Electric Bicycle https://www.alibaba.com/Electric-Bicycle_p1221?spm=a27aq.13891069.1148563840.33.374c229fVpJEuo E-bike use was shown to increase the amount of physical activity. E-bike users in 7 European cities had 10% higher weekly energy expenditure that other cyclists because they cycled longer trips. E-bikes can also provide a source of exercise for individuals who have trouble exercising for an extended time (due to injury or excessive weight, for example) as the bike can allow the rider to take short breaks from pedaling and also provide confidence to the rider that they'll be able to complete the selected path without becoming too fatigued[57] or without having forced their knee joints too hard (people who need to use their knee joints without wearing them out unnecessarily may in some electric bikes adjust the level of motor assistance according to the terrain). A University of Tennessee study provides evidence that energy expenditure (EE) and oxygen consumption (VO2) for e-bikes are 24% lower than that for conventional bicycles, and 64% lower than for walking. Further, the study notes that the difference between e-bikes and bicycles are most pronounced on the uphill segments. There are individuals who claim to have lost considerable amounts of weight by using an electric bike A recent prospective cohort study however found that people using e-bikes have a higher BMI than those using conventional bikes By making the biking terrain less of an issue, people who would not otherwise consider biking can use the electric assistance when needed and otherwise pedal as they are able E-bikes can be a useful part of cardiac rehabilitation programmes, since health professionals will often recommend a stationary bike be used in the early stages of these. Exercise-based cardiac rehabilitation programmes can reduce deaths in people with coronary heart disease by around 27%.
