Sunny Health and Fitness Upright Bikes Reviews and Comparisons

Upright exercise bikes are the type of at-home exercise equipment that you typically picture. It’s the type of bike that you’d find at the local gym, but now it sits in your basement (or some other spot in the home. Sunny Health & Fitness (SH&F) have made quite the career off of making and selling these exercise bikes for relatively modest sums. However, they don’t always quite hit the mark in terms of quality. We’re here to check out another lineup of the Sunny Health & Fitness upright bikes and see which ones come out on top.

The stationary bikes that we have selected today don’t really have any special names, but you can find them from their specification numbers. The Sunny Health & Fitness bikes that we have selected are the SF-B2969, SF-B2883, SF-B2952, the ASUNA 4200 and the SF-B2906.

The first elements that we are going to look at for this collection of SH&F bikes are their technical specifications. These are their size, weight, material and just general characteristics that make up their backbones (literally). All of these upright bikes have a standard steel frame and can generally hold users between 5’1” and 6’3/5”.

We’ll start with the largest of this collection: the SF-B2969 cardio bike. While it might not take up that much larger of a footprint than the rest of the bikes, it is still the biggest. It measures out to be 48 inches (122 cm) long, 21.5 inches (54.6 cm) wide and 56 inches (142.2 cm) tall. It weighs about 68 lbs (30.8 kg).This also means that it can hold the most weight at 300 lbs (136 kg).

The SF-B2883 upright bike is much smaller in length, but still weighs a decent amount. It weighs 60.9 lbs (27.6 kg) and can hold 240 lbs (108.6 kg). It’s footprint measures out to be 34 in (86.4 cm) long, 22.5 in (57 cm) wide and 55.5 in (141 cm) tall.

The SF-B2952 indoor bike measures out to be 40.5 in (103 cm) long, 21 in (53 cm) wide and 51 in (129.5 cm) tall. It weighs less than the previous two exercise bikes at 56 lbs (25 kg), although it can hold a maximum weight of 275 lbs (124.7 kg).

The ASUNA 4200 upright bike measures out to be 41 in (104 cm) long, 21.5 in (54.6 cm) wide and 56.75 in (144 cm) tall. It weighs 99 lb (44.9 kg) and can hold a maximum weight of 265 lbs (120 kg).

Finally, the SF-B2906 exercise bike weighs 44 lbs (20 kg) and can hold the same amount as the SF-B2883: 240 lbs (108.6 kg). Its footprint measures out to be 35 in (89 cm) long, 20.5 in (52 cm) wide and 51.5 in (130.8 cm) tall.

The resistance of these bikes are generally similar, although there are a few key differences between them. They do all take the magnetic form and have belt drives in order to keep the workout silent and require low maintenance. We don’t know the exact Q-Factor of these bikes, which is unfortunate. We do know that the ASUNA 4200 has a slightly narrower Q-Factor than normal, which is not ideal. For those who are unaware, the Q-Factor is the distance between the pedals. If it is too wide, you get uncomfortable. If it is too narrow, the same happens and you can even get injured.

We have more information on both the SF-B2969 and SF-B2883 exercise bikes, as they are the “premium” bikes of this line-up along with the ASUNA 4200. However, the ASUNA 4200 does not share all the same boons. We know that both crank types are 3-piece, which is superior to the 1-piece cranks of the other three bikes. Both pedals are also self-levelling with adjustable straps to keep your feet firmly in place while cycling. Then we have the flywheel weights. The SF-B2969 has a flywheel that weighs 7.7 lbs (3.5 kg), while the SF-B2883 has a flywheel that weighs 6.6 lbs (3 kg).

Then there are the SF-B2952, the ASUNA 4200 and SF-B2906. All have a 1-piece crank, which means that it is more prone to breaking all at once (if it does indeed break). We don’t have any information on the flywheel weights, which is another negative. All the sets of pedals are fairly simple, with the SF-B2952 and ASUNA 4200 indoor bikes having weighted pedals with straps that turn up when you take your feet off. The SF-B2906 has extremely basic plastic non-slip pedals with adjustable straps that don’t do anything special at all.

ASUNA 4200ASUNA-4200-Upright-bike-ReviewNoFixed handlebarsVertically and Horizontally AdjustableNo resistance controls on the handlebars

The handlebars and seating of each of these bikes are fairly straightforward, with the only real exception coming in the form of the SF-B2906 cardio bike. It has a seat that is only vertically adjustable, although it can change about as much as the rest of them.

