Frame construction

The Titan Fitness air bike features a heavy-duty frame similar to other commercial-grade air bikes. It combines rectangular, oval, and cylindrical tubes in its construction for improved sturdiness and aesthetics. All the tubes in the main frame and the metallic casing of the flywheel are double-coated with a corrosion-resistant and chip-resistant paint finish. The color used is black, this being the only color available for this bike, at least for the moment. The only exception is the seat post which has a chrome finish.

The bike is a bit bulky compared with other stationary bikes. It is approx. 50.25″ (128 cm) long, and 20.37″ (52 cm) wide, while its handlebars reach approx. 50″ (127 cm) above the floor. It is also recommended to leave at least two feet of clearance all around the bike, for ease of access and correct usage.

The bike is pretty heavy as well. Its net weight is 111 lbs (50 kg). This being said, the packaged unit may require two people or at least a box trolley. However, once it is assembled, it can easily be moved by only one person as its front base integrates two large transport wheels. It also has a small handle at the rear which allows a proper grip for an easy lifting for relocation.

The bike’s base bars are equipped with adjustable levelers. Thus, you can perfectly stabilize it on any type of floor. Also, the bike has a low center of gravity and it’s pretty heavy, so you can be sure it won’t rock or move even if you engage in a high-intensity cardio workout.

Seat and handlebars

The Titan Fitness 402604 air resistance exercise bike is equipped with a saddle designed for superior comfort. Its inner shell is made from tough nylon material. It integrates a thick layer of foam padding and its cover is made of durable and easy to maintain vinyl. It is also contoured with a median cutout for improved breathability.

The saddle features a standard collar-type attachment system. Therefore, if you will ever need to replace it, compatible options are widely available. You should be able to find a seat that fits this bike in basically any bike shop.

The bike’s seat is four-way adjustable. Its upright post offers 11 adjustment positions while its horizontal slider adds several inches of front-to-back adjustment. Thus, the bike should be able to accommodate users between 5’0″ and 6’5″ (153 – 196 cm) with no problem. Also, as we’ve mentioned above, it is rated for a maximum user weight limit of 330 lbs (150 kg).

Like most other air resistance exercise bikes, the Titan 402604 is equipped with two moving arms instead of a conventional bike handlebar. The two arms feature short grips with urethane sleeves for improved contact. They do not have sensors or other controls.

The bike’s handlebars are connected to the pedals via two steel bars. This being said, they move for as long as you pedal; you cannot lock them to remain stationary. They have two small pegs for resting your feet on them, in case you want to exercise only by using the handlebars. Evidently, if you use only the handlebars, the pedals will also spin for as long as you move the handlebars.

Resistance and drive

The Titan Fitness 402604 is an air resistance exercise bike. This being said, the main resistance generator is the large fan visible at the front of the bike guarded by the metal casing. The fan is connected to the bike’s pulley, so when you pedal or when you move the arms it spins and generates resistance.

The bike’s resistance is completely user-generated. You don’t need an adapter or an external power source for it. It also does not have an additional magnetic resistance mechanism or a resistance band mechanism to increase or decrease the overall resistance.

Similar to other fitness machines equipped with an air resistance system, the Titan 402604 delivers a dynamic response during usage. In other words, the resistance depends on how fast you pedal or move the arms; the faster you pedal, the more resistance you will get.

The bike features a chain drive system. It uses two chains, a short one and a long one. There are also two pulleys concealed by the drivetrain guard. One is part of the bike’s main crankset connected to the pedals, the other is intermediary. The short chain connects the main pulley to the intermediary pulley, while the long chain connects the fan to the intermediary pulley. This dual chain drive system not only improves motion stability, it also adds extra resistance to the pedaling motion.

The bike is equipped with a heavy-duty set of pedals. They have thick steel arms similar to road bikes. The pedals are also made of metallic alloy and painted black. They do not have toe cages of clips for spin shoes. However, they do have 9/16 threads so compatible options are widely available. They’re also durable enough to support standing up pedaling sessions.

Fitness monitor

The Titan Fitness 402604 air bike is equipped with a fitness monitor that offers a similar set of functions and programs as the Stamina X air bike, although it has a different design. It features an LCD display (without backlight) that tracks time, speed, distance, watts, RPM, calories, and pulse. Speed and distance are by default set to English units (MPH and miles) but you can also set them to metric units (km/h and kilometers). The pulse reading function requires a wireless heart rate chest strap which is not included.

The monitor unit does not have online connectivity and it is not compatible with any fitness apps. However, it has several programs. To begin with, it has three interval programs. These are Interval 20-10, Interval 10-20, and Interval Custom. The two pre-set interval programs have a series of 8 high-intensity workout intervals of 20 sec. work / 10 sec. rest and 10 sec. work / 20 sec. rest. The Custom Interval program allows you to set up the rest and work intervals, as well as the length of the program.

Time, distance, calories, and heart rate target programs are available as well. If a target is selected for time, distance, or calories, the monitor unit will count down from the selected value until it reaches zero. The heart rate interval programs have pre-set targets for 65% HR, 80% HR, and there is also a custom HR setting so you can set your desired % HR. Evidently, the heart rate program requires you to wear a wireless HR chest strap.

Each program has its own quick selection key on the fitness monitor. There also are Start and Strop buttons, an Enter button for selection, and + / – buttons for increasing or decreasing values when customizing a program.

The monitor unit operates on four AA batteries which are included. It starts up when you press Start or when you begin pedaling. It automatically turns off if it does not detect any activity on the bike for several minutes. It also integrates a device holder which consists of a small shelf above the LCD display for keeping your phone at hand when using the bike.

Assembly and Maintenance

The main body of the bike comes pre-assembled. The fan and the other elements of the drive system are already attached as well. However, the rest of the parts do require user assembly. You will have to attach the two base bars, the transport wheels, the pedals, the seat post, the saddle, the two moving arms, the supporting bar of the fitness monitor, and the fitness monitor. This may take more than an hour of your time, but the task is far from being complicated. Plus, the manual provides clear step-by-step assembly instructions and all the necessary tools are included.

Since the bike has a chain drive system, its chains should be lubricated periodically so they don’t catch rust. But since it’s a bike made for indoor use, the chains should not need to be lubricated as often as for a road bike. The arms joints and other moving parts may also need lubrication from time to time. Other than this, you should also keep the bike clean and periodically check for loose bolts and parts.
