InfraStar Bike Review: Vacuactivus Infrared Vacuum Cycling Technology
The Vacuactivus InfraStar is a stationary exercise bike built inside a sealed capsule that combines vacuum resistance, infrared heat, and a stack of recovery technologies into one low-impact cardio session. A pump lowers air pressure around the lower body, adjustable from 0 to 30 mbar, while infrared warms tissue to roughly 4 mm depth and raises core temperature by about 2C in fifteen minutes, and the client pedals in a semi-reclined position that keeps load off the spine.
We build this bike, so this review separates two things the sales pages blur together. The mechanism is real and does what the physics predicts: more sweat, more lower-body blood flow, low joint impact. The calorie figures attached to it range from 800 to 1,500 per session across different sellers with no shared measurement method behind them, and none of the numbers agrees with the others. Read the mechanism as verified and the specific numbers as marketing estimates.
Vacuactivus, operating as Cryonick Wellness Technology Factory, has engineered vacuum infrared cardio equipment since 2009 (over 15 years). This is a Product Review by the manufacturer, not a sales page. The physics gets the credit it deserves, and the marketing gets the scrutiny it usually does not. Nothing here is medical advice; client-facing therapeutic, weight-loss or cellulite claims should be reviewed with a qualified regulatory or medical professional before publication in marketing materials.

What the InfraStar Bike Actually Is
Strip away the marketing and the InfraStar is a recumbent exercise bike with the lower body enclosed in a sealed capsule and a set of therapy systems layered on top. The rider sits semi-reclined, legs and hips inside the capsule, and pedals a normal cycling motion. What makes it different from a gym recumbent is what surrounds the legs. A vacuum pump lowers the air pressure inside the capsule, adjustable from 0 to 30 mbar of negative pressure. Infrared panels warm the enclosed tissue. On top of that base, the InfraStar stacks options that vary by configuration: cryotherapy air through the Cryonick system, collagen and chromotherapy lighting, oxygen and ozone, EMS, and aromatherapy.
The interface is a 10-inch touchscreen with a VR-style 3D workout menu, real-time metrics, and streaming from Netflix, Spotify and Radio Garden, plus remote access through the Vacuactivus_User app. The body is fiberglass. That feature list is long, and a fair review says so plainly: the core of the machine is vacuum plus infrared plus cycling, and everything else is an add-on that a buyer can weight according to whether it matters to their service. The semi-reclined position is not a comfort detail – it is the reason the machine reaches clients who cannot use an upright bike, and it is arguably the most important single design choice in the whole unit.

How Vacuum and Infrared Cycling Works
The mechanism is the part of this machine that holds up under scrutiny, so it is worth explaining precisely. Start with the vacuum. The capsule seals around the waist, and a pump removes air until the pressure around the legs and hips drops below atmospheric, adjustable across a 0 to 30 mbar range. That negative pressure draws blood toward the lower body, increasing circulation through the hips, thighs and abdomen, which is the same principle the Hypoxi and Exclusive Shape systems use. More blood flow to a region means more oxygen and nutrient delivery and faster clearance of metabolic waste through that tissue.
Now add infrared. The panels warm the enclosed skin and the tissue beneath it, penetrating to around 4 mm and raising core temperature by roughly 2C over fifteen minutes. Warmer tissue means dilated vessels, more sweat, and a higher metabolic rate during the session. Cycling drives the whole thing: the muscular work generates the cardiovascular load, and the vacuum and infrared modify the environment that work happens in. That combination genuinely differs from a standard bike, and for the specific goals of lower-body circulation and a heat-loaded low-impact session, it does what it claims.
Where honesty is required is the leap from those mechanisms to specific outcomes. Increased circulation to fat-rich areas is a real effect; the claim that this preferentially burns fat from those exact zones is a much stronger statement that the underlying physics does not clearly support. Treat the mechanism as established and the targeted-fat-loss framing as a hypothesis the marketing states more confidently than the evidence does. The same caution applies to detox-through-skin claims that appear on some category pages: increased sweating is real, but the medical meaning attached to it in marketing goes further than the physiology of sweat clearance actually supports. For the general category education on vacuum training as a concept without the marketing overlay, see stationary bikes with infrared and vacuum fitness for body shaping which walks the mechanism at the category level.
