Fully charge your battery before your first ride and then after any operation, especially after long-distance riding.
Park the e-bike where an electric outlet is available. With the battery off, insert the round charging plug of the charger into the charging port on your e-bike frame, and then plug the other end into a standard 100-240 volt AC outlet.
When the charging indicator turns red, the battery is charging. When the charging indicator turns green, charging is finished and the battery is fully charged.
It takes up to 6 hours to fully charge a 10Ah battery pack.
When the charging is finished, unplug the electrical plug from the wall outlet first, then disconnect the charging plug from the e-bike.
