Horizon T101 Treadmill Review: Is the Used Version Worth It?
The Horizon T101 treadmill is $599 new and used ones list up to $1,125. Full specs, what breaks, whether it fits an apartment, and the price to pay.
The Horizon T101 treadmill sells new for $599, and used ones on our marketplace list anywhere from $570 up to $1,125. Read that again, because it is the entire problem with buying this machine secondhand. A large share of used T101 listings are priced at or above what a brand new one costs. So the honest answer to "is the used version worth it" depends almost entirely on what number is on the tag, and most of the numbers out there are wrong.
I move used treadmills for a living, and the T101 comes through our pickups more than almost any other budget folding machine. It is the treadmill people buy when they want something better than a big-box special without spending four figures. Here is what the Horizon T101 treadmill actually is, what breaks on used ones, whether it fits an apartment, and the price at which buying used finally makes sense.
Horizon T101 treadmill specs: what you are actually getting
The Horizon T101 treadmill is a walking and jogging machine, not a running machine. That is the single most important thing to understand before you buy one used.
| Spec | Horizon T101 | What it means |
|---|---|---|
| Motor | 2.5 CHP | Plenty for walking and jogging, thin for daily running |
| Belt size | 20" x 55" | Five inches shorter than the 60" runners want |
| Top speed | 10 mph | A 6:00 mile pace, more than most buyers use |
| Incline | 0 to 10%, powered | Real incline, adjustable from the console |
| User capacity | 300 lb | Standard for this price tier |
| Machine weight | 180 lb | Two-person move, not a one-person move |
| Folding | Hydraulic assist | The deck lowers itself instead of dropping |
| Warranty new | Lifetime frame and motor | Non-transferable, so used buyers get none of it |
That 55 inch belt is the spec that decides everything. Sixty inches is the number you want if you actually run, because a running stride is longer than a walking stride and you need the belt behind you. At 55 inches, anyone over about 6'0" running at pace will find the back of the deck. Walking, jogging, incline work, and interval sessions where you walk the recovery are all fine. Training for a half marathon on it is not.
The motor tells the same story. A 2.5 CHP motor moving a 180 pound person at 7 mph every day will run hot and wear out faster than the frame it is bolted to. At walking speeds it will outlive you. Buy the T101 for what it is and it is a good machine. Buy it as a cheap running treadmill and you will be disappointed twice, once by the belt and once by the motor.
What a used Horizon T101 treadmill costs in 2026
Do not pay more than $400 for a used Horizon T101 treadmill. Here is why that number is lower than you expected.
| Condition | What they list for | What it is actually worth |
|---|---|---|
| New, in store | $599 | $599, with a lifetime frame and motor warranty |
| Excellent, a few years old | $570 to $700 | $350 to $425 |
| Like new, low hours | $1,095 to $1,125 | $425 to $475 |
| Good, visible wear | $450 to $550 | $250 to $325 |
The gap between column two and column three is the whole story. Sellers price used T101s off the retail price they remember, and on a machine that only cost $599 new, there is not enough room underneath for a used listing to make sense at $700. You are paying more than new for a machine with hours on it and no warranty.
And the warranty piece is not a small thing. Horizon covers the frame and motor for the lifetime of the original owner, and that coverage does not transfer. So when you buy a used T101, you are buying the one component set that would have been covered forever, with zero coverage. On a $250 machine that is a fine trade. On a $700 machine it is a bad one.
My rule: under $400, a clean used T101 is a genuinely good buy. Between $400 and $550, only if it is nearly new and local. Over $550, buy it new and keep the warranty. The math is not close, and this is unusual. On most treadmills used is the obvious call, which we covered in our breakdown of what a used treadmill is actually worth.
Is there a Horizon T101 Connect?
No, and the confusion is worth clearing up because a lot of people search for it. Horizon does not sell a separate "T101 Connect" model. What exists instead are model-year generations of the same treadmill, sold as the T101-04, T101-05, and so on, with small console and feature revisions between them.
The connectivity people are thinking of is already on the T101. It has Bluetooth audio with built-in speakers, a device shelf for a tablet, and it speaks the standard FTMS protocol, which means third-party apps like Zwift and the Peloton app can read and in some cases control the machine. There is no subscription required for the treadmill to work, and nothing on the console is gated behind an account.
If you want a genuinely connected Horizon with a bigger deck and a stronger motor, that is the 7.0 AT and up, which used run roughly $675 to $1,175. Those are a different class of machine. Do not pay a connected-treadmill price for a T101 because a listing used the word Bluetooth.
What goes wrong on a used Horizon T101
Four things fail on this treadmill, and you can check all four in about five minutes.
- Deck cushioning breaks down. The T101 uses zoned cushioning under the deck, softer at the front, firmer at the push-off. When those elastomers compress with age the deck goes hard and flat, and you feel it in your shins before you see it. Walk the full length of the belt and feel for a dead spot.
- Belt wear and misalignment. Run your hand along the belt for glazing, fraying at the edges, or a hard shiny strip down the middle. Then run it at 3 mph for a minute and watch whether it tracks center or drifts toward one rail. Drift is adjustable. Glazing means a new belt.
- Incline motor. Run the incline from 0 to 10% and back down, twice. Listen for grinding, a stall partway up, or a motor that runs but does not move the deck. This is the most expensive common repair on the machine and the one sellers most often forget to mention.
