Run the simple “BRAKE” checklist before longer trips:

• Battery: Is it fully charged and ready to go?
• Risk: Are tires inflated to 55-60 PSI with no visible cuts, punctures, or damage?
• Alignment: Do brakes feel sharp and responsive? Are gears shifting smoothly without skipping?
• Knots: Are all bolts, screws, and quick-release levers tight and secure?
• Essentials: Do you have your patch kit (like tools for tire repair ), phone, and maybe the charger for peace of mind?

To extend your e-bike battery life:

• a. Charge the battery after each use and avoid full depletion;
• b. Apply the original charger;
• c. For long storage (weeks/months), keep it at 60-80% and check monthly;
• d. Don’t charge in freezing temps (below 0°C/32°F);
• e. Remove the charger promptly after full charging;

These tips help maintain peak performance for your removable lithium battery.

Lithium batteries self-discharge slowly. For long-term storage without riding, follow our e-bike care guidelines: Charge to 60%-80% and check monthly to prevent total discharge damage.

After wet rides, wipe down the frame, chain, and brake discs with a dry cloth to prevent rust. Even with IPX4 water resistance on your electric bike, prompt cleaning will contribute to lifespan.
