Backed by over 30 years of innovation and trusted by millions of families worldwide, the JOROTO X4S Indoor Exercise Bike represents the next generation of professional-grade home cycling. Engineered with over 100 design refinements and 2,000 tests, this bike combines precision, durability, and smart technology to bring the spin studio into your living room.
With a dual flywheel system, 6-magnet resistance, and a silent belt drive, the X4S delivers a smooth, whisper-quiet ride that’s powerful yet low-maintenance. Its commercial-grade steel frame supports up to 330lbs (150kg), with a stable triangular structure and widened stabilisers that keep every ride rock-solid, even during standing climbs or sprints.
The own-developed Bluetooth backlit LCD monitor shows time, distance, speed, RPM, calories, resistance levels (1%–100%), and heart rate when connected to a wearable device. Plus, it syncs with 3rd-party fitness apps like Kinomap, allowing you to track progress, ride real-world routes, or join interactive classes.
The fully adjustable handlebars and seat accommodate riders from 28″ to 37.4″ inseam (approx. 140–193cm / 4’6”–6’3”), making it suitable for the entire family. With toe-caged pedals, emergency stop safety, and dual device holders, the X4S ensures comfort, control, and convenience with every session.
