This phenomenon is similar to how certain lifestyle choices, such as smoking or tanning, can accelerate ageing in people.

The impact of extreme heat on batteries can manifest in several ways. Firstly, it can cause the battery to lose water faster, leading to ageing and an increased probability of overfilling. Secondly, high temperatures can result in power reduction or even a complete cut-out, although normal function should resume once the battery cools down. Additionally, extreme heat may cause loss of electrolyte, permanent cell damage, or even battery failure.

To prevent these issues, it is recommended to avoid using electric bicycles during peak temperature hours, opting instead for cooler times of the day, such as the morning or evening. When riding in hot weather is unavoidable, reducing overall speed, practising gradual acceleration and deceleration, and avoiding high-speed riding can help minimise heat buildup and manage temperature fluctuations. It is also crucial to avoid fast charging, especially under extreme conditions such as direct sunlight or peak temperatures.

Proper storage and charging practices are also essential. Batteries should be stored and charged indoors in a cool, dry place, away from direct sunlight. Using an adapted charger and avoiding high-power charging can further help to maintain battery health. Taking these precautions can help extend the lifespan of electric bicycle batteries and ensure safe and efficient performance.

  • Install mudguards to keep rain and mud off you and your bike, improving your overall riding experience.
  • Use waterproof panniers and bags to protect your belongings from the rain.
  • Avoid charging the battery immediately after riding in the rain. Instead, leave it to dry indoors for at least an hour or two before charging.
  • After riding in the rain, perform a quick clean and wipe down your e-bike. Pay special attention to "parts that move," such as the chain and brakes, and consider re-lubing the chain and drive train.
  • If your bike is exposed to heavy rain or submerged in water, remove the battery and check for any signs of moisture near the battery connectors. Allow the system to dry completely before reinserting the battery.
  • Check the controller casing, display, and control buttons for any water exposure or moisture accumulation, as these areas are crucial for managing power and functionality.
  • If you plan to store your e-bike outdoors, ensure it is not at risk of being submerged in water. Storing it in a dry place can help prevent corrosion and prolong its lifespan.
