2.1 Charging instructions
Read the following instructions and warnings carefully before using the
E-bike. The manufacturer is not responsible for accidents or malfunctions
caused by improper use of the E-bike or parts of the E-bike:
• Fully charge the battery pack once before the first use of the bike.
• Every battery runs down over time. This process is called ‘self-
discharge’. A battery pack that is empty and that is not charged can
reach deep discharge due to self-discharge within two months, causing it
to become defective. The warranty is void in the event of deep discharge.
• The battery pack does not need to be completely empty before charging.
The battery pack will remain in good condition if you charge the bicycle
after every use (regardless of the trip distance). Once the battery is fully
charged, charging stops automatically. The light on the charger continues
to be lit green.
• You can leave the charger connected for long-term storage. If this is not
possible, charge the battery pack fully and disconnect the charger from
the battery pack. Charge the battery pack fully at least once every two
months.
• Ensure that the battery pack remains within the temperature limits given
below. This extends the lifespan and increases the performance of the
battery pack. Furthermore, charging or the power assistance will not
work outside the temperature limits.
