The ONETWOFIT OT319 is one of the indoor cycling bikes released in 2021. As opposed to the OT198 model that we’ve already covered here, it has a heavier flywheel and a greater user weight limit but lacks the large flywheel cover. It also includes a set of elbow rests which are a nice touch.

The ONETWOFIT OT319 indoor cycle features a durable steel frame with a design similar to the Murtisol bike. It’s constructed on a triangular steel frame with the main tube slightly curved for improved sturdiness and aesthetics. Most of the tubes in its construction are oval; the only exceptions are the handlebar tubes which are cylindrical and the seat slider which is rectangular.
It’s also important to mention here that the seat tube intersects with the main curved tube and it’s welded to the base tube. This considerably improves the overall structural sturdiness of the bike.
All the steel tubes in the frame are double-coated with a black paint finish. The only exceptions are the flywheel, the seat tube, and the handlebar tube which are chrome plated. The drive belt cover, the side covers of the flywheel, and the casing of the fitness monitor are made from ABS plastic.
Similar to most other spin bikes, the ONETWOFIT OT319 is not a large fitness machine. It is approx. 42.5″ (108 cm) long, and 20.9″ (53 cm) wide with all the parts assembled. This being said, it can fit pretty well even into a small room. However, it still is recommended to leave at least two feet of clearance all around it.
The bike is fairly heavy. Its net weight is approx. 98 lbs (44 kg). Therefore, the transport of the packaged unit may require two persons. However, once the bike is assembled, it can be moved with ease by only one person as its front stabilizer features two transport wheels. Also, both base stabilizers have adjustable levelers.
Seat and handlebars
The ONETWOFIT OT319 exercise bike is equipped with a pretty decent saddle. Its top is made from a high-density foam material (EVA or urethane). It is contoured, in order to provide superior breathability. It is also flexible and has a collar-type attachment system, so it can easily be removed and replaced if necessary.
The bike’s seat is four-way adjustable (up, down, front, back). Its upright post offers approx. 6.2″ (16 cm) of adjustment, from 31.9″ (81 cm) above the floor level, to 38.19″ (97 cm). The top slider also adds several inches for horizontal adjustment. This being said, the bike should be able to accommodate users between 5’2″ and 6’5″ (157 – 196 cm). It is also rated for a maximum user weight limit of 330 lbs (150 kg) which is quite impressive for a home-use spin bike.
Unlike the seat, the bike’s handlebar assembly is only two-way adjustable (up, down). It does not have the horizontal slider feature. It offers approx. 4″ (10 cm) of adjustment, from 39.9″ (101 cm) above the floor, to 43.9″ (111.5 cm).
The handlebar assembly features a multi-grip design. It offers the possibility to adopt a climbing grip, a close grip, an off-road grip, and a standard grip. It comes with a set of elbow rests so you can also adopt an aero grip. Its side grips have a layer of PVC foam for superior contact. However, they do not integrate pulse sensors and the fitness monitor does not have a pulse reading function.
Similar to the FBSport bike that we’ve already covered here, the ONETWOFIT OT319 is equipped with a standard manual friction resistance system. This being said, you don’t need a power cord or a power adapter for it. The only power source required is a set of batteries for the fitness monitor.
The resistance system consists of a felt pad attached under the main frame tube above the flywheel. The pad is connected to the bike’s tension knob, so when you turn this knob clockwise, it applies more friction to the flywheel.
The bike’s resistance system does not have pre-determined levels or “clicks” like most magnetic exercise bikes have. You simply tighten the brake on the flywheel until you get a comfortable difficulty. As a general idea, the pad can be tightened on the flywheel up to the point you can barely pedal.
The bike’s tension knob also has the function of an emergency brake. You can press it down to stop the flywheel from spinning. This is actually necessary especially if you’ve been pedaling at a high speed, as the flywheel is very heavy, and stopping it with your feet from the pedals may cause injuries.
One last aspect to mention here regards brake maintenance and replacement. Although the felt pad is pretty durable and should last for at least a year even if the bike is used daily, it will eventually wear out and require replacement. Also, adding a few drops of silicone lubricant on the edge of the flywheel can improve the smoothness of the ride.
The ONETWOFIT OT319 indoor cycle is equipped with an extra-heavy flywheel. It weighs 44 lbs (20 kg), which is usually the flywheel weight of a club-level spin bike. It is also perimeter-weighted for superior inertia and for a consistent pedaling motion.
The flywheel is bi-directional. This means you can pedal in reverse if you want. Coasting is not possible, though, and when pedaling in reverse, the pedaling motion has the same resistance as when you pedal forward. Thus, you can alternate forward pedaling sessions with reverse pedaling sessions to focus different muscle groups.
The bike is equipped with a belt drive system. It uses a poly-v belt highly resistant to stretching and abrasion. It does not require periodic lubrication like a chain drive which is a plus. It also generates slightly less vibration than a chain drive, which is reflected in the overall smoothness of the ride.
The bike features a heavy-duty crankset. The crank arms are steel-made, similar to the ones in road bikes. They’re pretty long, so the bike promotes ample movement. The Q-Factor (spacing between the pedals) is also narrow (under 180mm), so the pedaling motion does not generate extra lateral stress on the user’s joints.
Last but not least, the included pedals are made of aluminum alloy. They do not have SPD clips for spin shoes but do have toe cages in case you need to secure your feet on them, or perform workouts with extra thrust. They have 9/16″ threads, so in case you will ever need or want to replace them, compatible options should be available in any bike shop.
The exercise monitor included with the ONETWOFIT OT319 bike is a pretty basic model. It does not have target settings, pre-set programs, or online connectivity. It features an LCD display (without LED backlight) which tracks time, speed, distance, and calories burned.
The monitor unit does not have an odometer function and does not track pulse. It is not telemetric and you cannot sync it with a wireless heart rate chest strap. Thus, if you need to keep an eye on your pulse during your spin workouts, you will need to use a different device.
The fitness monitor has only one buttons (MODE) and it’s very easy to use. You can press the button repeatedly to select between time, distance, speed, and calories burned. This way, you can also select the Scan Mode which automatically rotates all the metrics, showing each one for a few seconds. The button also covers the reset function of the unit. You can press it down and hold it for a few seconds to clear all the values on it to zero.
As we’ve mentioned above, the monitor unit is battery-powered. It requires a set of AA batteries which are not included. It starts up when you begin pedaling, and also automatically turns off if it does not detect flywheel movement for more than four minutes.
Assembly and Maintenance
The most important parts of the bike, such as the flywheel, the crankset, the belt, and the brake come pre-installed, attached to the frame. However, the rest of the parts do require user assembly. You will have to connect the two base pieces to the main frame, the seat, the pedals, the handlebar, and the fitness monitor. This shouldn’t take more than 30-40 minutes, though. A basic toolkit is also included.
For maintenance, it is recommended to keep the bike clean. The brake pad may require lubrication from time to time, and when it’s used up, replacement. Other than that, it is also recommended to periodically inspect the bike, to make sure that all the parts still function correctly.
