Gentle cleaning: Wipe the frame and components with a damp cloth; avoid high-pressure water sprays on the motor, battery, or electrical parts.

Tire maintenance: Check tire pressure before rides, keep within recommended PSI, and inspect for damage or debris.

Brakes & folding joints: Test brakes frequently, check pads and disc/hydraulics, and tighten all folding-mechanism bolts, hinges, handlebars, and seat-post clamps.
-
Proper storage: For extended periods, remove the battery if possible, store indoors, and check tire pressure and battery charge before riding again.
