The ONETWOFIT OT198 is one of the indoor cycling bikes released in 2020. It’s an exercise bike made for home use featuring a closed flywheel similar to the YESOUL M1. However, it has a slightly different construction and lacks the Bluetooth connectivity. It does come with a basic fitness monitor, though.

Frame construction

The ONETWOFIT OT198 features a triangular frame made of steel tubing. It combines oval and rectangular tubes in its construction for improved sturdiness and aesthetics. The frame tubes are precision-welded and coated with a corrosion-resistant paint finish. The color used is black, with the “ONETWOFIT” logo painted white, these being the only colors available for this bike, at least for the moment.

The seat tube, the handlebar tube, and the flywheel are chrome-plated. The flywheel and the drive-train feature large covers made from a durable ABS polymer. The bike also integrates several other ABS small parts, such as the base bar caps, the adjustment knob caps, the tablet holder, and the fitness monitor.

The bike is not too large. With all the parts assembled, it is approx. 38.19″ (97 cm) long, and 21″ (53 cm) wide, while its highest point reaches approx. 43.3″ (110 cm) above the floor. Some extra usage area should be left all around the bike for easy access. In most cases, the recommended clearance is two feet all around the unit.

The bike is not too heavy either. It weighs around 60 lbs (27 kg) which pretty much means that it can be carried and assembled by only one person. Also, once it is assembled, it is even easier to move as its front base is equipped with transport wheels.

Seat and handlebars

The ONETWOFIT OT198 indoor cycling bike is equipped with a large saddle made for superior comfort. Its top section integrates a thick layer of polyurethane foam padding with a durable vinyl cover. It is contoured with a large cutout in the middle for extra breathability. It’s also important to mention that its attachment system to the adjustment element is collar-type. This allows you to easily remove it if necessary, and compatible replacements are widely available.

The bike’s seat is four-way adjustable (front, back, up, down). Its upright post offers approx. 5″ (12 cm) of adjustment, from 33.4″ (85 cm), to 38.1″ (97 cm). The horizontal slider adds several inches of front to back adjustment. Therefore, the bike should be able to accommodate users between 4’8″ and 6’2″ (147 – 188 cm), allowing a complete leg extension. It is also pretty durable, the rate for a maximum user weight limit of 265 lbs (120 kg).

The bike’s handlebar is only two-way adjustable (up, down). It does not have the front-to-back slider like the seat. It offers an adjustment span of approx. 3″ (8 cm), from 40.1″ (102) above the floor, to 43.3″ (110 cm).

The handlebar features a multi-grip design. It offers the possibility to adopt an off-road grip, a climbing grip, and a standard grip. It has a small loop bar in the middle that allows a close grip if you don’t install the device holder. The longer side grips have PVC foam sleeves for improved contact. However, they do not have pulse sensors like it is the case for other indoor cycling bikes, such as the Sunny Health & Fitness SF-B1852, or the Soozier A90-144.

Resistance system

The ONETWOFIT OT198 exercise bike is equipped with a friction resistance system. It is not a motorized bike, so the resistance adjustments are done manually. This also means you don’t need a power adapter or power cord for it.

The bike’s resistance system consists of a felt pad attached to the bike’s frame above the flywheel and to the tension knob above the main frame tube. It is also concealed by a large plastic guard to prevent damage. However, this guard can easily be removed. When you adjust the resistance, the pad applies more or less friction to the flywheel. For example, if you turn it clockwise, you will tighten it on the flywheel and the pedaling difficulty will increase.

The bike’s tension knob does not have pre-determined resistance settings on it. You can basically tighten it onto the flywheel up to a point when you can barely pedal. The brake pad will eventually wear out and will need replacement. However, even if you will be using this bike for a few hours a day, it should still take more than a year for it to completely wear out.

The tension knob also has the function of an emergency brake. You can press it down to stop the flywheel instantly. This feature is actually necessary for most spin bikes as their flywheels are usually heavy, and trying to stop them with your feet from the pedals may result in injuries.

Drive system

The ONETWOFIT OT198 indoor cycle integrates a 26 lbs (11.7 kg) flywheel which is completely concealed by a large, circular ABS plastic guard which considerably improves the bike’s safety. The flywheel is perimeter-weighted. This design adds stability to the ride and improves momentum.

The flywheel is bi-directional. In other words, the bike permits pedaling in reverse. This can be a plus, as you can always diversify your workouts, alternating regular with reverse pedaling. However, coasting is not possible and when pedaling in reverse, the resistance remains the same as when pedaling forward.

The bike is equipped with a pretty sturdy crankset. The crank arms are fairly short, so in order to compensate you will have to set the seat higher if you have a longer inseam. They are steel-made and the pedals are made from an aluminum alloy. The whole crankset with the pedals is pretty durable so you should be able to stand up while pedaling. This is, after all, a bike made for spin workouts.

The pedals have toe cages with an adjustable strap in case you need to secure your feet on them. They do not have SPD elements for spin shoes, but their threads are standard (9/16) so you can replace them whenever you want. Compatible pedals are widely available.

The bike is equipped with a belt drive system. It integrates a poly-v belt highly resistant to abrasion and stretching. The belt is fully covered by a large guard for improved safety. Since it’s a belt and not a chain, it does not require periodic lubrication.

Fitness monitor

The ONETWOFIT OT198 indoor cycling trainer is equipped with a basic fitness monitor similar to the one included with the Lanos bike. It features an LCD display that tracks time, speed, distance, and calories burned. It also has an odometer function.

The speed and distance values are shown in metric units (kmh and kilometers). They cannot be set to imperial units (mph and miles). Also, the unit does not have a pulse reading function. The bike has no pulse sensors and you cannot sync it with a wireless HR chest strap like an ANT+ or Polar.

The monitor unit is very easy to use. It has only one button. By pressing it multiple times, you can scroll through the workout metrics and select the one you want to view. This way, you can also select its Scan Mode which rotates all the metrics showing each one for a few seconds, then moving to the next. The button also covers the unit’s reset function. By holding it down for a few seconds all the values are cleared to zero, except the odometer.

The monitor unit is battery-powered. It requires two AAA batteries. It begins recording your workout data when you begin pedaling. It also automatically turns off if it does not detect any activity on the bike for more than four minutes.

Assembly and Maintenance

The bike’s main body comes pre-assembled. You only need to attach the two base bars, the seat, the handlebars, the pedals, and the fitness monitor. This shouldn’t take more than 30 minutes of your time. A basic toolkit is included and the manual provides pretty clear assembly instructions.

Once the bike is assembled, maintenance doesn’t require much. All you need to do is keep it clean and maybe wipe the sweat that may fall onto the frame at the end of the workout. It is also recommended to periodically inspect the bike to make sure that all the parts still function properly and all the bolts still hold tight in their places.
