The number of super-fast electric bikes in the Netherlands has soared 60% in the past two years to 17,200, according to new figures from national statistics agency CBS. The bikes, which can travel at up to 45 kph, are particularly popular with the over-55s and the province of Utrecht has the highest density in the country. There are also far more electric mopeds on the roads – up 74% to 6,000 in the two years to July 1, the CBS said. At the same time, the number of registered traditional mopeds has gone down 2.8% or nearly 15,500. The number of cyclists killed on the Dutch roads outstripped the number of people killed in cars for the first time in 2017, according to figures from the national statistics office CBS last year. The over-65s account for two-thirds of deaths among cyclists, and e-bikes were involved in one in four bike accidents.
