Question:While trying to get the hub motor up and running here we have run in to some problems. After installing the hub motor wheel in the fork it was very sluggish to turn and took quite a bit of effort, not freewheeling at all. The first time we plugged the battery (fully charged 48V 12AH LiFePo4 at 52.9V) in to hub motor (without the throttle connected to the controller cable) the hub motor beeped three times. When we hooked up the controller cable black and yellow pin connectors to the corresponding ones on the throttle there was no response from the electric bike motor, but the battery level lights did light up. We tried both throttles sent with the same results.

As it was the weekend I went to the forum and looked there for assistance. I received some good feedback that the 3 beeps we heard were a signal that the throttle was not work which is what we found as soon as we hooked up the throttle. We have checked all the leads for correct amperage as per his instructions with positive results.

I am assuming that electric bike kit is bench tested before it leave there? The packaging was undamaged upon delivery and all seemed in good order upon receipt. If you could please advise us on what to do to get this resolved we would appreciate it as we want to get on with our trials here to be able to get out product to market by summer.

I have checked my throttle and hub motor controller wires against your PDF diagram and there seems to be some discrepancy? I wish my camera was working but I will describe my findings. Diagram Throttle Black 3 pin shows: Red? perhaps Orange?/White/Blue Our Throttle Black 3 pin has:
Orange/White/Black from core with black jump to yellow 2 pin Diagram Controller Black 3 pin has: Red? perhaps Orange?/black/Yellow Hub Motor Controller Black 3 pin has: Rust from Core with Red Jumper to PAS White three pin/White/Black from core with Black jumper to yellow 2 pin

I checked the 8 pin connector again and can’t see that it isn’t making good contact. No bent pins or obstructions.Electric Bike Motor still beeps three times upon connecting to full battery as described with and without full connections of cables.

Yes jumping the two holes as indicated does make the electric bike kit run. It seemed like at first that by moving the controller wire that the electric bike motor would stop and start as if there was a short right at the junction and we thought that might be the problem. We hooked up the cable but I still am not getting any response from either throttle when hooked up to the black two pin connector even if I move the cable at the junction and now using the jumper the short method that issues seems to have gone away?

We are trying hard to make this electric bike kit work here but I have to admit we are getting a bit frustrated. The throttle cable while hooked up shows 5.0 amps on the red wire and from .8 amps at rest and 3.8 amps on the white wire when at full throttle like it should? Without the black pin connector together there are 5.0 amps at the red wire and .1 amps at the white wire if that is any useful information.
