The batteries are the most important parts of the bike, because (if you don’t do any pedaling) they contain all the power that will drive you along. Typical electric bike batteries make about 350–500 W of power (that’s about 35–50 volts and 10 amps), which is about a quarter as much as you need to drive an electric toaster. In theory, you could use any kind of battery on a bicycle. In practice, however, you want to use something that stores lots of power without being too heavy—or you’ll be using half your power just moving the battery along! That tends to rule out heavy lead-acid batteries like the ones that start cars, though some electric bikes do use them. Lightweight lithium-ion batteries, similar to those used in laptop computers, mobile (cellular) phones, and MP3 players, are now the most popular choice, though they’re more expensive than older rechargeable battery technologies such as nickel-cadmium (“nicad”). Typical batteries will give your bicycle a range of 10–40 miles between charges (depending on the terrain) and a top speed of 10–20 mph (which is about the maximum most countries allow for these vehicles by law). You can extend the range by pedaling or free-wheeling some of the time.
Yet if electric bikes end up replacing human-powered bikes, or if they are used only for exercise or fun, they could well add to pollution because they consume electricity, much of which comes from burning fossil fuels. Only if electric bicycles replace cars will their environmental benefits materialize — and that’s the goal, say bike makers.
E-bikes can be a useful part of cardiac rehabilitation programmes, since health professionals will often recommend a stationary bike be used in the early stages of these. Exercise-based cardiac rehabilitation programmes can reduce deaths in people with coronary heart disease by around 27%; and a patient may feel safer progressing from stationary bikes to e-bikes. They require less cardiac exertion for those who have experienced heart problems.
This is truly the most fashionable of the e-bikes we’ve assembled. For a hipster-stylized, commuter workhorse, the Faraday Porteur is hard to beat. It’s fairly inexpensive—for an e-bike—at $3,499, looks sleek and streamlined, and rides smoothly. Perhaps best of all, it doesn’t look like a traditional e-bike: Instead, it appears to be a singlespeed, although it features an internal eight-speed hub and a Gates belt drive for stealthy shifting. It’s an excellent commuter bike because it’s easy enough to pedal without the e-assist, but with it, you’ll zoom along without breaking a sweat. As a bonus, you can order this bike from the comfort of your own home on Faraday’s site, where you can customize the color and select accessories. If price is an issue, check out some of the more budget-friendly options like the Porteur S, which starts at $2,800.

“[the] electric motor must have a power output of no more than one thousand watts, be incapable of propelling the device at a speed of more than twenty miles per hour on level ground, and be incapable of further increasing the speed of the device when human power alone is used to propel the device beyond twenty miles per hour.”

You should never make a “high speed pass” period. If the person you are passing steps in front of you, or serves becuase they don’t know you are there, and you can’t stop and prevent an accident, you have failed to do your job as a responsible citizen. When you pass a person, or another bike on a trail, slow down to near their speed before you pass them — don’t just go zipping past them at 25 mph because you can. That’s exactly the type of behavior that will get eBikes outlawed from bike trails. You are not doing any of us a service by making “high speed passes”.
We believe that only our riders should control the power and speed of our Electric Bicycles, so all of our bikes are throttle controlled. We believe that controlling the speed and brakes on a bicycle are intuitively linked as an extension of the hand.
A lightweight, high speed, electric road bike with sturdy 12 mm thru-axle on the front wheel, Carbon fiber fork, and Alpha 200 Gold alloy frame to dampen vibration. Capable and comfortable on hard packed trails as a gravel grinder, sturdy Aluminum fenders and……
Baby boomers are an obvious market for electric bicycles. “We’re seeing an aging population, and a growing number of people getting back into cycling,” says Bill Moore, an Internet publisher who recently launched ePEDALER, an electric-assist bicycle retailer. Urbanization will be another driver of electric bike sales, Moore said, as will the obesity crisis, rising health care costs, and the desires of employers to encourage their workers to become more active.

Maybe you merely have to pedal without the motor to be legal on that trail. Or maybe you just have to ride slow. Maybe if you look just like a gasoline scooter, nice little old ladies start throwing rocks at you. It can be quite peculiar at the local level. One day, I nearly got in a fist fight with 30 jogging body-builders that decided my e-bike was not allowed on the trail. They thought ALL bikes were not allowed. Some days you just have to bend to the local peculiarity of that day. That day, I got off the path, and got back on again once I was out of their sight.
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.

Photo: Could solar power be the future of electric bicycles? The large solar panel mounted over the back wheel of this experimental bike powers an electric motor connected by a chain drive to the back wheel, helping the rider when he doesn’t feel like pedaling. Using clean, green solar power would remove the problem of having to charge electric bikes with electricity generated from fossil fuels—and help to extend their range significantly.

S-Pedelecs: have pedal-assist only, motor power can be greater than 250 watts, can attain a higher speed (e.g., 45 km/h) before motor stops assisting, legally classed as a moped or motorcycle (not a bicycle)
Don’t drive like a maniac. Don’t use it if it looks too motorized and not like a regular bicycle. Don’t be underage. If you are in your 50’s and want to ride park paths where other bicycles are, you should be fine. If you are a young kid trying to make a living delivering food in NYC, riding as fast as your can, you might raise an eyebrow.
Yes, we offer a 24-month warranty on the battery, and an 18-month/1,800 mile warranty on the parts and frame for the 100 series e-Bikes. For the 200 series, we offer a 2 year warranty on the frame, drivetrain and battery.

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.
The article clearly states New York CITY – there is NO IMPLICATION regarding New York State… Albany is NOT in THIS PARTICULAR equation. Did you even bother clicking on the link to “New York City made a CITY-wide ban on e-bikes”?
To ride an ebike, a user pedals or triggers the throttle for the electric motor, providing power to the wheels. Some ebikes can go as fast as 28 mph. The speed is dependent on how hard someone pedals or pulls the throttle.
Electric Hybrid Bikes- As the name suggests, these bikes combine the properties of mountain and fat-tire bikes. They are built to be fast and, at the same time, tough. They are lighter than electric mountain bikes, so you don’t have to deal with the excess weight when going up hills. You can use the bike to carry heavy luggage or cycle through rough trails.

The last e-bike component we’re going to discuss is the throttle. A few e-bikes use levers much like you’d find on lawn mowers. Some just have a button, but most use motorcycle-style twist grips. These give a positive feel and more precise control.
