SB900 Frame Construction

Sole Fitness SB900 Indoor Cycling Bike

The Sole Fitness SB900 indoor cycling bike is for spin workouts. However, unlike most other models, it does not have the standard triangular frame. It’s instead an X-type frame with a slightly higher center of gravity. It has a similar construction to the Sole SB700 model I’ve covered here, but this bike has magnetic resistance.

The bike has a steel tubing frame. It combines oval and cylindrical tubes in its construction for improved aesthetics. The mainframe comes double-coated with a black paint finish (unlike the older versions, which had a burgundy red finish). The seat post, the handlebar post, and the flywheel are chrome-plated.

The bike also integrates several plastic parts. The most notable ones are the drivetrain cover, the brake cover, several other covers, and the tablet holder. These are durable thermoplastic materials.

Like most other spin bikes, the Sole SB900 is not a large fitness machine. Its fully assembled footprint is approx. 42″L x 21″W (116 x 53 cm). It is advisable to allow at least a few feet of clearance all around it for easy access.

The bike is pretty heavy. Its net weight is approx—133 lbs (60 kg). Therefore, two people should carry the box or use a hand truck.

However, once assembled, one person can quickly move the bike. That’s because its front base comes equipped with transport wheels. In addition, its weight provides superior stability, and its base bars have adjustable levelers.

Seat and handlebars

The Sole Fitness SB900 has a four-way adjustable (up, down, front, back) seat. Furthermore, its vertical post offers several adjustment positions, while its horizontal slider adds a few inches of front-to-back adjustment.

Therefore, the bike accommodates users between 5’1″ and 6’5″ (155 – 196 cm). In addition, it also has a maximum user weight limit of 300 lbs (136 kg).

The included saddle is for superior comfort. First, it integrates a thick foam cushioning layer, and its cover combines synthetic fabric with red faux leather. It features a contoured design with a groove in the middle for improved breathability.

It’s also important to note that the bike’s saddle is pretty easy to install and remove. Its attachment system is standard, collar-based. Therefore, you should find a wide range of compatible saddles if you want to replace them.

The bike’s handlebar offers four-way adjustability (up, down, front, back), just like the seat. Its highest position is approximately 45″ (114 cm) above the floor. Its horizontal slider adds several inches of front-to-back adjustment.

The handlebar features a multi-grip design. It offers the possibility to adopt a climbing grip, an off-road grip, a standard grip, and a close parallel grip. You can also adopt an aero grip if you don’t install the tablet holder.

A layer of PVC foam material fully covers the handlebar. Unfortunately, it does not have pulse sensors, but the fitness monitor can read your pulse from a wireless transmitter.

SB900 Drive system

The Sole Fitness SB900 indoor cycling bike has a chrome-plated flywheel featuring ABS side covers. The flywheel has a perimeter-weighted design which is excellent for spinning as it provides a consistent pedaling motion and high inertia. However, it weighs 48 lbs (22 kg), one of the heaviest flywheels on a spin bike.

The bike comes equipped with a belt drive system. Therefore, you don’t have to worry about its lubrication. Also, the belt generates less vibration than a chain, contributing to the ride’s overall smoothness.

The bike’s drivetrain allows for reversing pedaling. However, the resistance remains constant when pedaling in reverse, depending on the selected tension level. Therefore, coasting is not possible on this bike. Also, when pedaling in reverse, the monitor continues to track your data.

The bike comes equipped with a heavy-duty crankset. Its arms are steel-made, coated with a black paint finish, and they’re approx. 170 mm (6.7″) long. Also, the bike’s Q-Factor (spacing between the pedals) is approx. 180 mm (7″) is narrow, so you shouldn’t experience lateral knee stress during pedaling.

The included pedals are made of durable aluminum alloy. They have SPD elements for spin shoes and toe cages. They also have 9/16 threads, so you can easily find replacements if you need to change them.

Resistance system

As I’ve mentioned, the Sole Fitness SB900 bike features a magnetic resistance system instead of the Sole SB700 model, which has a friction resistance system. In addition, it is not a motorized bike, so you don’t need to connect it to a power source.

The bike’s resistance system has a magnetic brake attached to the frame above the flywheel. This brake connects to the bike’s resistance knob on the frame. Therefore, when you turn this knob left or right, the distance between the magnets and the flywheel changes, which leads to more or less resistance.

The bike’s braking system includes a small lever and felt pad. When you press this lever down, the felt pad comes in contact with the flywheel and stops it from spinning. This emergency brake is necessary as the flywheel is heavy, and trying to stop it with your feet from the pedals may lead to injuries.

The main advantage of the magnetic brake is that the magnets do not touch the flywheel. Thus, they don’t wear out, and the flywheel spins freely, leading to a smooth and quiet pedaling motion.

SB900 Fitness monitor

The Sole Fitness SB900 indoor cycling bike has a fitness monitor that offers a few extra features over a simple one. To begin with, it features an LCD divided into several sub-sections to show as many workout metrics as possible at once. It tracks time, speed, distance, RPM, calories, and pulse.

