Today’s health = The popularity of electric bicycles is increasing day by day. Electric bicycles are used not only for commuting to work, but also for various aspects of daily life, such as weekend outings and grocery shopping. This is because you can travel long distances without any burden and climb high hills with ease. According to the Korea Smart E-Mobility Association (KEMA), domestic electric bicycle sales last year amounted to 107,000 units, a growth of approximately 346% compared to 2018 (24,000 units). Do electric bicycles have a ‘real’ exercise effect?
In general, electric bicycles are divided into types depending on the motor drive method. It is divided into the PAS method, in which the motor is driven when you step on the pedal, the PAS method, in which the throttle is operated without stepping on the pedal, and the PAS-throttle combined method equipped with these two methods. No matter what method you use, your muscles are used when riding an electric bicycle. Pas-type electric bicycles may require less force than regular bicycles, but muscles such as hips and thighs are used when pedaling. Even if you don’t pedal, you use muscles throughout your body, including your shoulders and arms, when you hold the steering wheel and maintain balance.
In fact, Rhonda Martin, a middle-aged American woman, weighed 207 kg in the past, but succeeded in losing 127 kg by riding an electric bicycle. Of course, many factors other than the electric bike may have played a role in Rhonda’s diet, but she revealed that the electric bike was a huge motivator for her to exercise. She says she can move more freely than when she walked, burns calories and regains her confidence when socializing.
A British study found that electric bicycles help increase physical activity by allowing users to ride long distances with less fatigue than regular bicycles. Even those with weak physical strength naturally have opportunities to be active in outdoor activities. Another study conducted in 2019 found that electric bicycles were beneficial for mental clarity. According to a study published in PLoSOne, an online journal from the American Public Library of Science, a survey of 100 adults aged 50 to 83 found that those who regularly engaged in cycling exercise, such as using an electric bicycle, had better mental health and better mental health than those who did not. There was a positive effect on cognitive function, etc.
Wearing safety equipment is essential. Electric bicycles can achieve high speeds with little force, so the risk of accidents is high. You should minimize possible injuries by wearing a helmet, wrist and knee pads, etc. It is best to choose a helmet that is strong against impact, protects your head, and is light so it does not interfere with exercise. Be careful if you wear a hat, headphones, or bandana under your helmet, as the helmet may easily come off and cause injury.
Meanwhile, the number of electric bicycle battery explosion and fire accidents is steadily increasing overseas. The New York Times reported that the number of people who died from electric bicycle fires is increasing, from 5 in 2019 to 9 in 2022, and to 14 as of September this year. The cause of the fire was found to be an uncertified lithium-ion battery. According to foreign media such as the Sydney Morning Herald on the 4th, there was a lithium-ion battery explosion in a hostel room in Sydney. CCTV footage from the hallway showed the room bursting into flames as the battery exploded. Sydney fire authorities believe the fire occurred when a lithium-ion battery that was being charged inside the hostel room exploded.
