Mid-drive details that matter before frame tooling begins

Each engineering stream connects mechanical packaging, electrical limits, display logic and aftersales diagnostics so an OEM program can move from ride sample to production freeze without scattered assumptions.

Performance Line CX motor housing

Performance Line torque mapping

Support modes are tuned around cadence, pedal force and wheel-speed data, giving trekking and eMTB programs a controlled 85 Nm response envelope without forcing every frame builder into the same ride feel.

  • L10 bearing review for loaded commuter duty
  • Cadence input validation before firmware freeze
  • Frame-interface tolerance notes for motor mounts
PowerTube battery integration

Battery and harness envelopes

PowerTube packaging choices are reviewed with removal direction, thermal clearance, cable bend radius and transport documentation in view, reducing redesign risk after the first painted frames arrive.

  • IEC 62133 battery documentation pathway
  • Serviceable connector access for dealers
  • 36 V pack integration and charger compatibility notes
Kiox display diagnostic workflow

Connected display and app workflow

Kiox and Flow app touchpoints are planned as service interfaces, not decoration. Dealers can read faults, update firmware and guide riders with consistent system information across markets.

  • Firmware update flow for dealer service desks
  • Display language planning for EN / DE / ES / ZH
  • Diagnostic notes for warranty triage
Applications

Segments that need a repeatable motor ecosystem

From high-cadence urban bikes to cargo fleets, the system is specified around load, service access, display behavior and regional compliance rather than a single headline wattage number.

"The strongest eBike motor program is not only the peak torque figure. It is the repeatability of packaging data, diagnostic behavior and field support from pilot build to dealer handover."
