E-BIKE SYSTEMS
The e-Bike Systems are designed to give you the optimal amount of
power assist.
It assists you within a standard range based on factors such as your pedaling strength, bicycle
speed, and current gear.
The e-Bike Systems do not operate in the following situations:
• When the display unit’s power is off.
• When you are moving 45 km/h or faster.
• When you are not pedaling.
• When there is no residual battery capacity.
• When the automatic power off function* is operating.
* Power turns off automatically when you do not use the e-Bike Systems for 5 minutes.
• When the assist mode is set to Off mode.
• When the running assist switch is released.
• When the display unit is removed.
Four types of “assist mode” + Off mode are available.
Choose from High-Performance mode, Standard mode, Eco mode, +Eco mode and Off mode to
suit your riding conditions. See “Displaying and switching the assist mode” for information on
switching between assist modes.
High-Performance mode Use when you want to ride more comfortably, such as when
climbing a steep hill.
Standard mode Use when riding on flat roads or climbing gentle hills.
Eco mode
+Eco mode Use when you want to ride as far as possible.
Off mode Use when you want to ride without power assist. You can still use
the other display unit functions.

SAFETY INFORMATION
Never use this battery charger to charge other electrical appliances.
Do not use any other charger or charging method to recharge the special batter-
ies. Using any other charger could result in fire, explosion, or damage the batter-
ies.
This battery charger can be used by children aged from 8 years and above and
persons with reduced physical, sensory or mental capabilities or lack of experi-
ence and knowledge if they have been given supervision or instruction concern-
ing use of the battery charger in a safe way and understand the hazards in-
volved. Children shall not play with the battery charger. Cleaning and user
maintenance shall not be made by children without supervision.
Although the battery charger is waterproof, never allow it to become immersed
in water or other fluids. In addition, never use the battery charger if the terminals
are wet.
Never handle the power plug, charge plug or touch the charger contacts with wet
hands. This could result in electric shock.
Do not touch charger contacts with metallic objects. Do not allow foreign materi-
al to cause short circuit of the contacts. This could result in electric shock, fire,
or damage the battery charger.
Periodically remove dust from the power plug. Dampness or other issues could
reduce the effectiveness of the insulation, resulting in fire.
Never disassemble or modify the battery charger. This could result in fire or elec-
tric shock.
Do not use with a power strip or extension cord. Using a power strip or similar
methods may exceed rated current and can result in fire.
Do not use with the cable tied or rolled up, and do not store with the cable
wrapped around the charger main body. Cable damage can result in fire or elec-
tric shock.
Firmly insert the power plug and the charging plug into the socket. Failure to in-
sert the power plug and the charging plug completely can result in fire caused
by electric shock or overheating.
Do not use the battery charger near flammable material or gas. This could result
in fire or explosion.
Never cover the battery charger or place other objects on top of it while charg-
ing. This could result in internal overheating leading to fire.
Do not touch the battery pack or battery charger while it is charging. As the bat-
tery pack or battery charger reaches 40–70 °C during charging, touching it could
result in low-temperature burns.

SAFETY INFORMATION
Do not short the contacts of the battery pack. Doing so could cause the battery
pack to become hot or catch fire, resulting in serious injury or property damage.
Do not disassemble or modify the battery pack. Doing so could cause the battery
pack to become hot or catch fire, resulting in serious injury or property damage.
If the power cable is damaged, stop using the battery charger and have it in-
spected at an authorized dealer.
Do not turn the pedals or move the bicycle while the battery charger is connect-
ed. Doing so could cause the power cable to become tangled in the pedals, re-
sulting in damage to the battery charger, power cable, and/or plug.
Handle the power cable with care. Connecting the battery charger from indoors
while the bicycle is outdoors could result in the power cable becoming pinched
and damaged in a doorway or window.
Do not run over the power cable or plug with the wheels of the bicycle. Doing so
could result in damage to the power cable or plug.
Do not drop the battery pack or subject it to impact. Doing so could cause the
battery pack to become hot or catch fire, resulting in serious injury or property
damage.
Do not dispose of the battery pack in a fire or expose it to a heat source. Doing
so could cause fire, or explosion, resulting in serious injury or property damage.
Do not modify or disassemble the e-Bike Systems. Do not install anything other
than genuine parts and accessories. Doing so could result in product damage,
malfunction, or increase your risk of injury.
When stopped, be sure to apply the front and rear brakes and keep both feet on
the ground. Placing one’s foot on the pedals when stopped may unintentionally
engage the power assist function, which could result in loss of control and seri-
ous injury.
Do not ride the bicycle if there is any irregularity with the battery pack or e-Bike
Systems. Doing so could lead to loss of control and serious injury.
Be sure to check the residual battery capacity before riding at night. The head-
light powered by the battery pack will turn off soon after the residual battery ca-
pacity has decreased to where power assisted riding is no longer possible. Rid-
ing without an operating headlight can increase your risk of injury.
Do not start off by running with one foot on a pedal and one foot on the ground
and then mounting the bicycle after it has reached a certain speed. Doing so
could result in loss of control or serious injury. Be sure to start riding only after
you are seated properly on the bicycle seat.
Do not press the running assist switch if the rear tire is off the ground. Other-
wise, the tire will turn at high speed in the air and you could be injured.
Do not remove the display while riding the bicycle. Doing so will turn off the
power assist, and could result in the bicycle falling over.
