Electric bikes are rapidly gaining popularity both in the United States as well as many other countries around the world. Infrastructure development and a culture of awareness are contributing to this rise. And due to concerns about climate change, there is a move toward alternative transportation vehicles. If we consider the importance of fitness and the role that bicycles can play in it, it is no wonder that e-bike purchases will continue to increase for the foreseeable future. Are the risks of electric bike fires real?
Like electric automobiles, most electric bicycles use lithium-ion batteries. Battery technology advances have made this type of battery very common since it can store a lot of electricity efficiently in a relatively small package. There have been a number of reports around the world of lithium battery fires in these bikes and even some resulting in death. As you might expect, these fires can happen rapidly and are difficult to extinguish with water. Battery fires are often caused by damage to the battery itself or faulty manufacturing. In order to decrease the chances of a battery fire, consider these recommendations:
- Check the battery regularly for signs of damage especially if you have been in an accident. If there is visual evidence of damage, replace the battery and do not try to charge it
- Only buy bikes with batteries that come from reputable manufacturers
- Pay close attention to the manufacturer’s charging recommendations
- Only use chargers that are approved by the manufacturer
- Keep the battery in a cool place away from heat sources or direct sunlight
- Do not charge the battery overnight or unattended
- Charge outside if possible
- Do not charge in a small closed space
- If the battery emits a strange smell or gets very hot while charging, stop immediately
- Keep a fire extinguisher near where you will be charging.
- Use an extinguisher specifically designed for lithium fires
- Type D or ABC fire extinguishers are the next best
- Water is a last resort if an acceptable extinguisher is not available
In the unlikely event of a fire:
- Get off the bike immediately if you are riding and call your local fire emergency number
- Extinguish the fire if possible
Battery fires do happen, but considering the number of e-bikes that are being sold worldwide, they are relatively rare. Remember the old adage “You get what you pay for”. Don’t buy an e-bike just because it is cheap. They may be cheap for a reason that makes the bike unsafe. Regardless of your budget only buy a bike made by a known, reputable manufacturer that uses parts made by reputable suppliers.
