Powerful yet pared down, the JLL IC400 PRO measures 130 x 54 x 141 cm and slides sleekly and tightly into any space with ease, making it a versatile and compact piece of equipment.

Pro Digital Monitor

  • This indoor cycling bike runs on batteries (included) so no need to power plug-in.
  • The monitor tracks rider’s Watt (estimation, not accurate but better than nothing) RPM, Speed, Time, Distance, Calories, and Heart Rate (via pulse sensors and Bluetooth HRM).
  • There is Bluetooth technology that enables the bike to connect with the “iconsole+” app which comes in handy if you want to track your rides.
  • There is also preset programs which is a great plus considering the price point.

This high-tech digital monitor is simple and easy to use but also features high-tech and intuitive components, making it the perfect blend of utility, functionality, and overall workout support. The monitor itself built right into your bike for maximum efficiency and feedback, situated centrally in the handlebars for easy access. The seven function console offers streamlined and accessible feedback for every ride. The direct power measurements achieved through fitness tracking built into the cycle include time, speed, distance, watts, calories, pulse, and rotations per minute, allowing you to track every element of your spin ride. You can monitor your cadence using the included pulse sensors to track individual spin and pulse rotations as well.

As a bonus, the device enables Bluetooth connectivity, meaning that it is iConsole app compatible and can allows to track workouts. However, it has limited app compatibility, a warning sign that means that your workout data cannot instantly be connected and saved to apps like Zwift, Peloton, or other leaderboard system. The built in tablet mount means you can watch an episode of your favorite show or movie or follow along to a spin class for maximum power and convenience during your rides on your own device.

Pedals and Q Factor

  • Metal pedals have toe cages for regular gym sneakers
  • SPD compatible for proper indoor cycling shoes
  • Q-factor of 170 mm (very good length for most riders)

The pedals included on the JLL IC400 PRO bike are top-notch and designed to work with multiple styles of cycling. One level, they’re simple bike pedals with included toe cages to keep your feet from slipping off the pedal mid stride. However, they are also SPD compatible, a big bonus for professional or experienced riders who prefer the power and precision of SPD pedals and work.
SPD is a must-have for any cyclist because of its wide variety of personalized features. Most SPD pedals are double sided – that means you can clip into either side of the pedal, which makes starting from a stationary position a lot easier.

Some riders prefer the additional security that comes from knowing that you need to push hard to move the flywheel (and having more resistance to stabilize you while you pedal) but if you’re just starting out as a cyclist you may want less tension and a more “normal” pedalling feel. For beginning riders, being able to ease your way into training with SPD compatibility is a big success factor if you’re looking to increase your spinning abilities, or if you’re just looking for a standard indoor bike these pedals will do the trick.

The q-factor on the JLL IC400 Pro bike is 170mm, a wide q-factor stance. The JLL IC400 Pro is wider set, with a measuring distance of 170mm between pedals, a q-factor that will set riders up for limited ergonomic success because it doesn’t minimize pedalling strain on the body. A narrow stance is generally preferred for spin bikes because it positions the feet and knees in a line that drives smoothly downwards, allowing maximum drive on the pedal and creating ergonomic positioning for legs and knees that reduce strain on joints and other muscle functions especially when you’re leaning or moving around on the bike. This wider set pedal distance means your knees are unbalanced and your legs will be driving at a bowed angle, which isn’t ideal for maximum efficiency but can work for some riders!

JLL IC400 PRO Flywheel

  • JLL IC400 Pro is equipped with a 22 kg fixed flywheel
  • Weighted, forward momentum pedaling
  • Uses sleek and quiet magnetic resistance
  • Magnetic, no contact braking systems

Magnetic resistance systems like the one featured on the JLL IC400 are a staple in the spin fitness industry because of their seamless, no contact connection between flywheel and transmission. The JLL IC400 Pro flywheel is made up of multiple magnets that work together to weigh down the flywheel as it spins, thus generating equal traction and resistance as you spin, but because they’re no-contact, braking is easy and causes no damage to your machine or unpleasant jerk to your body. The fixed flywheel works hard by pedalling smoothly forward and generating force that propels the pedals forward as you push, meaning you work harder with every stride to earn a good workout.

