MERACH prints the lowest noise figure we found for any exercise bike: "under 15dB" for its S19 Pro recumbent, with no cadence, resistance level, rider weight or distance attached. Among spin bikes, JOROTO says its X4S runs "Under 20 dB", and FED Fitness gives the YOSUDA EB1 the same ceiling. Yesoul writes an exact 30dB for its G1M Plus, and the one upright with a figure, the FED Fitness EB5, says 45dB.
The best-known brands publish nothing at all. Peloton, Schwinn, BowFlex, NordicTrack, Echelon, Keiser, Stages and Sunny Health & Fitness print no figure for any bike we read, so every number on this page comes from a direct-to-home brand. That is why the second half of the page is about what reaches the floor under an apartment bike: the resistance, the drive, the flywheel, and what Schwinn, BowFlex, Peloton and NordicTrack write about mats, leveling and floors.
Our picks are listed above, with full specifications for each.
Fifteen to forty-five decibels, and not one cadence
Every figure we found for an exercise bike, sorted by the kind of claim it is:
- Under 15 dB: MERACH S19 Pro Recumbent and S19 Recumbent Cross Trainer.
- Under 20 dB: JOROTO X4S and the YOSUDA EB1.
- Under 25 dB: MERACH S26, S26 Aura, S36 and S29 Eco; JOROTO X2; Pooboo D525, D525X and D576.
- Exactly 30dB: Yesoul G1M Plus and S3, from one block of copy that appears on both pages.
- Exactly 45dB: FED Fitness EB5 Upright.
None of these makers says how fast the pedals were turning, which resistance level was set, how heavy the rider was or how far away the microphone stood, and every figure is in plain dB, with no A-weighting named. The only maker that mentions cadence at all prints no figure: NordicTrack's advice on bikes for small spaces says the most reliable way to confirm noise is "to review the model's instrument noise report", which it describes as "expressed in decibels at 60 and 90 RPM". We found no such report on the pages for NordicTrack's S24, X24 or 10 Recumbent.
For scale, the US National Institute on Deafness and Other Communication Disorders (NIDCD) puts whispering at 30 dB and a humming fridge at 40 dB. Every ceiling on this page puts a bike in operation below a whisper, and MERACH's 15 is half that number. We report these figures as the makers' promises; none comes with the conditions that would let anyone check it.
"Under 20 dB" and "30dB" are different kinds of claim. A ceiling says the bike stays below a number in whatever test the maker ran; an exact figure says what one test read. Neither maker describes its test, so Yesoul's 30dB could describe a harder ride than JOROTO's ceiling or an easier one, and the 10 decibels between the two numbers prove nothing. We rank the ceilings against each other, lowest first, and keep the exact figures apart.
Even among the ceilings, a lower number is a bolder promise, not a measured gap. The order means most inside one maker's list. MERACH puts its two S19 recumbents under 15 dB and every spin bike it rates under 25 dB, and JOROTO puts the X4S 5 dB below the X2, though both have six-magnet resistance and a 35 lb flywheel; the X4S adds a multi-groove belt. Since no maker names a distance or a weighting, a gap between two brands here is not a like-for-like difference either.
Magnetic, friction and air resistance
Magnetic resistance brakes the flywheel with magnets that do not touch it, and every bike with a figure on this page uses it. Schwinn's 2025 manual for the IC3.5 puts the case plainly: "Our Indoor Cycles are some of the quietest available because they use belt drives and magnetic brake resistance." The manuals for its 180 upright and 280 recumbent carry the same paragraph for their own bike types, and with it a warning. Because the resistance is so quiet, Schwinn says, "you will occasionally hear other slight mechanical noises", since "there are no fans, friction belts, or alternator noises to mask these sounds".
Friction resistance presses felt pads against the flywheel instead. Sunny Health & Fitness still sells one, the Smart Pro Belt Drive Indoor Cycling Exercise Bike, with a "dual felt pad resistance system", and calls its belt drive quiet without a figure. The care guide Johnson Health Tech publishes for its 2025 Schwinn cycles tells owners of a bike with "a felt resistance/brake pad" to lubricate it. No maker prints a figure for a friction bike, so the case for magnets in an apartment rests on the makers' words rather than on numbers.
Two bikes here set their resistance electrically. The FED Fitness EB5 lists "Electromagnetic" resistance and needs an outlet, and MERACH's S29 Eco sets its magnetic resistance automatically on power it makes itself. Air resistance, the third kind, gets a section of its own below.
Belt or chain, and how heavy the flywheel is
Where these makers name the drive, it is a belt. JOROTO's X4S has a "Multi-groove Silent Belt Drive (4.29:1 Ratio)", MERACH's S26 and S36 a "silent belt drive", and Yesoul credits its 30dB to a "Tesla-grade belt system". Keiser makes the same case for the Poly-V belt on its M3i, without a figure. MERACH does not name the drive on the S19 Pro or the S29 Eco, and FED Fitness does not on the EB1.
Chain drives are getting harder to find. Sunny's chain-drive SF-B901 and SF-B1203 were both marked unavailable on its store on October 13, 2026. Johnson Health Tech's care guide gives a chain a job a belt does not have: "Cycles with drive chains - clean and lubricate the chain." For a belt, the same guide's warning sign is a grinding noise when you pedal, which it says "is typically caused when a drive belt is misaligned or going bad."
