What exactly is an electric bike? How can they be used for transportation and why do they make financial sense? These are some of the questions my site http://electricbikereview.com and this channel aim to help you answer. This particular video provides an overview of the Easy Motion Neo Jumper ebike and then follows me on an actual commute to work in Austin Texas.
By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle. Schnepf's invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.

There are various kinds and classifications of electric bikes on the market, but the more common type is the Class 1, or pedal assist, bikes which have motor units that are activated by pedaling and are limited to lower speeds. In the US, Class 1 electric bikes, the type tested and reviewed here, are limited to a top speed of 20 mph and their motors are designed with a speed governor to regulate this. These types of e-bikes resemble modern mountain bikes, but they have significant battery packs and small motor units integrated onto and into the frame design. The e-MTB pedal-assist motor is typically built around the bottom bracket and provides varying levels of pedaling "support" directly into the drivetrain while the cranks are turning. Most drive unit systems offer several support settings that provide pedal assistance between 25% and 100% of the user's pedaling input.
Mountain electric bikes can even be used for commuting to work or going to the grocery store. When choosing a mountain eBike, make sure that you pick one that has at least 500 to 750 watts of power. Having a powerful motor to assist you on the trail will keep your legs from being sore at the end of the day. This will ensure that you get the most out of your bike and be able to drive across rocks and logs with ease.
E-bikes use rechargeable batteries and the lighter ones can travel up to 25 to 32 km/h (16 to 20 mph), depending on local laws, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany as of 2013, they are gaining in popularity and taking some market share away from conventional bicycles, while in others, such as China as of 2010, they are replacing fossil fuel-powered mopeds and small motorcycles.
