A fan based low inertia cycling trainer. Take your indoor cycle training to the next level!
Of Revbox’s many characteristics, what are it’s most unique features?
The fan, which forms the heart of the trainer, operates almost entirely without centrifugal mass, giving the Revbox its very low inertia. This means that the athlete does not at any point in the 360° pedal stroke receive any assistance from the weight of the flywheel, as is the case with most other trainers.
This has the major advantage that all leg muscles are utilised through the entire pedal stroke. Low inertia training can best be described as riding uphill, or against the wind, where high inertia training can be compared to riding downhill or with the wind at your back.
The entire pedal stroke becomes audible through the sound of the fan, enabling the athlete to achieve an even and smooth pedalling motion. If the athlete succeeds in generating a sound from the Revbox that is even and constant throughout the pedal stroke, they can be sure that they are training all muscles equally. This is an invaluable advantage that no other trainer on the market can rival.

The REVBOX Concept
The Revbox Erg supersedes existing stationary trainers by providing athletes with a high performance training tool that has an unlimited resistance range in a compact transportable layout. Design requirements were to create a device that would allow extremely high power output training, from very low to very high cadences, suitable for even the most powerful elite athletes.
Just replicating general road conditions was too broad an objective. Our real goal with the Revbox Erg was a training unit that would stimulate specific muscular, aerobic, and anaerobic adaptations to improve key areas of a cyclist’s performance. The Revbox Erg uses the chain of the bicycle to transfer power to the fan for immediate, non-slip resistance.
Designed and engineered in Christchurch, New Zealand, unparalleled targeted performance gains are possible that cannot be achieved with tire-roller based stationary trainers. For cyclists serious about achieving their goals and seeking precise time managed training benefits, the Revbox Erg is the ultimate high performance training unit.
If required the large 580mm diameter fan produces air drag that allows training at power outputs in excess of 2000 watts. In a 53/11 gear ratio, just 50 pedal revolutions per minute, requires an output of 500 watts, making the Revbox Erg an ideal training unit for low cadence strength training. At the top end, 90 RPM in a 53/11 ratio requires 1800 watts and at the low end peddaling with 90 RPM in a 39/28 ratio requires less than 130 watts, which demonstrates the versatility, and resistance range of the Revbox Erg design.
The format of a low friction mechanical connection to the bike via the chain, and the high revolutions of the fan, creates an inertia rate unlike that of any stationary device, and perfect for the specific high power output training demands of the ambitious athlete.
Standard trainer designs have a usable resistance range defined by the mechanical limits of the small diameter units, and exhibit linear resistance increases. An extremely large diameter fan, however, displaces a huge air volume and provides exponential resistance for training across a broad range of parameters. This is a significant part of what makes the Revbox Erg such a brilliant training tool.
The resistance scale provided by the Revbox Erg is suitable for amateur riders through to Tour de France athletes and Olympic track sprinters.
Next to monitoring, and training to, specific power outputs, understanding inertia rates are a critical aspect to improving performance on the bike. A stationary trainer with high inertia only replicates riding on the flat on a smooth road with calm conditions or a tail wind. The Revbox Erg with its deliberately tuned low inertia lightweight air-braked fan encourages increased muscle and motor-skill development at high cadences, as well as providing a very effective means of constant resistance for strength training at low cadences. Developing neuromuscular efficiency, essentially brain to muscle coordination, at high intensities, is crucial to a rider improving the efficiency of oxygen utilization by the working body.
Inertia rates of a stationary trainer have a significant impact on a rider’s pedaling dynamics. Training at carefully chosen pedal speeds and power outputs, certain muscle recruitment is targeted, and results in effective coordination and physiological efficiency gains. The Revbox Erg’s low friction chain connection to the bicycle, enhance the specific inertia characteristics, which make for very stable dynamics at high intensity pedaling loads. This means the resistance unit will not gather momentum at high cadences, nor will it stall at low cadences. This is an ideal environment for the athlete to target exact physiological responses.
Years of research, design, and prototypes have led us to create the most versatile high performance stationary trainer in the world. No other unit can claim to have such a wide resistance range, such specific training benefits, and be so easily transportable. The first priority was the resistance, which had to be suitable for the most powerful riders. To have no compromises we concluded the Revbox Erg must be made with a large diameter air-braked fan unit.
Next, our designers considered the biomechanics of cycling at various power outputs and cadences. A stationary trainer that would be designed for specific high intensity training at pedal speeds from 50 - 250 RPM and power outputs up to 2000 watts would only work effectively within a narrow band of resistance inertia.
