Cardio equipment absorbs 35–45% of a gym’s total equipment budget, and it is the category where a wrong duty-class decision costs the most: in a commercial facility only professional-class machines under EN ISO 20957 (class S) are admissible, because domestic units fail within 12–24 months of club duty and their warranties are void outside their rated class. This guide compares treadmills, bikes, ellipticals, rowers and air machines by the criteria that actually separate brands — motor, frame, serviceability and total cost — with verified price anchors for 2026.
Duty class: the non-negotiable filter
Before comparing brands, verify three things on any shortlisted machine:
- the EN ISO 20957-1 declaration naming class S (professional/commercial use);
- a written warranty valid in commercial use — many “semi-pro” offers quietly exclude it (commercially, no “semi-professional” class exists in the standard: a machine is class S or it is domestic class H);
- the unit weight: a commercial treadmill weighs 150–200 kg; a light machine is a domestic machine regardless of the brochure.
Treadmills: the criteria that separate models
- Motor: AC (alternating current) of 3 hp continuous or more for club duty — AC motors run cooler and last 2–3 times longer than DC under continuous load.
- Running deck and belt: at least 150 × 50 cm, with a cushioning system and a belt rated for multi-hour daily duty; belts are consumables (200–500 EUR excluding VAT fitted, every 2–4 years).
- Console: LED consoles cost less and break less; touchscreen consoles drive member experience in premium clubs.
- Incline: 12–15% motorised incline widens programming — selection criteria in our commercial treadmill buying guide.
| Treadmill tier | Motor warranty (typical) | Indicative price (EUR excl. VAT) | Verified examples |
|---|---|---|---|
| Accessible professional | 3 years | 3,500–5,000 | — |
| Core club class | 5 years | 5,000–8,000 | Etenon V12 LED: 5,995 · Bodytone EVOT3 touchscreen: 5,832.75 |
| Premium connected | 7–10 years | 8,000–15,000 | — |
Bikes and ellipticals
On bikes, the split is resistance technology: magnetic (adjust by lever, cheaper, robust) versus electromagnetic (console-controlled watts, needed for programme-led training). Verified anchors from our range: the DV-PRO multimedia upright at 2,175 EUR excluding VAT, the Bodytone Nexion U80L (LED console) at 2,440 EUR excluding VAT and the Nexion U80T with 15.6-inch touchscreen at 3,790 EUR excluding VAT. On ellipticals, stride length is the first criterion — 50 cm+ for a natural gait — ahead of console features; the commercial Bodytone Evoe1+ is 8,660.40 EUR excluding VAT. For seated cardio serving older or deconditioned members, a commercial recumbent such as the Bodytone EVOR1+ (7,662.90 EUR excluding VAT) completes the park.
Rowers, air bikes and ski ergs
- Air rowers: the HIIT standard — robust, self-powered, minimal electronics. Xebex Air Rower 2.0 at 1,250 EUR excluding VAT, Air Rower 3.0 at 1,450 EUR excluding VAT.
- Air bikes: the highest work-per-euro machine on the floor — Xebex AirPlus from 1,050 EUR excluding VAT, Air Bike Power at 1,850 EUR excluding VAT. See our Xebex vs Assault Fitness comparison.
- Ski ergs: vertical pulling cardio, compact wall footprint — Xebex Ski Trainer at 1,550 EUR excluding VAT.
Composing the park by club format
| Format | Cardio units | Accessible budget (EUR excl. VAT) | Premium budget (EUR excl. VAT) |
|---|---|---|---|
| Studio / micro-gym 100 m² | 6–8 | 20,000–30,000 | 35,000–55,000 |
| Standard club 300 m² | 14–20 | 50,000–75,000 | 90,000–140,000 |
| Premium club 600 m² | 25–35 | 85,000–130,000 | 175,000–280,000 |
Split roughly 45% treadmills, 30% bikes/ellipticals, 25% HIIT machines for a generalist club, and shift toward air machines for functional concepts.
Choosing the brand: what actually matters
- Spare-parts availability and lead time — a machine down for six weeks costs more members than a cheaper purchase ever saved;
- Commercial-use warranty terms in writing;
- Service network in your country, with documented response times;
- Console ecosystem — only pay for connectivity your members will use;
- Price-to-durability — global premium brands (Technogym, Life Fitness, Precor) command 30–60% premiums over European challengers such as Bodytone and Etenon at comparable duty ratings; both routes are legitimate, but mixed parks should keep one brand per machine family to simplify servicing.
Budget strategy: new, refurbished or leased
Professionally refurbished cardio saves 30–50% with 6–12 month warranties — viable for phase-one openings if sourced from a specialist. Finance leasing spreads a 50,000 EUR park over 36–48 months, keeping cash for marketing. Whichever route, model the five-year picture: an all-inclusive maintenance contract runs 2,500–5,000 EUR excluding VAT per year for a standard club, and the full method is in our treadmill total cost of ownership guide. Preventive schedules — belts, lubrication, calibration — are detailed in the cardio maintenance schedule.
Frequently asked questions
How many treadmills does a 300 m² gym need?
Six to eight, as part of 14–20 total cardio units. The ratio rises for city-centre clubs with winter running demand and falls for functional-training concepts where air machines take over.
Can I use domestic treadmills in a commercial gym?
No. Beyond rapid failure, a domestic (class H) machine used commercially voids its warranty and exposes the operator’s liability after an incident — the standard’s usage classes exist precisely to prevent this.
What is the real lifespan of a commercial treadmill?
Seven to twelve years with preventive maintenance — typically 20,000–30,000 km on the original motor, with one or two belt changes along the way. Skipping maintenance halves this.
Should all cardio come from a single brand?
Not necessarily — but keep one brand per family (all treadmills alike, all bikes alike). Mixed fleets within a family multiply spare-part references and technician visits.