- Console and key switch. Confirm the display lights fully, the speed and incline arrows respond, and the safety key kills the belt instantly. A console that boots but drops speed readings intermittently is on its way out.
The good news is the frame and motor rarely fail. Horizon builds its own motors, and on a machine used at walking speeds the motor is almost never the reason a T101 gets sold. It gets sold because someone stopped using it. That is the single best used-treadmill scenario there is: a machine with 40 hours on it that lived in a spare bedroom.
Ask the seller one question: how often did you actually use it? The honest answers are usually either "constantly for two years" or "about six times." You want the second one, and there are more of those than you would think.
Does the Horizon T101 fold and fit in an apartment?
Yes, and it is one of the better folding treadmills for a small space, with one real caveat.
The deck folds up vertically and the hydraulic assist means it lowers itself back down instead of slamming to the floor, which matters if you are the one folding it every day. Folded, it takes up a footprint a bit larger than a bath mat standing on end. It rolls on front transport wheels.
The caveat is the 180 pounds. That is not heavy for a treadmill, but it is heavy for a piece of furniture, and it is concentrated awkwardly. Getting one up a flight of stairs is a two person job with a proper strap or dolly, and the transport wheels are for flat floors only. Every "I'll just grab a friend" treadmill move I have heard about that went badly involved stairs.
For upstairs apartments, also think about noise below you. A treadmill on a second floor transmits impact through the joists no matter what deck cushioning it has. A rubber mat under it helps more than people expect. We go deeper on this in our guides to treadmills for apartments and folding treadmills for small spaces.
Horizon T101 vs Sole F63 vs ProForm: the better used buy
The Sole F63 is the better used treadmill. The Horizon T101 is the better new treadmill. That inversion is the whole comparison.
| Horizon T101 | Sole F63 | ProForm | |
|---|---|---|---|
| Typical used price | $570 to $1,125 | $570 to $1,375 | Around $920 median |
| New price | $599 | Roughly $1,000+ | Varies widely |
| Belt length | 55" | 60" | 55" to 60" |
| Motor | 2.5 CHP | 3.0 CHP | 2.5 to 3.0 CHP |
| Subscription pressure | None | None | Heavy |
| Used value | Poor above $450 | Strong | Depends on the model |
The F63 costs meaningfully more new, which means there is real room underneath it for a used discount. You get a longer deck, a stronger motor, and a machine that was built to be run on. A used F63 at $700 is a better purchase than a used T101 at $700 in every way that matters. We wrote up the used Sole F63 separately if you want the detail.
ProForm is the wildcard. The hardware is often fine and the pricing is all over the place, but many models push you toward a subscription for the programming, and older consoles age badly. Our guide to buying a used ProForm treadmill covers which ones are worth it. One note that surprises people: Horizon and Schwinn now sit under the same parent, Johnson Health Tech, which bought the BowFlex and Schwinn brands in April 2024. Horizon has been a Johnson brand all along, and it is the reason Horizon builds its own motors rather than sourcing them.
Should you buy a used Horizon T101 treadmill?
Here is the decision, in order.
- Under $400 and it passes the four checks: buy it. This is the machine at its best, a lightly used walking treadmill for less than half of new.
- $400 to $550 and nearly new: acceptable if it is local and you can see it run. You are trading the warranty for a few hundred dollars.
- Over $550: buy new instead. Same machine, zero hours, lifetime frame and motor coverage.
- You want to run, not walk: skip the T101 entirely and shop a used Sole F63 or another 60 inch deck.
- It lived in a garage: check the belt and deck hard. Humidity and treadmill decks do not get along.
- The incline will not sweep the full range: walk away, or price it as a flat treadmill.
The T101 is a good treadmill that is bad at being a used treadmill, purely because it was cheap to begin with. That is not a knock on the machine. It is a knock on the listings.
Frequently asked questions
Is the Horizon T101 good for running?
Not really. The 55 inch belt is five inches shorter than what runners need and the 2.5 CHP motor is sized for walking and jogging. It is an excellent walking and incline-walking treadmill and a mediocre running one.
What is a fair price for a used Horizon T101?
Under $400 for a clean unit. Between $400 and $475 for something genuinely like new. Above $550 you are better off buying new, because the machine only costs $599 and the lifetime frame and motor warranty does not transfer to you.
How long does a Horizon T101 last?
Ten years or more at walking speeds, less if it is running daily under a heavier user. The frame and motor outlast everything else. The deck cushioning and belt are the wear items and both are replaceable.
Can one person move a Horizon T101?
On flat ground with the transport wheels, yes. Up or down stairs, no. At 180 pounds with an awkward center of gravity it is a two person job, and folded does not mean light.
Does the Horizon T101 need a subscription?
No. Every function works from the console with no account and no monthly fee. The Bluetooth and FTMS support let you connect third-party apps if you want them, but nothing on the treadmill is locked behind a paywall.
Buying or selling one
If you have a treadmill in a spare room that you have not stepped on since February, you do not have to list it yourself and field messages from strangers. We handle the listing, and when it sells our drivers come to you, fold it, and carry it out. You get paid before it is off the property. Here is how it works, and our guide to selling a treadmill covers what yours is realistically worth first.
Buying instead? Every treadmill we list gets inspected before it goes out, gets delivered by our own drivers, and comes with a 60 day warranty. You pay when it is in your house and you have walked on it, not before. Start with our roundup of buying a used home treadmill and find one that fits the room you actually have.
