In the theoretical electric bike we considered up above, we had the dynamo/motor driving the back wheel directly, simply by pressing on the tire. Most electric bikes work a different way. They have compact electric motors built into the hub of the back or front wheel (or mounted in the center of the bike and connected to the pedal sprocket). Take a look at the hub of an electric bike and probably you’ll see it’s much fatter and bulkier than on a normal bike. You can read more about how these motors work in our main article about hub motors.

The best Electra Townie Go! design I’ve tested to date, better weight distribution, increased efficiency and greater power thanks to the Bosch Performance Cruise drive system. Available in six different colors with matching aluminum fenders, chain guard, rims and carry rack,……

Brakes: Caliper brakes (the type found on ordinary bicycles) are common on e-bikes, but disk brakes offer better stopping power. In wet conditions, however, initial braking can be slowed as you first clear water from the disk. It’s a minor thing, and you soon get used to it.

  Now I will dig through some examples of state motor vehicle codes, to give an example of how to find and possibly understand  the statutes, short of hiring a lawyer. In the examples, I give only my personal opinion of what the statutes mean.

Today, China is the world’s leading producer of e-bikes. According to the data of the China Bicycle Association, a government-chartered industry group, in 2004 China’s manufacturers sold 7.5 million e-bikes nationwide, which was almost twice the year 2003 sales;[11] domestic sales reached 10 million in 2005, and 16 to 18 million in 2006.[10]

E-bikes are classed according to the power that their electric motor can deliver and the control system, i.e., when and how the power from the motor is applied. Also the classification of e-bikes is complicated as much of the definition is due to legal reasons of what constitutes a bicycle and what constitutes a moped or motorcycle. As such, the classification of these e-bikes varies greatly across countries and local jurisdictions.

We easily rode 30 e-bikes or more this year. Almost all of them impressed us one way or another. Some are expensive and others more affordable. As with most expensive e-bikes, you pay for the difference in quality and feel. But not all entry-level e-bikes have to feel like a cheesy attempt to convert a heavy regular bike with a battery pack and an electric motor.

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.

If you’re going for a full-time electric bike, the distance you travel on a single charge will be reduced considerably, though it’s difficult to offer precise figures. Manufacturers will quote anywhere from 20 to 40 miles while simultaneously using phrases like “in ideal conditions.”

High pedal assist = you feel like superman!  High pedal assist is when you want to get somewhere quickly and with minimal effort.  This could be useful if you want to get to work without sweating too much.  On the way home you could use the low pedal assist to workout the stress of the day.

By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle.[7] Schnepf’s invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.[8]

“You honestly feel like you’re floating,” said Marino, who found pedaling easy for his recovering leg. “I felt like I was riding horses again. Instead of trails, I was road biking in and out of traffic.”

We chose this trip for the wonderful locale AND the e-bikes. They were liberating. You still have to pedal, but the bike gives you an extra boost to get up the rolling hills. This leveled the playing field for us, so we could keep up with younger, more experienced cyclists and get our full share of joy in biking the wine country. The e-bikes — and our outstanding guides — enabled us to take a full measure of pride in cycling more than 160 miles in 6 days, our biggest trip ever.

The industry is benefiting from improved batteries as suppliers over the years developed technology for laptops, smartphones and electric cars. In 2004, lithium ion battery prices fell low enough to be used on electric bikes, spurring European sales, according to Edward Benjamin, senior managing director at eCycleElectric Consulting.

Visually, the Pedego City Commuter Classic Electric Bike is stunning – a smart blend of yesteryear’s style and today’s technology. Pleasantly high handlebars, a sprung seat, and lovely Schwalbe Fat Frank tires make it very comfortable. Stopping is taken care of by powerful disk brakes, front and rear. Lights are included, as is a useful cargo rack. From an e-bike standpoint, the Pedego Classic City Commuter sports a reliable, hub-mounted motor driven by a 36-volt, 10-amp battery. There’s a digital display with a trip computer, odometer, speedometer, pedal assist level, and battery charge information.

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.

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.