About Those Calorie Numbers
Here is where a review earns its keep, because the calorie claims for this bike do not agree with each other. Our own product page states 800 to 1,000 kcal per 30-minute session. A dealer listing for the same machine states up to 1,500. And our own guide to stationary bikes puts a regular exercise bike at 600 to 800 kcal per hour, not per half hour. Those three numbers cannot all be right, and none of them arrives with a stated measurement method – no VO2 testing, no metabolic cart, no protocol stated.
What is defensible physiologically: infrared heat and the effort of cycling do raise energy expenditure above a room-temperature ride, mostly through thermoregulation and increased sweat, and a heated low-impact session can feel harder and burn somewhat more than the same effort cold. What is not defensible is a specific figure like 1,500 calories in 30 minutes, which would exceed what most athletes burn in an hour of hard cycling. The physical implausibility of that number matters, because a buyer comparing options deserves to know when a spec is a marketing estimate rather than a measured result.
The honest position for a buyer is this: the InfraStar burns more than an equivalent unheated ride, the added burn comes largely from heat load rather than from the vacuum melting fat, and any single calorie number quoted for it should be treated as a marketing estimate until someone publishes a measured protocol. That caveat does not weaken the machine. It just moves the sales pitch from a number nobody can defend to a mechanism anyone can. For the comparison of a home-market exercise bike case where the vacuum-infrared advantage matters vs where it does not, see Best Exercise Bike for Home Gym: When Infrared Vacuum Beats Regular Cycling which walks the honest comparison at the home-market level.
InfraStar vs InfraStar S: The Two Generations
Vacuactivus ships the InfraStar in two generations, and a buyer should know which one they are quoting. The original InfraStar is the full-featured capsule bike described above, with the widest therapy stack: cryotherapy, oxygen and ozone, EMS, collagen and color light, aromatherapy, VR menu and streaming. The InfraStar S second-generation bike is the second-generation model, built on the same core of vacuum resistance, infrared heating and ergonomic cycling but refined for comfort, performance and efficiency.
The S generation uses a semi-lying ergonomic position that reduces joint strain further, adds collagen and color therapy lighting, and runs a smart touchscreen with preset training programs, in a more compact footprint aimed at studios and home users with limited space. In practice the S trades some of the maximalist add-on stack of the original for a cleaner, more space-efficient package, which suits an operator who wants the core vacuum-infrared effect without paying for every peripheral therapy. Neither is simply better; they target different buyers. A high-end body-shaping studio building a signature service may want the fuller original; a smaller studio or a home installation prioritizing footprint and simplicity may prefer the S. Confirm which generation a given price and spec sheet refers to before comparing, because the two are easy to conflate under the shared InfraStar name.

How It Compares to the Category
The InfraStar sits in a category with two other named approaches, and a fair review places it among them rather than pretending it stands alone. Exclusive Shape builds the closest direct equivalent: the Vacu Bike and Infra-Vacu combine vacuum and infrared in a lower-body capsule with a recumbent cycling position, sold through dealers like Rehabmart with standard and premium tiers. It is the nearest like-for-like competitor, and the main differences are in the therapy stack and the software rather than the core principle. Both are broad low-impact cardio-plus-vacuum-infrared stations, both target similar wellness-studio and medspa buyers, and both would serve a body-shaping service well.
Hypoxi takes a different path. Its Vacunaut, S120 and L250 systems are built around clinical body-targeting rather than a general cardio session: the Vacunaut uses a bodysuit with 122 pressure chambers to direct blood flow specifically at abdominal fat, and Hypoxi studios run a consultative, trial-session model with programs engineered per client. That is a narrower, more medicalized proposition than the InfraStar, which is a broader cardio-plus-recovery station. The Hypoxi approach is a legitimate service model that fits operators building a franchise-style consultative practice around targeted abdominal work rather than a general body-shaping and cardio bike.
