Fitting

Fitting and removing the on-board computer (see figure A)
Fit the lower part of the Kiox into the holder (5) first and tilt it forward gently until you can feel that the on-board computer is firmly fixed in the magnetic holder.
To remove the on-board computer, hold it by the top end and pull it towards you until it disengages from the magnetic holder.

• Remove the on-board computer when you park the eBike.
  The on-board computer can be secured in place to prevent it from being removed from the holder. To do this, loosen the headset screw (16) until the Kiox holder can be swivelled sideways. Put the on-board computer in the holder. Screw the locking screw (M3 thread, 6 mm long) from below into the thread provided in the on-board computer (using a longer screw may damage the on-board computer). Swivel the holder back into place and tighten the headset screw in accordance with the manufacturer's specifications.

Operation

Before initial commissioning
The Kiox is supplied with a partially charged battery. Before using it for the first time, this battery must be charged for at least one hour via the USB port (see "Power supply of the onboard computer") or via the eBike system.
The control unit should be attached such that the buttons are almost perpendicular to the handlebars.
When using the on-board computer for the first time, the language selection page is displayed initially. You can then choose to have essential functions and indications explained via the <Intro to Kiox> menu item. The menu item can also be called up at a later time via <Settings> → <Information>.

Selecting system settings
Fit the on-board computer in the holder and proceed as follows with the bicycle stationary:
Go to the status page (use the < button (10) on the control unit to get to the first display) and call up the <Settings> with the select button.
You can use the – (11) and + (12) buttons to select the setting you want. You can open the settings, as well as any additional submenus, using the select button (9). You can use the < button (10) to go back to the previous menu from any settings menu.
The following settings can be changed in the <Sys settings>:

• <Brightness>
• <Time>
• <Date [DD.Mon. YYYY]>
• <Time zone>
• <24h form (24h time format)>
• <Brgh backg. (Bright background)>
• <Imp. units (Imperial units)>
• <Language>
• <Factory reset>

Starting up the eBike system
Requirements
The eBike system can only be activated when the following requirements are met:

• A sufficiently charged eBike battery is inserted (see operating instructions for the battery).
• The on-board computer is properly fitted to the holder.

Switching the eBike system on/off
The following options are available for switching on the eBike system:

• Once the on-board computer and the eBike battery are fitted, briefly press the on/off button(4) on the on-board computer.
• With the on-board computer inserted, push the on/off button on the eBike battery (bicycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the battery operating instructions).

The drive is activated as soon as you start pedalling (except if you are using the push-assistance function or if the assistance level is set to OFF). The motor output depends on the settings of the assistance level on the on-board computer. As soon as you stop pedalling when in normal operation, or as soon as you have reached a speed of 25/45 km/h, the eBike drive switches off the assistance. The drive is automatically reactivated as soon you start pedalling again and the speed is below 25/45 km/h.
The following options are available for switching off the eBike system:

• Briefly press the on/off button(4) of the on-board computer.
• Switch off the eBike battery using its on/off button (bicycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bicycle manufacturer operating instructions).
• Remove the on-board computer from its holder.

If no power is drawn from the eBike drive for about 10 minutes (e.g. because the eBike is not moving) and no button is pressed on the on-board computer or the operating unit of the eBike, the eBike system, and therefore also the battery, will switch off automatically to save energy.

Power supply of the on-board computer
If the on-board computer is in the holder (5), a sufficiently charged eBike battery is inserted into the eBike and the eBike system is switched on, then the on-board computer battery is powered and charged by the eBike battery.
If the on-board computer is removed from the holder (5), the power is supplied by the on-board computer battery. If the on-board computer battery's charge is running low, a warning message appears on the display.
To charge the on-board computer battery, slide the on-board computer back onto the holder (5). Note that if you do not charge the eBike battery straight away, the eBike system will automatically switch off after 10 minutes of inactivity. If this happens, the on-board computer battery will also stop charging.
You can also charge the on-board computer via the USB port (6). To do this, open the protective cap (17). Use a Micro USB cable to connect the USB port on the on-board computer to a commercially available USB charger (not included with the product as standard) or to the USB port of a computer (max. 5 V charging voltage; max. 500 mA charging current).
If the on-board computer is removed from the holder (5), all values for the functions are saved and can still be scrolled through.
If the Kiox battery is not recharged, the date and time will be retained for up to 6 months. When the on-board computer is switched on again, the date and time will be reset if a Bluetooth® connection to the app has been established and
the smartphone has successfully identified the current location via GPS.
Note: The Kiox only charges while it is switched on.
Note: If the Kiox is switched off during charging via a USB cable, the Kiox can only be switched on again once the USB cable has been disconnected.
Note: To maximise the lifespan of the on-board computer's battery, it should be recharged for one hour every three months.

