For a person living in a condo, which vibration-controlled cardio machines are least likely to disturb downstairs neighbors?

When living in a condo, the main culprit behind downstairs complaints isn't usually the mechanical whir of a machine—it is vertical kinetic vibration and footfall impact traveling through the subfloor.

To keep your downstairs neighbors happy, you want machines where your feet never leave the pedals/surface (eliminating stomping impact) and resistance is handled magnetically rather than via friction or air/water fans.

Ranked List of the Best Low-Vibration Cardio Machines for Condos

- **Why it works:** You are entirely seated, meaning your body weight is supported by the saddle rather than pounding into the floor. High-end magnetic resistance bikes (like a [Peloton Bike Go to product viewer dialog for this item.](https://www.google.com/search?ibp=oshop&prds=pvt:hg,pvo:29,mid:576462895436737822,imageDocid:6630658207805546773,gpcid:13818528935954867244,headlineOfferDocid:8660522520833724609,catalogid:1076373423900345109,productDocid:2750673295717175700,rds:PC_13818528935954867244%7CPROD_PC_13818528935954867244&q=product&sa=X&ved=2ahUKEwiOoOKUtMOWAxV97wIHHe0vN8MQxa4PeggIAggBCBEQBQ) or Schwinn Stationary Bike Go to product viewer dialog for this item.) have smooth, weighted flywheels that produce virtually zero vertical vibration.
- **Downstairs risk:** Extremely low—as long as you aren't aggressively standing up to sprint ("out-of-the-saddle" riding), it is nearly silent.

- **Why it works:** Compact models like the [Yosuda Under-Desk Elliptical Go to product viewer dialog for this item.](https://www.google.com/search?ibp=oshop&prds=pvt:hg,pvo:29,mid:576462884120303941,imageDocid:8133022762083873827,gpcid:11233065430081923372,headlineOfferDocid:247085053210662559,catalogid:13315583953434430881,productDocid:10065794714185072354&q=product&sa=X&ved=2ahUKEwiOoOKUtMOWAxV97wIHHe0vN8MQxa4PeggIAggBCBEQDw) allow you to pedal while sitting in a standard chair or couch. Because your feet stay locked in a gliding motion relative to the pedals and your weight is anchored to your chair, floor rumble is practically non-existent.
- **Downstairs risk:** Negligible. They use silent magnetic resistance wheels enclosed in compact plastic casings.[[1]](https://www.google.com/search?q=product&prds=pvt:hg,productid:10065794714185072354,catalogid:13315583953434430881,gpcid:11233065430081923372,mid:576462884120303941&ibp=oshop)

- **Why it works:** Rowers like the [Matrix Indoor Rower Go to product viewer dialog for this item.](https://www.google.com/search?ibp=oshop&prds=pvt:hg,pvo:29,mid:576462550667588830,imageDocid:2691464235551240656,gpcid:12218554939004997093,headlineOfferDocid:5755987427589156849,catalogid:17532002984669640516,productDocid:17865953354333519716&q=product&sa=X&ved=2ahUKEwiOoOKUtMOWAxV97wIHHe0vN8MQxa4PeggIAggBCBEQFw) or magnetic-adjusted models use a smooth pull strap against a magnetic brake. The sliding seat moves horizontally rather than pounding vertically.
- **Downstairs risk:** Low-to-moderate. The "whoosh" sound of air rowers (like a Concept2 Go to product viewer dialog for this item.) or the sloshing of water rowers can carry, but a pure magnetic rower produces a low, steady, non-percussive hum . Just watch out for aggressive sliding or slamming at the catch position.

- **Why it works:** Ellipticals keep your feet on the pedals at all times, avoiding the up-and-down impact of a treadmill. However, cheap or front-drive ellipticals can develop a rocking motion that sends a thumping vibration through the floorboards. Look for heavy, rear-drive commercial-grade units.
- **Downstairs risk:** Low-to-moderate, heavily dependent on your model’s weight and how fluid your stride is.

