G-System - Giant MY20 Service Manual

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.
