S3 Frame construction

YESOUL S3 Indoor Cycling Bike

The YESOUL S3 indoor cycling bike features a triangular frame construction. Its frame incorporates thick tubes, has a curved longitudinal base bar, and features superior aesthetics. The frame is carbon-steel tubing double-coated with a corrosion-resistant black paint finish. Furthermore, the bike is available in white. Both versions have the same specs and features.

For example, the bike is not extremely large and bulky compared with other fitness machines, such as treadmills or front-drive ellipticals. However, with all the parts assembled, it is approximately 40″ (101 cm) long and 20″ (51 cm) wide.

Also, its highest point, with the handlebar extended up, is 51″ (130 cm). Therefore, it is advisable to allow a few feet of clearance around the bike for easy access and safe usage.

The bike is not super heavy compared with other spin bikes. One of the main reasons is that the integrated flywheel only weighs 16.5 lbs (7.5 kg). Thus, the bike’s net weight is approx—68 lbs (31 kg). For instance, one person can carry and assemble the bike. Also, relocation is easy once built as its front base features a set of transport wheels.

Although the bike is not too heavy, it offers superior stability. One of the main reasons is its low center of gravity. Plus, both its base bars feature adjustable levelers with large rubber pads. Thus, it is not necessary to place and use the bike on a mat. However, it is advisable.

Seat and handlebars

The YESOUL S3 indoor cycling bike includes a saddle designed for superior comfort. It features a gel top cover, integrates a layer of foam padding, and has a durable inner shell made of nylon material. In addition, its top has contours with a median groove for improved breathability.

It’s also essential to note that the seat features a standard, collar-based attachment system. Therefore, if by any means you manage to wear it out, or you want it replaced, compatible options are widely available.

The bike’s seat is four-way adjustable (up, down, front, back). Its vertical post offers multiple adjustment positions with a span of 31″ – 40″ (79 – 101 cm) from the floor. The horizontal slider also adds several inches of front-to-back adjustment.

Thus, the bike can comfortably accommodate users between 4’11” – 6’2″ (150 – 188 cm). Taller persons can still use this bike, but they may not benefit from a complete leg extension. Also, the bike has a maximum user weight capacity of 265 lbs (120 kg).

The YESOUL S3 bike features a multi-grip handlebar. It offers the possibility to adopt a cruise grip, a standard grip, a close grip, and a climbing grip. In addition, it has a layer of high-density foam for an improved grip. Unfortunately, it does not have pulse sensors, but a Bluetooth heart rate armband comes with the bike.

The bike also includes a large polypropylene tablet holder that attaches to the handlebar’s front section. This accessory is large enough to accommodate any tablet up to 11″ in diagonal.

Even though the bike’s handlebar is only two-way adjustable (up, down), it offers nine adjustment positions from 46″ to 51″ (117 – 130 cm) above the floor. It does not have a horizontal slider like the seat for front-to-back adjustment.

S3 Resistance system

The YESOUL S3 indoor cycling bike comes equipped with a manual magnetic resistance system. Therefore, you don’t need to connect it to a power source, and you don’t need a power adapter or power cord for it. But, on the other hand, the bike does not adjust the resistance automatically.

The bike’s resistance system consists of a magnetic brake attached under the main oblique tube of the bike and to the tension knob. Therefore, when you turn the knob clockwise, the magnets move closer to the flywheel, which increases the pedaling difficulty.

The main advantage of a magnetic brake is that the brake pad does not touch the flywheel. Thus, the pedaling motion is drag-free, seamless, whisper-quiet, and maintenance-free.

YESOUL S3 Indoor Cycling Bike

The bike’s tension knob does not have pre-determined resistance levels. However, from the lowest resistance point to the highest, there are approx—100 levels of difficulty. As a general idea, with the magnets as close as possible to the flywheel, the pedaling motion delivers quite a bit of difficulty, simulating a steep climb.

Last but not least, the bike’s brake features a small rubber pad in the front. Therefore, if you need to stop the flywheel from spinning, press the emergency stop on the tension knob. This emergency braking feature is necessary because stopping the flywheel any other way is not advisable and can lead to injuries.

Drive system

The YESOUL S3 exercise bike comes equipped with a 16.5 lbs (7.5 kg) flywheel, which is light compared to other spin bikes. However, it does have a perimeter-weighted structure for improved inertia, which is excellent for spin workouts.

Also, since the bike comes with a magnetic brake, the top resistance levels still deliver a very consistent pedaling motion and high levels of difficulty.

The flywheel is bi-directional; thus, you can pedal in reverse if you want. However, the bike’s drive system features a standard exercise bike construction, so you cannot coast on it. Also, when pedaling in reverse, the resistance remains constant, given by the difficulty generated by the magnetic brake.

The crankset features a large thermoplastic pulley with nylon-coated steel arms. The included pedals are metallic alloy, and they have an anti-skid design and toe cages for extra thrust. Unfortunately, they do not integrate SPD elements for spin shoes. However, their threads are standard 9/16, so compatible options are widely available.

The bike’s drive system uses a poly-v belt resistant to stretching and abrasion. This belt drive system comes with several advantages over a chain drivetrain. First of all, you don’t need to worry about its lubrication. Second of all, it generates slightly less vibration than a chain. And third of all, you won’t have to deal with problems such as stiffened chain links.

S3 Fitness app and Bluetooth connectivity

The YESOUL S3 indoor cycling bike does not include a fitness monitor. However, it has a built-in Bluetooth module that allows you to sync your bike with your smartphone or tablet via the YESOUL Fitness app. All you have to do is scan the provided QR code to install the app, register, and then use the app’s interface to monitor your workout data.

The app shows multiple workout metrics, including time, distance, speed, cadence, pulse, and more. Of course, to read your pulse, you also have to wear the provided wireless HR armband.

The YESOUL app also offers 255 minutes of scenic cycling, several courses of endurance fat burning, and online workout data tracking. Furthermore, the bike is also compatible with other similar fitness apps, such as Kinomap, Zwift, and Apple Fitness+. Unfortunately, it is not compatible with the Peloton app (at least not so far). So, if you already have a subscription to these apps, you can sync your bike with them.

The internal Bluetooth module is battery-powered. It requires 3V “button-type” CR2477 batteries, which come with the bike. Its located at the top of the handlebar under the insulation strip.

S3 Assembly and Maintenance

The main body of the bike comes pre-assembled. So, you only need to attach the two base stabilizers, the pedals, the handlebar tube, the handlebar, and the device holder.

Therefore, it shouldn’t take more than 30 minutes of your time. In addition, all the necessary assembly tools come with the bike, and the manual provides precise assembly instructions.

For maintenance, you only have to keep the bike clean. Since it has a belt drive system, the drivetrain does not require lubrication. Also, since the brake is magnetic, it doesn’t require lubrication or replacement either. So, other than keeping the bike clean, you only have to check for loose bolts and parts from time to time and retighten as needed.

  1. Thank you for your article on fitness bikes! I like how you mention the weight limitation on the bikes and also how much the bikes weigh. My youngest daughter lost a lot of weight using a bike like this. But you have to commit to using it every day! Oh, so that you know, when I clicked the exercising tab, it said the page couldn’t be found.

    • Hi there, thanks for stopping by. I’d be happy to fix the tab you said wasn’t working, but everything I checked is working OK. Would you please let me know if I can ever be of assistance? I’m glad to be of help.

      Kind regards, Robert
