Shimano STEPS error E014: Speed sensor signal abnormal
The drive unit has lost a sensible pulse from the wheel speed sensor, so it cannot confirm how fast the bike is moving. As a result motor assist cuts out, the display shows a speed of 0 km/h even while riding, and walk assist stops working. The error latches on the display until the cause is corrected and the system is restarted.

Likely causes
- Spoke magnet loose, missing, or knocked out of alignment after a wheel removal.
- Sensor bracket bent or sensor displaced from the rear dropout mount.
- Connector at the speed sensor or drive unit loose, dirty, or corroded.
- Cable from the speed sensor to the drive unit pinched, cut, or stretched.
- Magnet installed with the dimple facing away from the sensor, common after a wheel refit.
- Water ingress in the sensor plug after heavy rain or washing.
How to fix Shimano STEPS error E014
- Switch off the system and remove the battery before any inspection.
- Locate the speed sensor on the left rear dropout and the small disc magnet on a rear spoke.
- Confirm the magnet is present, tight, and that the side with the recess faces the sensor as it passes.
- Check the sensor sits squarely in its bracket with a gap of roughly 3 to 5 mm to the magnet; reseat if it has moved.
- Unplug the sensor connector, look for green corrosion or bent pins, and refit it firmly; trace the cable back to the drive unit for obvious damage.
- Refit the battery, power on, and spin the rear wheel while watching for a speed reading to confirm the signal has returned.
- If the code reappears immediately, the sensor itself or its wiring is faulty and a Shimano dealer must diagnose and replace the affected part.
Warranty: A genuine sensor or wiring fault within the standard two-year component warranty is normally covered, while crash damage, water ingress, and magnet loss caused by the rider are treated as wear and excluded.
Typical cost: A replacement speed sensor typically costs around €20 to €45 and a magnet under €10; dealer labour for diagnosis and fitting usually adds €40 to €80, putting a typical repair between €60 and €130.
Frequently asked
Can I reset shimano error E014?
A power cycle clears the display, but E014 will return on the next ride if the magnet, sensor, or wiring fault is still present. The reset only confirms the underlying problem is fixed once the code stays off.
Is it safe to keep riding with E014?
The bike still rolls and brakes work normally, but motor assist and walk assist are unavailable, which makes hill starts and tight manoeuvres harder, and you should avoid heavy loads or steep climbs until the fault is resolved.
How much will a shimano E014 repair cost and is it under warranty?
Most repairs land between €60 and €130 including parts and labour, and if the sensor or wiring fails inside the two-year warranty period with no sign of impact or water damage, Shimano usually covers it.
