- Charge the 48V battery correctly—avoid full depletion and store at 30–80% charge.
- Clean and lubricate the drivetrain regularly, especially after sand, mud, or snow rides.
- Inspect and test hydraulic disc brakes often; replace pads when braking weakens.
- Tighten key bolts monthly (stem, handlebars, seatpost, wheels, rack, axles) for safety.
- Rinse off dirt, salt, and debris after rides to protect frame and components.
- Keep electrical parts dry and clean (display, wiring, battery mount, charging port).
- Check tires for punctures, sidewall wear, and embedded debris before each ride.
- Monitor pedal assist and motor response for smooth, consistent performance.
- Schedule a professional e-bike tune-up every 6–12 months for full system checks.
