Bosch eBike Diagnostics

Professional Diagnostics for Bosch eBike Systems

I diagnose motors, batteries, and electronics on Bosch‑powered e‑bikes. I can read logs, run tests, clear error codes (incl. speed tampering), and provide detailed health reports.

See what I check Supported systems

What I can do

  • Full system scan of drive unit, battery, display/remote, sensors & charger.
  • Read live data (voltage, temperature, cycles), create a printable report.
  • Clear error codes including speed manipulation/tampering warnings after issues are fixed.
  • Calibrate & test: speed sensor / magnet alignment, torque & cadence readings, battery diagnostics.

Important limitations

  • No firmware updates — Bosch download servers are unavailable from my setup, so I do not perform firmware flashing.
  • Smart System (newer bikes) often needs DiagnosticTool 3.x. I can still run basic read‑outs where possible, but some functions are restricted.

Components I diagnose

If it’s part of the Bosch eBike System, I check it. Here’s what most customers ask about:

Drive Units (Motors)

  • Active Line & Active Line Plus
  • Performance Line & Performance Line CX
  • Cargo Line
  • (Legacy) Classic+

Batteries & Charging

  • PowerPack (300/400/500)
  • PowerTube (400/500/625)
  • Chargers: Compact / Standard / Fast

Displays & Remotes

  • Purion, Intuvia
  • Kiox, Nyon
  • (Smart System) LED Remote, System Controller, Kiox 300 — basic read‑outs only

Sensors & Extras

  • Speed sensor & magnet alignment
  • Cadence/Torque sensors
  • Lighting circuit
  • eShift interfaces & ABS (where equipped)

Supported systems & software

I use **Bosch eBike Diagnostic Software (v8.1.6.0.0)** for classic Bosch eBike Systems. **Note:** Newer *Smart System* bikes require DiagnosticTool 3.x; I offer read‑only health checks on those when possible.

Fully supported (classic system)

  • Motors: Active Line (+), Performance Line, Performance Line CX, Cargo Line
  • Displays: Purion, Intuvia, Kiox, Nyon
  • Batteries: PowerPack/PowerTube up to 625 Wh

Smart System notes

  • Read‑only diagnostics where possible
  • Firmware update/feature changes not offered
  • Error code help & reports provided

I’ll tell you exactly what’s possible for your bike before any work.

Speed tampering error?

I can help fix the root cause (usually magnet/sensor alignment or removed tuning kits) and then clear the error. If your system is in limited‑assist “limp mode”, I’ll guide you through recovery and perform any dealer‑level resets that are permitted.

Send me your bike model, motor type, and display. I’ll confirm what I can do, what it costs, and how long it takes.
