The Sunny Pro II SF-B1995 is one of the indoor cycling bikes released by Sunny Health & Fitness in 2020. It’s basically an upgraded version of the Sunny SF-B901. It has a similar construction, the same type of resistance, and the same weight capacity. However, it features a belt drive system, it has a pulse reading function and an exercise meter that tracks all the important workout metrics.

Frame construction
The Sunny Health & Fitness Pro II SF-B1995 features a standard triangular frame made of durable 
rectangular steel tubing. The fully assembled bike is quite heavy; its net weight is 101 lbs (46 kg) which is more than twice the weight of the average mountain bike. All this weight delivers superior stability. Plus, both base bars of the bike are equipped with adjustable stabilizers.
Despite its weight, the bike is fairly easy to move once it is assembled. Its front base bar is equipped with two large silicone wheels which facilitate its relocation.
The bike cannot fold in any way but does not have a very large footprint. With all the parts assembled, it is only 49.5″ (126 cm) long, and 20″ (51 cm) wide. It is recommended, though, to leave at least two feet of clearance all around it for ease of access and safe usage.
Although all the frame parts are made of steel, the bike does integrate several ABS plastic parts as well. The belt cover, the flywheel lateral covers, and several other small covers are plastic-made. Also, all the steel parts in the bike’s construction are coated with a corrosion-resistant paint finish. The colors used are gray for the main frame, and black for the seat and handlebar posts. The flywheel, on the other hand, is chrome-plated.
One last aspect to mention here regards the small horizontal bar that connects the seat tube with the main oblique tube. This bar can be used as a step-up element. It can also serve as support for stretches and other exercises. Not all bikes have this feature, so it’s quite a plus.
Seat and handlebars
The Sunny Health & Fitness Pro II SF-B1995 indoor cycle is equipped with a four-way adjustable 
seat (up, down, front, back). Its upright post has several adjustment positions while its horizontal slider offers a few extra inches of fore/aft adjustment. Therefore, the bike should accommodate users between 5’0″ and 6’5″ (153 – 196 cm) allowing a complete leg extension.
The included saddle is a pretty standard one. It is a bit larger than the average race seat. It’s 10.5″ (26.7 cm) long, and 7.75″ (19.6 cm) wide. Its top combines polyurethane and vinyl element. It integrates a thin layer of padding for extra comfort. It also has a longitudinal groove for improved breathability.
It’s also important to mention that the seat’s attachment system is collar-type and attaches to the slider by a bolt and nut. This type of attachment system is pretty standard, so if you will ever need to replace the seat, compatible options are widely available.
The Sunny SF-B1995 indoor cycling bike features a multi-grip handlebar. It offers the possibility to adopt a standard grip, a race grip, a climbing grip, and an aero grip. Its aero bars are pretty long, so you can comfortably rest your elbows to reduce the impact on your wrists. Also, the side grips integrate pulse sensors and the included exercise meter has a pulse reading function.
As opposed to the seat, the bike’s handlebar is only two-way adjustable (up, down). It does not have the horizontal slider.
Drive and resistance
As we’ve mentioned above, the Sunny Health & Fitness Pro II SF-B1995 exercise bike is equipped with a
belt drive system. This type of drivetrain comes with several advantages. First of all, it generates less vibration than a chain and contributes to the overall smoothness of the ride. The pedaling motion is very quiet. And finally, it doesn’t require lubrication like a chain.
The bike is equipped with a heavy, 40-lb (18 kg) flywheel. It is chrome-plated and has red ABS side panels for improved aesthetics. It has a perimeter-weighted structure for improved inertia which is pretty important for spinning.
The flywheel is bi-directional. In other words, it allows reverse pedaling. However, as it is the case for most exercise bikes, coasting is not possible. The pedals continue to spin for as long as the flywheel is spinning.
The Sunny SF-B1995 features a dual-pad friction resistance system. In other words, its brake has a similar construction to a standard bike brake, only the contact area of the pads has a layer of felt material, not rubber. The brake is attached to the turn-knob on top of the bike frame. By turning this knob clockwise, the brake tightens onto the flywheel which increases the pedaling difficulty.
The bike’s resistance system is stepless. This means there aren’t any tension levels marked on the adjustment knob. You simply tighten it until you get the desired pedaling difficulty. The brake also features a press-down lever. By pressing this down, you can instantly stop the flywheel from spinning, which is pretty necessary if you’ve been pedaling at a very high speed.
Last but not least, the bike is equipped with a heavy-duty crankset. It is rated for a maximum user weight capacity of 275 lbs (125 kg) which also applies to the pedals. In other words, if you don’t exceed this weight, you should be able to pedal while standing up with no problem.
The pedals are made of aluminum alloy. They integrate non-slip elements and feature adjustable toe cages. They don’t have SPD elements for spin shoes but their threads are standard (9/16) so you can always replace them.
Performance monitor
This Sunny Health & Fitness exercise bike is equipped with a basic fitness monitor. It does not have
pre-set workout programs, online connectivity, or goal settings. It features an LCD display (without backlight) that indicates time, distance, total distance (odometer), speed, RPM, calories, and pulse. Speed and distance are shown in English units only (MPH and miles). As for the pulse reading, the unit is not telemetric. This means it can only read your pulse if you hold on to the integrated sensors. It cannot communicate with a wireless HR chest strap.
The performance monitor unit features only one button (MODE). By pressing this button repeatedly, you can scroll through the workout metrics and select the one you want to view. This way, you can also select the Scan Mode which automatically rotates all the metrics, showing each one for 6 seconds. The button also has a reset function. You can press and hold it for a few seconds to clear all the values to zero, except the odometer. The odometer can only be reset if you remove the batteries.
The monitor unit requires two AAA batteries which are included. It starts up when you press the Mode button, or when you begin pedaling. It also automatically turns off if it doesn’t detect flywheel movement for more than four minutes.
Assembly and Maintenance
The bike’s frame with the flywheel, brake, belt, and crankset, comes pre-assembled. You only need to attach the two base bars, the seat post, the saddle, the handlebar post, the handlebar, the performance monitor, the pedals, and several small covers. This shouldn’t take longer than 30 minutes. The manual provides clear assembly instructions and diagrams, and all the necessary tools for the task are included.
For maintenance, the lubrication of the brake pads may be required. A few drops of silicone lubricant applied on each side of the flywheel’s edge should cover it. Other than this, you only have to keep the bike clean and periodically check for loose parts.
