Essential E-Bike Maintenance Guide

Core care, inspection routines, and cleaning tips for beginners.

1. Brakes & Safety Systems

Brake Adjustment: Check lever travel regularly. If the lever feels spongy or pulls all the way to the handlebar, adjust the cable tension or replace worn brake pads. For hydraulic systems, inspect hose connections for fluid leaks.
Tire Pressure: Maintain proper PSI to reduce rolling resistance and boost battery range. Under-inflated tires increase puncture risks, while over-inflated tires compromise grip and riding comfort.

2. Motor & Battery Health

Motor Fasteners: Periodically check hub motor axle nuts and torque washers to ensure they remain tight. Wipe away grit or mud near axle seals after riding on rough terrain.
Battery Care: Practice "shallow charging"—recharge when capacity drops to 20%–30%. Allow the battery to cool down for 20 minutes post-ride before plugging it in, and avoid charging in direct sunlight or damp environments.

3. Drivetrain & Chain Care

Cleaning & Lubrication: Regularly remove grime and old grease from the chain and cassette using a dedicated brush or rag, then apply a small drop of bike chain lube to each roller.
Wipe Excess Lube: After applying oil, rotate the pedals to let it penetrate the links, then wipe off any excess lube on the surface to prevent dust buildup.

Weekly Checks: Check tire PSI levels and clear debris embedded in tread grooves.
Before Every Ride: Test brake response by squeezing levers and pushing the bike forward—wheels should lock instantly without squealing.
Monthly Inspections: Inspect wiring harness connections for wear, loose plugs, or exposed insulation. Verify bolt tightness on handlebars, axle nuts, stem, and seatpost clamps.

Never Use High-Pressure Washers: Avoid spraying high-pressure water directly at the controller, LCD display, battery terminal connections, or motor hubs to prevent electrical short circuits.
Wipe Down Method: Clean the frame with a damp microfiber cloth and mild soap, then thoroughly dry all metal and electrical contacts.
Long-Term Storage: If storing the bike unused for weeks, keep the battery charged to 50%–70% in a dry, room-temperature environment and top it up once a month to prevent deep discharge damage.
