Horizon 5.0R support in QZ: JFBK5.0R resistance table added

QZ now has model-specific support for the Horizon 5.0R recumbent bike through the exact Bluetooth name JFBK5.0R. Merged public PR #4759 adds a dedicated ERG calibration table while reusing QZ’s existing FTMS indoor-bike path.

This is code-level merged-master evidence, not a claim that every store build already contains the change. Use a QZ build that includes PR #4759 / commit 6543e925 when testing this behavior.

What the Horizon 5.0R change adds

Bluetooth name JFBK5.0R
Connection path Existing QZ FTMS indoor-bike path
Resistance handling Model-specific default ERG calibration table
Cadence/resistance band 5 rpm quantization for the Horizon 5.0R table
Evidence boundary Merged repository code and tests; field behavior can vary by firmware and build

Setup notes

  1. Install a QZ build containing the merged Horizon 5.0R support.
  2. Turn on the bike and allow the Bluetooth name JFBK5.0R to be discovered.
  3. Use QZ’s FTMS bike workflow and pair QZ’s virtual device with your training app as needed.
  4. Check resistance behavior with your own bike and firmware; the calibration table is intended to improve ERG mapping, not guarantee identical results on every unit.

QZ integrations

Depending on device, platform and settings, QZ can bridge equipment to Zwift, MyWhoosh, ROUVY and Peloton-style workflows, and can support Apple Health / HealthKit, Garmin Connect, Strava and Google Health / Health Connect. FTMS devices commonly provide metrics such as power and cadence through the standard Indoor Bike Data characteristic, while control availability depends on the equipment.
