SF-B2883 Frame Construction
The Sunny SF-B2883 upright bike is an exercise bike made for home use, it features a durable steel frame with 240 lbs (109 kg) weight capacity. Furthermore, it has a thick steel tubing frame, while ABS shields cover the base and resistance elements. In addition, all the metallic parts in the bike’s frame construction come with a corrosion-resistant black paint finish.
Like other upright bikes in this feature range, the Sunny SF-B2883 has a small footprint. It takes approx. 34″L x 22.5″W (86 x 57 cm) of floor space, while the top of the handlebar reaches approx. 55.5″ (141 cm) above floor level. However, leaving at least two feet of clearance around it is advisable for easy access and unhindered usage.
The bike isn’t hefty, either, weighing approximately 60.8 lbs (27.6 kg). Therefore, one person can carry and assemble the bike. Also, once complete, relocation is via the front transport wheels.
Both base bars of the bike has a triangular shape for extra stability. The rear base comes with two adjustable stabilizers. Thus, you can quickly level it on any floor. The front base rests on two non-adjustable pads. Both back and front footpads are rubberized for extra floor protection.
Seat and handlebars
The Sunny SF-B2883 upright bike comes with a classic seat. Its top is slightly larger than the slim seats of some spin bikes. It is approximately 12.5″ (31.75 cm) long and 12″ (30.4 cm) wide, designed to provide an optimal contact surface. Also, its top has contours for extra comfort.
The bike’s seat offers 4-way adjustability (front, back, up, down). Its vertical post has several adjustment positions, and its horizontal slider allows a few inches of front-to-back adjustment. In addition, the vertical bar offers an adjustment span of approx. 9″ (22.8 cm), for users with an inseam between 26″ and 35″ (66 – 88.9 cm).
Thus, the bike comfortably accommodates users up to 6’3 ″ (190 cm) with no problem, allowing a complete leg extension. In addition, the bike has a maximum user weight capacity of 240 lbs (109 kg), which also applies to the seat.
This Sunny upright bike comes equipped with a multi-grip handlebar featuring two extended lateral grips curved at the top to provide close grip possibilities. Unfortunately, the bike’s handlebar is non-adjustable. It attaches to the front upright bar via two bolts, so you cannot adjust its angle. Also, the front vertical bar’s height is fixed and not adjustable.
A rubber foam material fully covers the handlebar to provide a secure grip. The side grips integrate metallic HR pulse sensors, so the bike’s fitness monitor can monitor your heart rate if you hold on to them.
SF-B2883 Drive System
The Sunny SF-B2883 upright bike integrates a 6.6 lbs (3 kg) flywheel. It’s not as heavy as the flywheels of most indoor cycling bikes, so when a low-level tension setting is selected, the cycle offers light resistance. However, the flywheel is perimeter-weighted, so it provides a bit of extra inertia.
The bike’s flywheel is bi-directional. Therefore, you can pedal in reverse if you want. However, coasting is not possible on it.
The bike features a durable crankset and a sizeable internal pulley. However, since it is an upright bike, it is intended only for seated workouts. Standing on the pedals is not advisable, as it may damage the internal components or the pedals, or you may injure yourself.
The included pedals are made of ABS material with a metallic center. They have weight elements that enable them always to turn face-up if you remove your feet from them. They are also equipped with adjustable straps to stabilize your feet on them correctly.
Last but not least, this Sunny exercise bike features a belt transmission system. Therefore, you don’t have to worry about its lubrication. It also delivers a very smooth and quiet pedaling motion.
The Sunny SF-B2883 upright bike has a motorized magnetic resistance system, which means the bike needs a power connection. Furthermore, the resistance is only adjustable from the bike’s fitness monitor. In addition, depending on the program, the monitor can auto-adjust the resistance.
The bike’s main resistance elements are a magnetic brake and a servo motor. For example, when you adjust the resistance, or the console automatically adjusts the resistance, the servo motor adjusts the brake’s position to the flywheel. Therefore, it leads to more or less magnetic tension and ultimately increases or decreases pedaling difficulty.
The bike offers 16 levels of resistance. The first few levels deliver a relatively light pedaling difficulty; they’re great for anyone who requires recovery training or has joint problems. Conversely, the top resistance levels provide more pedal tension simulating a hill climb, promoting a higher burn and superior cardio training.
SF-B2883 Fitness monitor
The bike features a mid-range fitness monitor featuring an LCD with an LED backlight. It tracks all the important workout metrics, including time, distance, total distance, speed, RPM, watts, calories, and pulse.
In particular, the pulse reading function requires holding the HR sensors integrated into the handlebars. Unfortunately, the monitor is not telemetric and cannot read your pulse through a wireless transmitter. In addition, speed and distance are shown only in Imperial units (MPH and miles); there is no metric option.
Unfortunately, the bike’s fitness monitor does not have Bluetooth connectivity and is incompatible with online fitness apps. However, it has 24 workout programs to keep you motivated. The list includes one manual program, 12 preset programs, a 1-watt program, 1 BMI program, 5 HRC programs, and four custom programs.
Plus, a Recovery function monitors how long your pulse takes to return to normal parameters at the end of the workout. It will give you a fitness rating between F1 (excellent) and F6 (poor).
The monitor also allows you to target time, distance, and calories. When a goal for these metrics is selected, the display will show the remaining value until it reaches zero.
Finally, the monitor does not have an integrated sound system or a workout fan but does integrate a tablet holder. In addition, its top section features a grid with the heart rate zones that you should aim for depending on your age to benefit from a better aerobic output, fat burn, etc.
SF-B2883 Assembly and Maintenance
The main body of this Sunny exercise bike comes pre-assembled. You only have to add the two base bars, the monitor mast, the fitness monitor, the seat post, the saddle, and the pedals.
Consequently, it shouldn’t take more than one hour of your time. In addition, all the necessary tools for assembly come with the bike. Also, the manual provides precise assembly instructions.
The bike’s maintenance doesn’t require much. You’ll need to remove the dust if it’s the case, keep liquids away from the console, check for loose bolts and parts before each workout, and retighten as needed.
