Spin Bike 16-Level Magnetic Resistance 12kg Flywheel Commercial Grade

The Lifespan Fitness SM-420 Spin Bike is a commercial-grade performance bike designed for serious home cyclists and small group training operators. The centrepiece is a 12kg commercial grade flywheel that delivers the kind of rotational inertia needed for smooth, high-torque sprint efforts — TrueSpin balanced to eliminate vibration at every RPM. Sixteen levels of seamless magnetic resistance adjust at the turn of a dial, simulating real road gradient transitions without the mechanical noise of friction-based systems.

The aluminium alloy pedals with toe clips and 3-piece forged steel crank deliver efficient power transfer from shoe to flywheel through every pedal stroke, and the racing PU leather seat with multi-axis adjustment means finding your perfect saddle position takes under two minutes. In-built hand pulse sensors in the adjustable handlebar give you heart rate feedback at a glance without needing a chest strap, and the large LCD display logs resistance, time, distance, and calories on a clean high-contrast screen. Transport wheels and floor levellers make it easy to reposition between sessions.

Backed by a lifetime of 5 years on the spin bike frame and a 12-month parts replacement warranty, the SM-420 is the kind of bike that earns its place in a dedicated garage gym or home training space — built to outlast the warranty period under daily use by multiple users.
