🌞How to Properly Maintain Your Shengmilo E-Bike in Hot Weather?
As summer heat intensifies, proper usage and maintenance of your e-bike under high temperatures becomes increasingly important. For high-performance and technologically advanced e-bikes like Shengmilo, improper care in extreme weather may not only shorten the lifespan of the vehicle but also pose potential safety risks.
This article will guide you through battery maintenance, motor care, tire and brake inspection, riding habits, charging/storage suggestions, and regular maintenance tips to help you safely enjoy your Shengmilo e-bike during hot summer days.
1. Battery Care: Prevent Overheating, Swelling, and Aging
1.1 Avoid Direct Sunlight
The battery is the most important and sensitive component of the e-bike. Exposure to direct sunlight can increase the internal temperature, causing electrolyte evaporation or even battery swelling and fire hazards. We recommend:
-
Parking in shaded, well-ventilated areas;
-
Avoid prolonged exposure to the sun;
-
Use sunproof covers to reduce heat absorption.
1.2 Charge Properly
Charging in high temperatures requires special attention:
-
Charge during cooler periods such as early morning or evening;
-
Do not charge the battery in sealed or high-temperature spaces (e.g., car trunks, garages);
-
Avoid charging immediately after riding. Let the battery cool down for at least 30 minutes before charging.
1.3 Inspect Battery Regularly
Check if the battery case shows any deformation, swelling, or cracks. If abnormalities are found, stop using it immediately and contact Shengmilo support or a professional technician.
2. Motor & Controller Protection in High Temperatures
The motor and controller may also overheat in hot weather, which can affect power output or cause damage.
2.1 Avoid Long Periods of High Load
Activities like climbing steep hills, carrying heavy loads, or prolonged high-speed riding may overwork the motor. Suggestions:
-
Use Pedal Assist System (PAS) instead of full-throttle mode;
-
Avoid prolonged steep climbs;
-
Allow rest stops during long rides to cool down the motor.
2.2 Check Cable Connections
High temperatures may soften plastic connectors, loosening the wiring. Before each ride, inspect the connection between the motor, battery, and controller for looseness, wear, or corrosion.
3. Tire, Brake & Suspension Inspection and Maintenance
3.1 Check Tire Pressure
Hot weather causes internal air to expand, possibly resulting in tire bursts. Suggestions:
-
Regularly check tire pressure (refer to the pressure range in your Shengmilo manual);
-
If pressure is too high, release air slightly;
-
Check for signs of tire cracking or aging.
3.2 Maintain Brake System
Brake rotors may heat up in hot conditions, reducing braking performance. Suggestions:
-
Keep brake pads clean and remove any dust;
-
If braking feels soft or unresponsive, stop riding and inspect immediately;
-
Replace brake pads periodically, especially in mountainous or high-heat regions.
3.3 Lubricate Suspension System
Oil seals and springs in the suspension system can deform or leak under heat. Apply lubricant regularly and inspect for oil leakage on both front and rear shocks.
4. Riding Tips in Hot Weather
4.1 Ride During Cooler Hours
Avoid riding from 12 PM to 3 PM. Mornings and evenings are cooler and safer for both you and your e-bike.
4.2 Adjust Riding Habits
-
Use assist mode more often and reduce full-throttle use;
-
Control your speed to prevent brakes from overheating;
-
It’s normal for battery range to decrease slightly under heat, as efficiency drops.
4.3 Clothing & Protection
-
Wear breathable helmets;
-
Use UV-protective arm sleeves or cycling apparel;
-
Carry water and stay hydrated.
5. Charging & Storage Recommendations
5.1 Store in Cool, Dry Places
When not in use, store the bike in a shaded, dry, and well-ventilated place. Avoid sunlight or moisture exposure.
5.2 Recommended Battery Storage Temperature
Shengmilo batteries should be stored between 10°C–30°C (50°F–86°F). Avoid leaving the battery in extreme heat for long periods.
5.3 Avoid Storing in Car Trunks
Summer temperatures inside cars can exceed 60°C (140°F), which may lead to battery aging, swelling, or even fire hazards. Never leave the battery in the trunk under direct sunlight.
6. Regular Maintenance & Official Support
6.1 Perform Monthly Check-ups
-
Inspect bolts and screws for looseness;
-
Examine battery ports and cable wear;
-
Test brake responsiveness and motor performance.
6.2 Use Official Replacement Parts
When replacing components (battery, motor, controller, etc.), always use Shengmilo original parts to ensure safety and compatibility.
6.3 Contact Official Support
If you encounter any issues, contact Shengmilo Customer Service as soon as possible. We provide remote diagnosis, video assistance, and maintenance guidance.
Conclusion
Hot weather is a true test of both your e-bike's performance and your care habits. With proper usage and scientific maintenance, your Shengmilo e-bike can maintain peak condition and accompany you through every summer journey safely and reliably.
