Safety Information
Warning!
· Install and adjust this bicycle ONLY in accordance with these instructions.
Read them completely prior to installation and use. Contact customer service
if any point is unclear.
· ALWAYS obey all applicable local and national laws and regulations while
riding. Do not ride this bicycle in any area prohibited to electric bicycles.
Always wear your helmet and other required protective gear. Always maintain
your reflectors and other required safety equipment.
· Check whether the brakes function well using the brake levers before riding.
Even after power is cut to the motorized wheel, the inertia of the bike will
often require active braking power.
· ALWAYS ensure all fasteners and components are intact and securely tightened
before and after every use.
· DO NOT ride this bicycle if any part is damaged or malfunctions. Repair or
replace worn and broken parts before further use.
· Pay attention to the remaining power before setting out and during use.
Recharge your battery as needed to ensure it never runs out of power at a
moment where you are taken by surprise.
· DO NOT allow children or persons unfamiliar with these instructions to
operate this bicycle without strict supervision.
· DO NOT wear loose footwear or clothing that may become caught in the wheels
or any other moving parts.
· It is recommended that you not ride your bike fast when getting started.
This can be ensured by setting the bike’s maximum speed limit low until you
are fully familiar with your new electric bike and its controls.
· ALWAYS be alert for people, animals, or any obstacles that may appear in
front of you while riding your bicycle. Be aware that pedestrians and drivers
may not expect the speed or responsiveness of your bike. Adjust your behavior
accordingly. It is advisable to install warning devices to draw their
attention, but always be ready to turn safely out of their way if needed. Do
not focus on the LCD display for extended periods of time while riding.
· NEVER ride at a speed where your stopping distance exceeds your visibility.
We do not recommend that you ride your bicycle at night or in an environment
with poor visibility. If you have an emergency that makes it necessary to do
so, keep your light on and limit your speed appropriately.
· DO NOT get the battery, its charger, or its power cord wet or operate them
with wet hands.
· NEVER use the pedal assist system (PAS) or timed shutoff in any situation,
road condition, or terrain where doing so might impair your control of your
bicycle.
· NEVER adjust 03, 06, or 07 on the LCD display panel. Adjustment of these
parameters should only be made when using the display with other compatible
motorized wheels of differing voltage, diameter, or magnet arrangements. In
any other case, any adjustment of these parameters should be undone
immediately and the original settings restored before any further use of this
bicycle.
· Disconnect the battery from this bicycle before any cleaning, servicing, and
storage.
