Shimano STEPS error W207: Travel data update failed warning
The drive unit tried to write ride data such as trip distance, average speed and total kilometres to memory and the update failed. Motor assist continues to work normally, but the trip meter, odometer and average speed reading may freeze, jump or reset until the code clears. W207 shows on the display with the standard Shimano warning icon, not the red stop sign.

- Loose or corroded speed sensor connector at the drive unit
- Firmware bug after a recent E-TUBE update or interrupted update

- Moisture or contamination in the display or junction box connector
- Controller failed to commit trip data after an abrupt power cut
- Weak or aged coin cell back-up in the cycle computer losing trip history
How to fix Shimano STEPS error W207
- Switch the system off using the battery power button, not the display power button, and wait at least 10 seconds.
- Power the system back on and check whether W207 has cleared on the display.
- Ride 200-500 metres and confirm the trip metre and odometer are incrementing again.
- Inspect the rear stay spoke magnet, clean it and confirm the speed sensor gap is 1-3 mm.
- Unplug, inspect and reseat the speed sensor connector at the drive unit.
- Run E-TUBE Project and apply any pending firmware updates for the battery, display and drive unit.
- If W207 returns on the next ride, take the bike to the place of purchase for dealer-level diagnostics.

Frequently asked
Can I reset shimano error W207?
Yes. Press and hold the battery power button to switch the system fully off, wait about ten seconds, then power it back on. If W207 reappears on the next ride the reset did not stick and a dealer check is needed.
Is it safe to keep riding with W207?
Yes, W207 is a warning and motor assist keeps working, so you can ride home or to the workshop. Treat the trip metre and odometer as unreliable until the code clears, and book a check if it returns.
Will Shimano cover W207 under warranty and what will it cost?
If a genuine component fault is confirmed within the two-year warranty period Shimano normally covers the part, leaving the dealer diagnostic fee of €40-€80 as the main out-of-pocket cost. Out of warranty, expect €60-€150 for a sensor fix or up to €400+ for a drive unit replacement.
