用智能手机把单车人工换档改造成自动变速

Forget bicycles with gears that you have to change yourself: the first wireless automatic gearbox for a bike does it all for you.

不必再用人工方式给单车换档:现在为您推出首款单车无线自动变速换档系统。

The system, unveiled today, uses your smartphone to calculate the best gear to be in for the current pedalling speed – then wirelessly shifts up or down.

今天介绍的变速换档系统是用智能手机选择最佳换档齿轮位置,然后实行无线变速。

It also uses the phone’s accelerometer to know when to change down in an emergency stop – so you can pull away afterwards with ease, and will eventually be able to use the phone’s GPS capability to get the bike into the correct gear for an upcoming incline.

也可用手机加速计得知需紧急制动要减速的时候 –以便从容骑行 ; 在进入上下坡路面时,还能用手机GPS功能为单车选择正确合理档次。

Mechanical automatic gear boxes for bikes already exist – but they wear out quickly as they’re based on moving flywheels. The new wireless method activates an electric gearshift that has no such issues – and thanks to its use of a smartphone can also analyse performance for serious cyclists.

单车机械式自动变速装置已使用多年,零件相互运动使其迅速磨损。智能手机可分析骑车人骑行状况,能用无线控制方法驱动电子换档装置。
