WELCOME TO THE E-BIKE SERVICE
MANUAL MY20.
This Service Manual contains specific information about the e-bike system
components of recent Giant, Liv & Momentum e-bikes. It is designed to be
used by a workshop mechanic, as a technical guide and reference work for
servicing our E-Bikes.
For information about the basic operation and functionality of e-bikes, please
refer to the regular user manual.
Updated or additional information might become available after the initial
release of this manual. If the provided information is insufficient or missing,
please contact the local Giant Service Team for further assistance.

2.1 G-SYSTEM
G-System is the group name for the different components and technologies
that make a Giant/Liv/Momentum bike an e-bike. It utilizes the CANBUS pro-
tocol for digital communication between these components.
Below a quick overview of the main G-System components:
SYNCDRIVE:
SYNCDRIVE is the motor that provides the power assistance to the rider.
The SyncDrive motors contain the main processing unit and all but one of the
sensors.
There are 3 different types of SyncDrive motors in MY20: Life, Sport & Pro. All
three are updated with the latest 6-sensor technology. For MY20 the output
for lights has also been increased to 9 Watt max. (6V/1.5A).
PEDALPLUS:
PEDALPLUS 6-sensor technology are all the sensors that register various
inputs, like speed, cadence, input torque, motor rotation speed, slope and
acceleration. This gives all SyncDrive motors Smart Assist features, to auto-
matically select an assist level based on all sensor data.
RIDECONTROL:
RIDECONTROL is the control unit on the handlebars. It’s the interface that
gives the user control over the e -bike functions.
• The CHARGE and EVO displays are basically unchanged compared
to previous model years, but did receive some small updates in the
firmware.
The RideControl ONE combines core functionality and visual feedback in a
compact and ergonomic unit with minimalistic aesthetics. For MY20, an ANT+
capability has been added to wirelessly connect to various (3rd party) de-
vices.
ENERGYPAK
The ENERGYPAK is the power source of the system. The Integrated batteries
as introduced last year are completely integrated into the frame, and together
with the 6A Smart Charger they can be charged faster and more efficiently.
For MY20, a more compact, 375Wh battery has been added to the line-up,
and an optional 250Wh range extender is added as an opional accessory to
increase the range even more. Integrated batteries compatible with the range
extender are dubbed EnergyPak Smart (500, 400, 375)
Other batteries used for MY19 are semi-integrated side release type, and
carrier types, with can be charged with the standard 4A Fast Charger.

2.2 SYNCDRIVE
SYNCDRIVE PRO MY20
FEATURES:
The SyncDrive Pro motor is designed for performance use. Compared to Syn-
cDrive Sport some specific features are enhanced for performance:
• Light and compact
• Most powerful (360% power ratio)
• Faster engagement and response (more teeth and pawls in clutch
ratchet mechanism)
• Increased max cadence
• 128mm wide Hollow BB axle with ISIS interface
SMART ASSIST:
Each MY20 SyncDrive Motor is equipped with PedalPlus 6-sensor tech-
nology. Switching the assist level down to off, and then one level further, acti-
vates the Smart Assist function (AUTO mode). The Smart Assist will automat-
ically select the optimal power ratio depending on the input of all six sensors.
While this allows the rider to focus on the ride, it also provides an efficient
power consumption
MAXIMUM
CADENCE MY 19 MY20
Power 120 rpm 170 rpm
Sport 120 rpm 170 rpm
Active 120 rpm 155 rpm
Basic 110 rpm 155 rpm
Eco 110 r p m 155 rpm

.TUNING:
The SyncDrive Pro motor provides a power ratio of in a range of 0- 360%. The
RideControl displays have 5 default modes to choose from, that correspond
to 5 power ratio presets in the motor. These modes can be custom tuned, by
using the RideControl mobile app, which allows the user to select a different
power ratio for each mode. More information about the RideControl app can
be found in the app manual.
MOTOR FIRMWARE:
The motor firmware has several layers of programming, that could be de-
scribed as a core layer, a properties layer and a top layer.
The motor’s core firmware and properties are written during the manufac-
turing stage, and are not accessible to any others beyond this stage. Only the
top layer of the firmware is partly accessible to dealers and users, through
the app, to allow the tuning of the power ratios. Dealers have read access to
certain information stored in the motor, like error codes and motor ODO, by
using the Giant Service Tool software and dongle.
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.
CONNECTIONS:
The SyncDrive motor is a central part of the G-system and is connected to all
the other G-System parts, like the RideControl display and EnergyPak. There
are 3 connectors coming directly from the motor:
1. Main Power wire:
2 pin large connector
Red and Black wires (+ and -)
2. Speed Sensor wire:
3 Pin connector
Green, Dark blue, red wire
3. Main communication signals and 5-6V output wires
8 pin connector
Black, Red, White, Dark Blue, Orange, Green, Brown, Pink wire
Please notice: Most signal or power wires are split and routed to other
components via other wires. For example, the 8 pin connector will split into
several connections including the RideControl connector and front and/or rear
light power supply. See the pages on wiring for more details.
ASSEMBLY OF THE SYNCDRIVE PRO MOTOR:
See the SyncDrive Pro motor assembly guide for more details.
