I cut the extension motor cable to access the connections. I put the wheel back on the bike. I discovered the motor windings and hall sensors test good with the tester but only if the wheel moves backwards (bike in reverse). The wheel gear system doesn’t engage if the wheel moves forward so the...

I will probably have to cut open the existing extension cable to get at the wiring for changes. I tried using the cable from the old controller but it wasn’t working managing all those wires temporarily into the new controller socket. Swapping white and red. I would think if the others were...

Just for the record, I have a similar bike with similar issue - no sign of motor control. I think the 5V was bad out of the original controller. The throttle wiring was different with the KT36/48WSRM-ffF02 I tried/bought (Original KT36/48ZWSRM-GP01F7) I tested the motor by itself with one of...

Pin 2 of the Julet motor connector and pin 8 may have to be swapped with the new controller. I will make up a cable between motor and new controller to check swapping these. One has slightly higher voltage - should be the 5v source. I still would like to find the original controller for sale...

No problem, hope they don’t see my garage. I had several projects simultaneously: this bike, a shortwave receiver repair, plant grafting, a dryer repair, and then strong rains… too much stuff in the garage. I lost the star nosepiece for the motor somewhere, not sure if it is really needed...

I pulled off the rear wheel and connected 5V/ground to the hub motor and got no hall sensor outputs at all. I also blew out the throttle receiving circuit in the original controller by forgetting to switch the red/black wires back... :-( So I decided to take the hub motor apart and see what...

I received the LCD control panel and connected it up. Still no indication of power to the motor. It did show a throttle issue on the display so I moved the red and black throttle wires in the controller back as they were and this error went away. But still no power to the motor. Jeez, the...

Explain how the key switch works. It is inside the battery receptor housing and no wires come out from the housing except for the two battery lines. So no issue, right?

https://www.amazon.com/dp/B08T6L18VY?psc=1&ref=ppx_pop_dt_b_product_details I ordered the lcd panel the seller offers to go with it. There are no left over unused wires on the new controller but the brake lines. I tried the pedal connection but no change. It’s pin wiring might be wrong though...

I received a new controller but it shows the same behavior. No noise or motor movement, control panel works. I saw on a YouTube video that I could leave the brake and pedal sensor connections open so that’s how I tried it. The brake input is “low level” on both controllers. The new controller...

I have that tester but it doesn’t have the same controller and motor connections so useless for that. I just ordered a controller from Amazon but it has a review saying what you see is not what you get. I need the round motor/sensor connector type. I haven’t seen another source for a controller…...

Controller Lm-317 good w/15V out. Lm7805 good 5V out. Looks like it is just waiting to be enabled. I think I’ll check out the UI to see if there is an open there. Photos of controller and connections attached. Note that brake connections are 2 wire from brake to 3 wire to controller. Thought...

I suspect there is no 5V to the hall sensor pull-ups in the controller. There probably is a speed sensor in the motor and it’s working. I’ll look closer at the controller circuit to see if I can find a 5V fault. There is a controller on Amazon that seems only to have different power connectors...

Pedal sensor works. 6km button doesn’t help. It blinks if I hold it down several seconds. The user interface seems to work ok. It registers my speed even though the controller is dead to the motor. I went through the controller and test all its caps (ok). I will likely have to buy a new...

Thanks Amberwolf, their website does not seem to have documentation but I’ve left them a request for it. I’ll test the pedal sensor and then reassemble everything and try the 6km button.
