Popularity of electric bikes on the rise.

What’s the world’s best selling electric vehicle?

Trick question. It’s a two-wheeled vehicle, the electric bike. In 2012, 30 million units were sold. However, 92 percent of the world’s e-bike sales come from China. What’s the future of the e-bike in the rest of the world?

According to a new report from Pike Research, the market for electric bikes will increase in the coming years even in places where sales have been minimal. This year in the United States, for example, only about 89,000 e-bikes will be sold. But in the next six years sales are expected to triple, increasing to 265,000 in 2018. Worldwide, sales will reach 47 million by 2018, bringing in $12 billion that year.

“Although the e-bicycle will remain a niche product in the United States, the U.S. market is expected to expand at a compound annual growth rate of 20 percent,” said Pike’s senior research analyst, Dave Hurst, in a statement. “That means it will continue to trail significant Western European markets, but increases in bicycle infrastructure in growing urban centers and the rise in popularity of alternative means of transport will make e-bikes a viable choice for thousands of new users.”

In the report, one of the major challenges cited for e-bike growth is distribution. Typically, the people who buy e-bikes are not the same customers as traditional bike buyers, so bicycle dealers are hesitant to carry the product.

The costs for the e-bike are definitely higher and they require more maintenance with an electric battery to charge. But it’s no surprise that the vehicle is starting to slowly catch on in the U.S. It’s a vehicle that can get you around the city quickly and is a cheaper alternative to a car.

Heartbeat ‘could power pacemaker.


A device which could harness energy from a beating heart can produce enough electricity to keep a pacemaker running, according to US researchers.

Repeated operations are currently needed to replace batteries in pacemakers.

Tests suggested the device could produce 10 times the amount of energy needed.

The British Heart Foundation said clinical trials were needed to show it would be safe for patients.

Piezoelectric materials generate an electric charge when their shape is changed. They are used in some microphones to convert vibrations into an electrical signal.

Researchers at the University of Michigan are trying to use the movement of the heart as a source of electricity.

In tests designed to simulate a range of heartbeats, enough electricity was generated to power a pacemaker. The designers now want to test the device on a real heart and build it into a commercial pacemaker.

Dr Amin Karami told a meeting of the American Heart Association that pacemaker batteries needed to be replaced approximately every seven years.

“Many of the patients are children who live with pacemakers for many years. You can imagine how many operations they are spared if this new technology is implemented.”

Prof Peter Weissberg, the medical director at the British Heart Foundation, said: “Advancing technology over recent years has meant people with pacemakers need to change their battery less often. This device could be another step forward along this path.

“If researchers can refine the technology and it proves robust in clinical trials, it would further reduce the need for battery changes.”
