Notes on the e-bike
5 Notes on the e-bike
5.1 Differences between a bicycle and
an e-bike
The additional components of the electric drive constitute the major
differences between a conventional bike and an e-bike�
– The e-bike is significantly heavier and its weight distribution is
different
from conventional bicycles� This results in different
handling�
– The drive has a significant effect on braking characteristics�
– E-bikes require greater braking forces. This may result in
greater wear than with conventional bicycles�
– The electrical assistance will increase your average speed�
• You should therefore cycle attentively. Keep in mind that
other road users must get used to the increased speed of
the e-bike�
– The bike's handling and braking as well as handling of the
rechargeable battery and charger require an appropriate level
of knowledge�
• Familiarise yourself with the characteristics of your e-bike
even if you already have some experience with electrically
power-assisted bicycles (see Chapter “Before each ride”
on page 20)�
5.2 Functionality
The drive only provides you with riding assistance when you pedal�
The intensity of assistance is automatically adjusted depending
on the selected riding mode, the pressure applied when pedalling,
the load and the speed� The drive assists you up to a speed of
25 km/h.
The A-weighted emission sound pressure level at the height of the
bike operator’s ears is less than 70 db(A).
5.3 Range
The drive is an assistive motor� The range is affected by your ped-
alling intensity�
• Set the assistance as low as possible�
The lower the pedalling frequency of the pedal drive the higher the
energy requirement for the drive.
• Use the gear shift as you would without assistance.
• For inclines, head wind or a heavy load, use the lower gears
of the gear shift�
The drive requires a large amount of energy when starting.
• Always start in a low gear and apply as much pressure to the
pedal as possible�
• Before travelling uphill, switch to a lower gear in time.
• Ride with foresight to avoid any unnecessary stops�
The energy consumption will increase with high loads�
• Do not transport any unnecessary loads.

16
Notes on the e-bike
Lack of care and maintenance may reduce the range.
• Handle the e-bike with care and observe all notes regarding
the rechargeable battery in this user manual�
• Check the tyre pressure regularly.
• Comply with the maintenance intervals.
Temperatures below +10 °C may negatively affect the perfor-
mance of the rechargeable battery during operation. When you
are not using your e-bike:
• At low outdoor temperatures, take the rechargeable battery
out of the holder and put it in storage (see Chapter “Storing
the rechargeable battery” on page 17)�
• Only put it back in the holder directly before cycling.
5.4 Cycling with an empty rechargeable
battery
If the rechargeable battery is completely used up during the ride,
you can use your e-bike as you would a normal bike (see Chapter
“Charging indicator” on page 25)�
Note: If the battery charge has been used up, the drive will switch
off� The lights will be supplied with energy for another 2 hours�
5.5 Drive overheat protection
CAUTION
The drive and rechargeable battery can become very hot
if a fault is at hand. You could injure yourself in the event
of contact with your skin�
Risk of injury!
• Do not touch the drive and rechargeable battery.
The drive is automatically protected against damage caused by
overheating. If the temperature of the drive is too high, the drive
will automatically switch off�
• To prevent the drive from overheating, set a low level of assis-
