Syncdrive Motor; Miscellaneous - Giant Momentum User Manual

orientation is the same.
Can I mount an extra battery on my bike?
∙ On selected models, it is possible to mount an EnergyPak Plus (range extender) battery to increase
total capacity. This EnergyPak Plus can be purchased separately (Availability can vary by country).
Contact your local Giant dealer for more information.
How come the charge times are not even with the capacity?
∙ Charging an EnergyPak is not done in a straight line. Especially the last part takes a lot of time.
Should I always empty my EnergyPak completely before recharging?
∙ There is no need to do complete discharge every time. Complete discharge every 3 months is
appreciated for refreshing EnergyPak management.
What happens if my EnergyPak gets empty while riding?
∙ Obviously, assistance will stop. At 3%, assistance will be less to improve range. At 1%, assistance
will stop completely. Lights will still function for about 2 or 3 hours. Your bike can be ridden without
assistance.

6.3 SYNCDRIVE MOTOR

If I simply rotate my pedals, I hardly get any assistance. How come?
∙ Giant's SyncDrive motor has a torque sensor. The motor assists accordingly the applied force. More
basic systems can use rotation sensor only.
I can feel sideways play on my cranks. Is this normal?
∙ That is ok. Giant SyncDrive Life and Sport motor by Yamaha has been designed with a sideways
play in the bottom bracket axle with a maximum of 1millimeter. This has been done for better
durability under all conditions.
How come competition motors make a different sound?
∙ Giant uses different internal structure than some competitors. As a consequence, we have a slightly
higher frequency and better torque value.

6.4 MISCELLANEOUS

What is the QR code on my bike for?
∙ The QR code can be used to register your bicycle on an anti-theft website.
What is the best way to clean my bike?
∙ The E-parts are best cleaned with a dry cloth. The rest of the bike should be treated as any other
bike.
Can I mount wired lighting system on my bike?
∙ Yes, wiring and buttons are prepared for this. Be sure to use correct type of lighting (6V for example).
My partner rides the same bike as I do. My range is much bigger. How come?
∙ Range is depending on a lot of influences (tire pressure, engaged own power, gear). One of them
may cause this difference.
