From time to time your bike may be exposed to conditions that could lead to water pooling in the frame.
Since prolonged exposure to water can cause damage to the internal electronics we recommend doing the following to drain any water that may be caught inside the frame:
Step 1 Locate the rubber port on the bottom bracket near the rear wheel
Step 2 Release the plug by lifting up the top of the tab
Step 3 This will allow this plug to flap open and drain any water that may be sitting inside the frame
Step 4 Close the tab before riding the bike again
