I have an Altec focus fatbike with a GD01 display, I cannot edit the max speed parameter. I've tried pressing the up/down key on it, and nothing. I can edit other parameter settings though. How can I fix this?

I recently bought an Altec Focus fatbike with a GD01 display, entered parameter settings and everything can be changed but the P8 (max speed) one. How can I fix this?

I mean it was pulling 500 normally, ever since I got it.

The motor issue I was referring to is when I bike normally, after some time at ~20 KPH the motor cuts, makes like a shredding noise, the speed shows at 40-60 and it like stalls. Then after a few seconds or braking completely it restores.

I contacted the manufacturer about the motor issues, they said to bring it so I'll do so on Friday/Saturday.

Any update?

Is there a way to have the motor consistently give 400-500 watts with PAS?

Just added my throttle, doesn't even work??

It gives 500 at the start, keeps going down after. When at ~20 it goes to ~200 with PAS. My throttle is coming today so I'll see how it functions.

Appeciate the detailed reply - It works, as for Imitation Torque Control, no clue.

Kinda worked, reached 28-29, could anyone explain C1 to me?

Alright, I'll check now.

Appreciate the reply, the following are my settings: P1 - 87 P2 - 1 P3 - 1 P4 - 1 P5 - 15 C1 - 07 C2 - 0 C3 - 5 C4 - 1 C5 - 10 C6 - 5 C7 - 0 C8 - 1 C9 - 0 C10 N/A C11 - 0 C12 - 4 C13 - 0 C14 - 2 C15 -6

I honestly think it's the P & C settings, could anyone give me a list of what it should be for a RKS 36V 250W motor?

Yeah, that's what I'm saying. I'll send a picture and call them up today.

I have no clue what controller it is, they (the repair center) scratched off the white lable on it, no clue what specific controller.

As for P and C settings, I configured them correctly. When I checked the controller to find out which one it actually is, they scratched off the white label on it. Very annoying. They also added a weird speed sensor it looks like which messed up my speedometer, showed me going 7 when I was at 20..

Hi Harry, I appreciate the reply! I'm not so good with wiring, I do know where to find the controller, mind if I send a picture of all the wires so you can help me find it?

Fair, it was a quick steal for the price I got it. Appreciate the reply though!

have a RKS RD5 electric fatbike, 250w motor, 36v with a KT-LCD3 display. I recently had some repairs done, before this I could go 36 KM/H, since the repair with the display being changed and more, I cannot. I tried changing paramater settings, the KT-LCD3 max speed is set to 72 yet it limits me...
