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.

Electric bikes are a green alternative to driving a vehicle. Studies carried out in several towns and cities show that the average car speed in rush hour traffic can dip as low as 18 to 20 mph. Electric bike speed can be as high as 15 mph. With an electric bike, you can reduce pollution, improve fitness, and still arrive at the same time as your car-bound colleagues.

Think I care if I push laws boundries? Nope, I will suffer the consequences if they catch me having fun. The law can’t keep up with the times, we can build bikes faster than they can ‘debate’. As soon as I found E-biking, I drive car 1/4 so Gassing every week to a month of what I used too. And I realized cars are not fun to work on, when you have a two wheeled beauty to tinker with.

E-bicycle makers eagerly market themselves as “green.” Dashboards on e-bicycles sold under the Polaris brand and made by a Miami-based company called EVantage include a “carbon footprint savings” function to calculate how many pounds of CO2 are saved by using the bicycle in place of a gasoline-powered car. Evelo, a Boston-based startup, recently launched a 30-day electric bike challenge, asking people to give up their car keys and blog about using their electric bikes. “We don’t want to wean people from bicycles,” says Boris Mordkovich, Evelo’s founder, who previously worked at car-sharing company RelayRides. “We want to wean people from cars.”

“Yamaha is a well-known and respected brand, but the market is already pretty saturated with manufacturers,” Flagg said. “This is a very competitive space. The opportunity for a manufacturer to have a huge impact has probably passed.”

I have cerebral palsy and have used a powerchair since I was three…. About a year and a half ago I applied for a grant from the Challenged Athlete Foundation for a handcycle. While I was waiting for letters to go out I worked out at the gym. I was talking to my trainer about handcycles. I explained that because all of the weight was behind the drive wheel in…

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.

Like electric cars, electric bikes are pricey. A basic e-bike can be had for as little as $499 on Amazon, but sturdy, well-designed models with better-quality batteries cost between $2,000 and $3,500. (Conventional bikes sell for an average of about $450 in speciality stores and about $100 in retailers like Walmart and Target where most bikes are sold.) Prices could come down as batteries and electric motors become more efficient, and economies of scale come into play. “The technology is getting better, rapidly,” says Dave Hurst of Navigant.

There’s wisdom in the article though. If you look like a bicycle rider on a bicycle doing bicycle type things, you’ll be treated like a bicyclist. So if it’s legal for bicycles nobody in the law will care. Frat boys in SUVs will still throw beer cans at you. Joggers and horse riders will still swear at you. Everybody will hate you if you’re stupid, but at least you won’t get a ticket.

As the weather begins to drop and the snow starts to fall, it is increasingly important to know how to properly care for your electric bike and its Lithium-ion battery. It may be possible for some people to ride their bikes during the winter months, while others must pack them away until the warmer weather returns. Whether you plan to ride in the cold and snow or if you decide to…

While some companies are emphasizing the practical benefits of electric bikes — they’re good for your health, good for the planet and a low-cost way to get from here to there — others focus on fun and style. They are targeting urban buyers in their 20s and 30s, without a lot of money to spend, for whom the allure of owning a car has diminished.

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 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.

Luckily regardless of the laws, I dont hear much about them being enforced anywhere. For example ebikes are completely illiegal in NYC and people still ride them there all the time, and in fact the city has probably the most successful ebike store in the country: nycewheels

The environmental credentials of e-bikes, and electric / human powered hybrids generally, have led some municipal authorities to use them, such as Little Rock, Arkansas with their Wavecrest electric power-assisted bicycles or Cloverdale, California police with Zap e-bikes. China’s e-bike manufacturers, such as Xinri, are now partnering with universities in a bid to improve their technology in line with international environmental standards, backed by the Chinese government who is keen to improve the export potential of the Chinese manufactured e-bikes.[64]

China’s experience, as the leading e-bike world market, has raised concerns about road traffic safety and several cities have considered banning them from bicycle lanes.[2] As the number of e-bikes increased and more powerful motors are used, capable of reaching up to 30 miles per hour (48 km/h), the number of traffic accidents have risen significantly in China. E-bike riders are more likely than a car driver to be killed or injured in a collision, and because e-bikers use conventional bicycle lanes they mix with slower-moving bicycles and pedestrians, increasing the risk of traffic collisions.[2]

With clear rules on how and where to ride an e-bike, everyone stands to benefit. Local bicycle shops and manufacturers will see increased business and their customers will no longer be confused; people who already ride e-bikes can more easily understand where to ride; and new bicyclists who may be discouraged from riding a traditional bicycle due to limited physical fitness, age, disability or convenience will have new transportation alternatives.

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 some lawn mowers. Some just have a button, but most use motorcycle-style twist grips. These give a positive feel and more precise control.

48V 1000W and 750W super power brushless gearless hub motor. Allow you to swap two power modes between the full 1000W power or 750W power by a single blue switch wire is embedded in controller. 1x 48V 1000W Motor.

Despite these legal complications, the classification of e-bikes is mainly decided by whether the e-bike’s motor assists the rider using a pedal-assist system or by a power-on-demand one. Definitions of these are as follows:

In 2012, two e-bike advocates completed the first 4,000-mile (6,400 km) transcontinental e-bike tour from New York to San Francisco to advocate for e-bikes in major cities across the U.S.[78] Pedego Electric Bikes is the best selling brand in the U.S. Many e-bikes in the United States are standard bicycles converted using a kit. In general, the kits include the motor (the majority of which are hub motors built into the front or rear wheel), a speed controller, throttle (usually twist-grip or thumb throttle), necessary wiring and connectors, and a battery. Several U.S. companies offer conversion kits which also offer advanced lithium battery packs. Major manufacturers also offer complete e-bikes. Trek offers a line of e-bikes using the Bionx system in which the rider programs the controller to determine how much effort the motor will give in response to rider effort, from 25% up to 200% of the rider’s power. This system ensures a minimum level of rider participation and is also used to comply with many European laws mandating partial human effort before the motor engages.

We are regular riders and chose to ride e-bikes and felt it was the best decision we could have made. Because of the size of the group there were extra e-bikes available and three others in the group switched after day one. The e-bike made the uphills no more challenging than our rides back in New England. The long switchback filled downhills were a total delight as the BionX system allows you to shift into negative power and like a car in first gear, holds you back with minimal braking. We got to sit back and enjoy the view!
