Heat makes brake fluid expand. If your brakes feel "sticky" or don't fully release, your fluid might be old or contaminated with moisture.
Summer Maintenance: Ensure you are using high-boiling-point fluid (like DOT 5.1 or high-quality Mineral Oil depending on your model) to prevent "brake fade" on long downhill descents.
Do I need to change my tire pressure for summer?
Yes. Hot air expands. If you set your PSI in a cool garage and then ride on hot asphalt or baking sand, your tire pressure will rise by 2–4 PSI.
Action: Check your pressure at the riding location to ensure you still have the grip you need for the terrain.
How do I keep my motor and controller cool during hill climbs?
Constant low-speed, high-torque situations (like technical rock crawling) create the most heat because there isn't enoughon-coming airflow.
Pro-Tip: Ensure your cooling fins (on the controller) are free of dried mud and debris. If you ride in extreme heat frequently, consider adding an aftermarket Heat Sink or a specialized cooling fan kit.
Is it safe to leave my bike in the sun while I'm at the beach or a cafe?
Try to find shade. Direct sunlight on theblack battery casingandLCD displaycan cause temperatures to soar well above 50°C (122°F).
The Risk: Extreme heat is the #1 killer of lithium battery capacity. If you must leave it in the sun, cover the seat and battery area with a light-coloured cloth or specialized bike cover.
Can I charge my battery immediately after a hard summer ride?
Avoid this if possible.After a heavy trail session, your battery cells are internally hot. Charging adds even more heat.
The 30-Minute Rule: Let the battery sit in a shaded, ventilated area for at least 30 minutes to "cool down" before plugging it into the charger. This significantly extends the long-term health of your lithium cells.
Why does my bike lose power on very hot days?
This is called Thermal Throttling. Your controller and motor have internal sensors. When they hit a specific temperature (usually around 80°C-90°C / 176°F-194°F), the system automatically reduces power to prevent permanent hardware damage.
The Solution: If you feel a power drop, ride at a steady, low speed to allow airflow to cool the components, or take a 15-minute break in the shade.