A unit that could provide high resistance with a specially tuned low inertia rate had far reaching performance enhancing implications, especially for improving the neuromuscular efficiency of a cyclist. Creating a low friction mechanical interface with the bicycle and eliminating the traditional tire-roller connection was a key step in building such an effective training machine. The Revbox Erg is the final result of our work, an advanced training tool for cyclists seeking an edge over the competition.
Once the Revbox Erg design had met the resistance requirements we looked at optimising the size and weight. It has been made to be compact, easily packaged, and made of the highest quality materials. The side panels are the main structural component of the device and result in a very low side profile to minimise the overall volume. These rigid side panels along with the aluminium plate cover around the outer circumference make for a durable unit that will withstand even rough travel conditions. The stabiliser legs are removable without tools, in seconds, and the whole unit packs quickly in an optional reinforced, padded travel bag.
The fan unit is made of a specially machined hub that holds nine aluminium fan blades. The dimensions of the blades have been carefully designed to promote a resistance range that allows incredibly high power output training at even very low pedal speeds. A cadence 45 RPM in a 53/11 gear ratio requires a huge 500 watts.
Materials used for the Revbox Erg are injected moulded ABS for the side panels, aluminium along with stainless steel for all other parts. No paint or coatings are required. Every single part is available as a replacement in case damage should occur. Compatibility is for road bikes for 130/131mm rear wheel spacing and 10 and 11 speed cassettes provide a further adjustable means of resistance increments. Indexing compatibility for 10 or 11 speed drivetrains from Shimano, Sram and Campagnolo is possible.
The Revbox Erg is a valuable asset when a rider cannot train where they intend to perform. For example when preparing for London Track events it would be most beneficial to train on that track, or when focused on the Giro d'Italia, to ride the Passo del Gavia. If financial reasons, logistics, or the need to race where the competition currently is, makes this not possible, the athlete can use the Revbox Erg to prepare for the fitness requirements of the goal events.
In a situation where the race environment is not ideal, like in Beijing 2008 preparing for the Olympic road race where smog was an issue, the Revbox Erg can be easily and cost effectively transported to inside venues and used to train at specific power outputs targeted for the event. For track cycling competitions where often equipment needs packing up on a daily basis, the Revbox Erg is easily disassembled with two quick release levers. With the optional reinforced travel bag the unit can be carried away conveniently by hand.
The travel bag has dimensions 60cm x 750cm x 20cm for a transport volume of just 0.09m3 and a total packaged weight of approx 12.5kg. The unit on its own is just under 9.0kg, lighter than many other trainers, but with a considerably higher resistance range. The Revbox Erg has the best ratio of unit resistance to size and weight of any stationary trainer in the world, making it especially practical and economical for international air transport.
How To Use:
By simply removing the rear wheel, a road bike can be fitted to the Revbox Erg. The quick release skewer on the drive hub is tightened on the bikes dropouts just like a skewer on a wheel. Stabiliser legs are fitted to the unit with attached quick release skewers. No parts need to be removed or adjusted. The Revbox Erg works without a front wheel block as it has been designed to be the same height as a 700c x 23mm road wheel.
Every 10 or 11 speed cassette with Shimano spline can be fitted to the freehub body and the Revbox Erg can take ratios up to 11/29 to allow also beginners to train with very low power put with less than 130 watts if required.
If a rider does not have a power measuring device such as an InfoCrank, P2M or any other power meter, power can get messured with our Revbox Power App, which is available for free from the Google Play store. To use the app a special sensor kit is required.
Superior to monitoring heart rate which is only a measure of how hard the human body is working internally, power output for a cyclist is the amount of work generated into forward motion. Power equals work multiplied by time. Work for a cyclist is the force applied to the crank arm times the cadence. Multiply this by time and we get power. What this means is that power is a definitive value of a cyclist’s performance. Unlike heart rate, there are no variables with power.
Training to specific power outputs usually requires the use of a crank system such as those made by InfoCrank, Power2Max, or a rear wheel based device like a PowerTap hub. Using the Revbox Erg as a training tool, a rider who does not have a crank based system can use the supplied laminated handlebar charts. These align fan speed with power, with the fan speed being picked up by a wireless cycle computer. While not as accurate as a crank based system, this method is an adequate way for a rider without that equipment, to gauge their power while training on the Revbox Erg.
From in depth personal fitness tests, with protocol explained in the supplied Revbox Erg manual, a rider is able to create an athletic profile of their current physiological capacity. This information can be used by the rider to train to certain power outputs, maximising time and efficiency. Just with an additional cadence computer, even a rider without power measuring cranks is able to train very specifically for their goals using the Revbox Erg.
