MSeries

The companion app for Keiser M Series bikes, on iOS and Android.

Latest Release

v4.5.4

June 8, 2026

Overview

This update fixes how the app reads gears from M3i and M3i-Studio bikes running newer firmware, so your gear shows up during rides and in guided sessions.

Fixed

  • Gear readings on newer bike firmware — On some bikes with newer firmware, the app could miss your current gear. It now reads it and saves it with your workout.
  • Full gear range on M3i-Studio bikes — The app now recognizes 72-gear M3i-Studio bikes from their firmware, so gear targets in guided sessions cover all 72 gears.
