INSTRUCTION MANUAL FLOW
FIT MASTER NODE BASIC + FIT REMOTE PURE LEFT PINION
Motor assistance for energy-saving cross-country trips or moderate off-road terrain
ECO Minimal motor assistance with optimum efficiency for maximum range.
OFF
No motor assistance. The e-bike rides like a normal bicycle. All on-board computer functions are available.
5.2.1 TRAILING
Trailing ensures that the motor assistance remains active for a short time when you stop pedaling. The pre-set trailing makes the power delivery of the Pinion MGU even more harmonious and natural for city and trekking e-bikes, as the lack of force with the vertical pedal position at low cadence is easily overcome. In technically demanding situations and in the event of obstacles on the terrain, the riding pace is noticeably improved with trailing, should you decide to stop pedaling. If you deactivate this feature, the MGU immediately stops the motor assistance once you stop pedaling.
INFO-CIR
NOTICE Trailing is activated by default, and can be deactivated only via the FIT E-Bike Control App. To use the FIT E-Bike Control App, your smartphone must be connected to the e-bike using a FIT Key Card (see Section l 5.1.2).

5.2.2 PUSHING AID (Only available in conjunction with FIT Remote Pure left.)
Pushing aid mode enabled: all LEDs light up white. Pushing aid started: the white island moves up slowly.
The pushing aid makes it easier to push the e-bike. The e-bike can be moved out of underground parking or along steep paths comfortably by activating the pushing aid. To activate the pushing aid mode, press the ring on the FIT Remote Pure left until the white LED display appears at the top. The pushing aid is started by pressing up again and holding the ring on the FIT Remote Pure left. If you release the ring on the FIT Remote Pure left for longer than five seconds, you will quit the pushing aid mode. The choice of gear affects the force that is applied and speed of the pushing aid. Always use first speed for the pushing aid to protect the drive.
Exclamat
CAUTION When using the pushing aid, the wheels must be in contact with the ground to avoid the risk of injury.
5.2.3 BOOST FUNCTION (Only available in conjunction with FIT Remote Pure Left.)
All LEDs are magenta and 1 slightly darker LED moves up quickly.
You can temporarily increase the motor assistance to FLY with the boost function, no matter what assistance level is set (ECO, FLOW, FLEX) . This function can be activated at speeds of 7 km/h and over and if at least one quarter pedal revolution has been detected. The Boost function cannot be used if the pushing aid mode is active. . In order to activate the Boost function (only possible while riding), press and hold down either the function button or the ring up on the FIT Remote Pure Left. The Boost function is activated as long as the ring or button is held down.

5.3 LIGHTS
FIT MASTER NODE BASIC + FIT REMOTE PURE LEFT PINION
On: LEDs come on in white from the bottom to the top and then disappear again. Off: LEDs come on in white from top to bottom and then disappear again.
The lights are switched on or off by briefly pressing the on/off/light button of the FIT Master Node Basic. Various lighting systems are installed depending on the area of use and bicycle type. If this has a daytime running light function, the system will always switch automatically between low beam and daytime running light.
5.4 E-SHIFT
Use the up/down buttons on the gear shift to select the gear manually. You can switch to or exit the automatic mode selected in the settings menu (Auto.Shift or Auto.Shift.Pro) by pressing and holding the button (3 seconds) on the front lever of the Pinion TE1 e-trigger.
The gearbox provides assistance with 9-speed and 12-speed. You can shift through multiple gears at once (e.g. from 06 to 02). Changing gears while stationary or when the crank is at rest or rotating backward is possible, and protects the gearbox.
Shifting down (12-11-10 … -01): Possible to a limited extent under load-bearing. Shifting will not be available if there is too much pressure on the pedal.
Shifting up (01-02-03 … -12): A mechanism in the gearbox allows you to shift up under load; the pressure needs to be briefly released from the pedal only when changing between the respective sub-gearboxes.
For P1.9 motor only: When shifting up from 03 to 04 and from 06 to 07, always make sure to release any pressure from the pedal.
For P1.12 motor only: When shifting up from 04 to 05 and from 08 to 09, always release pressure from the pedal.
INFO-CIR
NOTICE Occasionally, the crank may «drop» after a gear shift by about 10°, causing a brief jerk until the shifter pawl engages in the next tooth. This is normal and does not damage the gearbox.

INSTRUCTION MANUAL
FIT MASTER NODE BASIC + FIT REMOTE PURE LEFT PINION
AUTO.SHIFT
In Auto.Shift mode, the up/down button (e.g. Pinion TE1 E-Trigger) is used to reduce/increase the cadence (pedal frequency).
AUTO.SHIFT.PRO
Auto.Shift.Pro is designed for sporty, dynamic riding and automatically changes to the gear that matches your cadence (pedaling frequency) defined in the settings menu. In contrast to Auto.Shift mode, with Auto.Shift.Pro you use the control unit (e.g. Pinion TE1 E-Trigger) not only to adjust the cadence, but also to override automatic mode and manually set the desired speed in every situation.
If you change gear manually in Auto.Shift.Pro mode, the system registers your current cadence and adjusts the automatic gear shifting according to your preference. If you want to return to the original cadence (the number in the settings menu) while riding, you can do this by pressing and holding the button (3 seconds) on the rear lever of the Pinion TE1 E-Trigger.
INFO-CIR
NOTICE With the FIT E-Bike Control App, you have full control over your E-Shift functions. Either the current gear or the status of Auto.Shift or Auto.Shift.Pro is displayed on the FIT Drive Screen. You can adjust all electronic shifting settings directly in the app. To use the FIT E-Bike Control App, your smartphone must be connected to the e-bike using a FIT Key Card (see Section l 5.1.2).
