The S1 Indoor Bike can help you work out a much larger set of muscle groups as opposed to standard indoor cycles, due to the larger variety of positions you can assume. There are five standard positions in spinning: seated flat, standing flat, seated climb, standing climb and jumps. The emphasis of spinning is to replicate road bikes movements as closely as possible, at the same time working key muscles in the legs, core, back and upper body for a more complete workout. To aid this, the S1 features a substantial 14kg flywheel, providing the rider with a much smoother ride compared to standard exercise bikes. The 32 levels of electronically controlled resistance also provide that extra challenge. The new and innovative self-powered generator system means that you can take your workout anywhere without the need to worry about a power source. Your motion powers the hand pulse sensor and the versatile computer display which shows a wide range of functions including speed, time, distance and your calories burnt to stay on top of your workout.Spin bikes can help maximise your fat burning ability and at the same time offer a low impact workout. Motion in different areas of the body including the shoulders, back and legs help further improve your fat burning potential in less time.Specification:*Brake System: New generator power system*Levels Of Resistance: 32*Flywheel Weight (Kg): 14 Kg*Flywheel Inertia (Kg): 22.1 Kg*Pedal Spec: Balanced pedal w/adjustable strap*Gear Ratio: 210:50*Crank Type: 3 pieces*Handlebar Spec: Vertical adjustment*Upright Tube Type: 30x70mm Oval Tube*Stabilizer Tube Type: 50x98mm Special-Shaped Tube*Speaker Spec: No*Seat Adjustment: Vertical / Horizontal*Seat Height: 77 - 92 cm*Saddle Type: SP04 Saddle
