Bike usage17

4.3Keys
The Pakyak E+ comes standard with two identical keys that fit the battery lock and the
storage box lock. Keep one of the keys with the key number tag stored as a spare. Write
down the key number and keep that stored together with the bike's frame number and
other documents.
NOTICE:
• Always bring the key when visiting the dealer for maintenance or repairs.
• Without the key, a locked battery and/or storage box cannot be opened/
removed without damage.
• Make sure you always have at least one spare key.
• It is recommended to get an extra spare copy of the key.
• A qualified locksmith can make a duplicate of the original keys.
• Store your key number and spare key(s) in a safe yet accessible place.
4.4Riding range
Riding range can be difficult to predict accurately. A higher capacity EnergyPak will
provide a higher range when all other factors are the same. But in practice there are many
factors that influence energy consumption, and they can vary greatly. An understanding of
how particular factors will affect energy consumption, together with experience, will help
to optimize the riding range and start your trip with confidence.
4.4.1Factors that affect range
The range on one charge strongly depends on several circumstances, such as (but not
limited to):
• The total vehicle weight including the rider, passengers and cargo loaded onto the bike.
• 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.
• Amount of charge and discharge cycles.
• Age and condition of the EnergyPak.
• Bike usage, such as acceleration and shifting.
• Assist level(s) used.
• User assist level settings (by smartphone app).
INFO:
• A new EnergyPak might not yet report the power level very accurately. This
will improve after a few full cycles of discharging (by riding) and recharging.
18Bike usage

4.4.2Best practices for riding range
For optimal riding range and to minimize wear of the moving parts on your e-bike, try to
make a habit out of the following best practices:
•Select an appropriate gear for the riding speed and pedaling speed (cadence).
Shift gears often. Choose a relatively low gear and high, but comfortable pedaling
cadence. This provides an optimal ratio between power output and energy
consumption in almost all riding scenarios.
Don't stay in one (high) gear. Setting off and riding at lower speeds in a high (heavy)
gear will result in higher energy consumption.
Release pressure on the pedals while shifting gears.
•Select the right assist level.
Let the " Smart Assist" function control the assist level automatically (availability may
vary by specification/country).
Choose the lightest manual assist level that you need.
•Ride in harmony with traffic and the environment.
Try to ride at a steady speed and keep the momentum going. Fewer decelerations
require fewer accelerations, which minimizes power consumption.
•Keep the load weight minimal.
Remove any items and/or removable accessories that you don't need.
•Keep the e-bike clean and in optimal technical condition.
Check and maintain tyre pressure regularly.
Check and maintain the drivetrain (chain, chainwheel, sprockets, etc.) regularly.
Always bring your e-bike to your dealer for the scheduled periodic maintenance.
4.5EnergyPak
4.5.1First use
A new EnergyPak is shipped in a protective ‘hibernate’ state. It must be activated before it
can be used. Usually, the dealer will have activated and fully charged the EnergyPak before
delivery. If not, you take the following steps to activate it:
• Push the energy level check button on the EnergyPak (see the topic on EnergyPak
power level indicator for details).
The LED indicator of the EnergyPak will not light up when it is in hibernate state.
• Connect the charger to the EnergyPak (see the topic on charging for details).
• Disconnect the charger from the EnergyPak.
• Push the energy level check button. The LED indicator should now light up.
• The EnergyPak is now activated.
Bike usage19

INFO:
• It is recommended to fully charge the EnergyPak before the first use. This
would automatically activate the battery.
• It is not possible for an EnergyPak to go back to ‘hibernate’ state once it is
activated.
4.5.2EnergyPak power level indicator
Power in the EnergyPak can be checked by
pushing the energy level check button. The
LED indicator on the battery will light up
with a 1 second delay.
NOTICE:
• Pressing the button more than once within 1 second will cause the indicator
to blink in a certain sequence. This is not a user function. To check actual
battery charge level, wait for the LEDs to stop blinking, then push the button
only once and wait a few of seconds for the LEDs to show the charge level.
• When an EnergyPak is connected to the bike, some 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.
• After a ride, do not leave a completely empty EnergyPak without charge
for an extended period. Try to make sure that it is at least partially charged
within 1 or 2 days.
• When weather conditions are bad (rain, snow, mud, sand, dust) it is
recommended to take out the EnergyPak after the ride and make sure the
connections are clean and dry before the next ride.
4.5.3EnergyPak removal & installation
The procedure for removal and installation of the EnergyPak can vary by the e-bike type
and model. Read and follow all instructions carefully.
CAUTION:
• An EnergyPak is relatively heavy. Take special care to support the weight of
the EnergyPak when unlocking/releasing the EnergyPak to prevent dropping.
