Carrera Crosscity ebike

[cem1965]

Hi, can anyone tell me if it is possible to upgarde my carrera crosscity ebike, meaning putting on a throttle and a bigger controller and battery so i don't have to be limited to the slow stock 15.5mph speed limit. It uses Halfords own controller which is very tiny like about 3'' by 2'' in size and dosn't give much humph for your money. Thanks for any advice.
