I've had folding bikes in the past and lovethe convenience of being able to throw my bike into my car.The e-bike market is ready to go mainstream in the U. S．. The price for e-bikes has come down greatly in recent months. At one time, most e-bikes with good components and proper weight were in the $ 3,000 range. Now you can find reasonable quality e-bikes in the $ 1,000 range. With gas prices at all-time highs，e-bikes are an attractive, low-cost option to gas efficient vehicles.E-bike owners are finding that they are great for commuting(上下班往返) to work，as traditional bikes can be a problem with office dress and sweat.People who use e-bikes range from commuters to casual cyclists who like a little help with hills and wind, to those who decide to save money on buying a motor bike. These are not for the serious road cyclist or professional mountain biker.If you're considering buying an e-bike, it pays to do some research first. Cheaper e-bikes are going to be heavier and have less battery-power. Higher priced bikes will be made from lighter materials and have better batteries.Another consideration is local motor vehicle laws. For example，according to U．S. federal law，as long as your electric bike is under 750 watts and does not go over 20 MPH then it is a bicycle and not a motor vehicle. Most consumer e-bikes in the $ 1,000 range don't fit the motorized vehicle description.文章大意：电动车作为一种环保、方便的交通工具越来越受到人们的欢迎。
