The PYHIGH S2 is the lighter version of the PYHIGH S7 that we’ve already presented here. It’s an indoor cycling bike made for home use, but does offer a very sturdy construction and can support any spin workout. It’s has a medium range flywheel, and also includes a fitness meter, an accessory that many other spin bikes do not come with.

Frame construction

The PYHIGH S2 indoor cycle features a standard triangular frame, made of heavy-duty thick steel tubing. The main part of the frame is double-coated with a corrosion-resistant and abrasion-resistant paint. The color used is black, with the “PYHIGH” logo painted yellow, these being the only colors available for this bike at the moment. The seat post and the handlebar post feature a chrome finish, which is also corrosion-resistant.

The bike’s frame features a step-up element which consists of a short horizontal bar welded to the seat tube and the main oblique tube of the frame. Not only that this bar can offer some support during mounting, but it can also serve as support for leg stretching, or as a step-up/step-down element for certain spin workouts.

Although it is not as heavy as light-commercial or commercial spin bikes, the PYHIGH S2 still weighs approx. 79 lbs (~35 kg), which is more than twice the weight of the average road bike. This weight delivers an excellent stability. Plus, both the rear and the front base bars are equipped with adjustable stabilizers, concealed by their ABS covers.

Once the unit is assembled, it’s not too difficult to move. The front base incorporates two transport wheels which facilitate its relocation. But nonetheless, the bike’s frame does not fold.

The bike isn’t extremely large. With the frame fully assembled, its length is approx. 41″ (104 cm), while its width is approx. 22″ (55 cm). These being said, the unit requires a usage surface of at least 70″ x 50″ (178 x 127 cm) for safe operation. Also, the highest point of the bike is given by the top of the handlebars when they are set at their highest position, which is approx. 46″ (117 cm) above floor level.

Seat & handlebars

The PYHIGH S2 includes a highly comfortable seat for an indoor cycling bike. It integrates a thick layer of cushioning, its contoured, and has a longitudinal groove to promote breathability during seated workouts. Its upholstery is sweatproof, made of durable vinyl material. It’s definitely a saddle that provides more comfort than the average slim spin seat.

The saddle features a standard attachment system. Therefore, in case you want to replace it, you should be able to find many compatible options for it, in basically any bike shop or online.

The seat offers 4-way adjustability (up, down, forward, backward). Its upright post offers 4.5″ of adjustment (~12 cm), from 33″ (83.8 cm) between it and the lowest pedal to 37.6″ (95.5 cm). Also, its horizontal slider provides several inches of front-to-back travel. This being said, the bike can accommodate users between 5’2″ and 6’4″ (157 – 193 cm) promoting a correct leg extension.

The bike’s handlebar offers the possibility to adopt multiple grips including standard, aero, parallel, or race. It has a loop aero bar which you can use for a close grip, or to which you can attach a tablet holder. The exercise meter also attaches to it. The side handlebars feature a layer of rubber-foam material in order to provide a comfortable grip.

The bike’s handlebars do not integrate pulse sensors, such as the Efitment IC031 for example. Also, its meter does not have a pulse reading function. Therefore, if you need to keep an eye on your heart rate during your workouts, you will have to use a separate device.

Drive & resistance

As we’ve mentioned above, the PYHIGH S2 is lighter in capacity than the S7 model. Therefore, its flywheel only weighs 28.5 lbs (13 kg). But nonetheless, it’s still a perimeter-weighted flywheel, designed for a high inertia and a smooth momentum. It’s chrome-plated, while its side covers are made of ABS material, and of the same colors as the rest of the bike.

The flywheel is bi-directional. This means you can pedal in reverse. However, you cannot coast on the bike. Also, when pedaling in reverse, the resistance remains the same, given by the amount of friction generated by its brake pad.

The bike uses a belt transmission system. It’s equipped with a heavy-duty rubber belt concealed by the side ABS guard. There are three main advantages of an exercise bike belt drive. One, it doesn’t need lubrication; two, it generates considerably less vibration than a chain; three, the pedaling motion is almost completely silent.

The bike’s crankset is highly durable, featuring steel crank arms and aluminum alloy pedal. Needless to say, it’s designed for pedaling while standing up, being able to support any spin workout if the user does not exceed the specified 275 lbs (125 kg) weight limit.

The pedals are equipped with toe cages, so you can secure your feet in place and also add some thrusting to your pedaling. They do not have clips for spin shoes, but their threads are standard 9/16. Therefore, compatible replacements are widely available.

The PYHIGH S2 indoor cycling trainer features a standard friction resistance system, which consists of a felt pad attached under the main bar of the frame. This brake pad is connected to the tension dial on top of the frame, and comes in contact with the bike’s flywheel in a top-down manner. As you turn the knob clockwise, the pad applies more friction to the flywheel, thus, increasing the pedaling difficulty.

There are no pre-determined tension settings on the resistance knob. You simply tighten it until the brake provides the satisfying tension. Also, the tension knob works as an emergency brake. You can press it down to immediately stop the flywheel from spinning.

Exercise meter

The PYHIGH S2 includes a basic fitness meter. It features an LCD display which tracks time, distance, speed, and calories burned. The speed and distance are only shown in metric units (km and km/h). There are no MPH or mile settings for it. Also, as we’ve mentioned above, the meter does not have a pulse reading function.

The exercise meter unit is very easy to operate. It only has one button which toggles On/Off the Scan Mode of the unit. With the Scan Mode set ON, all the values are rotated, each one appearing on the display for a few seconds. You can toggle the Scan Mode off, though, and select one of the values to be shown all the time on the display. Also, the button can serve as a reset for the unit. You can press it and hold it for a few seconds to clear all the values on the meter to zero.

The meter unit requires two AAA batteries. It also has a sleep mode to which will enter after a few minutes of inactivity on the bike. It starts up once more when you begin pedaling or when you press the button.

Assembly & Maintenance

The main body of the frame with the flywheel, crankset, belt, and resistance elements are already assembled. Therefore, you only need to attach the bike’s base bars, the post of the seat and handlebars, the saddle, the handlebar, the pedals, and the meter. This shouldn’t take more than 20-30 minutes. All the tools needed for it are included. Also, the manual provides very clear assembly instructions and schematics.

For maintenance, it’s recommended to periodically inspect the bike for loose bolts and parts. The brake pad may require a bit of lubrication in case it emits a squeaking sound when in contact with the flywheel. For this, a bit of silicone lubricant is recommended. Other than this, it’s a good idea to wipe off the sweat from the frame after each workout.

  1. My bike makes a loud noise when I’m pedaling and the bikes only 4 months old and the noise comes and goes as the bike sees fit. I tried pedaling backwards and still same results. The sound seems to be coming from the drive or drive belt area. Does this bike require any lubrication anywhere on it?

    1. A bike belt drive doesn’t need lubrication. If the noise comes from the drivetrain, the belt may have become a bit loose, so it may need re-adjusting.

    1. Probably, but you’ll most likely need to do some improvising as well if you’re going to install a new performance monitor. Also, the bike doesn’t have pulse sensors installed, so for a function like pulse reading to work, you’ll need a telemetric monitor and a wireless HR chest strap.