Machines to Avoid in a Condo

• Standard Treadmills & Walking Pads: Even at a slow walk, the constant heel-strike creates a sharp, percussive shockwave (f = high impact) that travels straight through condo concrete and wood joists alike.
• Air/Fan Bikes (e.g., AssaultBike Go to product viewer dialog for this item. / Schwinn Airdyne Go to product viewer dialog for this item.): The roaring wind-resistance fan creates a high-decibel cutting sound that pierces through shared walls, and the frantic upper/lower body movement often causes lateral shaking.
• Water Rowers: The rhythmic splashing of water creates a deep resonant thud with every stroke that can sound like a muffled drum to a neighbor directly below.

The Secret Weapon: High-Density Equipment Mats

Even the quietest machine can vibrate slightly if placed directly on hardwood or thin condo carpeting. Always pair your machine with a 3/8-inch to 1/2-inch high-density rubber equipment mat (or interlocking EVA foam puzzle tiles). This absorbs the micro-vibrations before they ever reach the structural subfloor.

If you'd like, let me know:

• Your flooring type (concrete slab vs. wood subfloor)
• Your preferred type of workout (intense sweat vs. steady low-impact movement)

I can recommend a specific brand/model or the best thickness for a vibration mat for your setup.

For a condo with downstairs neighbors, the machines least likely to cause complaints are the ones that avoid foot impact, use non-contact resistance, and keep moving parts smooth. The key issue is usually structure-borne vibration (what travels through the floor), not the sound you hear in your own room.

Best choices (quietest to more risky)

Squarefoot Athlete Pulse & Plate## My top picks for a condo

1. Belt-drive magnetic indoor cycling bike — safest bet

A good magnetic bike is probably the lowest-risk choice for downstairs neighbors. The rider stays seated, there are no impacts, and the resistance system is quiet.

Look for:

• Magnetic resistance (not friction pads)
• Belt drive (not chain drive)
• Heavy, stable frame (less wobble)
• Adjustable feet so it doesn’t rock

Good examples:

• Keiser indoor bikes
• Schwinn magnetic cycling bikes

2. Magnetic rower — best for a hard workout

If you want full-body cardio without bothering neighbors, a magnetic rower is one of the strongest options. It avoids foot impact; the main sounds are the seat rolling and the flywheel mechanism.

Avoid:

• Very loud air rowers if you exercise early mornings (the fan noise is noticeable)
• Aggressive rowing where the seat slams forward/back

3. Under-desk elliptical — quietest, but lighter exercise

These are excellent if your priority is “zero complaints,” but they are better for steady movement than intense cardio.

Machines I would avoid in an upstairs condo

• Running treadmill: the repeated heel strikes are the main problem, even if the motor itself is quiet.
• Stair climbers: lots of vertical force and weight shifting
• Jump-style cardio machines: highest vibration risk
• Cheap ellipticals: looseness in joints and pedals can create rhythmic knocking

Setup matters almost as much as the machine

Even a quiet machine can transmit vibration if it sits directly on a hard floor. For any machine:

• Put it on a dense rubber exercise mat (not a thin yoga mat)
• Add vibration-isolating feet/pads if needed
• Place it near a structural wall rather than the middle of a room
• Avoid early-morning or late-night high-intensity sessions
• Keep bolts and joints tightened (loose parts create rattles)

Ellivio Small Home GymIf I were choosing specifically for a second-floor condo, I’d rank them:

1. Magnetic belt-drive bike
2. Magnetic rower
3. Under-desk elliptical
4. Quality elliptical
5. Walking pad

A treadmill would be my last choice unless the building has unusually good sound isolation.

For a condo, the machines least likely to disturb downstairs neighbors are generally the ones that avoid foot impact, use magnetic resistance, have a heavy/stable frame, and don’t create rhythmic floor vibration. The machine’s advertised “quiet” motor noise matters less than the vibration transmitted through the floor.

