Treadmill buying guide: what to look for
The eight specs that decide a treadmill, in order, with the thresholds for each.
Specification guides and ownership
What each spec means, how much of it you need, and how to keep a machine running. The reference layer behind every ranking.

Every ranking on this site applies a set of thresholds — 3.0 CHP for running, 60 inches of deck above 5'8″, 30 to 40 lb of flywheel, 50 to 100 lb of capacity margin. These guides are where those thresholds come from and why they are set where they are. This is the editorial surface of the site: there is no separate blog, deliberately, because a parallel blog would duplicate guide intent and produce thin posts.
Start with the buying guides
- [Treadmill buying guide](/guides/treadmill-buying-guide) — the eight specs that decide a treadmill, in order of how much they matter.
- [Exercise bike buying guide](/guides/exercise-bike-buying-guide) — three decisions: format, resistance type, fit range.
- [Air bike buying guide](/guides/air-bike-buying-guide) — why fan resistance behaves completely differently from everything else.
Treadmill specification guides
| Guide | The question it answers |
|---|---|
| Motor and horsepower | CHP versus peak HP, and how much you need |
| Deck and belt size | How long a belt your height and pace require |
| Incline explained | What each gradient does and how to build to 12% |
| Deck cushioning | What cushioning does, and why softer is not better |
| Weight capacity | Static ratings versus dynamic loads, and margin |
Bike specification guides
| Guide | The question it answers |
|---|---|
| Flywheel weight | What it does, where the range ends, why position beats mass |
| Resistance types | Magnetic, friction and air compared on ownership |
| Drive systems | Belt versus chain, and what it does not affect |
Ownership and practicalities
- [Treadmill maintenance](/guides/treadmill-maintenance) — four tasks, a realistic schedule, and the lubrication mistake that kills motors.
- [How long do treadmills last](/guides/how-long-do-treadmills-last) — what fails, in what order, and what changes the odds.
- [Treadmill troubleshooting](/guides/treadmill-troubleshooting) — slipping, drift, noises, burning smells and when to stop.
- [Apartment noise](/guides/apartment-noise) — airborne versus structure-borne, and the isolation stack that works.
- [Space planning](/guides/space-planning-and-folded-footprint) — the clearances nobody mentions before you order.
Money
- [Subscription costs explained](/guides/subscription-costs-explained) — the three tiers, the TCO formula, and the four questions to ask.
- [Is a cheap treadmill worth it?](/guides/is-a-cheap-treadmill-worth-it) — yes, if you buy it for what it is. The mismatch that causes the disappointment.
Two guides carry no product picks, on purpose
Treadmill troubleshooting is safety content — if your machine smells of burning, you need a diagnosis, not a buy button. Treadmill maintenance carries only the machines it actually discusses. Bolting a tenuous product onto trust content is worse than an empty page, and we would rather say so than quietly monetize everything.

What each gradient feels like, how to build to 12%, and why you must not hold the rails.
Guide
Treadmill deck cushioning explained
How cushioning works, why variable-zone is the right design, and why softer is not better.

Frequently asked questions
What is CHP on a treadmill?
Continuous horsepower — what the motor sustains indefinitely under load. It is the only motor figure that predicts durability, and it is typically a third to a half of the peak horsepower figure that budget listings advertise for the same motor.
What treadmill specs actually matter?
Continuous horsepower, deck length, weight capacity with margin, incline range, and warranty depth — roughly in that order. Peak horsepower, preset program count, top speeds above 12 mph and screen size can be ignored.
What exercise bike specs matter most?
Format first, then resistance type, then fit adjustment range. Flywheel weight matters within a narrow band on spin bikes and barely at all on recumbents. Frame mass matters enormously and appears in no spec sheet — use shipping weight as the proxy.
How often should I maintain my treadmill?
Wipe it down every session, check belt tension monthly, check and lubricate the deck every three months or as your manual specifies, vacuum around the motor every three to six months, and check all bolts twice a year. Deck lubrication is by far the most important of these.
Does Belt & Bike have a blog?
No, deliberately. These guides are the editorial surface of the site. A parallel blog would duplicate guide intent and produce thin posts, which is exactly the kind of filler we are trying not to publish. New editorial content goes here.
