How is an upright bike and a spin bike different from each other?
An upright bike, also referred to as a stationary bike, have fixed resistance levels, a computer display console, a broader and more comfy seat as compared to spin bikes, and heart rate sensors. We recommend this bike for seated workouts.
A spin bike, also known as indoor cycling bikes, are more similar to exercise bikes as they have multiple grip bars and a racing saddle. It is ideal for both standing and seated workouts.
