3.4 Inserting and replacing the battery
It is possible to replace the battery of your SO2. To do this, open the battery compartment with the key and remove the
battery pack. Insert the new battery as shown in the picture below and close the battery compartment again with the key.
3.5 Maintenance
Do not try to charge the SO2 when the battery is already full. This could diminish the battery’s capacity in the long run.
Check all screws before using the SO2, especially those of the handle bar, the brakes and the front- and rear wheel. Ensure
that all screws are tightened before you use the SO2.
Thoroughly clean the SO2 with a dry cloth after usage. The front and rear ball bearings must be lubricated from time to
time. Ordinary bicycle oil can be used. Oil the area where the axle runs into the wheel to ensure better durability.
