Is the Life Fitness IC4 indoor cycling bike one of the best in its class?

The Life Fitness IC4 indoor cycling bike combines inviting modern design with high-grade mechanical components, making it one of the best premium bikes in its class. The belt drivetrain and magnetic brake system are virtually maintenance-free and provide a superior ride.

Service-free technology provides a substantial resistance range. Vertical lever provides tactile feedback and allows for quick adjustment. The bar is easy to reach from all riding positions because it’s beneath the handlebars. The drive-belt requires limited maintenance, improves pedaling technique, permits less momentum-based recovery, makes the rider work efficiently, and operates quietly.

The IC4 saddle has four-way adjustments (saddle height, saddle fore/aft) to ensure a finely-tuned fit for all riders. Additionally, the IC4 has a high-grade aluminum seat and handlebar posts with protection inserts that reduce weight and extremely.

The IC4 handlebars are for comfort and performance. They, too, offer 4-way adjustments (handlebar height, handlebar fore/aft). The design provides a soft, durable rubber grip with innovative bar-ends featuring a natural curve for comfortable hand positioning over the top. The handlebar integrated user-assist technology makes adjustments smooth and easy.

IC4 Frame

The Life Fitness IC4 indoor cycling bike is designed to support any spin workout. It features very sturdy construction with a frame made of durable steel tubing, except for the seat and handlebar posts, which are high-grade aluminum.

All the steel parts in its development come with a corrosion-resistant and abrasion-resistant paint finish. Most of the core frame of the unit features solid ABS covers, which prevent sweat from reaching the paint finish. Also, these covers give the bike a very professional aspect, which can be quite a motivation factor.

The bike features a V-frame design that offers two main advantages. One, the bike has a low center of gravity, which considerably improves its stability. And two, when the seat and handlebar post extends, the distance between the saddle and the handlebar also increases.

Its overall weight enhances the bike’s stability. With the frame fully set up, this Life Fitness exercise bike weighs approx. 110 lbs (50 kg), which is more than twice the weight of the average mountain bike. Plus, both it’s base bars come with adjustable levelers that have large rubber pads.

Due to the rear-drive frame design, the Life Fitness IC4 is slightly larger than other spin bikes. It measures 52″ (132 cm) in length and approximately 21″ (52 cm) in width. It’s advisable to leave at least two feet of clearance on the sides and at the rear, and at least one foot of clearance at the front, for safe operation.

Accessories

In terms of accessories, there are two that come the IC4. One is the dual bottle holder, which integrates into the handlebar. The two bottle slots are large enough to accommodate any hydration bottle. The other is the phone holder, which is between the two bottle holders.

It features a plush pad to provide better stability for your phone. The whole bottle holder/phone holder assembly is a thick sheet of ABS material.

This indoor cycling bike does not include a fitness console.

IC4 Seat

The Life Fitness IC4 comes with a comfort spin saddle almost identical to the one on the BodyCraft SPT-Mag bike. It integrates a thick layer of padding, especially in its rear section, and has a center cutout to improve breathability.

Its surface is a durable, sweatproof vinyl material. Also, its attachment system to the slider is standard, which means that compatible options are widely available, in case you will ever need to replace it.

The seat offers 4-way adjustability (up, down, forward, backward). Its upright post offers 23 adjustment positions, with approx. 1″ (2.5 cm) in-between. Its horizontal slider has 20 mode front-to-back adjustment positions with approximately 1/2″ (1 cm) in between.

On top of that, due to the V-frame design, the distance between the handlebars and the seat increases as well when you extend them. Therefore, the bike can accommodate with no problem users between 5’0″ and 6’7″ (153 – 201 cm), allowing a complete range of motion.

Handlebars

Just as the seat, the handlebar assembly offers 4-way adjustability (up, down, forward, backward). Its upright post offers 15 adjustment positions (1″ in-between), while its horizontal slider offers ten front-to-back positions (1/2″ in-between). It features a multi-grip design with integrated aero bars. It’s utterly rubberized to provide a secure and comfortable grip.

One important feature that needs mentioning regards the horizontal adjustment system of the seat and handlebars. Both sliders have levers (not knobs), which can easily be unlocked when turned sideways.

