Frame And Flywheel


The SF-B1714 Sunny Health & Fitness Pro indoor spin bike features a heavy-duty steel frame. It’s coated for anti-corrosion and supports up to 330 lbs weight capacity. The steel tubes used for the construction of this sunny health & fitness Bike is thicker and sturdier compared to any other spin bike in this price category.

Therefore, the bike remains sturdy and firm during intense cycling workout. The frame also features 4 large foot levelers. They are also adjustable so, that you can have a stable spinning session on uneven floors. There are transport wheels for easy portability and a water bottle holder to stay hydrated.

Magnetic Pro Sunny Health and Fitness indoor cycling bike has a 44-lb flywheel designed to create a real and natural indoor cycling momentum. Because the flywheel is heavy and Chromed, you won’t feel the up&down or jerky pedaling motion with Evolution Pro spin bike.

Drive Mechanism


Evolution Pro Sunny Health and Fitness cycling bike has a top-notch drive system. With a single durable belt, the SF-B1714 Sunny Health Fitness bike provides an enjoyable quiet spinning workout at home. Not only it’s very quiet, but the Evolution Pro magnetic spin bike requires very little maintenance.

Unlike the chain-drive mechanism, you wouldn’t need to lubricate the belt. The other great feature of Evolution Pro Sunny Health and Fitness belt drive indoor cycling bike is the resistance system. The Evolution-Pro features magnetic resistance which is silent and also maintenance-free.

Unlike brake pads, the magnets don’t touch the flywheel. Therefore, they don’t wear out and don’t make any noise. The resistance on Evolution Sunny Health and Fitness pro bike is adjustable through a knob which also functions as an emergency brake. The magnets are large enough to create a challenging cycling workout for the elite as well as beginners.

Pedals and Q-Factor


Evolution Pro Magnetic Sunny Health and Fitness belt drive spin bike features a relatively wide Q-factor size. With 216mm the Evolution Pro exercise bike has one of the widest q-factors on the market. Q-factor is the gap between the two pedals. If the gap is too wide, your ankles and knees can’t stay aligned with your hips.

Therefore, it adds stress to your lower-body joints. So, the q-factor is an important feature in an indoor exercise bike. As far as the pedals go, the Evolution Pro Sunny Health spin bike pedals are one-sided. That means you can exercise on this spinning bike with normal athletic shoes but you can’t workout with SPD mountain cycling shoes.

If you are serious about doing a proper weight-loss workout, we recommend you get a pair of Shimano pedals. They are dual-sided so, you choose to workout with spd cycling shoes or normal shoes. Note: The Sunny Health and Fitness Evolution Pro magnetic belt drive exercise bike pedals have adjustable straps and non-slip surface.

Handlebars and Seat


Evolution Pro SF-B1714 Sunny Health and Fitness Indoor bike feature fully adjustable handlebars and seat (up&down fore/aft). So, the majority of user heights can find a natural spinning position. And that’s another reason this Sunny spin bike is one of the best exercise bikes for home.

Your daughter/son and partner can adjust the bike to their height so, they would cycle without pain and hurting their backs. The handlebars are sweat-resistant and offer multiple cycling grips.

Evolution Pro Sunny Health Fitness spin bike comes with a comfortable padded seat. The seat and handlebars posts are both marked. So, it’s easy for you to get back to previous settings if someone else uses the bike. Note: The seat inseam adjustment is Min 30.1” and Max 38.3.

Bike Computer

Unlike the Sunny ASUNA sprinting 6100, the Evolution Pro indoor bike doesn’t have a console. Therefore, if you want to track your spinning exercise stats, you need to separately purchase a spin bike computer. One of the best spin bike computers is Spinning BIO HR Wireless Computer.

It’s a package that includes a Wireless chest strap, LCD display, speed and cadence sensors, and LCD holder. This computer is compatible with any spin bike and it’s also very easy to install. It allows you to track Cadence, Speed, Time, Distance, Calories, and Heart Rate.

You can find out more information on this spin bike computer on the link I provided above. Note that if you want to connect your spin bike to the online spinning racing Apps, you will need to buy a Wahoo sensor. It allows you to connect your bike online and track your stats on your devices (phone, tablet, TV, & computer). To find out more about the Wahoo sensor, see the spin bike computer link above.