Flywheel weights run from 6.6 lb on MERACH's S19 Pro to 40 lb on its S29 Eco and 45 lb on the YOSUDA EB2, with the JOROTO X2 and X4S and the YOSUDA EB1 at 35 lb. No maker ties a flywheel's weight to its figure, and the lightest flywheel here belongs to the bike with the lowest ceiling, so weight alone does not predict the number on the page. Yesoul names its flywheel's materials, cast iron with an aluminum ring, but not its weight.
Floors above other people: what the manuals say
A bike has no footstrike, unlike a treadmill, but the makers' documents still put the floor at the center of the noise question. Schwinn's 2025 manuals, and the care guide Johnson Health Tech publishes with them, answer why a delivered bike sounds louder than the one in the shop: "All fitness products seem quieter in a large store showroom because there is generally more background noise than in your home. Also, there will be less reverberation on a carpeted concrete floor than on a wood overlay floor. Sometimes a heavy rubber mat will help reduce reverberation through the floor. If a fitness product is placed close to a wall, there will be more reflected noise."
NordicTrack writes for apartments directly. Its advice on bikes for small spaces says "Quiet is relative to your building's construction, your neighbors' schedules, and the time of day you ride", and ends: "Place the bike on an anti-vibration mat to reduce transmitted vibration to floors below." Peloton puts a 72 by 36 inch mat in its bike packages and sums it up in one line: "Protective mat fits under Bike to improve stability and reduce noise."
BowFlex's manuals for the C6 and the IC Bike SE set the base rule: "For safe operation, the location must be on a hard, level surface." Taken together, a heavy rubber mat on a hard floor, with the bike a little way from shared walls, is the setup these makers describe for a flat with neighbors below or beside. None of them gives a figure for what the mat or the gap from the wall saves.
Leveling, loose bolts and the squeak that follows
A rocking bike is the one problem every manual here tells you how to fix. Schwinn's IC3.5 manual says: "If the Indoor Cycle rocks on the floor after being set down, turn the leveling feet underneath the front or rear stabilizer until the rocking motion is eliminated." BowFlex's C6 manual lists "Unit rocks/does not sit level" in its troubleshooting table, with the levelers as the fix, and warns that adjustment "may not be able to compensate for extremely uneven surfaces", in which case the bike should move to a level area.
On a new bike, the manuals blame loose hardware before the drive. The IC3.5 manual says parts that are not tightened "will seem loose and may cause irritating noises", and its answer to a squeaking or chirping bike is to check that it stands level, then loosen the assembly bolts, grease the threads and tighten them again. Johnson Health Tech's care guide adds that frame bolts can loosen after the first few rides "as the product settles to the floor", and asks owners to check them after those first uses and then monthly. BowFlex traces a clicking sound when pedaling to the pedal and crank connection.
Fan bikes belong on a list of their own
An air bike, or fan bike, makes its resistance by pushing air with a fan, so the harder you pedal, the more air it moves. Schwinn's Airdyne AD7 manual states the rule in one line: "To increase the air resistance and workload, increase your level of activity." The arms drive the same fan, since on the AD7 "the Pedals, Handlebars and Resistance Fan are connected". On a fan bike, then, a harder interval also means more air moving through the fan.
Concept2's BikeErg uses an air flywheel with a damper that Concept2 calls your "gearing", and describes the ride as "smooth, quiet and responsive" without a figure. Schwinn for the Airdyne AD7, Concept2 for the BikeErg, Sunny for its Tornado fan bikes and Pooboo for its S329 air bike print no decibel figure on the pages and manuals we read, so no fan bike appears among the picks or beside a magnetic bike's number.
These makers give no decibel figure on the US pages we read for these bikes, or in the manuals we could open:
- Peloton: Cross Training Bike and Cross Training Bike+.
- Schwinn: IC4, IC3.5, 180 upright, 280 recumbent and the Airdyne AD7.
- BowFlex: C6 and IC Bike SE.
- NordicTrack: S24, X24 and 10 Recumbent, sold on "Silent Magnetic Resistance".
- Echelon: EX-5s, EX-7s and EX-8s.
- Sunny Health & Fitness: its indoor cycles, uprights and recumbents, with words such as "nearly silent" instead of numbers.
- Keiser, Stages, Technogym and Garmin: Keiser calls the M3i's magnetic resistance smooth and quiet, and Garmin calls the Tacx NEO Bike Plus "virtually silent".
SOLE comes closest to a number. Its own blog says "SOLE spin bikes operate below 30 decibels using magnetic resistance and belt drives" and names the SB1200 and SB900, but neither appears on SOLE's US store, and the bikes it does sell, the LCB, LCR and R92, carry no figure.
How we chose
We read the US product pages of MERACH, JOROTO, FED Fitness, Yesoul, Pooboo, Sunny Health & Fitness, Echelon, Peloton, NordicTrack, SOLE, Keiser, Stages, Technogym, Garmin and Concept2 on October 13, 2026, and the owner's manuals Johnson Health Tech posts on its parts sites for Schwinn, BowFlex and Horizon bikes. We copied each decibel figure in the maker's words, with whatever condition it gave, and found none with a cadence, a resistance level or a distance.
We then grouped the figures by kind, ceilings in one list and exact figures in another, ranked the ceilings lowest first, and chose picks across recumbent, spin and upright bikes. Where two bikes from one maker made the same claim, we picked the one with something more to offer a flat, such as the S29 Eco's self-powered design or the G1M Plus's screen. Where a store showed a sale, the card shows the regular price and the summary gives the sale price we saw.
We did not measure any of these exercise bikes, on a floor or at a microphone. Every decibel figure on this page is a maker's claim from its US product page, and the advice on floors, mats and leveling is quoted from Schwinn's, BowFlex's, Peloton's and NordicTrack's own documents.
