SENSORS: The MY20 SyncDrive Pro motor uses PedalPlus 6 sensor technology to op- erate: Speed, pedaling torque, pedaling cadence, motor rpm, slope & accel- eration. More information about the sensors can be found in the PedalPlus chapter further on in this manual.

    6. INTEGRATED SPEED SENSOR New in MY20 is the integrated speed sensor. This sensor works the same as the external sensor, but is integrated into the left rear dropout. The magnet is mounted on the disc-brake rotor using 2 of the 6 rotor mounting bolts.
  • Page 16 SMART ASSIST The six separate sensor signals are processed by the G-System software, which optimizes the motor output while riding within any set assist mode. The Smart Assist mode (Auto) goes a step further, by using the sensor data to continuously adjust and balance the power ratio automatically between the available 50-360% (depending on motor type).

    LED lights. ANT+ In MY20, ANT+ connectivity is added to the RideControl One. Bike computers and other devices that support the ANT+ LEV (Light Electric Vehicle) profile can display various E-bike fields, like battery capacity, remaining range and assist level.
  • Page 18 LED INDICATORS: BATTERY CHARGE LEVEL INDICATOR The row of 5 LEDS (B1 - B5) located near the edge of the RideControl One indicate the battery charge level. Each LED represents a block of approx. 20% battery charge. So when all battery LEDS are on, this would mean that the battery is charged to about 80-100%.
  • Page 19 ASSIST LEVEL INDICATOR The row of 5 LEDS (L1 - L5) located next to the Assist UP/DOWN buttons indicate the selected assist level. More lights on means more power assist. When all assist lights are off, the motor assist will be off. SMART ASSIST INDICATOR Press Assist Down button a few times down to Assist OFF, and 1 press more to activate the Smart Assist function.
  • Page 20 ERRORS In the case of an error, the RideControl One will indicate with the LT LED blinking in red that there is an error, and one of the white Assist LEDS (L1, L2, L3 or L5). will blink to show which component the error is related to. Below an overview of the errors the RideControl One can show.
