The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.

The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design. The motor is built into the wheel hub itself, and the stator fixed solidly to the axle, and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.

The Netherlands has a fleet of 18 million bicycles.[77] E-bikes have reached a market share of 10% by 2009, as e-bikes sales quadrupled from 40,000 units to 153,000 between 2006 and 2009,[78] and the electric-powered models represented 25% of the total bicycle sales revenue in that year.[77] By early 2010 one in every eight bicycles sold in the country is electric-powered despite the fact that on average an e-bike is three times more expensive than a regular bicycle.[73][78]
With asthma, the commuter was just what I needed to get up these hills in the DC area without having an attack. With the 20 miles range, that gets me though my day, I can almost get about 35 miles in, since I only use the assist for hills, and I call any incline a hill. It came in two days, was very easy to install. I did it myself. It took me over an hour because I was scared, and watch the video over and over. Before I install this, I never did any work on my bike, not even changed a flat. When I do group rides, people notice that I'm no longer the last person up the hills and tell me to slow down! They are impressed that I was able to installed it myself. I brought this in Feb. 2017, had one problem with the on/off switch which customer service addressed, sent me a new switch and instructed me on how to install it myself. They actually sent two switches, other than that, I had no problems with it. Great customer service that stands behind their product, great product, equals happy customer.
The Ancheer Power Plus can be ridden in pedal-assist mode or fully electric. The removable battery can be charged on or off the frame in 4-6 hours and you’ll get up to 31 miles from a single charge (15 miles if you don’t want to pedal). It’s a great bike for short commutes and light off-roading, though if you’re tall, you may find the one-size-fits-all approach doesn’t fit you.

Known for not only their powerful line of mountain bikes and specialty bikes—cruisers to fat—Bulls also has a versatile line of urban models. The Cross E Wave comes as one of their more affordable options at roughly $2,800, but at 20 mph can still range for up to 134 in optimal conditions with everything you’d expect (fenders, lock, lights and adjustability). The entire family of Bulls e-bikes has specifications built for any scenario.
The final major consideration is what type of riding you will be doing. Are you going on an off-road adventure through the mountains? You’ll want a very different electric bike than you would need if you’re riding on paved roads the whole time. Most bike tours are going to be on paved roads, but you should always research the area in detail during your planning process.
Those buyers aren’t likely to get a major workout. Researchers from the University of Tennessee found in a study of walkers, ebike riders and traditional bike riders that those who completed a 4.43-kilometer hilly route on an ebike used 22 percent less energy than traditional bikers and 64 percent less than walkers, most likely because the ebikers got to the finish line faster than the others. But perks included higher levels of enjoyment and no need for a shower when they were done.
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider.[36][37] Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes,[38] have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging.[39] This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains.[40] The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines[41] created 18650 battery packs[42] are commonly used among Do-it-yourself ebike makers.

