Puncture and removal of
wheelset
In the event of a puncture, the tire change is sim-
ilar to that for a normal bike. If you are not sure
how to change a tire, please contact a Stromer
specialist retailer.
Before any maintenance work, please re-
move the battery from the battery box. Never dis-
connect or connect a plug while the battery is in
the battery box. You thereby avoid the risk of an
electric shock and of injury.
Front wheel
To remove the front wheel, loosen the thru axle
with a 6-mm hexagonal wrench and pull out the
thru axle.
Rear wheel
• To remove the rear wheel, first shift to the
smallest sprocket (high gear).
• Loosen the thru axle with a 5-mm hexagonal
wrench and pull out the thru axle.
• Pull the gears back slightly.
• Lift the ST2. With a light knock on the wheel
with your palm from above, it should detach
from the frame.
• Pull on the small silver tab to disconnect the
plug to the motor.
You can now remove the wheel from the fork or
chain-stay and rectify the tire damage.
In order to install the wheel again, proceed in the
reverse order of the removal. The torque of the
thru axles is 20 Nm.
Warning notes
If the motor is under heavy load for a longer
period, e.g. on long ascents, it may overheat. In
order to avoid burns, make sure that you do not
touch the engine with your hands, feet or legs.
In order to avoid a life-threatening electric shock,
make sure that no objects can be held through
openings in the ST2.
Make sure that the ST2 cannot be used by third
parties without your consent.
