Cambridge Introduced To Ultramotor A2B Electric Bike

Cambridge Introduced To Ultramotor A2B Electric Bike


Cambridge, England — The Ultramotor A2B electric bicycle is a comfortable ride, with a large saddle, wide tyres, shock absorbing front and rear suspension, and Avid BB5 disc brakes. One drawback is the bike weighs 31 kg, and you have to be pedaling before you can start the motor.

The A2B by Ultramotor costs £2,000 price tag. It has the classic shape of a Moulton bicycle with the ability to ride without even having to pedal, with very little noise and no petrol fumes.

The bikes are built in China, distributed by an American company and sold in Britain through The Electric Transport Shops in Oxford, Cambridge and Camden Town.

The motor on the rear hub is powered by a 36v lithium-ion battery, operated by a twist-and-go throttle control on the right handlebar. A conventional seven-speed derailleur gear shift is operated by a twist grip on the left hand. The battery lasts about 20 miles. Rechargeable, it requires a three- to four-hour charge from any domestic electricity supply.

THere’s no law that says riders have to wear a helmet (although it’s a good idea). European laws say riders mst be over 14 years of age, British laws restrict their speed to 15mph. (The A2B can get up to 20mph at the press of the Boost button.)

Norton Electric Motorcycle Built in Kitchen

Norton Electric Motorcycle Built in Kitchen


Highland County, VA – The Norton Electra Project provides motorcyle lovers with a way to conserve resources and looks to develop an electric motorcycle design.

Lawyer and motorcycle enthusiast Brian Richardson has built an electric motorcycle in his kitchen. His idea to build an electric motorcycle came about in September 2008, after he viewed the documentary, “Who Killed the Electric Car?” which follows the 1990s creation and then discontinuation of electric cars in California.

Richardson said the movie angered him and made him want to build an electric motorcycle in his kitchen, “just to show how easy it is.”
With no formal training in engineering, Richardson is learning as he goes. “I’m an attorney,” he said. “Most of this stuff is kind of foreign to me.” The most experience that he can claim is a general interest in tinkering with machinery and skills.

He chose for the motorcycle’s frame, a Norton Featherbed, which was famous for racing during the 1950s and 1960s. The motorcycle itself, which Richardson refers to as a Norton Electra, is named after a 1960s Norton model.

The Britain-based Norton Motorcycle Company, which was shut down in the late 20th century, has recently reopened with new leadership, and Richardson said he has been in communication with the company’s new owner and hopes he will come take a look at the bike later this year.

Richardson used lithium ion batteries from China and a motor that allows for power regeneration.

The motorcycle is not only fast, but silent. Other than the benefits of not using gas, one of the positive features Richardson pointed out is its quiet ride. Gas-powered motorcycles allows one to ride in a natural environment, but the noise generated is a drawback.

New Engine Powers Two Wheelers

New Engine Powers Two Wheelers


There’s a company called KLD, in Austin Texas, that is producing motors for scooters, that are now being produced and used on the roads of Vietnam.

KLD says that their new motor features a substantial shift in electric motor design, one that overcomes motor inefficiencies and EV drawbacks (which other manufacturers try to overcome via battery technologies).

The motor system used by KLD is made from a composite material that generates significantly less heat. And less heat means greater efficiency. They use an innovative nano-crystalline composite material, so that the motor conducts energy ten times more efficiently than traditional iron-core motors, eliminating the need for additional cooling mechanisms. In addition, of course,   it gives greater responsiveness. With its high frequency to low RPM ratio, the KLD motor does not need a transmission. And  it uses standard batteries.

The cost of a scooter with a KLD motor system in the Vietnamese market is $1500 to $2000, or about what a run of the mill EV scooter costs here in the U.S. KLD says that by increasing the production run, the economies of scale should bring the costs even lower for large markets.

KLD is working with Sufat, the leading Vietnamese-based scooter manufacturer, to develop a new line of scooters designed to integrate electric motor system.

Vietnam has over 22 million scooters on the road, which is a huge number of a place the size of New Mexico, so they know scooters!

Electric Bikes Vs Engine Powered Bikes

Electric Bikes Vs Engine Powered Bikes


An electric bike is not the same thing as an electric scooter or motorcycle.

The difference is rather obvious – an electric bike has pedals! This enables the rider to pedal and get some exercise, using the motor only when faced with a long uphill climb, or when just a little bit more speed is wanted for some reason.

An electric bike is a vehicle that is subject to the rules of the road. (So is a standard bicycle, for that matter.) Because we want electric bikes to be accepted, we must know the rules of the road and follow them. Otherwise, tickets and outraged motorists will be left in our wake!

The location where you purchase your electric bike should be able to give you a manual for the rules of the road – or more likely will point you to the website where they are posted. Ignorance of the rules is no excuse when it comes to the police – they will ticket you for breaking them.

Because an electric bike has a bit more power than a regular bike, it’s easier to use it as a shopping transport vehicle. But many people ride them just as they would their normal bikes, just for pleasure, although, again, secure in the knowledge that if they come to a monster hill, they won’t have to kill themselves getting to the top of it.

Indeed, that is the only drawback to an electric bicycle – the weight. A battery pack currently weighs about 17 pounds. Well, think of how strong your legs will get pedaling all that extra weight around.

In addition, an electric bike can be solar powered. Think of how sweet that would be. The solar panels would be in the wheels. The energy absorbed from the sun is transmitted to the battery where it is stored and used on demand. Such a battery would last a long, long time.

Rather than purchase a brand new electric bike, why not start out by purchasing a “conversion kit” to turn your current bike into an electric one. Give it a try for a while, and see if you don’t become hooked.