Best choices for condo living (quietest first)

1. Recumbent magnetic exercise bike — best overall

Noise/vibration risk: Very low

Why it works:

• You are seated, so there is almost no body-impact force.
• Pedaling is smooth and continuous.
• Magnetic resistance avoids friction-pad scraping and reduces mechanical noise.
• A heavier frame tends to stay planted instead of rocking.

Good examples:

— a sturdy, low-impact recumbent option.

— uses magnetic resistance and is designed for quiet home use.

— a seated cross-trainer style option with magnetic resistance.

Best for: early-morning workouts, older buildings, sensitive neighbors, shared walls.

---

2. Under-desk elliptical / seated pedal exerciser — quietest possible

Noise/vibration risk: Extremely low

Why:

• Your feet never strike the floor.
• Small range of motion means very little structural vibration.
• Magnetic resistance models are particularly quiet.

Tradeoff:

• Usually lower workout intensity than a full-size machine.

Good for:

• Daily movement
• Low-impact cardio
• Working while exercising

---

3. Magnetic upright bike or spin bike — also excellent

Noise/vibration risk: Low

Pros:

• Small footprint.
• Smooth belt drive + magnetic resistance can be nearly silent.
• Easy to place on a vibration mat.

Watch out:

• Standing climbs, rocking side-to-side, and aggressive sprinting can send vibration into the floor.

---

4. Elliptical — acceptable, but depends on the model

Noise/vibration risk: Low to moderate

A good magnetic elliptical can be quiet, but the larger moving mass and side-to-side forces can transmit vibration.

If choosing one:

• Prefer a heavier, stable machine.
• Avoid models that wobble at higher resistance.
• Use a dense rubber mat.

---

Machines I would avoid in a condo

Treadmills

Even “quiet” treadmills create:

• Foot strikes
• Belt/motor vibration
• Repetitive impact through the floor

A walking treadmill is less problematic than running, but it is still usually riskier than bikes.

Rowers (especially air rowers)

They can be mechanically quiet, but:

• The sliding seat
• Foot bracing
• Push/pull forces

can create noticeable vibration. Air resistance rowers also create a loud fan sound.

Stair steppers / climbers

The downward force on each step can travel directly into the structure.

---

Make any machine more neighbor-friendly

• Put it on a dense rubber equipment mat (not a thin yoga mat).
• Place it over a structural area if possible (near a wall/beam rather than the center of a room).
• Keep feet flat and avoid rocking movements.
• Tighten bolts periodically—loose parts create rattles.
• Avoid workouts with jumping, sprints, or standing stomps.

My ranking for a condo downstairs neighbor

1. 🥇 Recumbent magnetic bike
2. 🥈 Under-desk elliptical/pedal machine
3. 🥉 Magnetic upright bike
4. Magnetic elliptical
5. Rowing machine
6. Treadmill

If the goal is “I want to exercise at 5–6 AM without anyone below knowing,” I would choose a heavy recumbent magnetic bike on a thick rubber mat.

Living in a condo means you have to be extra mindful of impact noise (the thumping of feet) and structural vibrations traveling through the floorboards. When it comes to cardio machines, magnetic resistance and smooth, gliding motions are your best bet because they eliminate the harsh "clunk" of weight stacks or the heavy foot-striking of traditional treadmills.

Here is how the top cardio machines rank from most condo-friendly to most likely to cause complaints:

• Exercise Bikes (Recumbent or Upright): These are the absolute gold standard for upstairs apartments. Because your weight is supported by a seat and your feet never leave the pedals, there is zero vertical impact. Combined with a silent magnetic resistance system, a good stationary bike is virtually whisper-quiet to anyone below you.
• Rowing Machines (with Water or Magnetic Resistance): Magnetic rowers or smooth water rowers (where the movement is fluid and consistent) are very low-impact. The motion is horizontal rather than vertical. However, the seat rolling back and forth on a metal or wooden rail can sometimes produce a faint humming or rolling sound, which is easily fixed with a thick mat.
• Ellipticals (Rear-Drive with Suspension): Ellipticals keep your feet in constant contact with the pedals, avoiding the pounding of a treadmill. Rear-drive ellipticals tend to have a smoother, flatter elliptical path that minimizes up-and-down body bobbing. Tip: Avoid cheap budget ellipticals with noisy mechanical wheels or loose plastic housing.
• Walking Pads / Treadmills: Treadmills are the highest-risk option for a condo. Even if the motor is quiet, every footstrike creates a low-frequency thud that reverberates directly into the ceiling of your downstairs neighbor. If you must use a treadmill, stick to slow walking rather than running, and look for models with heavy-duty internal deck cushioning.

