Self-Powered Performance. Commercial-Grade Construction. Smooth, Comfortable Ride. The Spirit CU900 Upright Bike is engineered for serious cardio training — whether that’s in a demanding commercial environment (gyms, rehab centers, corporate fitness rooms) or a robust home gym. Its self-generating design means no cords or outlets are needed, so the bike can be placed virtually anywhere. A 30 lb flywheel, heavy-duty crank axle with roller bearings, and an extra-wide 8-groove poly-V belt with spring-loaded idler combine for a smooth, quiet, and stable ride. The CU900 offers 40 levels of induction resistance — from gentle warm-up to challenging intervals — giving users a wide range of workout intensity. A fully adjustable comfort-molded seat (up/down) and ratcheting pedals with 2° inversion ensure ergonomic positioning and joint-friendly pedaling. Fixed handlebars with hand-pulse sensors, front transport wheels, and a compact footprint add to its practical usability. Built to withstand frequent use, the CU900 is a reliable upright bike that delivers consistent performance and low maintenance — a smart choice for facilities needing durability or homeowners seeking long-term value. Why the Spirit CU900 Is a Top Upright Bike Choice Self-Powered, Cordless Convenience The generator-powered mechanism eliminates cord clutter — great for flexible placement and minimal setup. Durable, Low-Maintenance Belt Drive System An 8-groove poly-V belt with spring-loaded idler and heavy-duty roller bearings reduce tension and wear, giving a smooth, consistent ride over years of use.
