Power your next cardiovascular exercise with the SF-B1913 Training Cycling Bike by Sunny Health and Fitness. Keep your feet secure by using the universal toe cages or by using SPD-compatible footwear. Tailor the bike by adjusting the 4-way adjustable bike seat and handlebars (leg inseam 29 inches to 39 inches). Take hold of the multi-grip handlebars to switch up your riding style and reduce fatigue during longer rides in one grip position. Grab the hand pulse sensors on the handlebars to monitor your heart rate for increased cardiovascular workout efficiency. Enjoy a smooth and quiet belt-drive mechanism that engages the hefty 44 lb flywheel. Designed with magnetic resistance, this indoor cycle bike can apply resistance precisely with its micro-adjustment knob or swiftly bring the flywheel to a complete stop by pressing on the knob. Use the on board performance monitor to track your speed, cadence, distance, calories, time, and pulse.
