C535U Frame Construction

The SportsArt C535U upright exercise bike features a heavy-duty steel frame; it supports users up to 400 lbs (181.8 kg), which is impressive for an upright bike. In addition, several durable ABS covers conceal most of the unit’s base frame.

However, all the steel tubes in the machine’s construction have an abrasion-resistant and corrosion-resistant powder coating finish. The color used is gray for most of the frame, except for the seat post.

The bike has a pretty heavy construction. It weighs over 125 lbs (57 kg) with all the parts assembled, more than three times the average road bike’s weight. However, all this weight considerably improves the unit’s stability. Plus, both its bases have adjustable levelers.

The front base of the bike has a set of caster wheels. Therefore, if you need to relocate it once you have finished your workout, these considerably facilitate the task. The bike’s frame does not fold in any way, though.

The fully set up bike is slightly larger than the average upright bike made for home use, such as the Tunturi B35 example. However, it’s far from being a super-large fitness machine. Its footprint is approximately 45″L x 23″W (155 x 58 cm). The highest point is at the top of the console, approximately 56″ (143 cm) above floor level. Therefore, leaving at least two feet of clearance around the unit is advisable for safe operation and access.

Lastly, the SportsArt C535U upright cycle does not have a step-through design. However, the front part of the frame is considerably lower, making it easier to pass over and assume a correct position on the seat.

Seat and handlebars

The SportsArt C535U has a 4-way adjustable (up, down, forward, backward) seat. Its vertical post offers plenty of adjustment positions to accommodate users up to 6’5″ (196 cm). The horizontal slider also provides several inches of adjustment to achieve a perfect position with the handlebar.

The included saddle does not have air cell cushioning; it’s a standard saddle with a high-density, flexible and contoured top. The seat post has a triangular plate to which the saddle attaches via three bolts.

Although it’s not a super-cushioned seat, it still is considerably more extensive than the average seats on most spin bikes.

The seat’s straight bar adjusts via a pop-pin, while the horizontal slider is via the handle at its rear. Thus, horizontal adjustments are possible while you are seated.

The bike’s handlebar is non-adjustable. Instead, it attaches to the short bar fixed bar via four screws, which provide an excellent, sturdy connection. The handlebar assembly has a multi-grip design and a layer of rubber foam material to provide a secure grip.

The bike’s handlebar has no pulse sensors, but the console is compatible with all Polar wireless HR chest straps (not included).

C535U resistance

The SportsArt Fitness C535U upright exercise bike has a self-powered eddy current resistance system. Therefore, you don’t need to connect the cycle to an electrical outlet; it produces the energy required to power up the console and control the internal brake. It also has an internal 12V battery, storing energy created during your workout sessions to power up the console.

The resistance is only adjustable from the bike’s console. However, it’s also automatic; in other words, if you use specific programs, the cycle will auto-adjust the resistance.

The internal resistance elements are a servo motor and a set of magnets built into the flywheel. As you select a certain level of resistance from the console, the motor will adjust the magnets’ pull, ultimately increasing or decreasing the pedaling difficulty.

The bike’s resistance system excels in micro-adjustability; it offers 40 levels of resistance. The first few levels are very light and great for anyone who needs recovery training. Conversely, the 38-40 levels provide quite a bit of difficulty, simulating a hill climb and allowing you to quickly achieve a high cardio rate.

The weight of the internal flywheel is not specified. However, it has a balanced construction and delivers an extraordinarily smooth pedaling motion. It’s also bi-directional. Therefore, you can diversify your workouts by pedaling in reverse.

C535U drivetrain

Like most other upright bikes with a magnetic resistance system, the C535U features a belt drivetrain. Thus, you don’t have to remove the covers to lubricate the bike’s transmission. Also, the belt drive system renders the cycle usage almost entirely silent.

Finally, the bike’s crankset features heavy-duty crank arms and oversized, weighted pedals. However, since it’s not a spin bike, it is not made for pedaling while standing up. Therefore, standing up while pedaling is not recommended even if you’re not a heavy user and the crank arms/pedals can support you with no problem.


This upright exercise bike features an LED display console with three display sections. The top display is the cardio advisor, which indicates your heart rate, the weight loss zone, and the cardio zone. The larger center display shows the profiles of the workout program. Finally, the bottom screen shows the full range of other workout metrics, including calories burned, RPM, the current resistance level, Mets, time, speed, distance, and watts.

