Frame construction
Since it’s a bike designed for spin workouts, the Efitment Streamline IC037 features a sturdy construction.
Its frame is made of steel tubing coated with a corrosion-resistant paint finish. The colors used are metallic gray for the main frame and black for the seat and handlebar posts. The flywheel is chrome-plated with ABS side covers. The only other ABS plastic parts in the bike’s construction are the belt cover and the brake cover.
The bike’s frame is triangular for improved sturdiness but doesn’t have the standard design with straight bars. The main oblique tube is slightly curved for improved aesthetics. Also, most bars in the bike’s construction are ovalized. The only exceptions are the slider of the seat which is rectangular, and the handlebar which features cylindrical tubes.
Similar to the Efitment IC029, the Streamline IC037 exercise bike has the short horizontal bar that unites the seat tube and the main curved tube. Although this may seem like an insignificant element, it can be quite a plus for certain spin workouts that require to repeatedly mount and dismount, or perform stretches. Not all spin bikes have this feature.
The fully assembled bike isn’t extremely large. It is only 44″ (112 cm) long, and 21″ (53 cm) wide. Therefore, it can fit pretty well even into a small room. However, it is recommended to allow at least 24″ (61 cm) of clearance all around it to be able to perform any spin workout without any hindrance.
Compared to other spin bikes, the Efitment IC037 isn’t extremely heavy. However, it does weigh approx. 73 lbs (33 kg) which is approx. twice the weight of the average road bike. This weight is reflected in its overall stability. Plus, both its base bars have adjustable levelers while the front base integrates a set of wheels to facilitate its relocation, if necessary.
Seat and handlebars
The Efitment Streamline IC037 indoor cycling bike is equipped with a seat that excels in comfort factors.
To begin with, it is wider than the average spin bike seat providing extra contact surface. It integrates a thick layer of cushioning which considerably reduces the impact on your tailbone. It has a large cutout in the middle which improves breathability. Its cover is made of durable synthetic leather and its rear section features two spring elements that improve its flex.
Another important aspect with regards to the bike’s saddle that we must mention here is its attachment system. The saddle features a standard, collar-type attachment system which allows a slight forward or backward tilt. Not only that, but in case you will ever need to replace it compatible options are also widely available; you can basically find a seat for this bike in any bike shop.
The bike’s seat is four-way adjustable (up, down, forward, backward). Its upright post offers 9 adjustment positions while the horizontal slider adds a few extra inches of front-to-back adjustment. Therefore, the bike can accommodate users with an inseam between 29″ and 36″ (73 – 91 cm). In other words, it should fit users between 5’2″ and 6’6″ (157 – 198 cm), allowing a complete leg extension. Also, the seat assembly is designed to support users up to 275 lbs (125 kg).
The Efitment IC037 is equipped with a multi-grip handlebar. It offers off-road grips, climb-type grips, and flat land grips. It also has a small loop bar in the center which allows a close parallel grip. The side grips feature a layer of rubber foam material for improved comfort. However, they do not integrate pulse sensors.
The handlebar is only two-way adjustable (up, down). Its post has 6 adjustment positions. It does not have a slider like handlebar of the Efitment IC033 model.
Drive and resistance
To begin with, this is the Streamline IC037 is one of the Efitment indoor cycling bikes with a lighter flywheel.
Its flywheel only weighs 22 lbs (10 kg). But nonetheless, it is perimeter-weighted; this design adds inertia which is great for spin workouts.
The flywheel and the bike’s drive system allow reverse pedaling. Therefore, you can diversify your workouts alternating forward with reverse pedaling sessions. It’s also important to mention that the included exercise meter continues to track your workout metrics even when you pedal in reverse.
The Efitment IC037 is equipped with a manual magnetic resistance system. This means it doesn’t need an external power source or an adapter. But on the other hand, it cannot adjust the resistance automatically.
The resistance system consists of a magnetic brake attached to the tension knob on top of the main tube of the frame. By turning this knob clockwise, the magnetic brake moves closer to the flywheel which increases the pedaling difficulty. The brake is “stepless”; in other words, it doesn’t have pre-determined levels. You simply turn the knob until you find the desired pedaling difficulty. It can also be pressed down to instantly stop the flywheel from spinning.
Since it’s a bike designed for spin workouts, its crankset and pedals are designed to support the whole weight of the user. So, as long as you don’t exceed the bike’s weight limit (275 lbs / 125 kg), you should be able to pedal while standing up with no problem.
The pedals are made of durable metallic alloy. They don’t have SPD elements for spin shoes, but do have a non-slip surface and adjustable toe cages. The exact pedal Q Factor (spacing between the pedals) is not specified. However, it’s fairly narrow in order to eliminate any lateral stress on the knees.
Last but not least, this Efitment exercise bike is equipped with a poly-v belt. This means you don’t have to worry about its lubrication. Also, the pedaling motion is almost completely silent and vibration-free.
Exercise meter
The Efitment IC037 is equipped with a basic fitness meter. It’s a small unit featuring an LCD display which 
indicates time, distance, speed, and calories burned. As we’ve mentioned above, the bike doesn’t have any pulse sensors and the exercise meter unit cannot track your pulse.
The meter unit is very easy to use. It only has one button. By pressing the button repeatedly, you can select the workout metric that interests you the most. Also, you can select its Scan Mode which will enable it to rotate all the workout metrics showing each one for 4 seconds. The button also has a reset function. By pressing and holding it for a few seconds you can clear all the values on it to zero.
The meter unit is battery-powered. It requires one AAA battery which is included. It starts up when you begin pedaling or when you press its button, and automatically turns off if it does not detect any activity on the bike for 3 minutes. When it enters its sleep mode, all function values are saved so you can pick up where you left.
Assembly and Maintenance
Similar to most other spin bikes, the Efitment IC037 requires some assembly. Its main body comes pre-assembled, though. Therefore, you only need to attach the two base bars, the seat post, the seat, the pedals, the handlebar post, the handlebar, and the exercise meter. This shouldn’t take more than 30 minutes of your time. The manual provides all the necessary instructions and a basic toolkit is also included.
Since the bike is equipped with a frictionless magnetic brake system and a belt drive system, it doesn’t need any lubrication or brake pad replacement. Therefore, in terms of maintenance, you only need to keep your bike clean and periodically check for loose bolts or parts.
