Sunny Pro II SF-B1995 Indoor Cycling Bike | Features a Belt Drive System

The Sunny Pro II, SF-B1995 Indoor Cycling Bike, is an upgraded version of Sunny Pro SF-B901. It has a similar construction, the same type of resistance, and the same weight capacity. However, it features a belt drive system, and it has a pulse reading function and fitness console that tracks all the essential workout metrics.

The SF-B1995 features a massive 40 lb perimeter-weighted flywheel that creates more momentum for smoother, quieter workouts. Sunny Health and Fitness’s Flywheel is second to none regarding stability, sturdiness, and quality. Continuing the original’s signature resistance system, the Pro II comes equipped with a quiet and smooth dual felt fabric brake pad system.

The Sunny Pro II SF-B1995 comes equipped with a fitness console that tracks all the essential metrics Speed, Distance, Time, Calories Burned, Odometer, RPM, Pulse, and Scan. However, the console is not telemetric, which means that it can only read your pulse if you hold on to the handlebars’ integrated sensors.

The SF-B1995 comes with a 4-way adjustable seat (up, down, front, back). Its upright post has several adjustment positions, so the bike should accommodate users between 5’0 ″ and 6’5 ″ (153 – 196 cm), allowing a complete leg extension. The Pro II features a multi-grip handlebar. It offers the possibility to adopt a standard grip, a racing grip, a climbing grip, and an aero grip.

SF-B1995 Frame construction

The Sunny 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 average mountain bike’s weight. All this weight delivers superior stability. Plus, both base bars of the bike come equipped with adjustable stabilizers.

Despite its weight, the bike is relatively easy to move once assembled. Its front base bar comes equipped with two large silicone wheels, which facilitate its relocation.

The bike cannot fold in any way but does not have an enormous footprint. With all the parts assembled, it is only 49.5″ (126 cm) long and 20″ (51 cm) wide. However, it is advisable to leave at least two feet of clearance all around it for ease of access and safe usage.

Although all the frame parts are 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 come coated with a corrosion-resistant paint finish. The colors used are gray for the mainframe 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 a step-up element. It can also serve as support for stretches and other exercises. Not all bikes have this feature, so it’s a plus.

Seat and handlebars

The Sunny Pro II SF-B1995 indoor cycling bike comes 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.

The seat’s attachment system is 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 compatible options are widely available if you ever need to replace the seat.

The SF-B1995 indoor cycling bike features a multi-grip handlebar. It offers the possibility to adopt a standard grip, a racing grip, a climbing grip, and an aero grip. Its aero bars are pretty long, so you can comfortably rest your elbows to reduce your wrists’ impact. The side grips integrate pulse sensors, and the included fitness console 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 a horizontal slider.

SF-B1995 Drive system

As I’ve mentioned earlier, the Sunny Pro II SF-B1995 indoor cycling bike comes 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 ride’s overall smoothness. The pedaling motion is tranquil. And finally, it doesn’t require lubrication like a chain.

The bike comes 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 essential for spinning.

The flywheel is bi-directional. In other words, it allows reverse pedaling. However, as is the case for most exercise bikes, coasting is not possible. The pedals continue to spin for as long as the flywheel is spinning.

Resistance system

The SF-B1995 has 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 infinite. This means there aren’t any tension levels marked on the adjustment knob. You tighten it until you get the desired pedaling difficulty. The brake also features a press-down lever. You can instantly stop the flywheel from spinning by pressing this down, which is pretty necessary if you’ve been pedaling at a very high speed.

Last but not least, the bike comes equipped with a heavy-duty crankset. It has 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 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.

SF-B1995 Console

This Sunny Pro II SF-B1995 indoor cycling bike comes equipped with a fitness console. It does not have pre-set workout programs, online connectivity, or goal settings. It features an LCD (without backlight) that indicates time, distance, total distance (odometer), speed, RPM, calories, and pulse.

Speed and distance are in English units only (MPH and miles). As for pulse reading, the console 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 console 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 set 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 reset if you remove the batteries.

The console requires two AAA batteries, which come included with the bike. 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.

SF-B1995 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 fitness console, 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 come included with the bike.

For maintenance, the brake pads may require lubrication. 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.
