Spirit Fitness Bikes

It comes down to riding position and training goal. Upright bikes give a compact, facility-standard cardio ride. Recumbent bikes trade a smaller footprint for back support and an easy step-through mount. Indoor spin bikes mimic road-cycling geometry for class-style interval training. Air bikes add a full-body handlebar for unlimited, effort-based resistance.

Upright (CU-series) puts you in a traditional gym-bike position — this is the format most facilities default to, with induction-brake resistance and console-driven programs. Recumbent (CR-series) uses a step-through frame and a reclined seat with back support, the easiest bike to mount and dismount, popular with rehab, PT, and lower-impact home use. Indoor spin (CIC-series) puts the saddle and handlebars in an adjustable road-cycling position for standing intervals and class-style workouts, with a magnetic resistance knob instead of a friction brake. Air (AB-series) adds moving handlebars for a full upper-and-lower-body workout, with resistance that scales automatically with effort — no dial to set.

All four are self-generating (no outlet required) and available at Commercial grade; upright and recumbent also come in Light Commercial and Residential tiers for a lighter-use home gym. Tell us your space and training goal and we'll point you at the right format.

The recumbent (CR-series) is the lowest-impact option — a reclined, supported seat and a step-through frame that doesn't require swinging a leg over a top tube. The upright is still a seated, low-impact ride; spin and air let you set your own intensity but ask more of the joints during standing intervals.

Spirit's recumbent bikes are built with accessibility in mind: a step-through frame means you don't have to mount over a center bar, and the seat is a fully adjustable molded-foam design with back support, rated for a 450 lb max user weight. That combination is why recumbent bikes are the common choice for rehab, PT, and lower-impact home use.

The upright bike is also a seated, joint-friendly ride, just without the reclined back support. Spin and air bikes are higher-intensity by design — spin puts you in a forward-leaning cycling stance for standing intervals, and air's resistance scales with how hard you push, so both ask more of the joints during hard efforts. None of the four are high-impact in the way running is; the difference is seated support, not impact category.

Geometry and resistance. The spin bike (CIC850) puts the saddle and handlebars in an adjustable, forward-leaning road-cycling position with a magnetic resistance knob — built for standing intervals. The upright bike (CU900) keeps a traditional, more vertical gym-bike seated position with an induction brake and console-driven programs.

The CIC850 indoor spin cycle fits a 28.4″–41.1″ user inseam range with pop-pin saddle and handlebar adjustment, and its 37 lb perimeter-weighted flywheel runs through 100 levels of magnetic resistance set from a wireless smart knob — no brake pad touching the flywheel, so resistance stays smooth with nothing to wear out. It's built for class-style, standing-interval training.

The CU900 upright bike uses a 30 lb flywheel through an induction brake with 40 resistance levels and 10 built-in workout programs (manual, hill, interval, HIIT, and fitness test among them) run from the console — a seated, guided-workout experience rather than a stand-and-sprint one.

Upright, recumbent, and spin bikes use induction or magnetic resistance — no friction brake pad touching the flywheel, so they run quiet and consistent at any level. The air bike is the exception: resistance comes from air moving through the fan blades, so its sound rises and falls with how hard you're pedaling.

The CU900, CR900, and CIC850 all generate resistance electromagnetically — an induction brake on the upright and recumbent, a magnetic knob on the spin bike — with no brake pad ever contacting the flywheel. That means no friction noise and no wear-driven volume creep over time, which matters for a shared wall, an apartment amenity room, or a hotel fitness room.

The AB950 air bike works differently by design: its 27″ fan-bladed flywheel is what generates resistance, so the harder you pedal, the more air moves and the louder it gets. That's true of every air bike on the market, not a Spirit-specific trait — if a consistently quiet machine matters most, the upright, recumbent, or spin bike is the better fit.

Warranty structure varies by bike TYPE — it doesn't blend into one number across the lineup. Upright and recumbent bikes share a 3-tier structure (10-year frame at Commercial, Lifetime frame at Light Commercial/Residential). The spin bike has its own 3-tier structure (10/15/Lifetime-year frame depending on install setting). The air bike carries a single Commercial-only tier: 5-year frame, the shortest of the four, reflecting its simpler mechanical design.

Upright & recumbent (CU/CR-series): Commercial tier is 10-year frame, 5-year brake, 3-year parts and labor, 6-month wear items; Light Commercial and Residential both step up to a Lifetime frame with a shorter 2-year labor window. Indoor spin (CIC850): frame coverage depends on where it's installed — Lifetime at home, 15 years in a non-dues facility, 10 years in a dues-paying gym — with parts covered 3 years and labor 1 year across every tier. Air bike (AB950) is the outlier: it carries only ONE tier regardless of setting — 5-year frame, 2-year console and mechanical parts, 1-year labor — genuinely shorter coverage than the other three formats, which is a fair trade-off given its simpler build (no adjustable seat electronics, no console-driven resistance).

Whichever bike you're comparing, the exact tier table is on that product's own page. If warranty length matters more than format, ask us before you order and we'll steer you to the strongest-covered option.

No — every Spirit bike in this lineup (upright, recumbent, spin, and air) is 100% self-generating. Your own pedaling powers the console and cooling fan, so there's no outlet requirement and no batteries to replace on the drive system.

This is a shared trait across the whole Spirit bike range, not just one model: the CU900, CR900, CIC850, and AB950 all generate their own electricity from pedaling, so placement isn't limited by outlet access — put the bike anywhere in a room, a hallway alcove, or a facility floor plan without running new wiring. (Some consoles use small AAA batteries for the display electronics specifically, separate from the drive system — check the individual product page if that distinction matters for your setup.)

It varies by format — recumbent needs the most length, upright and air are the most compact. As a planning range: upright about 48″L × 25″W, recumbent about 67″L × 29″W (the largest footprint of the four), spin about 58.5″L × 22″W, and air about 47.5″L × 28″W. Exact dimensions are on each product page.

Every Spirit bike publishes a precise set-up footprint. The recumbent's step-through frame and reclined seat give it the longest footprint of the four formats at roughly 67″L × 29″W × 49″H — worth planning for if floor space is tight. The upright (48″L × 25″W × 55″H) and air bike (47.5″L × 28″W × 54″H) are the most compact of the four, and the spin bike (58.5″L × 22″W × 53.5″H) is narrow but a bit longer.

Beyond the bike itself, plan for rider access space to mount, dismount, and (on spin/air) stand during intervals. Send us your room dimensions when you request a quote and we'll confirm which formats actually fit.

Yes — multi-unit pricing with freight included, quoted within one business day. Tell us the formats and quantities (or just describe the room and who'll use it) and a Commercial Fitness Advisor prices the package and flags anything the install needs.

Outfitting a cardio row — a hotel fitness room, an apartment amenity room, a corporate gym, or a full facility floor — shouldn't be priced bike by bike, so bulk quoting is the default path here. Send a model list or describe your space and member mix, and we'll return multi-unit pricing with freight included within one business day.

The quote comes from a Commercial Fitness Advisor, not a ticket queue, and covers the details that matter later: delivery path (dock, stairs, liftgate), assembly, and matching each bike's max user weight and warranty tier to your actual usage. Our price-match guarantee applies to facility quotes too.
