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 clip-in compatible footwear. Tailor the bike by adjusting the 4-way adjustable bike seat and handlebars (leg inseam 29 inches to 39 inches). Enjoy a smooth and quiet belt-drive mechanism that engages the hefty 44-pound 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. Ride confidently and intensely thanks to the heavy-duty hexagonal steel tube frame, which can support up to 300 lbs. After your workout, use the transportation wheels to move the bike from room to room for easy storage.
