Assistance By The Electric Motor; Operating Principle Of Assistance - Panasonic Pedelec Mode D'emploi

5 Assistance by the electric motor

If your Pedelec is equipped with hub gears, you may
have to take more load of the pedals when changing
gears than you would normally do when riding your
conventional bike. This is due to the additional power
output of the electric motor. The hub gear system
contains a device that protects it against gear shiting
operations under excessive loads in order to preserve
the gear unit in the hub.

Operating principle of assistance

The motor provides support as soon as you switch the as-
sistance on and start pedalling.
The thrust delivered by the motor depends on three factors:
• Your own pedalling efort
The motor adapts to the force you apply. If you
pedal harder, e.g. uphill or when setting of, the
power sensor detects this and increases the thrust
accordingly. However, the thrust is limited by the
maximum motor output.

• The assist level you have selected
With the "high assist level / HIGH" the power deliv-
ered by the motor is double your own efort (1 : 2).
With the "medium assist level / MID", the power
delivered by the motor matches your own efort
(1 : 1). With the "low assist level / LOW / ECO", the
power delivered by the motor is half your own ef-
fort (1 : 0.5).
• The speed at which you are currently travelling
When you set of on your Pedelec, the assistance
increases as you build up speed until your bike
reaches its maximum speed of roughly 22 km / h.
The assistance then reduces automatically until
you reach a speed of roughly 25 km / h when it
switches of. This applies for the largest gear only.
In all other gears, the motor switches of earlier,
depending on the gear ratio.
