Durable, comfortable, and smooth are all qualities of the Spirit Fitness CU800 fitness bike. Easy adjustments, bright LED screens, a turbo cooling fan, high density foam seats, challenging programs, 40 levels of magnetic resistance, and a generator powered console are standard on both models. Indoor exercise bikes have been around for many decades. Their appeal and effectiveness have stood the test of time. Comfort, convenience, familiarity, enjoyment, and medical conditions are a few reasons this modality appeals to a large segment of the population. The entire C series expounds on two of these critical areas – comfort and convenience.
