The XTERRA Fitness AIR650 Airbike Pro is a heavy-duty exercise bike designed directly for athletes to rehab patients and everyone in between. The XTERRA AIR650 AirBike Pro reinvents and retools nearly every component of the traditional fan bike, from the frame construction to the crank, pedals, monitor, and more.
The great thing about the AIR650 Airbike Pro is that it can work for a beginner, a rehabbing athlete, or a seasoned pro training at the highest levels of competition—no matter their sport, body type, or ambition. While fan bikes have existed for nearly half a century, modern advances in their design and function have made them increasingly in demand.
The XTERRA Fitness AIR650 comes with everything you’re accustomed to and more! The fitness monitor measures distance, watts, speed, and calories. It’s everything you need in one easy-to-read console with the ability to set up Interval Training, Target Training, Heart-Rate Training, and more.
With the XTERRA Fitness AIR650 Airbike Pro, the user controls the resistance, not the machine. As a result, you can control the intensity of your workout – The harder you push, pull, and pedal, the more air you’re moving, and the higher the resistance.

AIR650 Frame Construction
The XTERRA Fitness AIR650 Airbike Pro features a heavy-duty steel frame coated with a corrosion-resistant and abrasion-resistant powder finish. The paint color is white for the mainframe, black for the base bars, and the seat post features a chrome finish.
Even though it’s an air bike and not a spin bike, the XTERRA AIR650 is considerably heavy. The frame, fully set up, weighs approximately 115 lbs (52 kg), which is three times the weight of your average road bike. Thus, the cycle has no stability issues; it won’t rock or wobble even if you exercise at the highest speeds. Plus, it supports users up to 350 lbs (159 kg).
The bike has adjustable levelers on all its base bars in terms of stability. In addition, they have rubberized pads for superior adherence. The front base integrates two transport wheels, allowing you to relocate it quickly.
The fully assembled bike is not extremely large compared to other fitness equipment. It is approx. 48″ (122 cm) long and 28″ (71 cm) wide, while the top of its handlebars reaches approx. 54.5″ (138 cm) above floor level. It is advisable to leave at least two feet all around it to ease access and safe usage.
Last but not least, this XTERRA exercise bike integrates two footrests. Not all air bikes have this feature, and it can be pretty valuable as it allows you to put some diversity into your workouts.
Seat and handlebars
The XTERRA Fitness AIR650 Airbike Pro has a four-way adjustable seat (up, down, front, back). In addition, the vertical post has multiple adjustment positions, approximately—1″ (2.5 cm) apart. Plus, the horizontal slider of the seat provides five extra inches of adjustment.
Therefore, the bike can accommodate users between 5’2″ (157 cm) and 6’7″ (200 cm). It is essential to note that even though the seat offers excellent adjustability, a shorter user may not reach the handgrips too well when seated. However, they can still exercise while standing on the pedals or add an extra set of handgrips.
The bike includes a slim saddle similar to the spin bike seats. It’s not designed for super comfort but does integrate a layer of padding and has a contoured for extra breathability, providing optimal support. In addition, it has a standard attachment system, so compatible options are widely available if you ever want to replace it.
The XTERRA AIR650 Pro features two solid moving arms with a multi-grip design. However, it does not have stationary handlebars. Instead, the arms continue to move for as long as you pedal.
A layer of high-density foam fully covers the bike’s grips to provide superior comfort. Unfortunately, they do not integrate HR pulse sensors. However, the bike’s fitness monitor is telemetrically capable and does have a wireless pulse reading function.
AIR650 Drive and resistance
The XTERRA Fitness AIR650 Airbike Pro has a dual chain drive system and an intermediate pulley. The first chain connects the crank wheel to the intermediate pulley, while the second chain connects the flywheel to the intermediate pulley.
This drive system adds resistance to the pedaling motion and improves the pedaling sensation, which adds smoothness to the ride. Also, a chain drive comes with the advantage of durability. With proper lubrication, the chain can last a lifetime.
The bike’s crankset is exceptionally durable, featuring steel arms and metallic alloy pedals. In addition, the bike has a maximum user weight limit of 350 lbs (159 kg), including the crankset and pedals, so you can pedal while standing up with no problem.
Like other air-resistance bikes, the included pedals do not have spin clips, straps, or toe cages. Instead, they’re painted black and have small, anti-skid lugs for improved foot stability. They also have standard threads.
The bike’s flywheel is the main resistance-generating element. It’s relatively large in diameter (27″ / 68.5 cm) and features nine steel blades for improved resistance. Its casing is also metallic.
This XTERRA exercise bike does not have other resistance elements apart from the flywheel fan. The resistance is purely generated by the fan and improved by the dual pulley system. No magnetic or friction brake exists, so you cannot manually adjust the overall resistance.
But on the other hand, just like any other air resistance bike or rower, it provides a dynamic response. Thus, if you pedal and move the arms faster, you will get more resistance.
The XTERRA Fitness AIR650 Airbike Pro includes a reasonably decent fitness monitor. To begin with, it has a multi-window LCD to show as many workout metrics as possible. It tracks time, total time, distance, calories, speed, RPM, watts, and pulse.
For speed and distance, you can select either Metric or English units. Unfortunately, the bike does not have HR pulse reading sensors, but the monitor is telemetric; it can read your pulse through a wireless HR chest strap. However, this accessory does not come with the bike.
Unfortunately, the monitor does not have online connectivity, nor is it compatible with any fitness apps. However, it has seven programs to keep you motivated. Target Time, Target Distance, Target Calories, Target HR, Interval 20-10, Interval 10-20, and Custom Interval. Each one has a quick-access button on the unit.
The Target Time, Distance, and Calories programs allow you to select goal values for these metrics. The unit will show the remaining amount until you reach your workout goal when setting goal.
You can select between 65%, 85%, and maximum Heart Rate for target HR. After choosing the HR goal, the program initiates, and the monitor will prompt you to increase or decrease your workout intensity depending on your current heart rate.
The fitness monitor also makes available three interval workouts. These are 20-10 Intervals, 10-20 intervals, and Custom Intervals.
For the 20-10 Interval, you will have to pedal at high intensity for 20 seconds, then rest for 10 seconds. The 10-20 Interval is the same, with 10 seconds of work and 20 seconds of rest.
And finally, for the Custom Interval, you can select the desired duration for the work and rest intervals.
The fitness monitor is battery-powered, and it requires 4 AA batteries. However, the batteries do not come with the bike. It also has a sleep mode that initiates after 60 seconds of bike activity. After that, you can either pedal or press the Start button to wake it up.
AIR650 Assembly and Maintenance
The main body of the bike comes pre-assembled. You only have to add the base bars, the monitor bar, the two moving arms, the seat, the pedals, and the fitness monitor.
Consequently, it shouldn’t take more than one hour of your time. An essential toolkit comes with the bike, and the provided manual provides step-by-step assembly instructions.
Since the bike has a chain transmission, lubrication is required. However, besides this, you only have to keep it clean and periodically check for loose parts and retighten or replace them as needed.
