CSC 1500W wheel - Is it possible to increase the speed ?

[Nino1967]

Hello guys,

I just finished building the ebike.

There is a rear wheel motor CSC 1500W.
The controller is a 48V - 35A.
The battery is a 48V, 20A.

The SW900 LCD is set to these parameters.

At the moment, the maximum speed is 35 km/h.

Does anyone know how to increase the speed by having different settings, or a different controller or something else?

Thank you very much.

Nice looking bike! I don’t know much about the SW900 screen. Unless the controller is capping your top speed through software, getting more speed takes a lot of work. You’d need to add more volts to the system, which means replacing your battery and often means replacing the controller, and sometimes means replacing all the bits and bobs like screen, throttle, PAS sensor, etc., if those aren’t rated for the higher voltage.

I hope someone else comes along and can inform you about a adjusting the max speed trough the SW900, but if your wheel’s already spinning as fast as the motor will turn at this voltage, hardware is the solution.

Switching to a 52V battery should get you 7% more speed.

Depends on what is limiting the speed, and what your specific riding conditions are.

Does the wheel spin noticeably faster at full throttle when it is off the ground than when you are riding? If so, then it is not limited by the controller as a speed limiter, so there are various things you can do to increase speed without replacing the controller, depending on your conditions.


Assumign the above, are you riding only on flat roads, no significant winds? If so, increasing system voltage as noted by E-HP to a 52v battery (14s) instead of a 48v battery (13s) will increase top speed a small amount.

If you have uphills or slopes or winds, it may require more power (generally from battery / controller current), and that might require changing your controller (and battery).


Also note that if your battery really is only a 20A (not 20Ah--very different thing) battery, then it probably can't provide the current the controller needs to do it's job at higher loads without a lot of voltage sag, which takes away speed. In that event, a better battery that can handle more than the load required of it would help with this problem, and may (depending on conditions) give you a little more speed.


Since it's a somewhat complicated relationship between conditions and parts on the system, you can experiment with the http://ebikes.ca/simulator to see these, and then simulate your actual conditions and something like your system, to see what you have to change to get the results you want.

Does the controller have a wire labelled 3 speed switch? You might need to connect them
