阅读下面的短文，请根据文后的要求答题（注意问题后的词数要求）
Michelle and Barney Wanstall rode off into the Lake District sunshine yesterday with no trouble at all.
They were the first customers to try a new electric bicycle hire service aimed at tourists who want the fun of cycling without pain. “We wanted to go on a boat when we first got here,” explained Mr. Wanstall, a student. “But we saw these bikes and decided to hire them instead.”
Brian Eaton, owner of Easyriders, which has a dozen bicycles for hire by the side of the lake near Coniston village, smiled as Michelle looked anxiously at Coniston Old Man, the mountain that towers over the village.
“We do quite a lot of cycling at home,” said Michelle. “But with mountains everywhere, it’ll be easier if we _______________________. And it’s only £18 each for a day’s easy riding and the chance to enjoy some of the finest co
untryside in Britain!”
The motorized bicycles helped the couple as soon as they began to pedal; they would have needed to use twice as much energy with a normal bicycle. The bicycles are very safe; they cannot go faster than 15 mph and t
he special tyres cannot be punctured. “It’s easy riding,” said Mr. Eaton. “There are a lot of people fancy cycling, but are not as fit as they used to be!”
Riders are provided with helmets, maps, routes and suggestions for picnics and places to stay. Most electric bicycles are sold in Japan. However, Mr. Eaton thought they would be popular with tourists in the Lake District. “As far as I know, these are the only motorized bicycles for hire in the country,” he said. “If the idea is successful, I’ll set up other hire centres around Britain.”