Battery Charge Indicator
The battery charge indicator of the eBike battery d (see "Start page") can be read on the status page and in the status bar. The eBike battery's state of charge is also indicated by the LEDs on the eBike battery itself.

If the eBike battery is being charged on the bike, a corresponding notification will be displayed.
If the on-board computer is removed from the holder (5), the state of charge that was last displayed for the battery is saved.

Storage mode/resetting the Kiox
The on-board computer has an energy-saving storage mode which minimises the rate at which the internal battery discharges. Setting to this mode erases the date and time. This mode can only be activated by pressing and holding the on/off button (4) of the on-board computer for at least 8 seconds.
If the on-board computer does not start when the on/off button (4) is pressed briefly, the on-board computer is in storage mode.
You can deactivate storage mode by pressing the on/off button (4) for at least 2 seconds.
The on-board computer detects whether it is in a fully functional condition. If you press and hold the on/off button (4) for at least 8 seconds while in a fully functional condition, the on-board computer will go into storage mode. If, contrary to expectations, the Kiox is not in a fully functional condition and cannot be operated, pressing and holding the on/ off button (4) (for at least 8 seconds) will reset it. After being reset, the on-board computer will restart automatically
after approx. 5 seconds. If the Kiox does not restart, press the on/off button (4) for 2 seconds.
To reset the Kiox to its factory settings, select <Settings> → <Sys settings> → <Factory reset>. All user data will be lost.

Setting the assistance level
On the operating unit (7), you can set the level of assistance you want the eBike drive to provide you with while pedalling. The assistance level can be changed at any time, even while cycling.
Note: In some models, the assistance level may be preset and cannot be changed. There may also be fewer assistance levels available than stated here.
The following assistance levels are available as a maximum:

• OFF: Motor assistance is switched off. The eBike can just be moved by pedalling, as with a normal bicycle. The push assistance cannot be activated at this assistance level.
• ECO: Effective assistance with maximum efficiency, for maximum range
• TOUR: Steady assistance, long range for touring
• SPORT/eMTB:
  SPORT: Powerful assistance, for mountain biking and cycling in urban traffic
  eMTB: Optimum assistance whatever the terrain, rapid acceleration when starting from a standstill, improved dynamics and top performance (eMTB only available in combination with the drive units BDU250P CX, BDU365, BDU450 CX and BDU480 CX. A software update may be required.)
• TURBO: Maximum assistance even at high pedalling speeds, for sport cycling

To increase the assistance level, press the + (12) button on the operating unit repeatedly until the desired assistance level appears on the display. To decrease the assistance level, press the – (11) button.
The requested motor output appears on the display h (see "Start page"). The maximum motor output depends on the selected assistance level. If the on-board computer is removed from the holder (5), the assistance level that was last displayed is saved.

Switching the push assistance on/off
The push assistance aids you when pushing your eBike. The speed in this function depends on the selected gear and can reach a maximum of 6 km/h. The lower the selected gear, the lower the speed of the push assistance function (at full power).

• The push assistance function must only be used when pushing the eBike. There is a risk of injury if the wheels of the eBike are not in contact with the ground while using the push assistance.

To activate the push assistance, briefly press the WALK button on your on-board computer. After activation, press the + button within 3 s and keep it pressed. The eBike drive is switched on.
Note: The push assistance cannot be activated at assistance level OFF.
The push assistance is switched off as soon as one of the following occurs:

• You release the+ button;
• The wheels of the eBike are locked (e.g. by applying the brakes or hitting an obstacle);
• The speed exceeds6 km/h.

The push assistance function is subject to local regulations; the way it works may therefore differ from the description above, or the function may even be deactivated completely. Switching bicycle lights on/off
On the model on which the lighting is powered by the eBike system, the front and rear lights can be switched on and off at the same time via the on-board computer using the bike light button (3).
Check that your bike lights are working correctly before every use.
With the light switched on, the lighting c indicator (see "Start page") appears in the status bar on the display.
Switching the bike lights on and off has no effect on the backlighting of the display.
