RedPed 2s for Shimano EP8

RedPed 2s for Shimano EP8 (also with Di2 gears)

Use the RedPed 2s tuning module to get the best out of e-bikes with Shimano EP8 motors.

The RedPed 2s module is one of the most comprehensive tuning tools available for e-bikes with Shimano EP8 drives. In addition, the module is compatible with the RedPed 2 app, offering a wide range of optimisation options.

The core function of the RedPed 2s is the cancellation of the 25 km/h speed limit, whereby numerous other settings can be made via the app, e.g. the maximum speed can be set individually or an individual activation code can be set. The app can also be used to display many useful riding parameters while cycling, including the actual speed and the distance travelled.

Compared to its predecessor, the RedPed 2 Plus, the RedPed 2s offers a whole range of interesting improvements, e.g. the real speed can now be read off the e-bike display for the first time (via the second digit and the decimal place of the display).

Note: After installation, the RedPed can be activated/deactivated both via the app and via the control buttons on the e-bike. It is therefore not necessary to take your smartphone with you on every ride.

Here are the new features of the RedPed 2s (compared to the previous RedPed 2 Plus):

-Real speed can be read as a decimal number in the e-bike display (previously only half of the actual speed was displayed): From a speed of 22 km/h, the actual speed is displayed via the second digit and the decimal place of the display (a displayed speed of 23.5 km/h would therefore correspond to a real speed of 35 km/h, etc.).

-Very precise setting of the wheel circumference via the AUTO function. Please note that a correct setting is important for a correct speed display.

-“Mountain mode" for Di2 shifting: As the divided speed generated by the RedPed module always lags one wheel revolution, e-mountainbikes with Di2 gears can cause error W011 at low speeds. The new function synchronises the speed of the e-bike and the RedPed while riding (this can result in small jumps in the speed display on the e-bike display).

-The tracking is now calculated automatically, even without having to enter the mileage.

-Easier reset of the module: Switch on the e-bike and then plug the enclosed reset cable into the reset plug. The RedPed module is reset after 20 seconds. Then simply remove the cable again.

RedPed 2s for Shimano EP8 - Functions

-Removal of the 25 km/h speed limit, which enables much faster riding with full motor support.

-Set maximum speed: The app can be used to set the maximum assisted speed to an individual value, from 15 km/h to 45 km/h ( 45 km/h is the theoretical maximum speed, the real achievable speed depends on various factors, e.g. chainring and motor).

-Display of detailed riding parameters via the app (see below).

-Tuning can be switched on and off via the app or using the light button. When activating using the light button, you can specify how often the light must be switched on and off to activate the tuning (press 0-20 times). The counter function shows how often the light has already been switched on and off.

-Use the app to set whether the tuning should only be active for one journey or always.

-Tuning timer: With this function, the tuning is deactivated after a self-set time as soon as you have brought the bike to a standstill (between 10 and 180 seconds).

-Visibility: Set how long the module should be visible in the app after the e-bike has been switched on. This can prevent unauthorised access by third parties.

-Combination for visibility": Here you can set how often the light must be switched on and off to make the module visible.

-"Divide speed at": Sets how the speed should be divided (10-24 km/h). The higher the value is set, the better. However, if it is set too high, the assistance will stop before the maximum speed is reached. In this case, the set value must be reduced again.

-Enter the wheel diameter: Entering the exact wheel diameter ensures an exact speed display as a decimal number in the e-bike display (AUTO function).

-Show real speed in the display as a decimal number (yes / no).

-Switch mountain mode on and off (see above).

-Tracking: This value shows how many KM the motor is missing due to speed dividing.

-Optional correct kilometre reading after the module has been removed again.

Data display via app

The RedPed app not only allows you to define the settings of the tuning module, it can also display numerous useful riding parameters while cycling. You can customise the display according to your personal preferences - e.g. you can hide values or change the colours of columns & lines, etc. You can also change the font size in the settings (Android) or zoom into the speedometer (iPhone).

Here are the displayed riding parameters, they are always real values:

- Tuning status (on/off)

- Current speed

- Maximum speed

- Riding time

- Average speed

- Distance travelled

- Mileage

Firmware update

If required, a firmware update for the RedPed 2s module can be carried out, but only via the RedPed 2 app for Android. To do this, open the menu in the app and click on "Firmware Update". The "RedPed Version" shows the current firmware. The "Image Version", on the other hand, is the latest version. If this is higher than the "RedPed Version", the "Start Update" button is displayed. As soon as you press the button, the update is started. After the update, the module restarts, whereby all settings are retained. Do not switch off the e-bike during the update.

Installation & functionality

The RedPed 2s module must be connected between the speed sensor and the motor (to gain access to the required plug connections, the protective cover of the motor must be removed briefly). In most cases, the module can be placed in the connection area of the motor (sometimes also in the frame tube). More detailed information can be found in the operating instructions. The RedPed module does not require its own battery; power is supplied via a free display socket.

The electronics of the module have been coated with a layer of varnish and are also protected by a shrink sleeve with internal adhesive.

After installation, the module measures the actual speed and generates its own speed signal for the engine control unit. This generates a lower speed, so that the 25 km/h speed limit is effectively outwitted. This enables much faster riding with full engine support.

You can find detailed installation and operating instructions here.

Compatibility

This RedPed 2s module is compatible with:

-E-bikes with Shimano Steps EP8 / DU-EP800 motors (motor firmware v4.1.11)

-Compatibility with EP801 & EP6 has not been tested and can therefore not be guaranteed!

-Compatible with all displays

-Compatible with Di2 shifting

Important: The tuning function of the RedPed 2s module can only be guaranteed up to the motor firmware version specified above. If the Shimano motor is updated to a higher firmware version after purchasing the module, the tuning function can no longer be guaranteed. So please do not carry out any updates on the Shimano e-bike!
