Electric bicycles how to inrease speed

I bought electric bike on visit in China and I had brought it with me on the plain back. After I brought the electric bicycle home to New Zealand I took it a part to see the secret how it is made. When I open the box where is on electric bike hidden a regulator there i found  a little potentiometer. By turning the potentiometer around and watching what is happening I found that it is for regulating the speed. Most of the regulators for electric bikes are design to speed 25km/h(european standart)  and has an output where by adding a trimpot can be the speed reduced down. It is adding flexibility in use. Chines regulations limiting the speed on 20km/h .If you imported electric bicycle from china or you bicycle goes less than 25km/h you can have a look in regulator if is not possible adjust the trimpot to 25km/h speed.
