The Sunny Health and Fitness SF-B1805 Indoor Cycling Bike Overview

So, we recently reviewed the Sunny Fitness B-1709 Fitness Bike. It’s a cool-looking bike. Also, we appreciated its overall design and build.

However, today we are reviewing the Sunny Fitness SF-B1805 Cycling Bike. Keep in mind that both of them were released in 2018. Therefore, we expect them to be somewhat similar. They even share the price range. Nonetheless, the SF-B1805 is slightly more expensive.

As expected of Sunny Health and Fitness, this cycling bike offers magnetic resistance. Therefore, its operation is smooth and quiet. In addition to that, it also comes with an adjustable seat and handlebars.

Is it a good deal? Is this bike better than its cousin, the Sunny Fitness B-1709 Cycling Bike?

1. The steel frame and 44lbs flywheel

We hate wobbly bikes—They are so annoyingly distracting.

As expected of Sunny Health and Fitness, they have once again delivered a good quality fitness bike. Indeed, we appreciate its sturdiness.

We are happy to inform you that both the frame and stabilizers are heavy-duty steel. Therefore, we confidently recommend this bike to hardcore users—You can go all out with your intensive workout sessions.

Moreover, the SF-B1805 has a decent weight capacity of 300 lbs. All in all, it’s not the most impressive. However, it’s a good bargain if you consider all the other high-end features that come with it.

Next, we have the chrome 44lb flywheel. In case you didn’t know, the flywheel is the circular disk that appears to be connected to the pedals. Its function is to provide resistance.

At 44 lbs, we can confirm that the fly is heavy—The heavier the flywheel, the better the fitness bike. Not only do heavier flywheels offer good resistance for high-intensity workouts, but they also contribute to a smooth cycling experience.

Nonetheless, this Sunny Fitness bike isn’t perfect. We didn’t like its exposed flywheel.

Sure, some prefer the design. Not us. An exposed flywheel is more vulnerable to sweat and moisture than will cause corrosion.

We advise you to continuously wipe the flywheel after an intense and sweaty workout session.

“Does the Sunny Fitness bike come with magnetic-adjustable resistance?

Fortunately, it does. There is a knob that offers a range of resistance to intensify your workout sessions. However, there is one big problem. You can’t tell what resistance you are using. Indeed, there is no scale or console to give you a reading. Therefore, it’s difficult to replicate a previous setting.

2. The adjustable seat

“Is the seat comfortable?”

Yes, it is.

Sure, it’s not perfect. Nonetheless, Sunny Fitness did its best with this one. Its dimensions are 10″ L by 8″ by 3″ H. On top of that, it’s also padded for extra comfort.

Of course, seat comfort is a personal affair. However, we testify that there are worse seats than this one. If it isn’t comfortable, you can swap it up with your preferred one.

Yes, the seat is adjustable. It is perfect for people in the 5′ 2″ and 6′ 2″ height range.

Before buying a gym bike, always measure your inseam. It’s the length from the top of your thigh to the bottom of your foot. The Sunny Fitness B1805 is best suited for users with an inseam of 28″ to 38″.

3. Handlebars

Indeed, its handlebars are adjustable. Also, they have a thickness of 2”. That’s comfortable for most people.

Additionally, the handlebars are sweat-resistant and anti-slip. A good handlebar can go a long way in ensuring your workout sessions are fun and safe.

Closing Thoughts

As expected, the Sunny B1805 is capable. It’s a budget gym bike with all the necessary features for beginner, intermediate, and hardcore workouts.

Is it better than the SF-1709 gym bike?

In our opinion, yes. Its frame feels more sturdy and durable. Also, its flywheel mechanism puts a smile on our faces.