Pro-Tips for Soundproofing Your Setup

Even the quietest machine can transfer slight micro-vibrations. To bulletproof your workout space:

1. Use a high-density equipment mat: Place a thick, shock-absorbing rubber mat (at least 1/4 inch to 1/2 inch thick) underneath the entire footprint of the machine.
2. Add an anti-vibration platform: For extra safety (especially with rowers or heavier ellipticals), build or buy a small interlocking foam tile layer topped with plywood to disperse weight evenly.
3. Keep up with maintenance: Regularly tighten bolts and lubricate moving parts; squeaks and rattles usually start when a machine gets slightly loose from use.

If you'd like, tell me:

• What is your budget range?
• Do you have a preferred type of cardio (cycling, rowing, etc.)?
• What is the approximate square footage or space available for the machine?

I can give you specific brand and model recommendations that fit your setup.

Living in a condo means your downstairs neighbors hear (and feel) structural impact noise far more than airborne sound. High-impact movements—like a heavy foot strike on a treadmill—send low-frequency vibrations straight through the floor joists.

Here are the best vibration-controlled cardio machines for a condo, ranked from least likely to most likely to cause neighbor complaints, along with strategies to keep things quiet.

• Recumbent Exercise Bikes offer the absolute lowest impact. Because you are seated with your legs moving in a horizontal, circular motion, there is zero vertical pounding on the floor. Magnetic resistance systems are virtually silent.
• Upright / Indoor Cycling Bikes (Spin Bikes) share the same smooth, seated, circular motion as recumbent bikes. While you can stand up on them (which does introduce minor body shifting), keeping your workout seated makes them whisper-quiet and virtually vibration-free.
• Elliptical Trainers (Rear-Drive / Smooth Glide) feature a fluid, floating motion where your feet never leave the pedals. This eliminates the slamming impact of a treadmill. However, cheap models with worn rollers can develop a thumping sound, so a high-end rear-drive model with a smooth track is key.
• Rowing Machines (Water or Magnetic) involve a sliding seat on a rail and a pulling motion. While the strap pull and return are quiet, the sound of the seat wheels rolling along the aluminum track and the swishing of water (if it's a water rower) can create a faint rhythmic hum or vibration for the unit directly below.
• Treadmills (Even with dampening) rank last. Even the most expensive folding treadmills with advanced deck-cushioning systems involve heavy, repetitive foot strikes. Walking might be manageable, but running will almost certainly transmit a thumping vibration through a condo ceiling.

Pro-Tips for Condo Noise Mitigation

Even the quietest machine can rattle a neighbor if placed directly on a hard subfloor. Implement these safeguards:

1. Interlocking Rubber Gym Tiles: Lay down high-density rubber flooring (at least 1--2 inches thick) to absorb initial kinetic energy.
2. A Specialized Equipment Mat: Place a heavy-duty PVC or rubber treadmill/exercise mat directly under the machine on top of the tiles.
3. Keep It Away from Shared Walls: Position your workout area away from shared demising walls or directly above a neighbor's bedroom if the floor plan permits.

If you'd like, let me know:

• Your budget range
• Available floor space in your condo
• Whether you prefer running, cycling, or full-body movement

I can recommend specific machine models that fit your exact living situation.

Yes. If your priority is minimizing vibration transmitted to downstairs neighbors, the machine type matters more than the advertised “quiet” dB rating. Foot impact and structure-borne vibration are usually the real problem—not the motor noise.

