Btw I’ve just tried throttle on the connector green red and black you mentioned. The socket didn’t match so I cut it out and stick the cables to respective colours in the bike. It works!

Yes. It is throttle I haven’t checked the voltage but you are right. i have just been to a bike shop. They showed me this in the picture. Guess what cables are the same colour as the one in the motorcontroller. I think socket is also the same type. They advised me to forget about throttle as it is subject to 500$ flne. So for now I’d just enjoy what it is.

that seems throttle or PAS sensor that are 3 cables. PAS (pedal assist sensor) has got to be connected as that how it runs. The other must be it. But if I short circuited in that would blow the motor connector. let me check it out with voltmeter. another question.. lets assume that is that I put an on/off switch there or would be better to have a variable switch? What do you think?

Do you think that cable? Have you tried? I haven’t got multimeter here. Hard to tell the voltage.

Today I had a closer look to motor controller. There are couple of cables are dangling and the rest are connected to cables for motor and the LcD screen. My guess for finding a trottle cable is to search and try ones within the cable for motor.

Battery

Here is the MC.

Btw p2 settings should be 1.40 instead of 156 that gives accurate readings in speed.

The battery size is pretty unusual compared to what is available in AliEXpress

The battery size is pretty unusual compared to what is available in AliEXpress.. do you have a chance to look in to them with greater amperage? 5,7ah is pretty week hence the range can only be 50km without rider. So most probably you’d have 20km range with that size of batteries. If you have 10ah that’d be twice as much. It is just a matter of finding better advanced battery pack.

Hi. How do you figure out this settings without knowing what it does.. Thanks.

Hi.. I am new here. I tried the wire hack connected white socket to the black one. Vola speed incased up in speed 2 : 25km in speed 3: 28km 30km. I’ll double check tomorrow. It feels like the motor reaches at the highest speed in speed 3. I don’t think you can increase any further. other settings mentioned above for P3 also set as mentioned. But I suspect it may change the voltage on the motor. I am not sure about that. P2 is tire size. I’ll check and observe again to see if ideal one is 156 or 160( as in 160mm tire size) that should reflect your speed nothing more. As for trottle I think that can be done if I can find the wire diagram of VK3612YS motor controller unit. Looks like it isn’t sold in Alibaba or AliEXpress. So no information about it. I presumed there is some sort of relay in the motor that is triggered by pedal motion. That can be short circuited with a button extension up to the handlebar. Would definitely be easier to solve it on the motor controller though. second thing the battery is 5,2Ah.Wonder if 10Ah battery available? Any idea. Thanks
