SF-B020026 Frame Construction
The Sunny SF-B020026 mini exercise bike features a steel frame, but most of its median area has two large guards made from a durable thermoplastic material. The guard casing also features a handle at the top for easy portability.
The bike’s metallic frame comes double-coated with a corrosion-resistant gray paint finish. In addition, the end caps of the base bars are ABS material. Furthermore, they rest on rubberized pads. However, these are non-adjustable.
Since it’s an under-desk bike, the Sunny SF-B020026 doesn’t have a large footprint. However, with all the parts assembled, it is approx—21.6″ (55 cm) long and 18.7″ (47 cm) wide. The maximum pedal height is approx—12″ (30 cm).
However, you shouldn’t need that much clearance between your knees and the top board of the desk. Furthermore, you can place the bike farther from the seat, and your knees won’t raise that much.
The bike is also pretty light, weighing approximately 20.5 lbs (9.2 kg). Therefore, one person can carry and assemble the bike.
In addition, it’s also important to note that this Sunny exercise bike does not come with elastic bands for arm exercise like some other bikes or ellipticals. However, you can set the mini bike on a table and pedal with your hands to achieve an upper body workout.
The Sunny SF-B020026 exercise bike comes equipped with a manual magnetic resistance system. Therefore, it does not have an internal motor, and you don’t need to connect it to a power source. Unfortunately, on the other hand, the bike cannot adjust the resistance automatically and does not have pre-set programs.
The resistance system consists of a small magnetic brake placed near the internal flywheel and connected to the bike’s tension knob.
Thus, when you turn the knob clockwise, the magnets move closer to the flywheel, increasing the pedaling difficulty. Conversely, if you turn the knob to the left, the gap between the magnets and the flywheel increases, and the pedaling difficulty is reduced.
The bike offers eight levels of resistance. The lowest level delivers a relatively light pedaling difficulty, great for recovery training, muscle toning, or warming up. Conversely, the 8th level of resistance provides considerably more pedal tension, which is excellent for strength and stamina development.
The bike’s magnetic resistance system comes with two main advantages. First, the magnets do not touch the flywheel, so there is no internal friction, and you won’t ever need to lubricate or replace the brake. And second, the pedaling motion is very smooth and quiet.
SF-B020026 Drive system
Since the Sunny SF-B020026 is a mini exercise bike, it does not have an extra-heavy flywheel. Instead, it comes equipped with a 3.5 lbs (1.5 kg) flywheel concealed by the large frame covers. The flywheel has a perimeter-weighted design. Moreover, this leads to a more stable and smooth pedaling motion and more consistent momentum.
The flywheel is bi-directional, meaning you can pedal forward or backward. However, coasting is not possible on this bike, and when pedaling in reverse, the resistance remains constant, given the selected level.
Like most exercise bikes with a magnetic resistance system, the Sunny SF-B020026 has a belt drive system. It uses a J300 poly-v belt highly resistant to stretching and abrasion.
The main advantage of the belt drive is that you don’t have to take the covers apart to lubricate the transmission periodically, and the belt generates slightly less vibration than a chain.
The bike comes equipped with a pretty sturdy crankset. Its arms are shorter than the arms of a regular road bike, so the Sunny SF-B020026 offers a stride of approx. 7″ (18 cm). In addition, the Q-Factor (spacing between the pedals) is pretty narrow, so you won’t experience any lateral stress on the knees.
No maximum user weight limit is specified for this exercise bike as it’s mainly for seated exercises. The included pedals are heavy-duty nylon material with internal metallic rods. They are narrow, so you can get a comfortable grip if you want to use this bike for arm exercises. In addition, they also have adjustable straps.
The Sunny SF-B020026 mini exercise bike has a pretty simple fitness monitor. It has an LCD that tracks time, distance, speed, and calories burned. Unfortunately, the speed and distance are in MPH and miles; there is no option for changing the units to metric. Furthermore, the monitor does not indicate RPM and also does not have a pulse reading function.
In addition, there are no pre-set programs on the monitor either, but it does have a goal-setting function. Therefore, it allows selecting a workout target for time, distance, or calories.
After choosing a goal, the monitor will count down from the specified value until it reaches zero. Indeed, this is a plus, as it can help you keep track of your progress from one workout session to another.
The fitness monitor is straightforward to use. It has three buttons, which are Set, Mode, and Reset. The Set button covers the goal-setting function.
The Mode button allows you to select the workout metric you want on display or the Scan Mode. In Scan Mode, the monitor rotates the four workout metrics, showing each one for four seconds. The Reset button clears all the values to zero.
The fitness monitor is battery-powered, and it requires 1 AAA battery which comes included. It starts up automatically when it detects flywheel movement or when you press the Mode button. In addition, it automatically turns off after a few minutes of inactivity on the bike.
SF-B020026 Assembly and Maintenance
The main body of the bike, with all the drive and resistance elements, comes pre-assembled. You only need to attach the two base bars and the pedals. Consequently, this shouldn’t take more than 15 minutes of your time. All the necessary tools come with the machine, and the manual provides clear step-by-step assembly instructions and schematics.
Once assembled, maintenance doesn’t require much. You only have to keep it clean, periodically check for loose parts, and retighten them as required. The pedals might need lubrication after a while. However, the internal components should not need any lubrication or other maintenance.
