Sunny Health & Fitness Magnetic Belt Drive Indoor Cycling Bike, SF-B1805 - Black
The Sunny Health & Fitness SF-B1805 Magnetic Belt Drive Indoor Cycling Bike combines a magnetic resistance system with a genuine 44 lb flywheel for a smooth, stable ride. A precision-balanced chrome flywheel delivers consistent momentum and reduced vibration, while micro-adjustable magnetic resistance lets you fine-tune intensity to simulate flat roads, hills, or sprints without any chain noise or maintenance from the belt-driven mechanism.
A 4-way adjustable seat and handlebars genuinely fit inseams from 28" to 38", and steel pedals with adjustable toe cage straps help keep feet secure during intense sessions. An integrated tablet holder sits between the handlebars for streaming your own workouts or playlists, and a durable powder-coated steel frame supports up to 300 lbs, complete with an emergency stop brake, water bottle holder, and transport wheels.