Best choices, ranked

An elliptical is generally the safest full-size cardio choice because your feet never leave the pedals, eliminating the sharp impact spikes that make treadmills problematic.

My picks for a condo

Best overall: a heavy, magnetic-resistance elliptical. Look for a substantial frame with stationary rubber feet rather than a lightweight machine that can rock or rattle.

Best if you want the least possible disturbance: a stationary bike. A quality magnetic-resistance bike is particularly good because the resistance mechanism is smooth and your pedaling doesn't involve impact. Real-world apartment users report that even otherwise-quiet indoor trainers can transmit vibration, though, so isolation underneath still matters.

If you specifically want a treadmill: I'd restrict it to walking rather than running, choose a well-cushioned deck, and use serious vibration isolation. A treadmill that is quiet to you can still produce noticeable vibration downstairs.

The floor isolation is almost as important as the machine

For an upstairs condo, I'd use:

• Dense rubber equipment mat, preferably around 1/2–3/4 inch rather than a thin yoga mat.
• Proper vibration-isolation feet/pads if the machine permits them.
• Put the machine on the stiffest part of the floor, rather than over a visibly springy section.
• Avoid early-morning/late-night workouts.
• If possible, don't place it directly above the downstairs neighbor's bedroom.

And don't assume that stacking several soft foam mats solves the problem. Low-frequency vibration can be difficult to isolate with ordinary rubber/foam; one documented condominium treadmill case ultimately required a specially engineered spring isolation system because simpler rubber mounts weren't adequate.

Bottom line: For a condo with someone directly underneath, I'd choose magnetic elliptical → stationary/recumbent bike → rower → walking treadmill → running treadmill, in that order.

If you tell me your budget (e.g. <$1,000, $1–2k, $2k+) and whether you want walking, cycling, elliptical, or running, I can search current models and identify the quietest specific machines worth considering.

Rowing machines and magnetic-resistance exercise bikes are the best vibration-controlled cardio machines for condo living because they eliminate the high-impact foot strikes that create low-frequency noise for downstairs neighbors. While treadmills generate massive structural vibrations, these low-impact alternatives keep both airborne sound and floor vibrations to an absolute minimum.

Best Low-Vibration Cardio Machine Categories

• Magnetic Exercise Bikes : These create almost zero structural vibration. The flywheel spins on a smooth bearing, and the magnetic resistance is completely silent. Your feet never leave the pedals, eliminating foot-strike noise.
• Water or Magnetic Rowers : Rowing features a smooth, horizontal gliding motion. Because your weight is fully supported by the seat, there is no vertical impact. Magnetic rowers are nearly silent, while water rowers produce a soft, rhythmic swooshing sound that rarely penetrates floors.
• Elliptical Trainers : Ellipticals offer a fluid, continuous circular motion. Your feet stay glued to the pedals, so there is no impact vibration. They have a slightly larger footprint than bikes but are excellent for neighbor-friendly full-body workouts.

Recommended Condo-Friendly Machines

Add to list This is the gold standard for rowing machine durability and smooth operation. Its horizontal gliding seat generates minimal floor vibration, though the chain and wind resistance create some consistent airborne noise.

Add to list This bike utilizes a smooth magnetic resistance system and a belt drive instead of a chain. It delivers an incredibly quiet ride with virtually zero mechanical vibration traveling down through the frame.

Add to list A highly rated, budget-friendly alternative that features silent magnetic resistance and a heavy flywheel. It stays firmly planted to prevent any rocking or floor hum during intense sprints.

Add to list Known for its heavy-duty frame and fluid, whisper-quiet stride. The wheels move along durable rails smoothly, preventing the jerky, vibrating thuds common in cheaper ellipticals.