The heavy-duty drive belt system, flywheel, and strong frame on the JLL IC400 make this bike reliable and durable, preserving the function of your flywheel and transmission system no matter how many intense rides you complete. The flywheel, similar to the rest of this bike, is built to withstand any amount of use, so you’ll have no problem riding it for many years or taking it with you if you move homes, apartments, or gym spaces. The flywheel also features a durable bumper to shield your walls from damage and protect the health and longevity of the flywheel.

JLL IC400 PRO Resistance

  • JLL IC400 PRO features a standard magnetic adjustable resistance system
  • Variable incremental adjustment knob adjusts resistance before or during rides with just a simple rotation
  • This bike used a dial system and doesn’t track resistance levels.
  • JLL IC400 PRO comes with manually adjustable resistance which means no automatic resistance adjustment.

Similar to JLL IC300, the JLL IC400 PRO indoor cycle uses proven and reliable magnetic technology to shape personalized approaches to adjusting the degree of magnetic resistance. Instead of having a set amount of resistance levels like other pieces of fitness equipment, the JLL IC400 spin bike features an variable adjustment knob that allows a rider to adjust the resistance settings by twisting the knob in degrees in whatever direction you’d like without a dramatic change or excessive time tinkering with settings.

This resistance knob has many advantages, primarily that it’s easy to adjust mid workout, unlike other bikes where you can only adjust your resistance level after you’ve stopped pedaling. However, the lack of distinctive or preset levels can be a challenge and difficult to manipulate if you’re in a workout that needs a fast resistance switch that you can’t achieve through slow transitioning through each level. Variable resistance changes are usually best suited for longer cardio-based or endurance style rides, but partly because of the magnetic no contact system, this specific bike offers slightly faster adjustments that can help with hill, terrain, or interval training if that’s what you’re looking for.

Handlebars and Seat

  • Height adjustable and latitude adjustable elongated handlebars.
  • Four-way adjustable comfortable padded seat.
  • JLL IC400 PRO includes a free spin bike seat cover which comes very handy for longer rides.

The handlebars on the JLL IC400 PRO are elongated and curved for comfortable and ergonomic extended use as well as being highly functional and boasting very few limitations. The handlebars are easily adjusted thanks to a fore-aft lever and an up-down knob to control height. The handlebars feature the included electronic console for ease of access, as well as being equipped with a tablet and/or phone mount. Located alongside the JLL IC400 is a conveniently located water bottle holder for ease of access throughout your workout.

The padded, comfort style saddle on the JLL IC400 PRO indoor spin bike is similarly personalizable and versatile. Featuring height adjustments, this bike can fit a variety of different rider heights. Most sizes of riders will feel comfortable on this bike with this comfortable saddle that shifts up and down as needed. You can also change the forward and backwards positioning of the saddle, making it an even more customizable ride. For riders who need total flexibility with their spin cycles, this kind of adjustability is a big plus. It also makes it easier to switch between users of different sizes and shapes with quick lever and knob adjustments.

JLL IC400 PRO Transmission

The JLL IC400 PRO features a signature rubber-belt transmission system that’s both high-performing and low maintenance, providing an ideal ride for every user through its use of a tough and sturdy rubber drive belt. Belt systems in general require significantly less effort to maintain than chain drives (the type of resistance you’d see on a standard outdoor bike), but the rubber JLL belt drive innovates even further on this concept by eliminating traditional maintenance steps like lubrication, tightening, and rust-prevention. The rubber belt drive (also known as the transmission belt) provides a superior drive and ride experience, including a tight fit to the gears and the smooth overall ride.

Pedaling this bike is a silent yet power-driven experience that creates a strong drive and tough resistance that will challenge you during any workout. The gear ratio is another major contributor to smooth and quiet rides: the ease of adjustment with the knob-based resistance system contributes to the overall silence of your ride and eliminates the loud cranking and creaking that some older spin bikes or outdoor chain bike models are known for while also making resistance changes feel effortless.

JLL IC400 PRO Price and Warranty

  • The JLL IC400 PRO bike is currently priced at £520 (considered great value for the price)
  • The JLL IC400 PRO bike’s warranty includes a simple twelve months on everything and is in ROHS CE compliance

For warranty questions or parts replacement, you can contact the JLL manufacturers through their Amazon store here: “”

The price of this bike in comparison to the range of features it offers and the range of other bikes available is excellent, as it includes a top-notch Bluetooth compatible monitor and SPD pedals. These are definitely mid-range bikes that are best for spinners on a budget or hunting for a bargain and who are at any level of expertise in the spin world.

