I've got it working now, the sketch was very helpful. There are two connectors which fitted the throttle, I had plugged it into the one that went directly to the controller. That was why it gave me 36V, not 5V. So thanks for the help.

Hi, i've tried this and it's not working. I wonder if I misunderstood you. There is 36volts across the red and black wires. I have divided this down with resistors to about 3.5volt and switched this voltage onto the blue wire. it does nothing but the system still works but as before. The P1...

Hi, is there any consensus on the reliability/ useability on one of these hubs in a 250 watt transmission?

Ok , good, that is most helpful, thank you.

Hi, thank you. Is it possible to use an ON/Off pushbutton instead of the thumb throttle?

Thank you. It sounds like it would certainly be worth doing. What about the scenario when you have to stop on a hill and can't get pedalling at all so that the PA S sensor will start the motor?

Hello, I would like to have this facility. Please could you explain it in more detail. The throttle I got with the psw power kit is a thumb throttle and I never fitted it because I understood that this was illegal in the UK. I don't know how to reprogramme the controller either. Thank you.

Thank you, I've got the motor running but it shows only 34kph on the display. Is there a way to reset it? I don't think it's going at maximum speed. Attached pics of the frewheel chainset and bike frame. There is a problem connecting the controller to the motor. The motor connector has 9...

Hi, I've made a freewheel chainset. The question is what sprockets would work best? I have a 24T and a 34T which I have bolted onto the toothless freewheel. I made an adapter to screw it onto the crank which is a steel one from from a really cheapo chainset I had. I was wondering what the...

Hi , I see now that the crank has to freewheel, whereas you don't need a freewheel on the motor. I can just loctite the sprocket on the motor to its thread. If I use 638 it'll never come loose or i could use nut locking grade which would enable me to remove it. I have a fixie that will fit...

Phew, doing that is high tech for me!

I have done a sketch and took a pic of the crankcase

Thank you, that's a really helpful reply and the link looks just about what I am trying to do. I can't make out the pic in #9 very clearly but the bike in pic#13 is , expect for the overall look of the thing, what I want to make. Are you d8veh? If I understand the thing are you saying that...

Hi, this is a new project I am looking at. I don't know if you are familiar with the Kosynier ebike? I'm making one like it but with the motor actually inside the V twin instead of in the back wheel. To get the chain lines to work you would need to run a chain from both sides of the motor...

That's great thank you. I did get the controller with lots of wires and little connectors fortuneately. The motor is just a motor and I'm using it as a mid drive. I'm only thinking of changing the rotation because I have two chains that might foul each other. One is a on a fixie sprocket...