The bike has no integrated pulse sensors, so the monitor can only read your pulse if you wear a wireless (ANT+) HR chest strap. Unfortunately, this accessory does not come with the bike. In addition, the speed and distance can be metric units or Imperial units.

The fitness monitor is pretty easy to use. It has two buttons. The left button covers the Mode/Reset functions, while the right button covers the Start/Confirm functions. Unfortunately, the monitor does not have pre-set workout programs and plays no role in the bike’s resistance adjustment.

However, you can set a heart rate target with an alarm to keep yourself in a specific HR interval. In addition, you can input your weight and gender for a better calorie calculation. The monitor also has a clock function that displays when the unit is idle.

The fitness monitor is battery-powered, and it requires two AAA batteries. The internal RPM sensor is also battery-powered and requires two AAA batteries. The fitness monitor starts recording your data when it detects flywheel movement. It also enters idle mode after a few minutes of inactivity on the bike.

Assembly and Maintenance

The flywheel, the crankset, the drivetrain, and the magnetic brake are pre-assembled. Then, you only have to add the two base bars, the handlebar, the seat, the pedals, the fitness monitor, and the tablet holder.

Therefore, it shouldn’t take more than one hour of your time. The manual provides step-by-step assembly instructions; an essential toolkit also comes with the bike.

For maintenance, you only have to keep the bike clean. The drivetrain and the brake do not require lubrication. Other than this, it is also advisable to periodically inspect the bike to ensure all the fixed parts hold in place and the moving parts still function correctly.

  1. Thanks for the in-depth review. As someone who uses indoor bikes, this one seems to be a perfect option. It appears to have almost everything you require, although I note the need for an external HR chest strap. In addition, the large fly-wheel would assist in a smoother ride and more accuracy in the power output. I also like the fact that the components have a lot of standardization and so you can swap out things such as the seat if you prefer something different.

    The screen seems easy to use, with plenty of essential options to achieve your cycling & fitness goals. Your rating of 8.5/10  seems to suggest this is an excellent choice as an indoor exercise bike.

    • Hi Richard, thanks for stopping by. Would you please let me know if I can assist you with the Sole Fitness SB900 bike or any other exercise equipment? I’m always happy to help.

  2. Hi Robert, thanks for a thorough review explaining all of the features of the Sole SB900 indoor cycling bike. You might want to change your title to indoor or outdoor cycling because at the very beginning,g you say you can use the cycle indoors as well as outdoor.

    And I love the review of this bike. It’s quiet, adjustable, has an emergency brake, and efficiently controls the flywheel spinning. Also, I like that you explain every detail about the bike. And this way people will be more confident when making the order. Thanks for such a great review.

    • Hi Claudia, thanks for stopping by. I mentioned that you could use the bike outdoors but let me clarify. I meant for only in good weather. Furthermore, I would not leave the bike outdoors after use. The included transport wheels make it relocation easy.

      Would you please let me know if I can further assist you with the Sole Fitness SB900 or any other exercise equipment? I’m always happy to help.

      Kind regards, Robert

  3. This looks like a moderately priced home fitness bike.  A few things I look for in a bike like this are the saddle, which looks good, the range of motion up and down for the saddle bar, and the handlebar shaft.  This is really important if you will log long workouts of sitting, standing, or hunched over the bars (position 3).  I like that it has cages of toe clips.  Another criterion for a bike like this and at over $700, I doubt it’s an issue.  I really get frustrated with a jerky-jerk ride when I’m trying to ride standing up.  A lot of range in the handlebar shaft can help minimize this.  The bottom line is that I like this bike.  It would be a good upgrade from mine.   Warren

  4. Thanks for this exciting and very in-depth review. I  have enjoyed indoor cycling for as long as I remember. With that said, this bike seems like something I should be getting sometime soon. It seems to have things I want and be useful for me in the end. Because of that, I will be sharing with other people who enjoy cycling. 

    • Hi Kiersti, thanks for stopping by. Would you please let me know if I can assist you with the Sole SB900 bike or any other exercise equipment? I’m always happy to help.

  5. Spin cycling is something that I haven’t done…and I’m not sure if I ever will, but this bike option seems like the right choice. The body looks durable to outlast miles of cycling without the numb butt from an uncomfortable seat. The fact that the seat is ergonomic shows that comfort is their top priority.

    The resistance dial showcases many tension options for the optimal leg-day burn. The handlebars look like they can handle added weight comfortably with their elongated, curved design, while the display screen keeps track of progress. In addition, they can connect your device for a full range of tracking vitals during the workouts. This is a perfect option for those with health issues which need to keep track more diligently, like heart rate and triggering heart conditions.   

    • Hi Jeremy, thanks for stopping by and sharing your thoughts with us. Please let me know if I may further assist you with exercise equipment. I’m always happy to help.

      Kind regards, Robert
