This X4S exercise bike was developed through 3 years of design and over 2000 tests, focusing on ergonomics and kinematics to ensure optimal cycling performance. Constructed with 2mm thick commercial steel and a multi-triangle structure, the bike supports up to 330 lbs (150 kg) and offers a stable, long-lasting ride. It features a 4-way adjustable seat and handlebar to accommodate users with inseams from 28” to 37.4”. Adjustable steel toe-caged pedals and an easy-to-use resistance knob allow for customized workouts. The Bluetooth backlit monitor displays essential data such as time, speed, distance, Rpm, load (1%-100%), calories, and Bpm when connected to a heart rate band. It also syncs with third-party apps for virtual cycling classes or routes. The dual solid flywheels and belt drive system provide a smooth, nearly silent ride, while the 6-magnet resistance and leather brake pad ensure safety and efficiency during workouts. Includes a 30-day extended Kinomap subscription.
