The Sunny SF-B1110 Indoor Cycling Bike offers a number of important improvements over the earlier SF-B1001 model, including 14 lb of additional flywheel weight, and an enhanced handlebar adjustment system.
In our review, we take a closer look at the design features, workout options, customer reviews, and even quality of the user manual. This is to help you decide whether the SF-B1110 is the best spin bike for your personal fitness goals and budget.
If you’re looking for an indoor exercise bike that can provide challenging levels of resistance for high intensity cycling workouts, your best option is usually to look for a high quality studio/spinning style bike.
This is exactly the type of workout that the Sunny SF-B1110 has been designed for, which also includes a range of adjustment options for the seat and handlebars to ensure you can find a comfortable cycling posture.
If you’re buying an indoor bike to compliment your outdoor road cycling, this allows you to create a setup that closely matches your road bike, leading to more transferable time and fitness gains.
The seat and handlebars each adjust using a similar system; hand wheel for the height, lever lock system for the horizontal adjustment.
While there are some studio bikes that use a pull-pin style of height adjustment, unless there is more than one person using the bike then it shouldn’t be too much more hassle to use the hand wheel system.
As well as creating a cycling position that’s both comfortable and efficient, it’s also important to position the bike on stable ground to help reduce the risk of unwanted movement in the frame.
The Sunny SF-B1110 makes this easier by having a set of 4 base levellers, one attached to each corner.
These can be used to compensate for any smaller deviations in the floor that you place the bike on, which can be particularly useful if you are short on space and placement positions are limited.
If you do need to move the bike between workout and storage areas, having the set of transport wheels attached to the front base stabilizer certainly makes it easier.

Flywheel and resistance system design
Generally speaking, you tend to find that studio style exercise bikes with a heavier flywheel offer a smoother cycling motion, with a cadence that matches outdoor road bike cycling closer than bikes with a smaller flywheel.
At 44 lb in weight, the flywheel for the Sunny SF-B1110 is one of the largest available, helping to produce a smoother cycling motion and increase the stability of the bike during your workout.
The resistance is generated via a friction pad that rubs against this flywheel as it rotates. Moving the friction pad closer to the flywheel results in a more challenging workout, while moving it further away will start to reduce the resistance.
This is all controlled manually, using a dial positioned just above the friction pad, and within easy reach of your seated position.
In the case of any emergencies, this tension control knob can be pushed straight down to act as an emergency brake, stopping transmission completely.
Combining ergonomics and comfort
A quick look at the customer reviews section of many online marketplaces will show you that studio bikes have a pretty tough time when it comes to saddle comfort.
Although gel seat covers are available separately, which improve the level of comfort over the course of longer workouts, the stock saddle that comes with the bike is usually described as being quite hard to sit on.
The saddle for the Sunny SF-B1110 isn’t made of plastic – so it’s more comfortable than some designs, and it has been ergonomically shaped to allow unrestricted movement in your legs while still providing the support you need.
Handles are another area that needs to be both ergonomically designed and comfortable to grip.
In the case of the SF-B1110, the soft coating around the length of the bars provides a comfortable surface to hold onto, regardless of your preferred grip position.
There are also several of these grip positions to choose from, catering for everything from a gentle cycle to a more intense time trial.
Ease of assembly
Unless you are moving house or want to move the bike between floors in lighter pieces, the chances are that the assembly process is something you will only need to do once.
In our experience of reviewing the instruction quality for some of the other entry level studio exercise bikes, the steps are usually a little difficult to follow.
Fortunately that doesn’t seem to be the case with the SF-B1110, and you shouldn’t be put off by the extensive parts list that references every part that went into the design of this bike.
The beauty of studio style bikes is that the majority of the assembly is often done for you at the factory, with the flywheel and main bike frame arriving already pre-assembled.
From there, it takes just 5 steps to talk through the remaining setup, resulting in a recommended assembly time of less than 30 minutes.
If you’re interested in having a read through the user manual for yourself before buying, or have simply misplaced your own copy, feel free to have a read of ours.
All the tools you need are also provided.
If you’re more used to using an upright or recumbent style of exercise bike, then you may have used one of the built-in preset workout programs that these designs usually offer.
Unfortunately studio style bikes don’t often have display consoles, and the ones that do will usually cost many multiples of what you can currently buy the Sunny SF-B1110 for.
So without a display console to provide workout feedback or selection of preset workout programs to choose from, what are your options in terms of workout plans?
One option is to invest in additional fitness tracking equipment. This can be something as simple as a heart rate chest belt and receiver watch, so that you can monitor your heart rate level and ensure you stay within a target range.
This can be used in conjunction with a clock or timer to switch between periods of low and high intensity training, as part of an interval workout.
Currently one of their most popular indoor exercise cycles, the Sunny Health and Fitness SF-B1110 bike manages to maintain an impressive average review rating on many online stores.
The low price that places it just above entry level will certainly be a factor in its popularity, but what about the other reasons? What is it about the design and quality of ride that reviewers like so much?
Reading through the full reviews will usually be the best way to answer these questions, but with so many to read through it can be a time consuming process.
That’s why to save you time, we’ve read through many of these reviews (both the good and the bad) to provide you with summary lists of the pros and cons.
We weren’t surprised to find that the distribution of ratings was heavily weighted towards the 4 and 5 star levels, with very few ratings below 3 stars.