The practical takeaway for a buyer: if the goal is targeted abdominal work with a franchise-style consultative service, Hypoxi is purpose-built for it; if the goal is a versatile low-impact cardio and recovery station that also does body shaping, the InfraStar and the Exclusive Shape units are the broader tools. None of the three is a weak product; they are aimed at different service models, and the right choice follows from the service, not from a feature count. For B2B operators mapping the wider procurement decision across the exercise-bike category, our B2B buying guide for exercise bikes covers the fuller procurement walk-through.
Who the InfraStar Is Actually For
The strongest case for the InfraStar is not the client a standard bike already serves – it is the client a standard bike turns away. Someone in their fifties with chronic knee pain does not get on an upright spin bike. Someone with a herniated disc does not run on a treadmill. Someone forty pounds overweight does not last on high-impact cardio. The InfraStar reaches all of them, because the semi-reclined position removes spinal load, the low-impact pedaling protects the joints, and the enclosed environment makes a gentle session feel productive.
For a wellness studio, medspa, rehabilitation clinic or longevity center, that is the commercial point: the machine fills a gap in the cardio market rather than competing for the client who already has ten cardio options. It works as a body-shaping service, a low-impact conditioning tool for deconditioned or older clients, and a recovery station. It pairs naturally with adjacent low-impact BodyShape equipment – the VacuStar traka za trčanje extends the same vacuum-infrared principle to walking, and operators building a full low-impact circuit typically pair the bike, treadmill and stepper across the Vacuactivus BodyShape category range.
Where it fits less well: a high-performance athletic facility whose clients want maximal cardiovascular load will find the capsule and the heat a constraint rather than a feature, and a budget gym competing on price will not recover the cost of a capsule bike against a rack of standard spin bikes. The honest filter is the clientele. If a meaningful share of your prospective clients are turned away by conventional cardio, the InfraStar converts them; if they are not, it is a premium novelty rather than a gap-filler. Model the customer count that specifically requires the capsule, not the customer count that would tolerate one, before signing a purchase order.
Gdje se Vacuactivus uklapa
Vacuactivus, operating as Cryonick Wellness Technology Factory, has engineered vacuum infrared cardio equipment since 2009 (over 15 years), and the InfraStar sits in the BodyShape line alongside vacuum infrared treadmills, the InfraStepper and related capsules. The company sells factory-direct with OEM and leasing options, which matters for a studio financing a capital purchase or a distributor building a private-label line. Specifications, current pricing and the InfraStar S configuration are on the InfraStar product page, and the wider BodyShape category page covers how the bike fits alongside the treadmill and stepper for operators building a full low-impact circuit.
Apply the same scrutiny to us that this review applied to the calorie claims: ask for the measured session data if a number matters to your sales pitch, confirm which generation a quote covers, and match the therapy stack to what your service actually uses rather than paying for peripherals you will not switch on. A manufacturer confident in the equipment will provide measured performance data on request and will name which generation is quoted; one that quotes round marketing numbers without methodology is telling you something about how much of the spec sheet is verified.
Često postavljana pitanja
Q1. What is the InfraStar bike and how does it work?
The InfraStar is a recumbent stationary bike built inside a sealed capsule that combines vacuum resistance, infrared heat and cycling into one low-impact session. The rider sits semi-reclined with the legs and hips enclosed, and a pump lowers the air pressure around the lower body, adjustable from 0 to 30 mbar. That negative pressure draws blood toward the hips, thighs and abdomen, increasing circulation there. Infrared panels warm the enclosed tissue to roughly 4 mm depth and raise core temperature by about 2C over fifteen minutes, which increases sweat and metabolic rate during the session. The cycling provides the cardiovascular work while the vacuum and infrared modify the environment it happens in. On top of that base, the InfraStar layers optional therapies – cryotherapy, collagen and color light, oxygen, EMS and aromatherapy – plus a 10-inch touchscreen with streaming and app control. The core is vacuum plus infrared plus cycling; the rest is configurable.