All of the other Sunny Health & Fitness home exercise bikes have handlebars that cannot be adjusted, but are multi-grip. This gives the user options as to where they want to place their hands. Each handlebar also comes with a pulse reader in order to roughly track the heart rate. An issue with most of the seats is that they aren’t fantastically comfortable with the exception of the SF-B2969. It is the most comfortable of the lot, although it still doesn’t hold up to some other non-SH&F seats out there. Meanwhile, the ASUNA 4200 has the most adjustable of the seats, as it is able to adjust between 28 inches and 40 inches.

The monitors of these Sunny Health & Fitness exercise bikes are actually fairly decent for the pricing. They are each a standard sized LCD monitor that has a variety of statistics that they track. Each of them consistently tracks statistics like your time, distance, speed, calories, pulse, RPM, and heart rate. You can scan through these statistics using the scan mode that each comes with. None of the monitors can display statistics in metric measurements unfortunately. However, there are still differences between these monitors.

The SF-B2969 monitor is by far the best of the lot. It has 12 preset workout programs and modes that it comes with, extending the amount of workouts that you can choose from on any given day. It also is the only monitor here to give Bluetooth connections and a USB port for contact with a mobile device. Unfortunately, the Bluetooth can only be used to play music through the speakers on the bike, rather than keeping any sort of workout data long term. But hey, you still get speakers!

The SF-B2883 cardio bike has the second best monitor. It has a whopping 24 modes available, including 12 preset workout programs that you can choose from. This lets you get in order to get all sorts of exercise. However, this seems in part to make up for the lack of any cool speakers or Bluetooth connectivity that the SF-B2969 has.

The ASUNA 4200 still has workout programs and can track the same stats as the SF-B2883. However, it doesn’t have as many and still remains a bit of a lesser piece of technology. It is still superior to the SF-B2952 and SF-B2906 though.

We finally arrive at the section which might make or break your decision. Sunny Health & Fitness are extremely consistent about warranties, which can look worse as the price goes up. Almost all of these warranties are identical, with 3 years on the frame and 180 days on the parts, belt and every other piece of the bikes. The only difference is the ASUNA 4200, which has 5 years on the frame. There are no labour warranties to be found. They aren’t bad per say, but they could be better.

The SF-B2969 upright bike, as the most premium choice here, naturally costs the most. It ranges between $472 and $555, which is not actually too expensive. Looking at some other upright magnetic bikes that cost thousands, these prices in general will look fairly low.

The ASUNA 4200 upright bike is cheaper, although it still is the second most expensive on this list. It typically falls between the prices of $400 and $470, which is about middle of the range when it comes to these bikes.

The SF-B2883 is the third most expensive bike here. It can generally range between $360 and $450 for a retail cost. Once again, this isn’t too bad, although we’ll save our final judgements for further down.

The SF-B2952 upright bike comes in fourth of the most expensive bikes here, although it costs a fair bit less than the SF-B2883. It costs between $290 and $320. This is starting to get into the range that makes the warranties look quite good.

Finally, there’s the SF-B2906 upright bike. The cheapest of the five bikes, it can range between $218 and $260. This is an OK price if you are looking for something cheaper without some of the bells and whistles that come with the pricier options. Once again, the warranties look better here than on the more expensive bike.

Now we’re going to look at some of the other elements that don’t fit nicely into any of the above categories. Each of these Sunny Health & Fitness home exercise bikes have transport wheels and stabilizers, although only the SF-B2906’s wheels stand out as useful. The rest are a bit too small to really be too helpful. They still work, but just aren’t that big.

All of the SF-B2969, ASUNA 4200 and SF-B2883 bikes have water bottle holders, which is great for some mid-exercise hydration. The other two bikes do not have such holders, which is a tad bit unfortunate.

All of these bikes also have media trays onboard their consoles/monitors. These holders do mean that you won’t be able to see the top of the monitor (which is the heart rate screen), but you can always just look underneath.

Finally, the only place that you can find speakers is the SF-B2969. This is rather unfortunate, but you also can’t really expect such a feature on the cheaper bikes.

What We Think of Sunny Upright Exercise Bikes

This is actually a pretty good collection of upright exercise bikes. They are all relatively cheap compared to other options, while each offering good resistance and technology. The comfort could be improved, but that’s to be expected from Sunny Health & Fitness. We would probably recommend going just that little extra bit further to get either the SF-B2969, the ASUNA 4200 or the SF-B2883, as they offer just better consoles and a little bit smoother resistance. Or if you can afford, we would highly recommend you to consider one of the Nautilus upright exercise bikes as they offer much more in terms of technology and comfort. The other two are good cheaper options, but at that price point (or even cheaper) you could also be looking at other options such as Marcy upright bikes. That concludes our comparison of these Sunny Health & Fitness Upright Bikes. Hopefully you have learned something new and can now make a better judgement about which (if any) of these bikes you’d prefer. Now get out there and get cycling!
