Start a new in-home fitness routine with the Sunny SF-B1851 Pro Indoor Cycling Bike. The Synergy Pro bike is one of the most advanced Sunny indoor exercise bikes. Ergonomically designed, this bike has a rounded multi-grip handlebar and 4-way adjustable seat that can help maintain your comfort and stability while you exercise.
The highlight of the SF-B1851 Synergy Pro bike is its exclusive innovative patented flywheel design based on Sunny’s years of experience and research. The 40 lbs (18.1 kg) flywheel adds additional momentum and smoothness when compared to standard flywheels.
The Sunny SF-B1851 Pro indoor cycling bike uses a belt drive magnetic resistance system that works perfectly with Sunny’s flywheel, making the ride remarkably smooth and quiet. Twist the resistance knob to increase or decrease the resistance to keep your riding workout challenging and effective.
Monitor your workout efficiency by tracking your average and max speed and cadence on the SF-B1851 fitness monitor. Then, use the speed and cadence data to assess and analyze your general fitness progress or cycling performance. Cycling on an indoor bike is a low-impact exercise that can strengthen cardiovascular performance and engage muscles in your arms, core, and legs.
