1. although arrived safely, given past reviews of various Sunny bikes could have been packed a bit more securely;
2. heart rate monitor is wildly inaccurate;
3. display feels somewhat cheap—it is large and legible in good light, but hard to read if the lights are low or you are standing (i.e., while doing hill climbs);
4. seat and handlebars should be more adjustable;
5. tablet/phone/book holder is a decent nice size, but the “lip” holding your tablet, phone, or book is too small in depth; and,
6. water bottle and dumbbell holders are not conveniently located.

Sunny Health and Fitness Evolution Pro II review


The fully assembled bike is quite heavy, similar to a commercial bike. Its net weight is approx. 136 lbs (61.6 kg).  Plus, it has a low center of gravity and due to its impressive weight, it provides superior stability. You can be sure that it won’t rock or move even if you engage in a high-intensity spin workout. The Sunny Evolution Pro II SF-B1986 is not an extremely large fitness machine, but it is a bit larger than most spin bikes made for home use. It is approx. 49″ (124 cm) long, and 24″ (61 cm) wide.

Frame construction

Sunny Health and Fitness Evolution Pro II review
Sunny Health and Fitness Evolution Pro II review

The main section of the frame is double-coated with a corrosion-resistant and chip-resistant paint finish, with the exception of the seat and handlebar posts; these are chrome plated. The Sunny Health & Fitness Evolution Pro II features a heavy-duty steel frame designed to support any spin workout. It combines oval and rectangular bars in its construction for improved sturdiness and aesthetics.


To begin with, its display is divided into four sub-sections so you can view up to four workout metrics simultaneously. It shows speed, average speed, maximum speed, cadence (RPM), average cadence, maximum cadence, distance, calories, time, and pulse.

Speed and distance are by default set to English units (mph and miles), but the monitor unit offers the possibility to set them to metric units. The pulse reading function is grip contact only. The monitor unit cannot communicate with a wireless heart rate chest strap, so in order for it to read your pulse, you have to hold on to the sensors integrated into the handlebars.


The flywheel is bi-directional; it allows pedaling in reverse. However, coasting is not possible on this bike. That’s because the pedals continue to spin for as long as the flywheel is spinning. The bike is equipped with a 40 lbs (18.1 kg) flywheel which has a perimeter-weighted design. This type of flywheel construction is meant to improve inertia and leads to a very smooth and consistent pedaling motion.

Seat and handlebars

The bike is equipped with a multi-grip handlebar. It offers the possibility to adopt a climbing grip, an aero grip, a close grip, a standard grip, and a racing grip. It is fully covered by a layer of high-density foam material for an improved grip. Its side grips integrate metallic pulse sensors and the included fitness monitor has a pulse reading function. This feature is not available with the Evolution Pro I model. Also, the handlebar incorporates a tablet holder.

The bike comes with a saddle similar to the one included with the Evolution Pro II. It’s a bike seat designed for superior comfort. It is approx. 10.5″ (26.6) long, and 7.75″ (19.6 cm) wide so it provides plenty of contact surface. It integrates a thick layer of foam padding and has a longitudinal groove for improved breathability.

Pedals and other feature

The bike is equipped with a belt drive system. It uses a 5PK1590 poly-v belt resistant to stretching and abrasion. The main advantage of this belt drive is that you don’t have to ever lubricate it. Also, it delivers a vibration-free pedaling motion which contributes to the overall smoothness of the ride.

The included pedals are dual-sided. They have adjustable toe cages on one side and SPD elements for spin shoes on the other. They also have 9/16 standard threads, so in case you will ever need to replace them, compatible options are widely available.


The bike’s handlebar is four-way adjustable (up, down, front, back). Its upright post offers 5 adjustment positions while its front-to-back slider offers approx. 2 extra inches of horizontal adjustment.

The seat is four-way adjustable (front, back, up, down). Its upright post has 9 adjustment positions and offers an adjustment span of approx. 10″ (25.4 cm). Its horizontal slider also offers approx. 3″ (7.6 cm) of front-to-back adjustment.

Therefore, the applicable inseam length for this bike is 29″ – 39″ (73.6 – 99 cm). Differently put, the bike should be able to accommodate users between 5’1″ and 6’6″ (155 – 198 cm). It is also rated for a maximum user weight limit of 330 lbs (150 kg).

Drive resistance

The bike’s resistance system consists of a magnetic brake attached to the main inclined bar of the frame above the flywheel. The brake is connected to the tension knob on top of the frame. Therefore, by turning the knob clockwise, the magnets move closer to the flywheel which increases the pedaling difficulty. The main advantage of a magnetic brake is that the resistance elements do not touch, so there is no friction and the pedaling motion is very smooth and quiet.

Dumbbell and Water Bottle Holders:

  • Dumbbell holders hold up to 15 pounds each for added weight training integration into your spin routine.
  • Water bottle holder guarantees easy access to drinks on the fly.
  • Tablet holder to allow you watch your favorito show while burins calories.

Assembly and Maintenance

The bike’s frame comes pre-assembled. The flywheel, the brake, the crankset, and the belt are already installed. You only need to attach the two base stabilizers, the pedals, the seat tube, the saddle, the handlebar tube, the handlebar, the performance monitor, the dumbbell holder, and the bottle holder. The task is pretty simple and shouldn’t take more than 30 minutes. All the tools for the assembly are included and the manual provides very clear assembly instructions.

For maintenance, you only have to keep the bike clean, wipe off the sweat from the frame at the end of the workout, and periodically check for loose bolts and parts. The belt and brake do not require lubrication.

Alternative of Sunny Health and Fitness Evolution Pro II

This is where I compared the Evolution II indoor cycling bike with similarly priced indoor bikes on the market and let you know if there is a better option for this price tag. Currently, in 2020, the II SF-B1986 offers a great deal value for its price ($750).

Thanks to the combination of heavy flywheel, belt transmission, and magnetic resistance, you will get a pretty silent and smooth ride. Unlike the older model (Evolution Pro) the “Evolution Pro II” has SPD pedals, an RPM reading monitor with a built-in cycling game/program, and a nice tablet holder making it a great value for indoor cycling.

However, if you can’t afford this model and don’t mind the lack of SPD pedals and tablet holder, you may want to check out the HMC indoor bike. It is cheaper, has RPM reading, magnetic resistance, a 44-lb flywheel, and offers a great deal of durability and value. Note: If by the time you read this Evolution Pro II SF-B1986 review, the price of this cycle is the same as the Schwinn IC4, I suggest you buy the IC4. It has Bluetooth and a better warranty.