The amount of force that can be applied by the cyclist to the crank arms to create torque is strength. Rotational speed (pedal cadence) multiplied by torque equals power. While power is most often referred to for training purposes, power is essentially the end value of the strength applied times cadence relationship.
To ride faster a cyclist can maintain a certain pedal speed and push a harder gear or pedal the same gear, just faster. Both result in more power but each puts very different demands on the human body. Strength and cadence need to be carefully understood and considered if a cyclist is to achieve maximum benefit from their training and maximum performance while racing. The Revbox Erg has been designed for effective training of both high values of strength and cadence. The chain drive mechanism will tolerate huge amounts of acceleration force for non-slip power transfer. The large diameter air-braked fan is impossible to spin out as the air resistance keeps rising with speed.
Strength training is often performed at low pedal speeds, focusing on taxing the muscular system. The Revbox Ergallows a rider to train at an extremely low cadence range but at very high resistance. In the highest gear of 53/11, just 45RPM requires 500watts, while 60RPM requires 800watts, providing a range difficult enough for even the strongest athletes. The specially tuned low inertia, low friction design of the Revbox Erg means that a rider is able to maintain good pedaling technique which isolates and develops specifically targeted muscle groups.
The counterpart of strength to produce power, developing a high cadence, or pedal speed, is essential for a rider to reduce the onset of fatigue, and also improve acceleration. High cadences, while requiring more oxygen, increase the body's recruitment of slow twitch muscle fibers. These are more efficient at producing energy and have greater fatigue resistance than the higher force producing fast twitch muscle fibers.
The Revbox Erg has a tuned resistance that encourages recruitment of the lower leg muscles through the crankarm “dead-center”. Improving the coordination of these muscles in tandem with the main force producing muscles of the upper legs, is a crucial aspect in a rider elevating their sustainable cadence. The first requirement for achieving a high cadence is coordination. As this neuromuscular functioning is raised to a level relevant to the riders goals, cardiovascular and strength training can also be ramped up accordingly.
To improve a riders functional cadence, training on a low inertia high resistance stationary trainer provides the most controlled and effective environment. The large fan of the Revbox Erg maintains resistance throughout the whole circumference of the pedal stroke. A high inertia trainer unit will accelerate from the point of peak power and maintain momentum through the “dead-center” of the pedal stroke. Much like cycling with a tail wind, this limits specific muscle adaptations as the trainer unit is doing much of the work for the rider during a significant portion of the pedal stroke.
In a sport that requires such rapid and repetitive movements from major muscle groups, coordination, neuromuscular-efficiency, often limits performance more than a lack of strength or cardiovascular fitness.
Neuromuscular efficiency is described as the ability of the brain to muscle pathway to allow prime movers, synergists, stabilisers and neutralisers to work together in synergy as an integrated unit.
Neuromuscular efficiency is crucial to all cyclists at all levels as improving the efficiency of the power delivery to the pedals ultimately results in better oxygen utilization and less muscle fatigue.
The Revbox Erg air-braked fan with precisely tuned low inertia and low friction chain drive connection provides an ideal controlled environment for a rider to concentrate on their technique and intensity.
With coordination being the most important prerequisite for achieving a high cadence, it is easy to see how a rider can use this to increase power output, enhance endurance by decreasing muscle fatigue, and improve acceleration and sprinting. The Revbox Erg air fan provides a brilliant audial recognition of where in the pedal rotation power is being applied by the rider. The diameter of the fan, its weight and rotational speed, have been designed to allow a rider to become aware of inconsistencies in their pedal stroke.By using this feature, a rider can improve their muscle coordination and ultimately produce more power, with less fatigue, for longer durations.
Almost a science in its own right, preparing the human body for peak performance in the minutes prior to an event, is now understood to have even more influence than once thought. For the athlete considering every detail over months or even years of training, a correct and planned warm-up schedule needs to come from an in-depth analysis of the power outputs, cadence range, and momentum rates, applicable to the competition.
Standard trainer designs and especially the “rollers” styles are often not able to provide enough resistance for a rider to replicate certain heart rates or power outputs at cadences appropriate for the event. Rollers in particular are not able to generate anywhere near the required resistance levels, so even though the heart rate of an individual may be raised to the target zone, resistance for the muscles is not.
