The Efitment IC033 Indoor Cycling Bike is a reasonably new bike, available since the beginning of 2018. It’s an indoor cycling bike designed for spin workouts. It is similar to the Efitment IC031 that I’ve previously reviewed here but has a heavier flywheel, a slightly different frame construction, and a multi-window fitness computer.
The flywheel is considered a heavy one, weighing 44 lbs, and offers a natural ride and consistent momentum. Overall the Efitment IC033 bike produces a smooth pedaling experience thanks to the combination of the magnetic system, belt, and heavy flywheel, resulting in extra stability and smoothness for the pedaling motion.
The computer included with the IC033 spin bike, displays your time, speed, scan, RPM, distance, calories burned, and pulse using built-in pulse sensors on the handlebars. It enables you to see your results to stay motivated and on pace. It is not a high-tech computer which is typical for the price point.
Considering all the features including the 4-way handlebar design, high-quality seat, magnetic resistance, belt, and three-year frame warranty, the Efitment IC033 Indoor Cycling Bike is a good value for the money.

IC033 Frame construction
The Efitment IC033 is an indoor cycling trainer made for spin workouts. This means it has a heavy-duty steel frame designed to withstand the most intense cardio workouts.
It’s a relatively large unit; with the frame fully set up, it weighs approximately 108 lbs (49 kg), which is more than twice the weight of most mountain bikes. All this weight delivers superior stability and overall sturdiness.
But on the other hand, the bike isn’t too difficult to move and handle after its assembled. It’s front base features transport wheels.
In terms of stability, the bike also comes with four adjustable levelers, two on each base bar. These have large rubberized pads that deliver a superior grip on the floor, also preventing the bike from sliding forward, backward, or sideways when you exercise.
The bike isn’t huge compared to other fitness equipment. Its fully assembled footprint is approx. 51″L x 22″W (129 x 54 cm). It is recommended, though, to leave a few feet of clearance all around it for ease of access and to be able to perform even the spin workouts that require you to mount and dismount repeatedly.
The bike is double-coated with a corrosion-resistant and scratch-resistant paint. The primary color used is black for most of the frame, while the Efitment logo is in white/red. The seat and handlebar posts and adjustment sliders, as well as the flywheel, feature a chrome plating.
Seat & handlebars
The Efitment IC033 indoor cycling bike includes a cushioned saddle, similar to the one on the Sunny SF-B1805. It’s a reasonably large seat compared to many other types of spin bike seats, which are typically slimmer. It integrates a generous layer of padding and has two springs at the rear, which considerably improve its overall shock absorption.
The seat is 4-way adjustable. Its vertical post features nine adjustment positions, the spacing between the adjustment holes is approx — 1 inch.
The total adjustment span offered by the upright seat post is between 28″ and 36″ (71 – 92 cm). Plus, the seat can also be adjusted horizontally, and its horizontal slider offers a few inches as well. So, therefore, the bike can accommodate users between 5’0″ and 6’5″ (153 – 196 cm) with no problem.
The handlebar assembly is also 4-way adjustable (up, down, front, back). It doesn’t offer as many adjustment positions as the seat, but this feature can help a lot in obtaining the perfect fit for any user within the height range mentioned above.
The handlebar assembly offers a multi-grip design. It’s urethane-dipped, so it delivers a secure and comfortable grip. It has a large loop aero bar, which adds several grip possibilities. Also, there are pulse sensors integrated at the base of the aero bars; therefore, by holding on to them as you exercise, the bike’s console unit can monitor your heart rate.
IC033 Resistance system
The Efitment IC033 features a standard manual magnetic resistance system similar to the Sunny SF-B1714. It consists of a magnetic brake pad attached to the tension knob on top of the main bar of the frame.
By turning the knob clockwise, the magnetic brake comes closer to the flywheel. This increases the intensity of the magnetic field between the brake and the wheel, which leads to greater pedaling difficulty.