Q2. How many calories does the InfraStar bike burn?
Honestly, nobody has published a measured figure, and the claims disagree. Vacuactivus product pages state 800 to 1,000 kcal per 30-minute session, a dealer listing (RecovAthlete) states up to 1,500, and a regular exercise bike burns roughly 600 to 800 kcal per hour for comparison. Those numbers cannot all be right, and none arrives with a stated measurement method. What is physiologically defensible: infrared heat plus cycling does raise energy expenditure above a room-temperature ride, mostly through thermoregulation and increased sweat, so a heated session burns somewhat more than the same effort cold. What is not defensible is a specific figure like 1,500 calories in 30 minutes, which would exceed what most athletes burn in an hour of hard cycling and is physically implausible for a low-impact recumbent session regardless of heat load. Treat any single calorie number quoted for the InfraStar as a marketing estimate until a measured protocol exists. The mechanism raising the burn is real; the exact figure is not established.
Q3. How does an infrared vacuum bike burn more calories than a regular bike?
Through added heat load and circulation, not through anything magical about the vacuum. The infrared panels warm the enclosed tissue, raising core temperature by about 2C over fifteen minutes, and the body spends energy on thermoregulation – cooling itself through increased sweat and blood flow – on top of the energy spent pedaling. That thermoregulatory cost is the main reason a heated session burns more than an unheated one at the same effort. The vacuum contributes by increasing blood flow to the lower body, which supports the working muscles and the sweat response, but the vacuum itself does not burn fat or add large numbers of calories. So the honest mechanism is cycling effort plus heat-driven thermoregulation, with the vacuum improving lower-body circulation. That is a real increase over a standard ride, but it is a modest one driven by heat, not the dramatic figures some listings quote. Anyone selling it should lead with the mechanism rather than a calorie number that cannot be defended.
Q4. What is the difference between InfraStar and InfraStar S?
They share the same core – vacuum resistance, infrared heating and ergonomic cycling – but target different buyers. The original InfraStar is the full-featured capsule bike with the widest therapy stack: cryotherapy, oxygen and ozone, EMS, collagen and color light, aromatherapy, VR menu and streaming. The InfraStar S is the second-generation model, refined for comfort, performance and efficiency, using a semi-lying ergonomic position that reduces joint strain, collagen and color therapy lighting, and a smart touchscreen with preset programs, in a more compact footprint. In practice the S trades some of the maximalist add-on stack for a cleaner, space-efficient package. A high-end body-shaping studio building a signature service may want the fuller original; a smaller studio or a home installation prioritizing footprint may prefer the S. Neither is simply better. Confirm which generation a price and spec sheet refers to before comparing, since the two are easy to conflate under the shared name.
Q5. Does the InfraStar bike actually reduce cellulite?
It supports the appearance changes associated with cellulite rather than removing fat, and the honest framing matters. The mechanism is real: vacuum increases circulation to the hips and thighs, infrared warms the tissue, and cycling works the lower-body muscles, and that combination can improve the appearance of cellulite and skin texture over a series of sessions. What the physics does not clearly support is the stronger claim that vacuum cycling preferentially burns fat from the exact zones it targets. Increased circulation to fat-rich areas is established; targeted fat loss from those areas is a hypothesis the marketing states more confidently than the evidence does. Presented accurately, the bike is a body-contouring and appearance tool with a genuine circulatory and thermal effect, maintained by continued sessions rather than a one-time fix. Presented as spot fat reduction, it sets up disappointment. Sell the circulation, heat and low-impact conditioning, which are real, rather than a targeted-fat claim the underlying physics does not back.
Q6. Who should use an infrared vacuum bike?
