If your pick up still suffers from intermittency in use then look at your PAS fitting and C1 settings. I changed my 12 pole PAS disc to a 10 pole one and found PAS worked so much better, the KT appears not to always like 12 pole counts.

The internal gearing is simple, the metal hub body has the large outer gear machined to the body and the main motor /clutch mechanism has the nylon planet gear's that sit centrally. The planet gears are a two stage stepped gear unlike Bafangs/others which have a one stage gear, there is no gear...

One thing you MUST do before attempting to carry out any connections is to confirm with a meter that the battery polarity is correct other wise you will see a flash and possibly KFF's. It has been known for China batteries to have reverse polarity, any miss connection can damage the battery and...

37 volts is approx. 50% charge and not 100%, you need to plug it in to charge up and should see 41.5 - 42v for a fully charged 36v battery. You can't discharge a lion battery to a safe level other wise it would be only fit for recycling, even at minimum voltage (30 - 32v) a battery will still...

I had motor issues due to incorrect P1 figure, not complete motor cut out but more of a delayed slow motor pick up. d8veh AKA vfr400 I think also posted along the same line in the thread that was running. I solved the motor pick up by setting the odometer reading to read correctly which gave...

4816 means 48v & 16" rim. Only an assumption; 19 = Year so 2019 07 = Month so July 2 or 20 Day of month ? 01002 = Line number/construction number.

If you can change the battery rack position you should notice the change in handling.

Any bike with a marked motor > 250w will always be illegal no matter what controller is used.

Some bikes handle better then others with a rear rack battery. My Boardman has a downtube battery (522wh) and a 974wh self build battery I use in a top bag to me the handling is good , it is only awkward when pushing the bike at times or at low speed on more technical terrain. With a rear...

The controller doesn't affect RPM of the hub, only the watts output depending on the amperage. Voltage does, If you run it at 48v you will see a 33% speed increase over 36v.

BMS have been known to get their labelling wrong. I and a few others bought the Q128C/AKM 128c with a 201rpm winding which should be about 15 /16mph but in use it was capable of 19/20 so in fact was a 250/260 rpm winding.

All of the big 5 or 6 make some great cells also they make cells not so great, you can't simply just say they are made by xxx company. The exact cell spec/designation needs to be known to make a statement to how good they are. LG and Murata make the best 10a + cells in my view. Panny cells are...

Factor in depreciation of 55% for a 4 y/o bike and 60% fro 5 y/o, on top of that subtract the cost of a new battery.

Why do you want a rear battery ?

How many poles does the PAS use ?

I would start again disconnect every thing and just connect the display and PAS to see if it works also double check the motor wire connector and that it is positively push home to the raised line marked, there are embossed arrows for correct alignment. Once you get the hub working add one...

The controller is correct one for your sensored hub. The 03 error could be a faulty sense wire connection in the white hall block or even a broken wire from the controller, a continuity check on the controller sense wires would confirm good or bad any issue. Though you would need to disconnect...

How do you know it's is 250rpm ?

If not Woosh then look at Wipser in 7oaks they have there new Wayfarer models due out soon and comes in many guises, the mid drive is by Shengyi I believe.

Throttle is ok then. Does the system work ok or does the error prevent operation ?