Since the bike’s resistance system is exclusively manual, the bike doesn’t require a connection to a power source. Also, its console unit doesn’t play any role in the bike’s resistance adjustment. It’s only a fitness meter that tracks your workout stats. We’ll cover all of its functions in the section below.
The bike’s tension knob doesn’t have any levels specified on it. You turn it until it generates a satisfying level resistance. As a general idea, with the brake pad at the farthest point from the flywheel, the pedaling motion seems “free,” without too much resistance.
Conversely, with the brake pad at the closest to the wheel, the pedaling difficulty is considerably increased, generating the feeling of a steep climb, or cycling through dunes.
The bike’s tension knob also acts as an emergency brake. You can press it down to quickly stop the flywheel from spinning. This may be required if pedaling with very little resistance, as the pedals continue to turn for as long as the wheel is spinning.
Most exercise bikes equipped with a magnetic resistance system feature a rubber belt transmission, and the Efitment IC033 doesn’t make an exception. It comes with a heavy-duty rubber belt. The main advantages of a belt drive are that it doesn’t require lubrication, it generates less vibration than a chain, and the pedaling is whisper-quiet.
The bike has an extra-heavy, 44 lb (20 kg), chrome-plated flywheel with a perimeter-weighted design — the perimeter-weighting results in more aggressive inertia, which is an essential aspect of any spin workout.
The flywheel generates a steady pedaling motion. It’s also bi-directional; however, when pedaling in reverse, the resistance remains constant, given by the position of the brake pad. Also, coasting is not possible on it.
Since the Efitment IC033 is a bike made for spin workouts, it comes with a heavy-duty crankset, with solid steel crank arms which can hold users up to 275 lbs (125 kg) in a full standing up pedaling position. The pedals are also highly durable, made of metallic alloy.
The pedals are standard, though. They only have toe cages and straps for keeping your feet fixed; they do not have SPD clips for spin shoes. However, their threads are 9/16, so you can easily find replacements for them.
One last aspect to mention here is the bike’s Q-factor (spacing between the pedals). As opposed to other indoor cycling trainers, the Efitment IC033 has a slightly wider Q-factor, which is 190 mm (7.5 inches). Therefore, it may add a little bit more lateral stress on your knees. So, in this case, you may want to have a look at other bikes with a smaller Q-factor, such as the Sunny ASUNA Sprinter 6100 (152.4 mm Q-factor).
The console included with the Efitment IC033 offers a few more features than a fundamental unit. First of all, it has a multi-window LCD, and it shows up to five workout metrics simultaneously. It tracks time, distance, total distance, speed, RPM, calories, and pulse. It also has a clock function.
The unit is not telemetric. Therefore, it cannot track your pulse through a wireless chest strap. To benefit from a pulse reading, you have to hold on to the pulse sensors integrated into the handlebar. Also, speed and distance are in MPH and miles only (there are no metric settings).
The console doesn’t have any preset programs. However, you can select a workout goal for time, distance, and calories. When a goal is (chosen), the console will count down from the selected value until it reaches zero.
The console is battery-powered and requires 2 AAA batteries, which are (included). It starts up when you begin pedaling or when you press one of the buttons. It also has a sleep mode to which it will enter after four minutes of inactivity on the bike.
IC033 Assembly & Maintenance
The flywheel, the belt, the magnetic brake, and the crankset come pre-assembled, already attached to the core frame of the bike.
Therefore, in terms of assembly, you only have to connect the base bars, the pedals, the seat post, the seat, the handlebar post, the handlebar, and the console.
This shouldn’t take more than an hour. The manual provides excellent step-by-step assembly instructions and schematics, and all the tools required for it (are included).
Maintenance requires lubricating the seat and handlebar posts so they can slide easier. A periodic check for loose bolts and parts is advisable. The transmission does not require any lubrication as it’s a belt, not a chain. Other than this, you should keep the bike clean and liquids away from the console unit.
