Most consumers want an e-bike that will accommodate its motor without being too cumbersome and will remain stable in spite of its electronic components. Some consumers want only the most basic of e-bike features, including lights, a cargo rack/basket, and a water bottle holder. Others are focused more heavily on safety features, such as brake type. And still others are concerned with and portability.
Globally, electric bicycles outsell electric cars by a wide margin. An estimated 29.3 million e-bicycles were sold in 2012, with perhaps 90 percent of those selling in China, which has more electric bikes than cars on its roads. E-bicycles are popular in Europe, too, selling about 380,000 a year in Germany and 175,000 in the Netherlands in 2012. By comparison, about 120,000 electric cars were sold worldwide.
I like having both options. The throttle is great for getting a quick burst of speed, like when going through an intersection. It is also good when you are riding in a situation that requires you to be able to vary your speed quickly. I like the pedal-assist when riding on open stretches of road. On my Pedego Interceptor I can change the pedal-assist mode very easily so if I need to drop down from Super Girl #5 to Modest Mouse #2 I can do that quickly.
Rear hub motors are also popular. Some owners suggest they make the back of the bike feel a bit heavy (the battery is often back there, too), but balance is still good. In many ways, this is rear-wheel drive like you get with a scooter or motorbike. The rear hub looks larger than usual, but in profile, it looks much like an ordinary bike.
In this section, we see the requirements for drivers licences for various vehicles. The the one to take note of here is that if you operate as a “moped” (30-MPH) then you need not only a drivers license, but one with a motorcycle endorsement. But as a motorized bicycle, (20-MPH) you do not need any drivers license. You only need to be 16 years old for the “bike”.
The oldest patent for an electric bike I’ve been able to find at the US Patent and Trademark Office is this one, by Ogden Bolton, Jr. of Canton Ohio, which was filed in September 1895 and granted three months later. You can see from these original diagrams that it bears an amazingly close resemblance to modern electric bikes. In the general picture on the left, you can see there’s a hub motor on the rear wheel (blue), a battery suspended from the frame (red), and a simple handlebar control to make the thing stop and go. In the more detailed cutaway of the hub motor on the right, you can see there’s a six-pole magnet in the center (orange) bolted to the frame and an armature (made from coiled wire, yellow) that rotates around it when the current is switched on. It’s quite a hefty motor even by modern standards; Ogdon mentions “a heavy current at low voltage—for instance, to carry one hundred amperes at ten volts.” So that’s 1000 watts, which is about twice the power of a typical modern bike hub motor.
This Electric Bicycle kit includes everything needed(except battery) to convert your standard bike into a top-of-the-line performance electric bike. Crank speed sensor for pedal assist. 36 V 500 W super power brushless gearless hub motor.
Add a device to control speed. One example is a three speed switch. Some controllers have a plug for it, or there are types that just modify the throttle signal. If your controller comes equipped with a cycleanalyst plug, then the CA can have its speed limiting function set to 20-MPH. Lastly, some controllers have a jumper wire that limits potential speed. In most cases this jumper wire, when connected, will result in speed a lot slower than 20-MPH. So that may not be the first choice. However you get it done, it beats having to comply with the moped laws, particularly if you have no drivers license.
Both land management regulators and mountain bike trail access advocates have argued for bans of electric bicycles on outdoor trails that are accessible to mountain bikes, citing potential safety hazards as well as the potential for electric bikes to damage trails. A study conducted by the International Mountain Bicycling Association, however, found that the physical impacts of low-powered pedal-assist electric mountain bikes may be similar to traditional mountain bikes.
One of the most powerful, fastest accelerating, quietest, and beautifully designed electric bikes I have ever tested, premium drivetrain and custom battery. Surprisingly lightweight and well balanced front to rear considering the large 750 watt hub motor,……
Electric bicycle (e-bike) laws are different in every state, and can be confusing for consumers, retailers, and suppliers. The Bicycle Product Suppliers Association and PeopleForBikes have a partnership to make riding an e-bike easy and accessible for all.

“I used to whip around corners on horseback with the wind in my face,” said 27-year-old Marino, who lives in Torrance, California. “It hurt not to have that anymore; not to feel myself riding anything.”
