5   Assistance by the electric motor

5.1   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 effort 

The motor adapts to the force you apply. If you 

pedal harder, e.g. uphill or when setting off, 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 effort (1 : 2). 

With the "

medium assist level / MID

", the power 

delivered by the motor matches your own effort 

(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 off on your Pedelec, the assistance increases 

as you build up your speed until your bike reaches its 

maximum speed of roughly 19 km / h. The assistance 

then reduces automatically and switches off at roughly 

25 km / h. This happens irrespective of the gear you are 

using.

Distance

The distance you can travel using the power assist with 

the battery fully charged depends on several factors:

•

Ambient temperature 

If it is colder, you will travel a shorter distance 

with the same battery charge. 

To maximise the distance you can travel, keep the 

battery in a heated room so that it is at room tem-

perature when you fit it on your Pedelec. 

As the battery discharges when the motor is in use, 

it generates enough of its own heat to not lose too 

much of its power at low temperatures.

•

Selected assist level  

If you want to cover a large distance assisted by 

the motor, select the lower gears, i.e. the ones 

that are easier to pedal. Also change to 

"low assist 

level / LOW"

.

•

Handling 

If you are riding in gears that are harder to pedal 

and select a high level of assistance, e. g. when 

riding uphill, the motor will provide support with 

plenty of power. However, this leads to higher con-

sumption, as with driving a car at high speed on 

the motorway. You will therefore have to recharge 

the battery sooner. You can conserve energy when 

riding your bike not just by turning the pedals, but 

also by applying even pressure throughout each 

crank revolution.
