4 BIKE USAGE

4.1 MAINTENANCE

Giant Hybrid E-bikes use plastic shells to cover the electric parts, so it is forbidden to use excessive
water to wash the plastic. Use a soft cloth with a neutral solution to wipe the dirt off the plastic shells.
After that, wipe it dry with a clean soft cloth.
Do not use high-pressure water or air hoses for cleaning. It can force water into electric
CAUTION
components, which may cause malfunctioning.
Do not wash the e-bike components with excessive water. If the internal electrical parts are
CAUTION
infected with water, the insulator may corrode which leads to power-drain or other problems.
Do not use non-neutral soap solutions to wash the plastic components. Non-neutral solutions
may cause colour-change, distortion, scratching etcetera.
Avoid leaving the bike outdoors.
When not riding, keep the bike in a location where it will be protected from snow, rain, sun etc. Snow
and rain can cause the bike to corrode. The ultraviolet light from the sun can fade the paint or crack any
rubber or plastic on the bike.

4.2 KEYS

The bike comes standard with two keys that are used for the battery lock. Some bike come standard
with a ring lock as well. For those bikes the keys fit both locks. A qualified locksmith can duplicate the
keys. For bikes without bike lock, on-board charging can lead to the battery lock key being unused for a
long period. This key is needed for maintenance and repair however. Be aware of this when storing the
key.
∙ Keep key-number and non-used key(s) in a safe place for repairs and emergencies.
∙ Make sure to have always at least one spare key.
∙ Always bring the key when going to the dealer for maintenance or repairs.

4.3 RANGE

The range on one charge strongly depends on several circumstances, such as (but not only):
∙ Weather conditions such as ambient temperature and wind;
∙ Road conditions such as elevation and road surface;
∙ Bike conditions such as tire pressure and maintenance level;
∙ Bike usage such as acceleration and shifting;
∙ Rider and luggage weight;
∙ Charge and discharge cycles.

4.4 SHIFTING RECOMMENDATIONS

For better range, Giant advises to shift according to the speed. For low speeds and setting off, low
gearing is best. The higher the speed, the higher the gear can be chosen. For smooth support and
optimum range, it is best to release pedal pressure while shifting gears.
∙ High speed, high gear.
∙ Low speed, low gear.
∙ Release power during shifting.
