2. Motor
Hermansen e-bikes are equipped with an intelligent,
brushless and small 250W rear hub motor with built-
in controller, sensor and Bluetooth communication
module. It is a silent <50dB motor with a maximum
motor assisted speed level of 25 km/hr in compliance
with EU regulation. The motor has over-temperature,
overspeed, overload, undervoltage, overvoltage and
other protection functions.
The motor is powered by an external bottle shaped
battery placed on the e-bike’s seat post and
controlled from a Bluetooth connected smartphone
app. For more information about the battery please
see chapter 3. For more information about the app
please see chapter 4.
Turning the motor on and off
When you connect the power cable from the motor
to a charged battery, the motor is turned on. If
you disconnect the power cable from the battery
the motor turns off. The motor also turns off if the
connected battery is discharged.
If the e-bike is left idle with the power cable still
connected to a charged battery, the motor will go into
sleep-mode after being inactive for five minutes to
save battery. When you start riding your e-bike again
the motor turns back on.
Activating motor assistance
The motor has a pedal action sensor designed to
register when you turn the pedals. The motor only
provides assistance when you pedal, and when
you stop pedalling the motor stops supporting too.
It makes pedalling easy and feels like riding with
constant tail wind.
DANGER!
Note that a pedelec moves
immediately when you put your foot on
the pedal and it sets in motion. Always
first pull the brakes and then get on
the e-bike. Otherwise an unexpected
move can lead to hazard and injury.
Motor assist settings
The motor has four power assist settings which you
set from the smartphone app:
• Off: Zero power assist
• Eco: 40% of maximum power assist
• Tour: 70% of maximum power assist
• Sport: 100% of maximum power assist
When you start pedalling the motor starts to assist
you if you have chosen the Eco, Tour or Sport
setting. It will support you until you reach the allowed
maximum motor assisted speed level of 25 km/h. You
may also set the maximum motor assisted speed at
a lower level on the app. This means that the motor
will cut off at this speed level but start assisting your
again if your speed falls below 25 km/h. For more
information about how to set up the motor from the
app please see chapter 4.
Riding your e-bike
Before riding your e-bike for the first time you must
set up various motor and riding parameters in the app.
For more information about how to set up the motor in
app please see chapter 4.
The default power assist setting is Eco. This means
that if the e-bike has been turned off it will default to
the Eco setting when connected to a charged battery
again and you start riding your e-bike.
If your bike is in sleep-mode and you start riding your
e-bike again, the motor will reactivate and start to
support you with the latest chosen power assist level.
If you choose the Eco power assist setting, the
motor may not be able to get you to reach 25
km/h, depending on riding conditions, riding style,
cargo load and rider weight, unless you pedal with
considerable power yourself. In this case switch to
a higher power assist level if you want to increase
support and speed.
• When driving uphill and headwind, you can
increase the power assist level to get an easier
ride.
• Riding uphill for a long time with maximum
motor assist may activate the motor’s overheat
protection in which case the app will show an
overheat warning message. If this occurs, turn off
the motor and wait until the temperature drops.
When the temperature drops, the motor will
automatically return to working normally.
• After riding, store your e-bike in a proper place.
• If the bike is stored for a long time, disconnect the
power cable and avoid storing the e-bike near a
heat source.
Cleaning
Never use pressurised water, spray or steam to
clean your e-bike because water can be forced into
sealed areas and damage components like the motor,
cassette body, bearings and other parts.
