The S500 indoor cycling spin bike sits in the sweet spot: a 15 kg flywheel and a 150 kg rating, at a price that does not need a business case. It is the bike most serious home riders should be looking at.
The 15kg flywheel
Fifteen kilograms of flywheel gives the pedal stroke real momentum, which is what makes an indoor bike feel like riding rather than pushing. More resistance is available for the same effort, so you burn calories more efficiently at any given pace.
Note that it is a free wheel: when you stop pedalling, the flywheel keeps turning for a moment and takes your feet with it. That is normal on spin bikes, and it is why the emergency brake matters.

Magnetic resistance
Resistance is magnetically controlled, which means there is no direct metal-on-metal contact. Therefore nothing wears down, the ride stays silent, and the bike lasts considerably longer than a friction-pad system.
An emergency braking system stops the flywheel immediately when you press the resistance bar, which is the safety feature every free-wheel bike needs.
Fit and adjustment
Both the seat and the handlebar adjust to suit different heights, and the padded seat is built for time in the saddle rather than five minutes of it. Between the two adjustments you can set up for flat-road riding, standing sprints or a seated climb.
Front foot tube wheels let you move the bike aside afterwards, and a phone and drink holder mean a long ride comes with something to watch and something to drink.

Common questions
Is the S500 indoor cycling spin bike quiet?
Yes. Magnetic resistance means nothing rubs, so there is no friction noise at all.
What is the weight capacity?
150 kg.
Does it read heart rate?
Yes, through pulse sensors built into the handlebars.
Can I stop pedalling suddenly?
The flywheel is a free wheel, so it keeps turning briefly. Press the resistance bar to brake it immediately.
