12. NOTES ON BATTERY DURATION
- Battery duration may vary significantly (from 20 to 150 km) depending on the type of use and the age of
the batteries (on average, battery duration is reduced by approx. 40 % after 3 or 4 years).
The main factors that affect battery duration are:
Factor
Relevance Effect on duration
• Weight of rider and load
*
Decreases as the weight of the rider and any accessories increases.
• Tyre pressure
*
Decreases as the tyre pressure decreases.
• Type of road surface
* *
Decreases significantly when riding on mud, damp grass, or irregu-
lar surfaces, increases on smooth surfaces.
• Climbing
* * *
Decreases as the gradient increases.
• Gear ratio
* *
Decreases when using “harder” ratios (e.g. 11
or 13), increases when
using “easier” ratios (e.g. 36th).
• External temperature
*
Decreases by approx. 15% if the temperature falls below 0°C.
• Speed
* * *
Decreases exponentially as the speed increases.
• Wind
* *
Decreases significantly in the presence of a head wind in excess of
15 km/h, negligible variations at lower wind speeds.
• Assistance setting
* *
Decreases as the requested pedalling assistance level increases
(long duration in “Cruise” setting, short duration in “Sport” setting).
• Stationary start
* *
Decreases the more often the “stop&go” function is used, since the
bicycle consumes almost 3 times as much power during the acceler-
ation phase as when it is travelling at a constant speed.