The strongest fit is the client a standard bike turns away. Someone with chronic knee pain, a herniated disc, significant excess weight or limited mobility often cannot use an upright bike or a treadmill, and the InfraStar reaches them because the semi-reclined position removes spinal load and the low-impact pedaling protects the joints. It suits deconditioned and older clients, rehabilitation programs, and anyone who needs gentle cardio that still feels productive. For a wellness studio, medspa, rehab clinic or longevity center, that gap-filling role is the commercial point – it converts clients conventional cardio cannot serve. It fits less well for a high-performance athletic facility whose clients want maximal cardiovascular load, where the capsule and heat become constraints, and for a budget gym competing on price against a rack of standard bikes. The honest filter is the clientele: if a meaningful share of prospective clients are turned away by conventional cardio, the InfraStar converts them; if not, it is a premium novelty.
Q7. How does InfraStar compare to Hypoxi or Exclusive Shape?
They are three approaches to the same category, aimed at different service models. Exclusive Shape builds the closest direct equivalent – the Vacu Bike and Infra-Vacu combine vacuum and infrared in a recumbent lower-body capsule, sold through dealers with standard and premium tiers, with differences from the InfraStar mostly in the therapy stack and software rather than the core principle. Hypoxi takes a clinical, targeted path: its Vacunaut uses a bodysuit with 122 pressure chambers to direct blood flow specifically at abdominal fat, and Hypoxi studios run a consultative, trial-session model with per-client programs. That is narrower and more medicalized than the InfraStar, which is a broader cardio-plus-recovery station. If the goal is targeted abdominal work with a franchise-style consultative service, Hypoxi is purpose-built for it. If the goal is a versatile low-impact cardio and recovery station that also does body shaping, the InfraStar and the Exclusive Shape units are the broader tools. None is a weak product; the right choice follows from the service model.
Q8. Is a vacuum infrared bike worth it for a studio?
For the right studio, yes, and the case rests on reaching a client conventional cardio cannot. A vacuum infrared bike is a premium capital purchase, so it earns its cost by opening a service the studio could not otherwise offer – low-impact conditioning and body shaping for deconditioned, older, injured or overweight clients who are turned away by upright bikes and treadmills. It works as a signature body-shaping service, a rehabilitation-friendly cardio tool, and a recovery station, often booked in series, which suits membership and package models. Vacuactivus sells factory-direct with OEM and leasing options, and business financing spreads the purchase, which matters for a studio testing the service before committing capital. It is not worth it for a facility whose clients already have ample cardio options and want maximal athletic load, or a budget operation competing on price. Run the numbers on the specific clientele it would convert rather than on a generic calorie or fat-loss claim, and confirm which generation and therapy configuration the quote covers.
Zaključak
The InfraStar is a recumbent stationary bike inside a sealed capsule combining vacuum resistance from 0 to 30 mbar, infrared heating to approximately 4 mm depth raising core temperature about 2C over 15 minutes, and semi-reclined low-impact cycling. The mechanism is real and does what the physics predicts: more sweat, more lower-body blood flow, low joint impact. The calorie figures attached to the machine (800 to 1,000 per 30 minutes on our product page, up to 1,500 on a dealer listing, 600 to 800 per HOUR for a regular exercise bike) cannot all be right, and none arrives with a stated measurement method. Treat the mechanism as verified and any specific calorie number as a marketing estimate.
Two generations exist: the original InfraStar with the fuller therapy stack, and the InfraStar S with a refined semi-lying position and compact footprint – different buyers, not a strict upgrade. In the category, Exclusive Shape builds the closest equivalent and Hypoxi runs a narrower clinical body-targeting model with 122 pressure chambers; all three are legitimate under their own service models. The commercial case is strongest where the InfraStar reaches a client conventional cardio turns away – chronic knee pain, herniated disc, significant excess weight, limited mobility – and weakest as a premium novelty in a facility whose clients already have ten cardio options. Sell the mechanism, hedge the calorie number, and match the therapy stack to what the service actually uses. That is the honest sales pitch, and it holds up longer than a number nobody can defend.
