Except this ,battery also should be noted , for ensure enough popwer and longger mileage ,the battery at least to be 72v20ah


Also electric motor should be attention , because the electric motor is the heart of the vehicle , one stable electric motor could ensure vehicle long terms use , electric motor power should be more than 500w , besides , good quality motor has very small noise , with strongger capacity of shock-proof ,which will not transform during long terms use , its loading capacity also will be stronger .


Electric controller is one of first importants parts for e-vehicle too , electric controller will control e-vehicle start ,runing ,frward/backward ,break and others fuction , vehicle speed is control by electric controller ,which control the motors running speed by controlling output electricity .


Finally , we also should pay attention to vehicle’s mileage , which useually by battery capacity . battery’s cpacity= battery’s voltage (v) * battery’s electricity (ah) . vehile running time = battery capacity /electric motors power .
