FAQ

If the Bosch system detects tampering, the motor noticeably throttles power (limp home mode). This is usually indicated on the display by the following error codes, depending on the specific system:

• 524001
• 525001
• 525002
• 525003
• 525004

• 504

The procedure depends on how often tuning has already been detected:

• After the 1st and 2nd detection (Temporary limp home mode): You must ride the e-bike for more than 90 minutes without detected manipulation in its original condition. Simply turning it off and on is not enough! The full 90-minute riding time must be completed.
• After the 3rd detection (Permanent limp home mode): The 90-minute ride is unfortunately no longer sufficient. The limp home mode is permanently activated and can only be reset by an authorized Bosch specialist dealer using the Bosch DiagnosticTool 3.

To avoid limp home mode and an expensive visit to the dealer, we recommend a clear limit for the RedPed App: Limit the speed to a maximum of 33.0 km/h!

Although technically much higher speeds are possible, the risk of permanent tuning detection increases massively if values above 33.0 km/h are set. Any setting beyond this is at your own sole responsibility.

The EP6 and EP801 motors have integrated tuning detection. Error code W292 (accompanied by an acoustic signal) is the first warning level during a ride.

However, this error can also occur if no signal is received from the speed sensor and the speed remains at 0 km/h when starting off. In this case, there may be a problem with the magnet or the tuning chip is defective.

If you ignore the initial error W292, error code E295 will follow, appearing up to four times. On the fifth occurrence, error E299 will be displayed.

Once E299 occurs, a visit to a Shimano workshop is unavoidable. The motor must be removed and sent to the Shimano distributor Paul Lange. The cost for unlocking there is €119 plus VAT, plus workshop costs for installation and removal.
