Condition Report
The indoor exercise bike is in very good operational pre-owned estate condition. The chain drive drivetrain tracks smooth and silent, and the heavy chrome flywheel spins completely straight without wobbling. The friction pad, emergency stop lever, and resistance micro-knob operate perfectly. The padded black, silver, and red racing seat is clean with no splits or cracking. The foam non-slip coating on the multi-grip handlebars is fully intact across the entire surface layout.
