RedPed for Bosch Smart System BES3 Gen4 Tuning E-Bike (NOT for Valve Magnet)

Compatibility

Only for Bosch Smart System Gen4 with spoke magnet or magnet on the brake disc.

Motor Firmware: The module is compatible with all firmware versions of the motor.

E-Bike Display: The module is compatible with all displays. Also compatible if the e-bike has no display.

Important note on tuning detection: The Bosch Smart System has tuning detection on all firmware versions. Therefore, we recommend setting the maximum speed only up to 33 km/h. However, tuning can be unlocked up to 45 km/h at your own risk.

Functions and Settings

• Max Speed: Adjustable from 15 to 45 km/h in the RedPed app
• Firmware Updates: Conveniently possible via the app
• True Speed: Displayed as a decimal number on the e-bike display (e.g., 33 km/h shows as 23.3 km/h on the e-bike display)
• Tuning Activation: Selectable via the app, with the speed sensor magnet, or by speed
• Tuning Timer: Tuning automatically deactivates after a set time while stationary
• Max Speed Limitation: Standard set to 33 km/h due to Bosch anti-tuning. Can be unlocked to 45 km/h upon request
• Boost function: Every 10 minutes of riding, the max speed is set to 45 km/h for 1 minute (simulating a steep uphill). This allows 45 km/h even without permanent activation of the module
• Statistics: Detailed information about the tuning available directly in the app
• Tracking: The distance traveled can be tracked in the app
