What's Included

What's included in motor diagnostics

When an ebike motor acts up, most shops throw parts at it. We don't. We connect to the system, pull codes, and isolate the failing component before we quote any repair.

  • Hub motor bench testing including winding resistance and phase checks
  • Mid-drive motor testing for Bosch, Shimano EP8/STEPS, Bafang, Yamaha, Brose
  • Controller diagnostics and input/output verification
  • Torque sensor and speed sensor calibration
  • Error code retrieval using OEM diagnostic software
  • Wiring harness and connector inspection
  • Written diagnostic report for warranty claims

Error codes tell a story

A flashing battery icon on a Bosch display can mean a dozen different things. We pull the actual fault code, cross-reference it against the manufacturer's database, and tell you whether it's a loose speed sensor magnet or a failing motor controller.

That specificity is the difference between a $40 cable fix and a $900 motor replacement that wasn't needed in the first place. We do the diagnostic work before we quote the repair.

Common Questions

Motor Diagnostics questions, answered.

What brands do you service?

We diagnose and service Bosch, Shimano STEPS and EP8, Bafang (BBS02, BBSHD, M500, M600, Ultra), Yamaha PW, Brose, Heinzmann, and most direct-to-consumer hub motor systems including those on Rad, Aventon, Lectric, Ride1Up, and Juiced.

What does 'error code diagnostics' mean?

Most ebike systems log fault codes when something goes wrong. We connect to the motor or controller with OEM software and read the codes directly, which tells us exactly what the system thinks is failing. Far more reliable than guessing from symptoms.

Can you fix a dead motor?

Sometimes. Hub motors with a blown controller are often repairable. Hub motors with internal winding failure usually need replacement. Mid-drive motors with gear or bearing issues can sometimes be rebuilt depending on brand. We diagnose first and tell you the real options.

Do you handle manufacturer warranty?

Yes, for most supported brands. If your ebike is within warranty, we'll pull the diagnostic data, document the issue, and coordinate with the manufacturer. You get the repair; we handle the paperwork.

My motor cuts out intermittently. What causes that?

Most common causes: a loose or corroded speed sensor, a failing torque sensor, a battery with a weak BMS cell, or a cracked motor wiring harness. All four produce similar symptoms. Diagnostics is the only way to know for sure.
