Lower the voltage.  Depending on the battery, the first block or two of riding might do the trick.  If your battery drops voltage fast, you might be a lot slower than 20-MPH for 98% of your ride. I’d call that close enough if that is the case.  Or maybe I can just charge my battery to a lower voltage.  Maybe if I charge it to 40 volts instead of the normal 42V-44V, I won’t be quite so fast.  That could work if my battery still gets me going 23-MPH for too long to fudge it.

Some people will want their e-bike to appear like a normal bike just to avoid any possibility of having a problem. To me, this is not needed if you are riding a street legal e-bike. But this brings up a persistent problem in some places.  E-bikes that look like gasoline powered scooters. Many riders have encountered police that cannot be convinced that they can fit the legal definition for a bicycle.  Whether they are bicycles or not is defined by the local motor vehicle codes.  Or, they may not.  In some states, there is no such thing as an e-bike defined in the codes.  Either way, you can encounter police who either don’t know their e-bike law, or just ticket you because of their opinion about e-bikes that look like scooters. Cops ticket, Judges sort it out later. Looking like a normal bike and staying under the police radar can save you some trouble. If you have a scooter type e-bike, then it’s worthwhile to know the law, and possibly even carry copies of the law that makes your bike a legal bicycle.

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.

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.

The Japanese giant, which manufactures everything from motorcycles and musical instruments to personal water scooters and motorboats, will begin selling Yamaha Power Assist Bicycles through U.S. dealers in 2018.

Brush motors are common because they’re durable and rather inexpensive to produce. However, modern brushless motors are lighter, smaller, and more powerful than brush motors, and they can be almost silent. E-bikes with brush motors cost more, but they require no maintenance. As a result, electric bikes now have a brush motor.

A moped is a two-wheeled or three-wheeled vehicle with an automatic transmission and a motor having a piston displacement of less than 50 cubic centimeters, that is capable of propelling the vehicle at a maximum speed of not more than 30 miles an hour on level ground, at sea level.

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.