The Revbox Erg with its capacity to provide unlimited resistance in a tuned low inertia format, means any bike rider from amateur road cyclist to world champion track sprinter, can prepare both cardiovascular and muscular systems as best as possible. Events where the conditions will mean the rider carries a low level of momentum such as hill climbs, or flat road head wind, and of course mountain biking, need to have special consideration given to the warm up. High inertia trainers are not able to replicate these loads. The Revbox Erg is a perfect warming up tool for any athlete serious about maximum performance.
To get the most out of your training we recommend our Revbox Power App along with our required sensor set or a crank based power meter to monitor your training.
Although events are often held in environments that may be affected by weather, training however is most often best done in controlled situations to make the time spent exercising as effective as possible. Many cyclists will have experienced finishing a training ride realising that a large proportion of time has not been spent within the required intensity zones. If an athlete can make small improvements in every training session, then the accumulated benefit over weeks, months or years, can add up to significant performance gains.
Attempting to perform high intensity, specific training sessions outdoors, does not come close to the consistency of a stationary indoor environment on a Revbox Erg. The duration of training inhibited due to road surface variations, corners, and traffic, as well as hill gradient variations, wind, rain, and mechanical issues such as flat tires, all add up to a considerable loss that could potentially have been fitness gains if a rider focused important training sessions on a Revbox Erg.

The Power Process:
To begin to understand the process of forces that produces power, we must consider the laws of physics and how these apply to the bicycle rider. While cadence multiplied by strength equals power, cadence and strength themselves have limits dictated by the riders cardiovascular capacity and efficiency of movement, or coordination.
Power = Work x Time
In basic terms this means a cyclist moves forward by pushing on the pedals for a given time period. (Technically if a rider pushes on the pedals but the bike is prevented from moving forward, and therefore the crankarms do not move, then the rider has produced a force but not work).
Breaking this equation down, if we look at what makes up Work we get:
Work = Force x Distance
This means as a rider applies Force (from muscle strength) times Distance (rotation of the crankarms) we get a measure of Work. More Force requires more strength. To produce Power then, a rider applies Force (the leg strength) over a Distance (the crank revolution) to create Work for a period of Time.
Force = Inertial Mass x Acceleration
(Inertial Mass is the pushing leg and Acceleration is the legs tendency to begin to rotate the crankarm)
Torque = Rotation x Force
Torque is the tendency of a Force to rotate an object about an axis. What this means is that Torque = Force (muscle strength) x Length of lever arm (crankarm in the case of a bicycle).
Power Output = Torque
(Force applied to a crankarm by strength of riders leg) x Rotational Speed (frequency of the applied Torque, high RPM/lower Torque =low RPM/higher Torque) x Time
Power = ((Mass x Acceleration) x Distance) x Time
An endurance rider must be able to maintain a low percentage of their max force to utilise slow twitch muscle fibers to minimise fatigue during the event. If a rider does not have sufficient aerobic capacity or cannot develop sufficient aerobic capacity to main a high cadence (therefore low percentage of max force) then the rider must gain more muscular strength to be able to perform at the required power output. A rider should create a fitness profile of different aspects and limits of their physiological capacity to be able to improve their performance in desired areas as effectively and efficiently as possible. Just performing a standard V02 Max test does not provide in depth enough and adequate enough information to write a training program to result in maximum power output gains.
Inertia is the resistance of any object to a change in its state of motion or rest. This is important because the rotational inertia of a stationary trainer resistance unit has a significant influence on a riders power application and pedaling coordination.
High inertia trainers use heavy rotating units and generally replicate riding on a flat road at low to mid power outputs. They can struggle however, to provide enough resistance at high power outputs. A high inertia trainer only requires force to be applied on the down stroke of the pedal cycle, limiting muscular training benefit. Once the heavy fan or flyweight builds up momentum, the rider has then “topped-out” the trainer, where an increase in pedal speed in the hardest gear does not have any significant effect on resistance.
Virtually any tire-roller type trainer is a low inertia/high friction device. Manufacturers attempt to overcome the friction and add resistance with flyweights. At low pedal speeds the high friction causes a stalling effect through the pedal stroke “dead-center” which forces the rider to employ a compensatory pedaling technique.
The Revbox Erg with huge diameter fan relies solely on air as resistance and will increase exponentially, making it impossible to “top-out”. The fan is very lightweight, minimising rotational inertia for maximum muscle activation while pedaling.The chain drive connection has the lowest possible friction and provides the exact conditions a rider needs to perform high intensity training at any pedal speed and any power output.
There is a significant difference in the mechanical friction of the Revbox Erg compared to the typical tire-roller type trainers. While friction adds to resistance, it is actually an undesirable component as it interferes with a rider’s pedaling dynamics at low cadences.
