if you want.
Countdown goals for Target, Time, Distance, and Calories can be set.
Pulse rate data is displayed when the handles with the heart rate sensors are grasped during a workout. The console is not telemetric, thus, cannot sync with a wireless HR chest strap.
2 AAA batteries power the monitor, and it turns on when you start pedaling and automatically turns off when activity ceases for a few minutes.
If the display is hard to discern or shows inaccurately, try changing the batteries.
However, the display must be viewed in a well-lit room for good readability because the monitor is not backlit.
There is a water bottle holder and a tablet holder for hydration and maintenance purposes.
Users can place a device on the tablet holder so that they can watch a workout or entertainment video. They will also be able to keep water within reach for the maintenance of proper hydration during workouts.
The bike is not very large; thus, it won’t overwhelm your space. A storage area with measurements of 4’6’’ (143 cm) in length by 1’8’’ (55.6 cm) in width will suffice.
Regardless that it weighs 127.6 lbs./57.8 kg, the user can easily have it rolled over to the storage area via the integrated transport wheels at the front base.
There were hundreds of user reviews on Amazon at the time of this review, and its overall approval rating was impressive. Therefore, this indicates that the majority of the users approve of the cycling bike.
