Keiser M3i Indoor Bike
The buy-once-for-decades studio bike: whisper-quiet magnetic resistance across 24 gears, a rear-mounted flywheel outside the sweat zone, zero-maintenance Poly-V belt, and EN 957-10-certified power accuracy. Runs on 2 AA batteries — no cord. US-built. The free Keiser app is optional; the M Connect display works standalone.

Questions & answers