The speed and distance are adjustable to either metric units or imperial units. However, you will need a wireless HR chest strap (the console works with all Polar transmitters). In particular, the bike’s handlebars do not have any pulse sensors, so; you will need an HR chest strap (sold separately) to read the pulse.

The bike’s console has Bluetooth connectivity. Therefore, you can sync it with your smartphone or tablet via the SA WELL+ app to track your progress online. It also has 2 USB ports for charging your phone or transferring your workout data manually to your SA WELL+ account via a USB flash drive.

The console has volume controls for iOS devices and a tablet holder under the main keypad in other features.

Workout programs

The bike has ten built-in workout programs. Nine have their quick access key on the console: Quick Start, Manual, Interval, Plateau, Random, Fat Burn, Fit Test, Custom HR, WT Loss, and Cardio. The WT Loss and Cardio programs share the same program button.

Quick Start

The QuickStart program allows you to exercise without pedaling and adjusting the resistance you like while the console displays track of your workout data. The Manual program is similar to the QuickStart program but allows you to select time, distance, and calorie goals.

SportsArt C535U Upright Cycle

The Interval program has three settings. These are 1:1, 1:2, and 1:3. For the 1:1 parameter, the default “work” and “rest” intervals are 1 minute. The “work” interval is 1 minute for the other ones, but the “rest” intervals are 2 minutes, respectively 3 minutes. The resistance and interval durations are customizable, though.


The Plateau program offers a workout with a gradually increasing resistance for 20% of the exercise, followed by a constant resistance level for 60% of the training. With resistance decreasing progressively for the remaining 20% of the exercise.

Random and Fat Burn

The Random program, as its name suggests, generates a random set of resistance profiles every time you press it. Fat Burn is a program designed to help you burn calories. It has 20 levels from which you can select one that corresponds to your fitness level.

Fit Test

The Fit Test program has four segments of 3 minutes; it will compare the actual Watts and the preset Watts in each part and adjust the resistance accordingly.

HR Programs

Finally, Custom HR is a heart rate control program that allows you to set your target heart rate. Next, WT Loss is an HR control program to keep you at the optimum speed for losing weight. And last, Cardio is an HR control program designed for cardio conditioning.

C535U Assembly and Maintenance

SportsArt C535U Upright Cycle

The bike’s main body comes pre-assembled. The drive and resistance parts and the seat post are already attached to the mainframe. Therefore, you only need to connect the rear bottom base, the saddle, the console mast, the handlebar, the console, the pedals, and several other small covers.

Consequently, it may take up to an hour of your time. However, the manual provides clear assembly instructions, so the task is not too complicated. Also, all the tools required for assembly are included.

Maintenance doesn’t require much. You only have to check for loose bolts and parts and keep the unit clean.

4 thoughts on “SportsArt C535U Upright Cycle | 40 Levels of Resistance”

  1. Hi, and thanks for this very informative review. This looks like an excellent machine. I very much like the SA Well compatibility. In my opinion, one of the most significant drawbacks with home gym equipment is maintaining commitment and momentum with a fitness regime because of the lack of a social dimension. Any feature on home training equipment that facilitates connecting with an online trainer or connecting with a community must be positive. My most recent medical test results indicate that I have to get back onto the exercise equipment regularly. From my own experience, it is always boredom that I am battling. Perhaps if I were generating electricity simultaneously, that would at least give me another goal. Thanks and best regards, Andy

    • Hi Andy, thanks for stopping by and sharing with us. You’ve hit on something that confronts us all. BOREDOM! Luckily, technology is removing boredom and motivating us to achieve our goals. Would you please let me know if I can ever be of assistance? I’m here to help.

      Kind regards, Robert

  2. The SportsArt C535U Upright Cycle is one of the best self-generating cardio cycles out there with a multi-options LED console. The fore-mid-aft seat adjustment allows optimum seat positioning, and a unique low-profile shroud allows easy access. The cycle comes equipped with two headphone jacks with built-in volume control, two USB ports for device charging, and an optional iPod & iPhone 30-pin connector. The bottom screen shows the full range of other workout metrics, including calories burned, RPM, the current resistance level, Mets, time, speed, distance, and watts, but you will need an HR chest strap (sold separately) to read pulse. Overall an excellent machine.

    • Hi Preetam, thanks for stopping by and sharing your thoughts with us. Would you please let me know if I can ever be of assistance? I’m glad to be of help.

      Kind regards, Robert
