Spirit Fitness XBU55 Upright Bike Review 

The Spirit Fitness XBU55 Upright Bike is a light-commercial grade and residential machine designed to meet your daily physical workouts.  

This is not your average upright bike but one that has some interesting features, very much similar to the SOLE LCB Upright Bike.  

However, the latter has a self-generated power system (no need to be plugged into the power source), and more resistance levels.  

That said, the XBU55 Upright Bike has Bluetooth FTMS connectivity that syncs it to the Fit Spirit app and to third-party apps such as Zwift and Kinomaps. This means you will be able to track workout progress via the app, share results with friends, explore exotic virtual trails, and more.

Frame & Construction 

Spirit Fitness XBU55 Upright Bike

The Spirit Fitness XBU55 Upright Bike is built with a quality thick alloy steel frame that is coated with grey anti-rust paint.  

While the drive system and console covers are made of ABS material. As a result, the unit is elegant and sturdy enough to support a maximum user weight capacity of 350 lbs./158.7 kg.  

Users can easily get on and off of the bike without struggle due to its step-thru design. 

It weighs 100 lbs./45.3 kg which helps it to remain stable even as the stabilizers with adjustable levelers ensure optimum stability. Thus, your workout experience will be free of wobbling or instability despite its small footprint.  

The overall assembled dimensions are 42.5’’ long by 21.7’’ wide by 53.5’’ high. Therefore, the workout area it requires would be 3’5’’ in length (108 cm) by 1’8’’ (55 cm) in width. Plus, additional recommended clearance of 1’ on each side and 2’ at the rear for safety and convenience reasons.  

Transport wheels are integrated at the front base of the bike to enable you to easily have it moved around the room or between storage and workout areas. 

The Seat of the Spirit Fitness XBU55 Upright Bike 

The seat of the Spirit Fitness XBU55 Upright Bike

The seat on this bike is standard. It is more like every other saddle (although larger than a road bicycle seat) with an installment collar that could enable users to easily replace it if they so desire.  

It is cushioned and covered with vinyl material for comfort. However, it doesn’t have springs underneath.

Usually, users purchase a gel seat cover to improve the overall cushioning of the seat. As stated earlier, you can have the seat replaced with any other seat of your choice easily.  

It could be adjusted 4-ways, I.e., fore/aft and up/down adjustability.  

The adjustment is a big deal because it helps you to fit in comfortably, and not all upright bikes’ seats are 4-way adjustable.  

The Handlebar 

The handlebar is nonadjustable. It is attached to the console mast, and strategically positioned to fit all users.  

It is multi-grip designed offering standard grip, parallel grip, race grip, and climbing grip. This means you should be able to alternate workout postures whenever you feel necessary.  

The handlebar is coated with a soft rubber foam material that is intended to provide comfort and a firm grip. Thus, no slippery or calluses will be experienced no matter how long you spend on the bike. 

Also, heart rate sensors are integrated into the handlebar for the transmission of the pulse data to the monitor for your observation.  

The Pedals  

The Spirit Fitness XBU55 Upright Bike is equipped with a set of self-leveling oversized and textured pedals with adjustable safety straps. They are made of quality plastic with a metallic core.  

The pedals are attached to solid crank-arms and a 3-piece crankset. 

Different foot sizes can be accommodated and they are designed to be ridden with standard gym shoes. 

The Q-Factor (distance between the inner left pedal to the inner right pedal) is 9.4’’ while the stride length is 13’’.  

The Drive 

The upright bike has a belt drive system. This consists of a durable quality belt and a 30 lbs./13.6 kg precision-balanced flywheel.  

Thus, the bike’s operation is smooth, quiet, and vibration-free as opposed to a chain-driven bike. You can concentrate on your workout without being distracted by unnecessary noise. Also, it doesn’t matter if there are people around you or neighbors living next door, they won’t be bothered by your workout activity. Isn’t that great? 

Moreover, no maintenance is needed before or after workouts.  

Since the drive system is bidirectional (meaning you can pedal forward and as well in reverse) you can diversify your workouts to engage and tone more muscle groups.  

The Resistance 

The Spirit Fitness XBU55 Upright Bike has an eddy current magnetic resistance system. A resistance system that works when the unit is plugged into a power outlet, otherwise it can’t be operated. 

The +/- resistance buttons on the console have to be pushed to increase or decrease the resistance level or workout intensity. There are 20 adjustable levels available for variant workout challenges.  

The eddy current resistance system comprises a motor servo, a magnet, and the flywheel. The motor servo is responsible for moving the magnetic pad to & from the flywheel without direct contact with any element. But instead, the magnetic pad releases magnetic fields that cause a pull that ultimately generates resistance.  

So, the closer the magnetic brake pad is to the flywheel the stronger the resistance tends to be, and the farther away it is from it, the weaker the resistance becomes.  

As a result, level 1 resistance is weak, and level 20 is very strong, while in-between provides different variations of workout challenges that are suitable for the improvement of cardiovascular health, muscle group toning, and weight loss. 

The Console 

The console of the Spirit Fitness XBU55 Upright Bike

This bike is incorporated with an angle adjustable telemetric console that features a 7.5’’ blue backlit LED monitor.  

The monitor tracks and displays multiple workout stats such as Time, RPM, Calories, Distance, Level, Speed, Segment Time, Pulse, Watt, Program Name, and Lap simultaneously. It has got high visibility that cannot be compromised even when viewed in a room that is not well lit.  

Interestingly, you can track your heart rate by holding into the EKG contact grips or by wearing the included HR chest strap during a workout.  

The console also features 10 workout programs that include Manual, Hill, Fat Burn, Cardio, Strength, Interval, 2 Heart Rate, and 2 User profiles. 

Manual Program allows you to workout based on the resistance level you choose to apply, while the preset programs that include Hill, Fat Burn, Cardio, Strength, and Interval have pre-assigned resistance levels designed to help you achieve their specified goal. However, there is still the possibility to make adjustments if you deem it necessary.  

The 2 heart rates are set for 60% & 80% maximum heart rate zone and can be customized as well, while the 2 User Programs offer you the opportunity to create and save custom workout programs that are re-usable.  


There is a built-in tablet holder (which can accommodate a large tablet device conveniently) on the console and a water bottle holder that is attached to the mast right below the console. These are provided to help you keep a smartphone device and water handy for entertainment and proper hydration purposes. 

Moreover, a cooling fan, speakers, and an MP3 auxiliary port are integrated to make your time spent on the bike enjoyable and productive.  

Although, the cooling fan is not large enough to provide strong air, and if a device is placed on the tablet holder, the display screen could be blocked.  


This unit has a small footprint; hence, it won’t take up too much space even though it is not foldable.  

A storage area with measurements of 3’5’’ length (108 cm) by 1’8’’ (55 cm) width should be good.  

Despite it weighing 100 lbs./45.3 kg, it can easily be moved around the room via the integrated transport wheels at the front base.
