9.4 Tips
9.4.1 Range
Various factors determine how far you can go with your battery:
When you go on a long trip it is worth taking a spare battery
or battery charger with you.
Ride profile: You need the most power in the highest ride profile
(Dynamic). The range becomes shorter.
Select the ride profile in line with the routes you ride. For
a leisurely tour with friends at the weekend, the "Relax"
assist level is the right choice. If you often cycle at greater
speed (such as to work), the "Dynamic" setting can inject
the necessary pace.
Assist mode: You consume the most battery power in the highest assist
mode. The range decreases, the higher the selected assist mode.
Vary the assist modes you use. If there is a tailwind when
going downhill or on the level, you can still go fast with a
lower assist mode.
Tyre pressure: If the tyre pressure is too low it is harder for the tyres to
rotate. The drive unit needs to provide more assistance and the range
decreases.
Riding style: A low pedalling speed combined with high gears results in
high power consumption.
Change down in good time to maintain constant cadence,
especially when starting.
Your fitness level: The fitter you are, the less assistance you will need.
Total weight: The lower the total weight supported by the bike, the easier
it will be to ride  VI.I Overall weight Page
Outside temperatures: The lower the outside temperatures (e.g. cold in
winter), the shorter the range.
Insert the battery just before starting off with your pedelec.
This way you prevent low temperatures shortening the
range.
Battery capacity: A much shorter service life after the charging process
indicates that the battery has lost considerable capacity.

The battery may have to be replaced. Discuss how to
proceed with your cycle dealer.
