在欧空局(ESA)商业孵化中心的支持下,荷兰B4自行车(B4-Bikes)公司研制开发出1款新型的电动自行车——B4e-cruizer(电动巡航者)。其采用ESA在航天器太阳能阵列稳定器方面的专利技术,优化了其48V/18A的电池的使用。目前,许多城市都面临着高峰时段的交通拥堵问题。调查发现,在早高峰时段,80%的驾车出行的车程短于20km,80%的车辆仅载有1人。这不仅浪费了时间和燃料,也对驾驶人员的心理造成了压力。正是为了解决这一问题,B4 With the support of ESA Business Incubator, B4-Bikes has developed a new e-bike, the B4e-cruizer. Its patented ESA technology for spacecraft solar array stabilizers optimizes the use of its 48V / 18A batteries. At present, many cities are facing traffic jams during rush hour. The survey found that 80% of car trips are shorter than 20km in rush hour and 80% have only one car in the rush hour. This not only wasted time and fuel but also put pressure on the driver’s mind. It is to solve this problem, B4
