MRB1 Indoor Exercise Bike with Cast-Iron Flywheel

Indoor cycling, minus the racket. This MRB1 Magnetic Resistance Exercise Bike pairs a quiet belt drive with a 13.2 lb precision cast-iron flywheel, which keeps momentum smooth and the ride feeling something like the road.

• 0–100% magnetic resistance: Light warm-ups and heavy climbs sit on the same dial, so you can control intensity minute by minute.
• Road-like momentum: The cast-iron flywheel holds speed steadily through endurance rides and HIIT intervals alike.
• Under 25 dB: Frictionless magnets and the belt drive keep things quiet enough for apartments, shared rooms, and workouts at 6 a.m. or 11 p.m.
• Fit to your frame: Seat and handlebars both adjust for different heights and postures, and the ergonomic build eases wrist and body strain over longer sessions.
• Steel base, handy extras: An industrial-grade triangular steel frame carries up to 300 lbs. Transport wheels, a bottle holder, an adjustable device mount, and Bluetooth app connectivity round it out.
