Maintenance Recommendations for All E-bike Components

I. Routine Maintenance Schedule

1. Pre-Ride Check

Battery: Verify charge level; keep it above 20% to avoid deep discharge damage.
Tires: Check tire pressure (20–30 psi for paved roads; 8–15 psi for off-road/snow) and inspect the tread for debris.
Safety & Electronics: Test front and rear lights, horn, and ensure both brakes engage firmly.

2. Monthly (or Every 200 Miles)

Drivetrain: Clean and lubricate the chain (perform more frequently if riding off-road or in the rain); measure for chain stretch.
Braking System: Inspect brake pad wear (replace if friction material is <1 mm) and check rotors for grease or contamination.
Cockpit: Clean the LCD screen and throttle contacts; test that the throttle returns smoothly without sticking.

3. Quarterly (Every 3–6 Months)

Motor Cut-off Switch: Test that the motor instantly cuts power when either brake lever is pulled.
Hardware: Check and torque bolts on the pedals, seatpost, handlebars, fenders, and kickstand.
Wiring: Inspect the main wiring harness and connectors for chafing; apply dielectric grease to waterproof seals.

4. Annual / Major Service (Bike Shop Service Recommended)

Suspension: Perform lower-leg service (replace oil and seals) for forks and rear shocks.
Hydraulic Brakes: Bleed the system and replace brake fluid (every 1–2 years, or immediately if levers feel spongy).
Bearings: Check for play in the headset, bottom bracket, and wheel hubs; clean and re-grease.

Component	Wear Limit / Replacement Indicator	DIY Difficulty
Battery	Capacity drops below ~70% of original (typically 3–5 years or 500–1,000 charge cycles). Stop use immediately if the pack is swollen or unusually hot.	★
Chain & Cassette	Replace the chain at 0.75% stretch. If stretch reaches 1.0%, you must replace both the chain and cassette to prevent skipping.	★★
Brake Rotors	Thickness falls below ~1.5 mm, or the rotor is severely warped and causes a pulsing sensation when braking.	★★
Tires	Tread is worn down to the indicator, sidewalls are cracked, or you experience frequent slow leaks (typically every 1,500–3,000 miles).	★
Motor & Controller	Frequent error codes, grinding noises on startup, jerky rotation, or extreme heat. Hub motors typically last 5–8 years.	★★

Motor continues running while braking: Extremely dangerous; stop riding immediately and replace the faulty motor cut-off switch.
Knocking or creaking from the front end: Indicates a loose headset or stem; re-torque bolts or replace bearings.
Clicking sound when pedaling standing up: Suggests a loose or dry bottom bracket; requires re-greasing or replacement.
Wheel wobbles or rubs the brakes when spinning: Indicates loose spokes or a bent rim; requires spoke tensioning and wheel truing.
