When successfully connected, the four green LED lights next to the charging socket will
turn on and indicate the level of charge in the battery. The charge level is measured in 25%
increments.
When charging is complete, disconnect the charging plug from the battery charging socket
and unplug the charger from the outlet.
Follow the steps outlined in Section 10.3.1 in this User Manual to reinstall the battery.
WARNING! Take care not to drop the battery when removed from the
bicycle. A hard enough impact can potentially damage the battery which may
or may not be visible from the outside but can render the battery unsafe.

At approximately 10% (depending on cell temperature and other factors) battery charge
remaining, the system will start to reduce the amount of motor support to ensure continuous
assistance at lower charge levels. At 5 - 3%, the system switches off motor support, leaving
the bicycle powered on. This not only supports battery health and lifetime, it also allows you to
keep any wired lights powered for about 2 hours. The timing of the motor shut-off may slightly
vary depending on cell temperature.

If your bicycle is at a standstill for 15 minutes or longer, the system will turn itself off to save
power. In order to continue riding with support, you have to turn the system on again.