Therefore, you can easily open and re-lock the saddle or the handlebar assembly to adjust them forwards or backward even if you are already on the bike. Not many bikes offer this feature and require you to pause your workout and dismount to make the correct adjustments.

IC4 Resistance system

The Life Fitness IC4 indoor cycling bike is equipped with a manual magnetic resistance system. This means you don’t have to connect it to a power source to benefit from resistance adjustments.

Its resistance system consists of a magnetic brake placed at the covered section of the flywheel. This brake is attached to the tension lever placed on the handlebar post.

Life Fitness IC4 indoor cycling bike

By pressing this tension lever down, the magnetic brake covers a more significant portion of the flywheel, which results in greater pedaling difficulty. Conversely, if you lift the bar up, the magnetic brake moves away from the wheel, leading to less resistance.

The tension lever does have markings on it which delimit each difficulty level. There are more than 30 markings on the bar, and of course, more than 30 distinct resistance settings. Thus, the bike provides an exceptional micro-adjustability when it comes to pedal tension.

The tension lever also functions as an emergency brake. You can press it down to stop the flywheel from spinning. This may be required in some instances because the pedals turn for as long as the wheel is spinning.

Drive system

This Life Fitness exercise bike comes with a balanced flywheel. Its exact weight is not specified. However, considering its diameter, its weight should be between 35 lbs and 45 lbs (15.5 – 20.5 kg). Its weight shouldn’t matter that much, though, because the bike’s resistance system uses a magnetic brake, not a friction brake.

Therefore, the resistance remains constant throughout a full rotation. More importantly, it rotates at 10:1 of your pedal stroke, which results in high inertia, perfect for spinning workouts.

The flywheel is bi-directional. It offers the possibility of pedaling in reverse. This way, you can diversify your workouts. However, it’s essential always to use the emergency brake when you switch from front pedaling to backpedaling and vice versa, to prevent any injuries.

Like most other exercise bikes with a magnetic resistance system, the Life Fitness IC4 features a belt drivetrain. It uses a durable poly-v belt, which delivers a very smooth and quiet pedaling motion. It also does not need any maintenance. On the contrary, it’s recommended to keep away any lubricants from it, to prevent it from slipping.

IC4 Crankset and Pedals

The bike is equipped with a heavy-duty crankset, featuring steel crank arms and metallic alloy pedals. Thus, it can withstand any spin workout, including standing up on the pedals, even if the user is close to the maximum weight capacity (330 lbs).

The pedals are dual-sided; they have toe cages on one side and SPD clips for spin shoes on the other. They also have standard threads (9/16), so compatible replacements for them are widely available.

Last but not least, the Life Fitness IC4 features a narrow Q-Factor (spacing between the pedals) of 155 mm. Therefore, your feet are on the pedals in a natural position. Thus, the pedaling motion does not generate any extra lateral stress on the knees and ankles.

IC4 Assembly and Maintenance

The core frame of the bike, with its drive and resistance elements, comes already assembled. You only need to attach the two base stabilizers, the seat, the handlebars, and the pedals.

This shouldn’t take more than 20-30 minutes. The manual provides precise assembly instructions. However, the box does not include the required tools for the assembly; you will need a set of Allen wrenches and an adjustable wrench.

This exercise bike requires very little maintenance. It is recommended to keep the frame clean. The seat and handlebar sliders and posts may require a bit of lubrication for smooth usage. Other than this, a periodic check for loose bolts and parts is a good idea.

  1. The ic4 looks pretty good. It must be cumbersome with those fat frames there. I like the way it looks, though, and I must say that it is very nice that it does work well. One thing that seems to be a turnoff for me, though, is the fact that the tools that are meant to be used to assemble the bike are not (included), and this automatically means that I will have to assemble them with the help of someone with tools. That’s an extra cost there.

  2. My aunt has this bike, and it’s pretty nice and easy to use. No confusion causing and convoluted features, just a robust home exercise bike. I’ve only used it a few times, and it worked good for my HIIT training, and I had no problems with the Life Fitness IC4 indoor cycling bike.
