    Controlling the acceleration of the motor

    i see. thanks for the explanation. so the rate of change of voltage in the throttle signal is proportional to the current going into the motor, hence acceleration. to clarify. but how does the system know how fast the voltage should change. by how fast u change the throttle position? what if...

    Auto Cruise vs Manual Cruise

    I see most ebikes controller have an auto cruise timing of 6 to 8 seconds commonly.... 6 to 8 seconds seem reasonable. anything too short may lead to unwanted activation of cruise. tilt the throttle a bit and it should make things easier to hold.

    Controlling the acceleration of the motor

    all the throttle i see are potentiometer so it's voltage signal throttle. how does CA3 convert it to current throttle or power throttle? what are the advantages of current throttle over typical potentiometer voltage signal throttle?

    Controlling the acceleration of the motor

    hi, the throttle has a potientiometer and varying the voltage signal of the throttle changes the speed of the motor. so how do you control and vary the acceleration of the motor? can advise? thanks regards brian

    Coolpeds electric kickscooter

    what you pay is what you get. the range for coolped is quite limited. Design is very standard. the tire is too small and thus not stable enough and cannot withstand bumpy roads. china controller has a lot of reliablity issues. Motor power is 200W, quite low.

    what's your idea tire size for scooter?

    The bigger the tire the better for potholes n rougher terrain but it also adds on weight and affect portability. smaller tires being lighter will result in better acceleration. what's your preference tire for a scooter? esp for an urban dweller.
