Pedal assist before throttle does not work. I will measure the throttle resistance. Thanks for the info. I am trying to borrow another controller to swap in.
I measured between the black and green on the throttle and red to green at the controller connector.
Both return 32 megs with no change with lever position.
Bad throttle?

Hi, I’m new to this forum.

I’m trying to use the 3-wire throttle (black, red, white) with the Wuxing 29DX 5-wire connector (black, brown, orange, white, green).

Which wires do I splice together?

I’ll attach photos.

Thanks in advance

Thanks a lot, @Alan all this help is highly appreciated, I usually repair graphic cards in spare time, but this board got me talking to my gpt more than to myself. I had to reverse engineer the whole thing until I found out I was wrongly thinking signal wire is the GND wire. Was a very hard learning.

After all, the second board is fully functional now.

Thanks again, if you know where I can get this SMP5-20150702.OC8 firmware it would be helpful, otherwise not sure if its dump-able, but should be I think .

Hi andto the forum.

ebikes.ca produce a torque arm that is designed to use existing eyelet mounts on either the rear frame or the front fork.

Check out the TorqArm V5 on their website or watch the YouTube video here.

You can even download a full scale drawing to enable you to print and cut out the pieces to test the fit on your bike before purchasing.

I think the V6 or V7 TorqArms would be a much better choice as they transfer the torsional force much further away from the dropouts, which should greatly reduce any chance of the dropout breaking due to metal fatigue from the bidirectional axle torque being constantly applied directly to it during both power and regen, which the dropouts were never designed to withstand.
