There is an article about the e-bikes in Europe which provides assistance to the biker. Unlike an ordinary electric bike with a motor that you can ride without pedaling, this new e-bike just makes it more convenient for the biker to lighten up the pedals. The objective is to motivate the biker to use the pedal although the motor can still bring the rider home but only in a slow pace. It is recommended for seniors who are fond of physical exercise but don't have the energy to use a regular bike.
