Start a new in-home fitness routine with the SF-B1851 Synergy Pro Magnetic Indoor Cycling Bike. Ergonomically designed, this bike has rounded multi-grip handlebars and a 4-way adjustable seat that can help maintain your comfort and stability while you exercise. Cycling on an indoor bike is a low-impact exercise that can strengthen your cardiovascular performance and engage muscles in your arms, core, and legs.

  • INERTIA-READY FLYWHEEL: The large 40-pound flywheel is designed to store moving energy that keeps you pedaling consistently during your cycling workout. The onboard magnetic brakes can bring the wheel to a stop instantly.
  • BELT-DRIVE MECHANISM: This bike has a durable belt-drive mechanism that is smooth and consistent, allowing you to focus more on your performance while you’re on the bike.
  • MAGNETIC RESISTANCE: The integrated magnetic resistance puts you in full control of your workout intensity. It delivers consistent performance that makes your workout easy when you want it, hard when you need it.
  • PULSE-SENSING GRIPS: Monitor your cardiovascular performance with the built-in pulse-sensing grips so you can actively check your workout progress, displayed on the performance monitor.
  • DUMBBELL HOLDER: Use this cycling exercise bike in tandem with dumbbells (not included) to engage muscles in your upper body and core while you cycle. You can place them onto the built-in dumbbell holders when they are not in use (up to 20 lbs).
  • BUILT FOR COMFORT: Customize the bike to your height with the 4-way adjustable seat and 2-way adjustable handlebars. Maximize your cycling stability when you place your feet in the toe cages or on the clip-in compatible pedals.
  • WORKOUT ANALYSIS: Monitor your workout efficiency when you track your average, max speed, and cadence on the built-in performance monitor. Use the speed and cadence data to assess and analyze your general fitness progress or cycling performance.

  • 40-LB FLYWHEEL The swift 40-pound flywheel will make it easy to get your exercise cycling routine started, while also maintaining speed and consistency as you pedal. The cast-iron make prevents any issues with pulleys or loud sounds.
  • SILENT AND SWIFT RIDE Built with a modern near-silent belt-drive mechanism to give a smooth and consistent performance, removing any distractions as you work out no matter the time of day even when people are sleeping.