Assembly and Shipping

  • Shipped two separate boxes that weigh between 9 and 50 kg with partial assembly required
  • Takes about ten days to arrive depending on your location
  • Includes all tools needed for assembly plus a water bottle and seat cover
  • Parts that need assembly are; front/rear stabilizers, pedals, seat, handlebars, and monitor.

Assembling your JLL IC400 PRO Indoor Cycle is simple and easy to figure out with the assistance of the included manual and manufacturer guidance. The key and more complex parts, such as the flywheel and the belt system, come pre-assembled, so you won’t need to worry about how to attach them.

However, if you’re nervous by the idea of assembly, you can purchase labor services to come to your home and assemble the bike depending on your location for an additional fee. Otherwise, grab a friend and the instruction manual and get to work (spin bike assembly is pretty straight forward and easy)! Shipping timeframes will depend on the carrier, but if you have concerns about getting it into your house you can call ahead and arrange assistance with your local delivery system.

JLL IC400 PRO Indoor Cycling Bike Pros:

Powerful and efficient:

This is one of the highest-quality mid-range exercise bikes on the market, and for good reason. JLL has a history of offering affordably priced bikes that top the spin bike charts both in performance and design. The IC400 is portable and easy to store, but it also provides a powerful ride for users while maximizing ergonomic and aesthetic design and keeping the price tag fair.

The Rubber Transmission Belt:

The rubber JLL IC400 PRO belt transmission is an extremely reliable and important addition to any indoor cycle. Both the durability and silent performance of the JLL IC400 PRO belt mean that it performs at a high degree consistently over a long period of time, so you won’t have to worry about maintenance or performance issues for a while after you purchase it. The no-slip, no-jerk drive you achieve thanks to the belt’s stretchy rubber flexibility is another big advantage, creating an innovative and smooth ride every time.

Strong Resistance:

The variable magnetic resistance system is another top factor for this bike. The no-contact braking and no slip drive belt work together to make a smooth and intense workout that JLL is known for, and the seamless transition between the gear system and the resistance knob allows for perfect adaptability to your needs and a truly personalized workout. The magnetic system is also highly durable, meaning that your bike’s lifespan is longer than normal and can stand up to years of regular and intensive use without sacrificing any of the performance quality of your resistance system or requiring a lot of maintenance.

SPD Pedals:

The inclusion of SPD-integrated pedals is also a big advantage. SPD is a huge component of spin and cycling, so having pedals that are compatible with cleats or other elements of the SPD pedaling system feels like a major win especially at this price point.

JLL IC400 PRO Indoor Cycling Bike Cons:

Limited App Connectivity:

The lack of ANT connectivity limited Bluetooth functionality are probably the biggest negative to this bike. Not being able to automatically sync it up with apps like Zwift or Peloton is a miss in our book, especially considering there are already built-in Bluetooth. Being able to link your bike up to any top fitness app would go a long way in terms of fitness options. Though you can easily add in ANT cadence and speed sensors with third-party options, it’d be nice to not have to spend the extra cash right away and that they’d simply be included with the bike.

No automatic resistance:

The JLL IC400 Pro indoor bike boasts of magnetic resistance, which is a superior alternative to friction resistance because it is silent and virtually maintenance-free. However, it’s important to note that this bike doesn’t have automatic resistance adjustment capabilities, which means that apps like Kinomap won’t be able to control the resistance levels automatically. So, you always need to manually adjust the resistance levels using the bike’s control knob to suit your workout needs.

Our Final Verdict

The JLL IC400 PRO Spin Bike is a good quality spin bike for any level of spinner that would fit well in any personal gym or workout space. The versatile design, adjustable frame, and durable build mean this bike can stand up to any kind of ride by all types of riders. The JLL IC400 PRO offers a lot of good performance capabilities, especially when it comes to its drive, SPD pedals, and flywheel/resistance combination. Tech features like the Bluetooth monitor add a cherry on top to this already good quality machine. For its price point, the JLL IC400 PRO indoor spin bike is absolutely a strong contender for anyone ready to dive into or recommit to the world of spin. Its strong and durable resistance system ensures continually intense workouts that are always working to better you and will likely last you many years. Beginners who are looking for a good entry into spinning or advanced spinners used to high-quality spin bike features will all likely find this bike worthy in terms of features and price, making it a great purchase.