Essential Vibration-Dampening Accessories

To guarantee your downstairs neighbors hear absolutely nothing, you must decouple the machine from your floor using specialized matting:

• High-Density EVA Foam Mats : Standard yoga mats are too soft and will bottom out under heavy equipment. Use interlocking, high-density EVA foam tiles (at least 3/4-inch thick) to absorb mechanical hums.
• Treadmill Isolation Pads : Place thick rubber anti-vibration pads (often made from recycled tires) directly under the feet or corners of your exercise machine. These are specifically engineered to stop structural noise transfer.

If you want to narrow down your choices, let me know:

• Your budget range for the equipment
• Your fitness goals (e.g., weight loss, endurance, full-body workout)
• How much floor space you have available in your condo

If your #1 priority is not bothering the condo below you, I’d rank cardio machines roughly like this:

The important distinction is machine noise vs. vibration. A treadmill can have a quiet motor and still be loud downstairs because footfalls transmit directly through the floor. Even manufacturers acknowledge that footstrike—not motor hum—is the major issue.

My first choice: magnetic exercise bike

For a condo, I'd choose a magnetic-resistance upright or recumbent bike if you don't specifically need a running-like workout. It's probably the safest combination of effective cardio, small footprint, and minimal structure-borne vibration.

Best if you want a full-body workout: magnetic elliptical

A good magnetic elliptical is probably the best compromise if you want something more vigorous and involving your upper body. Current models specifically advertise quiet magnetic operation—for example:

Sunny Health & Fitness Ultra Silent Smart Elliptical

$599.99

The elliptical's smooth motion avoids the repeated footstrike of a treadmill. However, I'd favor a solid, stable machine with smooth bearings and magnetic resistance over an inexpensive machine that rocks or rattles. User experiences also suggest that construction of the building matters enormously.

Magnetic rower: surprisingly good, with one caveat

A magnetic rower can be excellent. I'd specifically avoid an air-resistance rower if minimizing airborne noise is the goal—the fan/airflow gets noticeably louder as you increase intensity. A magnetic model is considerably more appropriate for a condo.

MERACH Magnetic Rowing Machine

$399.99

There's some real-world evidence that rowers can be very neighbor-friendly when properly isolated, although experiences vary considerably by building and technique.

What I'd avoid

Running on a treadmill, especially in a wood-frame condo. Even sophisticated rubber mats don't necessarily solve low-frequency vibration. A professional condo vibration-control case found that ordinary rubber isolation wasn't sufficient for treadmill-induced low-frequency vibration; a much more elaborate low-frequency isolation system was required.

I'd also avoid:

• Stair climbers
• Steppers
• Jumping/rebounder machines
• Air bikes if noise is a major concern
• Anything involving repeated hard footfalls

The setup matters almost as much as the machine

For whichever machine you choose:

1. Use a dense rubber equipment mat, not just a thin yoga mat.
2. Put the machine away from the wall/shared structural elements if possible.
3. Don't exercise during your building's quiet hours.
4. Keep the machine well maintained—loose bearings, pedals, and frames can create surprisingly annoying vibration.
5. If possible, ask the downstairs neighbor to listen during a 5-minute test session before committing to the machine.

And if your condo has concrete slab floors, you're in a substantially better situation than if it has wood-joist construction; the latter tends to transmit impact vibration much more readily.

Bottom line: For maximum neighbor-friendliness, I'd pick magnetic exercise bike > magnetic elliptical > magnetic rower. If you tell me your budget, available floor space, and whether you want primarily fat-loss cardio, HIIT, or steady-state exercise, I can narrow that down to 3–5 specific machines.

When living in a condo, the primary culprit behind neighbor complaints isn’t actually the mechanical noise of a machine (like a whirring motor)—it is structural vibration and impact thumping traveling through the subfloor and ceiling joists.

To keep your downstairs neighbors happy, you need a machine that features continuous foot/body contact (zero lift-and-strike motion) and magnetic or frictionless resistance.

