Hi again, I managed to break the lcd while installing the KT controller so I haven't been able to run the bike with it. I have been running the bafang controller with an external speed sensor, but since the controller only supports minimum 6 magnets for the speed measurement I get 1/6th of...

For reference I had to change the C1 setting in the KT controller to 05 for my PAS to work. I could not make the throttle work by using a potentiometer, using any of the P4 or C4 settings. It's non-important since I'll use the pedals to start anyway. The bike definitely feels snappier with the...

Hi, I have a Bafang rear hub motor SWX02 with a Bafang controller and the c961 lcd. The motor is 250W 36V and I have a 11.6ah battery pack. A couple of weeks ago the speed sensor failed, there was no signal coming from the motor. I opened up the controller and installed an external speed...

Unfortunately my display (c961) does not have that option. 6 magnets on the wheel then? :)

I have pulled the speed signal cable, and connect +5V and ground in the controller. I attached the speed sensor and by passing the magnet I can see the signal works. Unfortunately I think the signal is quite weak? By passing the magnet back and forth fast I get about 5km/h in the display. If I...

My controlled is inside an aluminium box. I will need to pull the 5v and ground as well from the PAS connections, right?

Thanks, I guess I can bypass the speed sensor in the motor with an external one, and attach that to the controller. Got one of these lying around: http://www.pswpower.com/peng/iview.asp?KeyID=dtpic-2016-38-4F9M.91FDM

Hi, I have a cargo bike with a Bafang rear hub motor SWX02 and a bafang controller. During one of my commutes the bike suddenly stopped reporting speed and the display says error 21 and turns off. I am wondering if the speed is reported by the pas sensor? The controller detects pedalling so pas...

Perfect! These are the connectors I was looking for apart from the motor. The panda one is for the motor. I got the answers I was looking for, thanks!

Hi guys, I have a cargo bike like this one - http://www.cargobike.se/produkt/Cargobike-Classic-Electric- I have bought a new controller to test out from KT but it seems my motor is sensored and I bought the non-sensored controller. Nonetheless it would be nice to test how the bike performs with...

Thank you for the detailed explanation, it was very useful. I can see the bundle of wires going out from the controller into the engine have 3 thick (yellow, green, blue) and 3 thin wires (red, yellow, blue). I went ahead and did the shunt mod. Picture before and after are below. Was my first...

Hi guys, I found a nice entry level ebike at a store sale for about 700 euros and decided to bring it home. This is the bike: http://whitebikes.com/bikes/velo-city-energy-spike/ Overall I am quite happy with it, apart from some quirks. The bike seems to take about 3-4 seconds pedalling before...
