MBIQ-S Tuning Sensor for Shimano Steps E5xxx - E8xxx E-Bikes with SM DUE11

MBIQ-S Tuning Sensor for Shimano Steps E5xxx - E8xxx E-Bikes with SM DUE11

This is a microcontroller-based sensor solution for e-bikes with Shimano Steps mid-mounted motors. This tuning tool completely removes the 25 km/h speed limit so that you can finally enjoy the full potential of your Shimano motor. The MBIQ-S is thus reduced to the absolute essentials, namely the removal of the speed limit - there are no further functions. Installing the tool is easy, as you basically only need to replace the speed sensor of the e-bike with the MBIQ-S.

The MBIQ-S does not need its own battery.

How it works

After connecting the tuning tool, the MBIQ-S analyses the current speed profile and forwards manipulated sensor values. In doing so, speeds above 25 km/h are blocked for the engine firmware, so that the speed limitation of the engine is cancelled.

Important note: Due to this special mode of operation, the speedometer of the e-bike will no longer display the correct speed from a speed of approx. 22 km/h onwards. To be precise, the displayed speed will then always be ≤ 25 km/h, even if you are actually riding faster.

By the way, the evaluation of the motor software is not affected in any way by the manipulated values / no detection.

Three operating modes

Unlike previous models, the MBIQ-S can be programmed by the customer. The individual operating modes can be switched on by certain wheel movements when the e-bike is switched on. There is a choice of three different operating modes:

-Tuning is always active (the speed limit is permanently lifted, from approx. 25 km/h the displayed speed no longer corresponds to the real speed).

-Tuning is permanently switched off (the speed limit is not lifted, engine support up to 25 km/h with real speed display).

-Tuning after switch-on condition: To switch on tuning, the magnet must be in front of the sensor for approx. 3-4 seconds during start-up, otherwise tuning is deactivated. This can be useful, for example, if you want to switch off the tuning before a workshop visit (the sensor solution is quasi invisible in this case).

Here you can find operating instructions (in German).

Easy installation

The installation of this tuning tool is easy, as you basically only need to replace the original speed sensor with the MBIQ-S.

You will find the sensor on the rear frame, often next to the quick release axle. Depending on the manufacturer, the sensor cable is often routed through the frame. The connector end is plugged into the engine compartment, which is usually protected by a plastic cover.

Depending on the manufacturer and type, it may be necessary to loosen the motor to be able to pull out the sensor cable and to insert the MBIQ-S. On some e-bike models, the sensor cable runs through the frame and must be pulled out carefully. The cable of the MBIQ-S must then be passed through the frame in the same way using a pull wire.

Since the appearance of the MBIQ-S is kept absolutely neutral, your e-bike will not be changed visually in any way by the tuning tool.

Tip: We recommend keeping the original sensor of the e-bike so that the original condition of the bike can be restored if necessary.

Robust & insensitive to moisture

Compared to previous models, the quality of the housing parts of the MBIQ-S has been significantly improved. Thanks to the electronics encapsulated in the sensor, the MBIQ-S is extremely insensitive to dirt and moisture.