The major flaw with existing stationary trainer designs is that the tire-roller friction is 2.5 – 3 times more than that of on road rolling resistance. This creates a negative affect for any low cadence strength training. This anomaly is called “stalling” and it refers to when the cadence is sufficiently low enough and the friction sufficiently high enough to cause the trainer unit to attempt to stop rotating when the rider has little leverage on the crankarms (the crank “dead-center”). Stalling is a characteristic unique to magnetic or electro-magnetic trainers as when resistance is increased the unit rotating speed decreases. This extremely low inertia combined with the high friction of the tire-roller connection, will attempt to halt or stall the riders pedal momentum at the point of least leverage (the 12/6 o’clock positions being the “dead-center”).
The Revbox Erg, with mechanical friction less than half of on road rolling resistance, and only 17% of the friction of tire-roller trainers, means that the fan unit does not attempt to stall, regardless of pedal speed. Pedal technique and power transfer are optimised as the rider is able to rotate the cranks with a natural unobstructed motion.
Different trainer designs have varying resistance limits, some of which make many stationary trainers unsuitable for high intensity training. High inertia trainers for example use very heavy rotating weight to help provide resistance. Once up to a speed that has built momentum in the heavy resistance unit, it will experience a tailing off in resistance rate. This phenomenon of “topping out” is when a stationary trainer unit nears its mechanical limit and cannot provide resistance high enough to match the power output of the rider.
Most tire-roller trainers will exhibit both stalling and topping out. The Revbox Erg with its large air braked fan, being 580mm in diameter but only 1.1kg in weight, does not experience either effect and will continue to provide increasing resistance no matter how hard the rider pedals. To match the resistance range of the Revbox Erg, a high inertia stationary trainer would have to weigh over 30kgs (66 pounds).
Magnetic based stationary trainers create resistance by an eddy current of the magnetic field. It is possible for a powerful rider to break free of this current at very high intensities, instantly resulting in zero resistance. Magnetic or electro-magnetic units therefore, have wattage limits, and to train at certain power outputs require undesirably high pedal speeds. While an electro-magnetic trainer has the ability to act as a low or high inertia trainer, it will still always have a limit, combined with the associated issues of the tire-roller interface.
The Revbox Erg lends itself perfectly for use as a rehabilitative tool for sports centers who may prescribe to clients recovering from injury, low intensity, low resistance exercise. While this may seem counter intuitive to the high performance use of the Revbox Erg, as although the resistance ramps up to extremely high levels, the low end resistance is actually much less than standard tire-roller trainers.
Regular stationary trainers with a high friction tire-roller interface require a high initial force to turn the pedals of the bike. In fact, the resistance of this friction interface is approximately four times that of rolling resistance on the road. The Revbox Erg in contrast requires just 17% of the amount of force of a regular trainer for the rider to start rotating the crank arms. For rehabilitative purposes a person recovering from injury is able to ride on a bicycle setup with the Revbox Erg with very low resistance, even less than what is possible to keep a bike in forward motion on the road.
Suitable for not just bike riders recovering from injury, but any person who requires low resistance, low impact, cyclic motion exercise to gradually build back range of movement, coordination and strength. Combining the Revbox Erg with an adjustable fitting bike and a crank set based power meter, a coach or sports science professional will be equipped with an extremely versatile tool that can be utilised for rehabilitation through to high performance fitness testing.
For a rider to begin to train effectively an Athlete Fitness Profile should be developed and tracked over time. A standard VO2 Max test evaluates one aspect of a cyclist’s capacity but for accuracy relevant to the riders cycling discipline other tests should be considered that pertain to certain performance criteria or the goal event.
With its huge resistance range the Revbox Erg can be used as a tool to create an AFP (Athlete Fitness Profile) of a bike rider, which then can be performed at other stages throughout the training plan or season. This is potentially a great additional service to offer for coaches, fitness centers and bicycle stores wanting to raise their level of professionalism within the industry.
An AFP can be different for various disciplines or it may even be specific for certain riders, but it should cover as broad as possible the power, cadence, strength, and coordination aspects of the event or goal requirements. Due to rider fatigue it may be necessary to perform parts of the AFP Test over several hours or days. Training program durations and intensities should be based on specific prescribed values of Power, Heart Rate, Cadence and Incline that are relevant to the rider’s goal performance or event.

The results compared between the two environments need to be analysed as to the differences (rider skill on road, inability to maintain ideal gear ratios, etc) and this worked on in the riders training program
