This is the first decision and it determines everything else. Both machines deliver the cardiovascular work the activity guidelines call for. They differ on almost every practical axis around that.

Treadmill versus bike across the axes that actually decide it

The bone-loading point, which is the real argument for a treadmill

Cycling is non-weight-bearing. Walking and running are. Weight-bearing exercise stimulates bone maintenance in a way cycling does not, which is why the NIH's bone health guidance lists walking and jogging among the recommended activities and cycling among the non-weight-bearing ones.

For a younger buyer this rarely drives the decision. For anyone concerned about bone density — post-menopausal women in particular — it is a genuine reason to prefer a treadmill, or to pair a bike with walking and strength work.

The noise point, which is the real argument for a bike

Running transmits impact through the floor structure into the ceiling below. No amount of motor quietness changes that. In an apartment above another household, the honest answer is a bike — or a treadmill used only for walking, on a dense rubber mat. See treadmills for apartments.

Decide with these four questions

Is your budget under $700? Buy the bike. The treadmill at that price is a walking machine.
Do you live above someone? Buy the bike, unless you will only walk.
Do you have joint problems? Buy the bike.
Do you actually want to run, or is bone loading a specific concern? Buy the treadmill.

Horizon 7.0 AT

Horizon Fitness

9.0/10

3.0 CHP, a 20″ × 60″ deck and QuickDial controls that change speed and incline in one motion — the best machine here for anyone whose workout changes every 60 seconds.

Published specifications
Motor	3.0 CHP
Running surface	20″ × 60″
Incline	0–15%
Top speed	12 mph
Weight capacity	325 lb
Console	7.25″ high-contrast LCD, 8 preset programs
Warranty	Lifetime frame + motor, 3 yr parts, 1 yr labor
Subscription	No subscription

Horizon sells no subscription for this machine. The Bluetooth broadcast works with whatever third-party app you already use, and the console is fully functional with none.

Specifications per Horizon Fitness published specifications.

What it does well

QuickDial rollers are the single best interval-training control on a sub-$1,000 treadmill
Streams to Zwift, Peloton and Nike Run Club over Bluetooth — apps you choose, not one you are forced into
Lifetime frame and motor cover with three years of parts

Where it falls short

No touchscreen at a price where iFIT machines ship one
Folding mechanism is stiffer than Sole's hydraulic assist
Deck cushioning is firmer than the T202's three-zone system

Motor: 9.0
Deck: 9.0
Incline: 9.0

#2 · A Peloton ride feel with no Peloton bill

$795.99Amazon

#ad How we are funded · Price as of October 5, 2026

Schwinn IC4

Schwinn Fitness

9.0/10

A 40 lb flywheel with 100 levels of magnetic resistance and open Bluetooth — it rides like the subscription bikes and connects to whichever app you choose, including none.

Published specifications
Flywheel	40 lb
Resistance	100-level magnetic
Weight capacity	330 lb
Console	Backlit color LCD: HR, speed, time, distance, calories, RPM
App support	JRNY, Peloton, Zwift via Bluetooth
Pedals	Dual-sided: toe cage and SPD
Subscription	No subscription

Nothing is gated. JRNY is optional, and the bike's Bluetooth broadcast works with Peloton, Zwift or no app at all — every console metric is on the bike itself.

Specifications per Schwinn Fitness published specifications.

What it does well

100 discrete magnetic levels mean you can repeat a workout exactly — friction bikes cannot
Broadcasts cadence and speed over Bluetooth to any app, so you are not locked to one ecosystem
Dual-sided pedals work with trainers or cycling shoes out of the box
330 lb capacity is above the class norm

Where it falls short

No screen — you supply a tablet, which the included holder expects
Resistance is a knob, not an app-controlled servo, so classes cannot auto-adjust it
The most expensive bike here that is not a studio machine

Ride: 9.0
Fit: 9.0
Resistance: 10.0
Build: 9.0

#3 · Running on a four-figure budget

Sole F63

Sole Fitness

8.8/10

A 3.0 CHP motor and a full 20″ × 60″ deck at a price where most machines give you one or the other — and the console works forever with no account.

Published specifications
Motor	3.0 CHP
Running surface	20″ × 60″
Incline	0–15%
Top speed	12 mph
Weight capacity	325 lb
Folds	Yes, hydraulic assist
Warranty	Lifetime frame + motor, 3 yr parts, 1 yr labor
Subscription	No subscription

Nothing is gated. The SOLE+ app is free and entirely optional; incline, speed and every console metric work with the machine unplugged from the internet.

Specifications per Sole Fitness published specifications.

What it does well

3.0 CHP is genuine running-duty power, not a peak-horsepower marketing number
Full 60″ belt — long enough for a 6-foot stride at speed
Lifetime frame and motor warranty at well under the price where that usually starts
The console is a plain LCD: every readout works with no app, no login, no fee

Where it falls short

253 lb assembled — a two-person move, and it does not go upstairs easily
The 6.5″ LCD is basic next to touchscreen rivals at the same money
82″ × 35″ footprint unfolded is a real chunk of a spare room

Schwinn 230 Recumbent Bike

Schwinn Fitness

8.0/10

16 magnetic resistance levels, a 300 lb rating and a proper step-through frame from a brand that still sells parts — the safe recumbent choice.

Machine weight	80 lb
Console	5.5″ LCD with Bluetooth

Specifications per Schwinn Fitness published specifications.

What it does well

Numbered magnetic levels, so sessions are repeatable
Step-through frame with a low entry height
Bluetooth to the Schwinn and third-party apps — no plan required

Where it falls short

64″ long is a serious footprint for a bike
300 lb capacity is beaten by cheaper no-name recumbents claiming 400 lb
Seat is comfortable but not adjustable for backrest angle

Ride: 8.0

Frequently asked questions

Which burns more calories, a treadmill or an exercise bike?

At the same perceived effort and duration they are broadly comparable. Running at a hard pace can burn more per minute than moderate cycling, but a hard bike interval beats a gentle walk. Energy expenditure follows effort and duration, not machine type — so the one you will use for longer wins.

Is a treadmill or bike better for bad knees?

A bike, clearly. Cycling is non-impact and moves the joint through a controlled arc, which is why rehabilitation programs use stationary bikes so heavily. A recumbent is gentler still. If a knee is the limiting factor, buy the bike.

Is a treadmill or bike better for an apartment?

A bike, unless you will only ever walk. Running transmits impact through the floor structure into the unit below regardless of how quiet the motor is. A bike transmits almost nothing. A walking pad on a dense rubber mat is the treadmill compromise.

Do exercise bikes help bone density?

Much less than walking or running does, because cycling is non-weight-bearing. The NIH's bone health guidance lists weight-bearing activities such as walking and jogging as the ones that stimulate bone. If bone density is a concern, pair a bike with walking and resistance training, or choose the treadmill.

Which lasts longer, a treadmill or an exercise bike?

A bike, substantially. There is no motor, no long deck taking repeated impact, and far fewer wear parts. A well-built magnetic bike can last fifteen years with essentially no maintenance; a treadmill in regular running use is doing well to reach ten.