Simplicity powers the Gtech model, available in either a 20-inch “sports” crossbar frame or a 17-inch “city” step-through option. From using a carbon belt drive to a gearless system that allows a computer to adjust speed while pedaling, not only has Gtech streamlined the e-bike process, but they’ve also dropped the price to just north of $1,000. At a range of about 30 miles, this 35-pound bike offers a humble introduction to e-bikes.
The eBike stimulates our mobility and is one of the most agile, comfortable and simply smartest vehicles of our time. With positive impact on our health, environment, and society. The modern components and the freedom in design of the Bosch drive systems represent the foundation for a diverse choice from the bike manufacturers - regardless if it is a mountain bike, trekking, city, or a touring bike.
Cost: Good e-bikes are not cheap, and unlike most bikes, the costs associated with owning an e-bike don’t end when you hand over your credit card in exchange for a shiny new steed. The average cost of operating an electric bike is around $390 a year, including maintenance and charging. You’re also likely to need to change the batteries every 3-5 years so factor that into your costs.
Bulls electric bikes with Brose motors will always top the list for any long distance ride. Coming in with a huge 650 watt hour battery, Brose estimates that you can take these bikes over 100 miles on one charge easily. They also have 90 nm of torque, which will pop you right up hills even when you’ve got a full rack of gear in the front and the back.
In terms of design, the attention to detail is just exquisite. The extra long fenders ensure you’re not going to get wet going through puddles. The cafe lock is hidden well enough to not ruin the look. I do kind of wish that the battery and fork could be that lovely green color, but we can’t have it all folks. For you green haters, it does come in white and black too. There’s also an option for this cute little front carrier if you want to put a bouquet and a baguette in it.
If you are a regular bicyclist who wants to add some excitement to your rides or wants some help with those hills, a full sized electric bike is the way to go. If you are considering a bike as a means of transportation more than an outlet for amusement, then a smaller, folding electric bike is the convenient choice. In each category, consider the speed and range you want, as these factors impact price.
The F1-trained engineers at William Advanced Engineering assisted with the electrical parts and the result is a 250W motor that provides pedal assistance via the front hub – which is a highly unusual approach –  drawing power from a 300Wh battery pack that sits in a bag and goes on the front where the Brompton luggage rack would normally sit. You can also opt for a larger bag that holds both the battery and your spare suit or laptop or whatever. 
In a friction drive motor, a small, solid wheel rotates against the side of the tire in order to drive it. The first motorcycles used the same concept, with a motor mounted above the front wheel. The problem is that the drive rubs at the side of the tire. It's inefficient, and it quickly wears the sidewall away. Tires need to be replaced every couple hundred miles. For this reason, you'll seldom see electric bikes with this type of drive anymore.
There are two basic categories of electric bike, and their uses don't offer equal crossover value. The first category is essentially a normal bicycle that has been outfitted with an electric motor. These bikes are the same size as a standard bicycle, and handle almost identically, save for the obvious benefit of added motive power thanks to a motor and battery.
Of course the specs are nuts. Shimano Deore XT Shadow+ drivetrain, Magura MT4 hydraulic disc brakes, Mach 1 rims, and Schwalbe G-One tires make this not only an incredible commuter, but really a solid racing bike if you want to challenge another ebiker. The G-One tires I just love. They’re slick enough to keep you up to speed, but have a good amount of knobiness so that you can handle bad weather.
Bicycles featuring pedal power were developed during the subsequent decades of the 19th century, with the most emblematic example being the bicycle we know today as the Penny-Farthing. The bike was named based on the substantial difference in its wheel size resembling the larger and smaller Penny and Farthing coins, respectively. These bicycles were wildly popular among the well heeled upper classes of Europe and America despite their penchant for launching riders head first over the large wheel, not to mention their relative difficulty to mount and dismount.
The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.
The Ancheer Power Plus can be ridden in pedal-assist mode or fully electric. The removable battery can be charged on or off the frame in 4-6 hours and you’ll get up to 31 miles from a single charge (15 miles if you don’t want to pedal). It’s a great bike for short commutes and light off-roading, though if you’re tall, you may find the one-size-fits-all approach doesn’t fit you.
Thankfully, the Pendleton Somerby is an affordable option which, though not as high performing as some pricier e-bikes, offers a chance for a beginner or less serious cyclist to venture into the electric bike world. With a classic, elegant, low step through frame, getting on is as easy as possible. This is to all intents and purposes a city bike, from its look to the mudguards and chainguards that keep your clothes pristine, and the space for a luggage rack.

The Moterra is Cannondale’s biggest and baddest e-mtb and just looking at this thing you can see that it’s built to withstand some wicked downhills and big drops. With 130mm of front and rear travel, paired up with 27.5-inch wheels and trail-grabbing 2.8-inch tires, along with a KS LEV Integra Dropper Post make this pedal-assist mountain bike a great option if you want to climb farther to shred longer, but don’t want to lug your bike uphill for ages. The 250w motor, placed slightly farther forward than most other bikes to optimize weight distribution and handling, will give you a nice boost so you can enjoy the ride up and not be too gassed when you get to the top. After all, it’s all about the ride down, right?
