3 OVERVIEW E-PARTS
3.1 EXPLANATION
Momentum E-bikes, handcrafted by Giant, are equipped with parts that work together to make a
smooth and powerful assisted E-bike.
Giant’s integrated Lithium-ion battery packs are unique because they have the highest energy density
in the market. If we consider weight and size, Giant EnergyPaks produce the best performance in an
integrated package. Furthermore, this EnergyPak charges twice as fast compared to earlier battery
systems and provides a superb maximum range. The batteries are thoroughly tested in Giant factories
to ensure reliability. Momentum E-bikes are equipped with the EnergyPak Smart 375, the most compact
of Giant’s integrated EnergyPaks.
Powered by YAMAHA
Innovation, manufacturing expertise and a motor system powered by Yamaha all combine to help
extend any rider’s abilities. The SyncDrive motor is widely acclaimed for its performance and reliability.
The small mid-drive motor is capable to deliver up to a massive 80Nm (Newton Meters) of torque,
and delivers smooth pedaling power that’s tuned for optimal performance on each model. The latest
6-sensor technology makes it possible for the bike to automatically choose an optimal power ratio, so
the rider can just enjoy the ride even more.
The handlebar-mounted command center provides easy-to-operate controls with a more ergonomic
button that controls the support levels in a comfortable way. The RideControl provides riders with the
following important information:
• Battery level indicator
• Support level indicator
• Light indicator
The lowest power assist levels can be used for riding urban and suburban roads when minimal
assistance is needed. Eco level requires less battery capacity and helps you cover a greater distances.
The highest levels gives you the highest power boost to climb steep hills. It’s the perfect choice when
you’re riding the most challenging mountains and terrain. The Smart Assist feature will even adjust the
power assist automatically and in real time, in response to the riding conditions.

3.2.3 New EnergyPak
A new EnergyPak is shipped in a protective ‘hibernate’ state. Such an EnergyPak needs to be activated
before it can be used;
• A ‘hibernate’ EnergyPak can be recognized by pushing the energy level check button. The LED’s of
the EnergyPak will not light up.
• Plug an active charger in the EnergyPak.
• Unplug the charger from the EnergyPak.
• The EnergyPak is now out of ‘hibernate’ state. Pushing the energy level check button will result in
lighting up LED’s.
• The EnergyPak is ready for usage.
It is not possible for an EnergyPak to go back to ‘hibernate’ state once it is awoken.
Usually, the dealer will charge the EnergyPak and therefore undo ‘hibernate’ state.

3.2.4 Charging
• Charging the EnergyPak battery should be at room temperature (±20°C/68°F). Charging below 0°C
or above 40°C (32°F~104 °F) can lead to insufficient charging and can be harmful to the battery life
cycle.

3.2.5 Usage
The bike will draw power from the battery when it is
switched on. If only 3% of the EnergyPak power is
left, the EnergyPak will automatically switch assistance to ECO mode in order to save energy.
If only 1% of the EnergyPak power is left, assistance
will automatically stop. Power assist level indication
bar will blink 3 times. Lights can still be used for
over 2 hours.
Power in the EnergyPak can be checked by pushing the Energy Level check button.
The EnergyPak should be used at temperatures
between 0°C and 40°C (32°F and 104°F). Using
the EnergyPak at higher or lower temperatures can
negatively influence the range or could result in unexpected errors. Prolonged use during very high or
low temperatures can be harmful to the battery life cycle.
After 15 normal charges, or at least every 3 months, discharge the EnergyPak completely by
riding the bicycle before charging the EnergyPak again. This will increase the lifespan of the
EnergyPak.
When an EnergyPak is connected to the bike, some small amount of power will get lost in the system
when the bike is not in use. To prevent this, the EnergyPak can be disconnected from the bike when not
in use for more than a few days.
3.2.6 Storage
If the bike is not used for a longer period (one month or more) the EnergyPak is best stored:
• At 60% of its capacity. For ‘smart charger’, that is a functionality.
• Separate from the bike.
• At temperatures between 0°C and 40°C (32°F and 104°F).
• Checked every month to see if at least one LED is still blinking. Charge when needed.
Charging the EnergyPak should be done at a minimum of every 3 months. Negligence to this could void
the warranty of the EnergyPak.
The SyncDrive motor is responsible for the
pedalling assistance of your E-bike.
Information from internal sensors and the speed
sensor are being processed to give a smooth and
natural ride. Sideways play of the bottom bracket
axle of one millimeter maximum is designed in the
SyncDrive motor for maximum durability.
