The 4000 meter BikeErg is the bike's 2k row: a 6-9 minute threshold test where pacing errors are fatal and the middle half decides everything. Because the BikeErg spares the grip and back, it isolates pure leg endurance and aerobic power more cleanly than any other erg - which also means there's nothing to blame. It's the standard distance for comparing BikeErg fitness and the anchor number for pacing bike calories in workouts.

Race it like a 2k row: controlled first 1000 at goal watts, iron discipline through 1000-3000 (this is the entire test), then rise over the last 800. Pick a target wattage and defend it - watts drop silently on a bike when focus drifts. Cadence 85-100 rpm, damper where you'd do intervals, hands relaxed. The legs will burn in isolation without the whole-body distress of rowing; it's a different, more local pain - expect it and keep circling. Even 500 m splits are the win condition.
Beginner: 4000 m at steady conversational effort, or 4 x 1000 m with 1 min rest holding one split - consistency before intensity.
