Exercise Bikes,[link widoczny dla zalogowanych]
Differing FunctionsExercise bikes are free-standing machines -- often with electronic gauges and resistance controls -- allowing cyclists to pedal away for miles without moving an inch,[link widoczny dla zalogowanych]. These often are found in gyms and health clubs as options for cardiovascular exercise,[link widoczny dla zalogowanych]. Bike trainers incorporate the same concept of stationary riding but allow cyclists to use their actual bicycles during the indoor workout,[link widoczny dla zalogowanych]. Trainers prop up the rear wheel of bikes and hold the cycles in one place for stationary riding,[link widoczny dla zalogowanych].
General TypesExercise bikes come in two general varieties: upright and recumbent. Upright bikes require an upright posture similar to sitting on a real bike,[link widoczny dla zalogowanych], with seats that raise or lower for proper height and leg adjustment. These tend to be noisy.
Magnetic trainers use a series of magnets that create tension on the resistance wheel,[link widoczny dla zalogowanych], simulating riding on inclined surfaces.
Bicycle trainers lack the electronic amenities of exercise bikes. Trainer users adjust tension wheels for simulating inclined surfaces by tightening knobs located near the trainer base and housing for the bicycle wheel. The top feature of trainers comes in the use of the actual cycles that riders use outside,[link widoczny dla zalogowanych], making it the perfect training tool in the offseason.
Comfort ConsiderationsCyclists with chronic back discomfort often choose the reclined features of recumbent bicycles for riding,[link widoczny dla zalogowanych], whether using stationary or road bikes. For upright stationary riding,[link widoczny dla zalogowanych], protecting knees becomes a main concern. Bike seat adjustments that are too low don't allow for full leg rotations,[link widoczny dla zalogowanych], and seats adjusted too high overextend the legs. Either extreme leads to exhausted,[link widoczny dla zalogowanych], sore or even injured knees. It should not be used as a substitute for professional medical advice,[link widoczny dla zalogowanych], diagnosis or treatment. LIVESTRONG is a registered trademark of the LIVESTRONG Foundation.
