Now Minneapolis-based inventor Rich Kronfield has created an electric-assist 'Raht Racer' velomobile that he claims can travel at up to 100mph (160km/h).

现在美国明尼阿波利斯的发明家里奇•科伦菲尔德研制了电动“拉特赛车”（Raht Racer）人力躺车，声称其速度每小时能高达100英里（即每小时160公里）。

'The Raht Racer is a power biking vehicle that uses state of the art pedal-electric hybrid¹ technology to amplify² pedal power, enabling the rider's legs to propel the vehicle up to highway speeds, giving the rider the feeling of super strength,' Mr Kronfield says.

“拉特赛车是一种动力自行车，使用脚踏电动混合技术来增强脚踏的动力，使得骑行者的腿能够推动自行车达到高速公路的速度，让骑车人感受到超强力量，”科伦菲尔德如是说道。

'On a bicycle, your pedals are the accelerator. Same with the Raht Racer, only multiplied a hundred times.'

“在自行车上，踏板是加速器，拉特赛车也一样，只不过拉特赛车的速度是它的百倍。”

The Raht Racer's pedals are connected to a unique flywheel generator³ rather than of directly driving the wheels, as in a traditional velomobile.

拉特赛车的脚踏板与独一无二的飞轮发电机连接，而不是像传统的自行车一样直接与车轮连接。

The pedals power a 20-kWh electric motor, which sits in the rear wheel hub.

拉特赛车的脚踏板为处于后轮毂的20千瓦时的电动机提供动力。

The vehicle senses the torque being applied⁴ to the pedals, and then amplifies⁵ it so that most people can maintain a cruising speed of around 30 mph (48 km/h).

这种装置能检测到脚踏板上的扭矩，大幅提高了它的作用，所以大多数人能维持在每小时30英里（即每小时48公里）左右的行驶速度。

The body of the two-seater Raht Racer is made from carbon fiber⁶ and includes a roll cage, headlights, seat lights, air bags and a trunk.

两人座的拉特赛车主体由碳素纤维制成，包括一个防滚架，车头灯、座位灯、气囊和一个后备箱。

During pedalling, a 2-kWh li-ion battery pack also gets charged to help extend the 570lb (259kg) velomobiles range.

踩踏过程还能为一个2千瓦时的锂离子电池组充电，延长总重量570磅（即259公斤）的躺车在道路上行驶的时间。

When activated⁷ in throttle⁸ mode, using just battery power, it has a range of approximately 50 miles (80 km) and a top speed of 100 mph (160 km/h).

启动发动机油门控制模式时，也就是完全使用电池电源动力时，拉特赛车能跑50英里（即80公里），速度最高可达每小时100英里（即160公里）。

Mr Kronfield has created a prototype and is currently running a Kickstarter campaign to create a commercial mode.

科伦菲尔德创造出了一个模型，目前正在美国Kickstarter众筹网上开展筹款活动来创造一个商业模式。

According to the Kickstarter campaign: 'The system provides variable resistance, based on programmable or pre-set workout profiles, and GPS terrain-sensing virtual hills, all with torque amplified⁹ pedalling'.

据众筹网上的信息显示：该系统提供可变电阻，以可编程的或预设的训练资料和GPS地形遥感虚拟山为基础，这些都与扭矩增强踏板的功能有关。

It is estimated the price of the Raht Racer will start at $35,000 (£22,800) if the campaign is successful.

如果这个项目成功的话，拉特赛车的价格预计约为3.5万美金（约合2.28万英镑）。