The best cardio options for a condo, ranked from least likely to most likely to cause disturbances, include:

• Magnetic Upright and Recumbent Exercise Bikes (Gold Standard): Seated stationary bikes that utilize a magnetic resistance system and a belt drive (instead of a chain) are virtually silent. Because your body weight is entirely supported by the seat and your feet never leave the pedals, there is zero vertical impact or rhythmic pounding on the floor.
• Magnetic Resistance Ellipticals (Standing or Compact/Under-Desk): Unlike treadmills, your feet remain in constant contact with the footplates throughout the entire rotation . Quality rear-drive or compact magnetic ellipticals (such as those by Niceday Go to product viewer dialog for this item. or Schwinn) create a smooth, fluid, low-impact motion that generates minimal lateral or vertical vibration.
• Magnetic Indoor Rowers: Air and water rowers create a rushing or wooshing sound with every stroke (and water tanks can produce a slight sloshing vibration). A magnetic-resistance rower provides a "silent pull" where the sliding seat on its rail and the magnetic flywheel produce almost zero ambient noise or floor rumble.
• High-End Walking Pads / Under-Desk Treadmills (Use with Caution): While marketed as compact, even the quietest walking pads produce a repetitive structural "thump" from your footstrikes transmitting straight into the floorboards. If you choose one, stick strictly to slow walking rather than running, and use mitigation tools.

Pro-Tips for Absolute Vibration Control

No matter which machine you choose, you can completely isolate the equipment from your condo's structure by implementing these steps:

1. Interlocking High-Density Rubber Mats: Place a thick (1 1 2 inch to 3 1 4 inch) rubber equipment mat or puzzle-piece stall mat underneath the machine to absorb micro-vibrations.
2. Check for Loose Bolts: Vibrations often worsen over time if a machine's frame components develop loose hardware. Routinely tighten all screws and joints.
3. Avoid Hardwood Direct Placement: If your condo has exposed hard flooring, the acoustic resonance is high. Positioning the machine over a carpeted area or adding an extra layer of foam-underlayment beneath your rubber mat adds critical acoustic dampening.

If you tell me your preferred workout style (cycling, standing up, etc.) and your budget range , I can suggest specific models that fit your space.

For a condo, the key is structure-borne vibration, not just how loud the machine sounds. A machine can be nearly silent to you but still transmit thumps through the floor.

Best choices, from least to most likely to bother downstairs neighbors

1. Recumbent exercise bike — best overall

• Your body stays seated, so there is essentially no foot impact.
• Magnetic resistance is very quiet and smooth.
• A wide, heavy base tends to be stable rather than rocking.
• Particularly good if you want to exercise early/late without worrying about impact noise.

2. Recumbent cross-trainer / seated elliptical — excellent

• Very low impact because you're seated and the pedals move smoothly.
• Magnetic resistance avoids the mechanical noise of friction systems.
• Some models are heavier, which can help stability.
• A particularly good compromise if you want more full-body exercise than a bike.

3. Conventional elliptical — generally very good

• Your feet stay in contact with the pedals, so there is little or no impact.
• Magnetic-resistance models can be extremely quiet.
• The caveat is that fast, forceful elliptical use can still create floor vibration, particularly on lightweight floors.

4. Magnetic rowing machine — quiet, but somewhat more vibration-prone

• Magnetic rowers are much quieter than air-resistance rowers.
• However, the seat rolls back and forth and you push/pull against the machine, which can introduce some vibration.
• Good choice if you specifically want rowing, but I'd put it behind a recumbent bike or elliptical for condo living.

Machines I'd avoid over a neighbor

Treadmills are the big one. Even a "quiet" treadmill can transmit repetitive impact from every footstrike. Running is much worse than walking. Jump ropes, stair steppers, mini-trampolines, and other machines involving repeated foot impact are also poor choices.

One important trick

Whatever you buy, put it on a dense, purpose-built equipment mat designed for vibration isolation, rather than a thin yoga mat. Also place the machine away from walls and don't let cables, furniture, or the machine itself contact anything that can act as a vibration bridge.

If minimizing disturbance is your #1 priority, I'd choose a heavy recumbent magnetic bike. If you want a more strenuous full-body workout, I'd move to a seated/recumbent elliptical, then a magnetic elliptical.
