Can the US Electric Bike Market Get a Jump Start? | Electric bikes are different from motorcycles or mopeds, which rely on motorized power; they are bicycles that can be pedaled with – or without – help from an electric motor. Riding an e-bike feels like riding a normal bike with a strong wind behind you; the motor just helps you go faster or climb hills. Unlike mopeds, e-bicycles are usually permitted on bike paths and they can’t travel faster than 20mph. | 1Int
| What is one difference between e-bikes and mopeds with regard to their motors? | 2 | [
"E-bikes can be ridden without using their motor",
"E-bike motors are less resilient to wind",
"E-bike motors are better suited for going fast uphill",
"E-bike motors are quieter"

Can the US Electric Bike Market Get a Jump Start? | To succeed, the electric bike business in the US must clear legal, cultural and financial hurdles. E-bikes are banned in some states, including New York, although the law isn’t strictly enforced. Traditionalists who own and staff bike shops don’t like putting motors on bicycles, citing, among other things, the added weight. Some e-bikes are close to 30kg. E-bikes are also pricey. While low-end models sell for as little as $700, Court Rye, the founder and editor of ElectricBikeReview.com, a popular website, says riders should expect to pay at least $1,500 for a quality e-bike with a good battery. Top-of-the-line models cost more than twice that. | 0Adv
| Why don’t some bike sellers want to put motors on bikes? | 3 | [
"Because they prefer the bikes to be lighter",
"Because the bikes they sell already have a weight of almost 30kg",
"Because motor sales are banned in some states",
"Because they think e-bikes are unsafe"

Can the US Electric Bike Market Get a Jump Start? | The companies that make and sell e-bikes say they can overcome those obstacles. E-bike technology, particularly the batteries, is improving. “Batteries are getting smaller, they’re getting lighter, they’re getting more reliable and they are lasting longer,” says Don DiCostanza, the founder and CEO of Pedego, an electric bikemaker and retailer. Big companies like Bosch and Shimano are entering the business, which should help erode resistance from bike shops. In the meantime, lobbying efforts are underway to permit the use of e-bikes everywhere. Perhaps most importantly, as more cities build cycling infrastructure, including dedicated bike lanes, bicycle commuting has become more popular. As the US Census Bureau reported in 2014, the number of bike commuters grew from about 488,000 in 2000 to 786,000 in 2012. Electric bikes make commuting more practical – and fun – by easing worry about hills, headwinds and fatigue. | 0Adv
| What does DiCostanza say about e-bike batteries? | 4 | [
"They used to last for a shorter time",
"They used to be smaller",
"Their sales increased between 2000 and 2012",
"They will soon be rechargeable at gas stations"

Can the US Electric Bike Market Get a Jump Start? | Most of our customers are “aging baby boomers who want to rekindle the experience they had as a kid,” says Pedego’s Don DiCostanza. “The main reason they stopped riding bikes was because of hills.” Pedego has opened nearly 60 stores in the US and it has sold bikes to tour companies in San Francisco and Washington, DC. ElectroBike, which operates 30 stores in Mexico, opened its first American store in Venice Beach, California in the autumn of 2014 and hopes to grow to 25 US stores in a year. CEO Craig Anderson says: “We want to help reduce traffic, help reduce our carbon footprint and promote a healthy lifestyle.” Startups like Pedego and ElectroBike will have to compete with big companies like Trek and Currie, which, in 2012, was acquired by Accell, a public company based in the Netherlands that is Europe’s market leader in e-bikes. Accell owns the Raleigh brand, as well as Haibike, an award-winning German electric bike. | 0Adv

Can the US Electric Bike Market Get a Jump Start? | Most of our customers are “aging baby boomers who want to have the cycling experience they had as a kid,” says Pedego’s Don DiCostanza. “The main reason they stopped riding bikes was because of hills.” Pedego has opened nearly 60 stores in the US and it has sold bikes to tour companies in San Francisco and Washington, DC. ElectroBike, which operates 30 stores in Mexico, opened its first American store in Venice Beach, California in the autumn of 2014 and hopes to grow to 25 US stores in a year. CEO Craig Anderson says: “We want to help reduce traffic, help reduce our carbon footprint and encourage a healthy lifestyle.” Startups like Pedego and ElectroBike will have to compete with big companies like Trek and Currie, which, in 2012, was acquired by Accell, a public company based in the Netherlands that is Europe’s market leader in e-bikes. Accell owns the Raleigh brand, as well as Haibike, an award-winning German electric bike. | 1Int

The body awarded credit for the discovery of element 113, which had also been claimed by the Russians and Americans, to a team of scientists from the RIKEN Institute in Japan. The decision means Japan becomes the first Asian country to name an element.

Four New Elements Find a Place on Periodic Table | IUPAC announced that a Russian-American team of scientists at the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California had produced sufficient evidence to claim the discovery of elements 115, 117 and 118. The body awarded credit for the discovery of element 113, which had also been claimed by the Russians and Americans, to a team of scientists from the RIKEN Institute in Japan. The decision means Japan becomes the first Asian country to name an element. Under IUPAC rules, new elements can be named after mythological concepts, minerals, a place or country, or a scientist. | 0Adv

When IUPAC has received the researchers’ suggestions, they will tell the public so that people can comment on the names. That allows scientists and others to find any problems with the names. In 1996, someone suggested the symbol Cp for copernicium, or element 112, but it was changed to Cn, when scientists complained that Cp was already the symbol for another substance. | 2Ele
| Why was the suggestion to use symbol Cp for copernicium not accepted? | 5 | [
"The symbol was already being used for a different substance",
"The symbol Cn was already assigned to it",
"UIPAC did not receive the suggestion in time",
"The symbol Co was already assigned to it"

Four New Elements Find a Place on Periodic Table | Scientists must find new names for the elements but, also, they must suggest two-letter symbols for the elements. When IUPAC has received the researchers’ suggestions, they will tell the public so that people can comment on the names. That allows scientists and others to find any problems with the names. In 1996, someone suggested the symbol Cp for copernicium, or element 112, but it was changed to Cn, when scientists complained that Cp was already the symbol for another substance. | 2Ele
| Why is the public involved in the element symbol-naming process? | 5 | [
"To see if there are issues with or opposition to a proposed symbol",
"To source suggestions for symbol names",
"To avoid complaints about overinvolvement of scientists",
"To get the public more excited about scientific discovery"

Four New Elements Find a Place on Periodic Table | To discover the elements, researchers at the three labs slammed lighter nuclei into one another and looked for signature radioactive decays that should come from the new elements. Ununtrium and ununpentium are thought to be metals, while ununseptium could be a metalloid – a material bearing some metallic properties. The fourth element, ununoctium, may be a noble gas, like other group-18 elements, helium, neon and argon. It is hard to know for sure because so few atoms of each element have ever been made. Paul Karol, chair of the IUPAC panel that verified the elements, said: “Practical applications of the new elements, if any, are a long way off because of the difficulty in synthesis.” | 0Adv
| How did researchers discover the elements? | 6 | [
"By creating collisions between less heavy nuclei",
"By inducing radioactive decay of other elements",
"By transforming metalloid elements into gasses",
"By removing protons from previously discovered elements"

| What does Paul Karol say about the new elements? | 6 | [
"They will not be utilized for a while",
"They will be used in practice before too long",
"They do not have radioactive decays",
"They reflect huge progress in the chemistry fiel"
