Thanks :) Just ordered a few of these tiny arduinos.. ideal for this job. They are really small and should fit inside the frame i hope. Be here by the weekend. Steve

Yep, the throttle range has about 500 different speeds, just need to see if I can improve the top end. Will really need to get it on the road to see if it achieves 15mph. The last motor struggled up hill, but I'm thinking that's because it was faulty. This new motor is off another non working...

Sorry, updated the video link above... For some reason YouTube was still processing it. All done now. Looking to add finishing of the Arduino code today and taking it out on a test run..

So, after realising the motor was actually faulty (was in the description when I bought the bike) I've had to source another motor. This is only a temp fix as I would like to fix my broken one if possible. Anyway, quick video below. Yes, the back tyre is flat but I wanted to get the video done...

Sent you a pm. :-). Thanks

Most likely put them in the shed and forget about them like all the other things I have..lol, unless I can sell them to recoup some money. Whats the going price for a rim? Although I have just bought another Carrera Vengeance.. opps picking it up at 9pm. so going to use the back wheel off that...

It smells of burning. When I bought the bike the guy said the motor smoked and stopped working. Now I've pulled it a part it really smells of burnt something inside. I've been trying to strip it down but I'm stuck now until my new cassette tool arrives tomorrow. If I can replace the wiring...

Hi all, My back wheel motor is knackered on my Carrera Vengeance.. anyone got a bafang hub I can buy? Thanks, Steve

So I've managed to have a further play now I've found a potentiometer, it was in the last place I looked! Anyway, been playing with the pulse range to see if I can get some sort of control. I can but I'm not sure if my motor is already damaged as it's vibrating quite a lot at high speed and...

Sadly can't find a potentiometer to test, although I have wrote the code ready. I'll have another look tonight maybe.

Thanks, email sent. I'll do some more testing this morning to see if I can get a variable speed controller set up via a potentiometer and an Arduino. Will posts the results later. Steve

Yeah, happy to give it a go. Ideally the system would run on 5v.. so if the throttle is just a potentiometer then I see no reason why it wouldn't work. My current sensor is a 12 magnet type. I've found a compatible one on Amazon for £18 but would need to swap the plug over. It would be nice to...

So.. just to see if I was correct. I've programmed an arduino up and loaded a simple 'blink sketch' like below void loop() { digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level) delay(50); // wait for a second digitalWrite(LED_BUILTIN...

Evening all, I've just purchased a poorly Vengeance E. The fault it came with was the motor didn't work and it had a very poor repair on the wires going into it. I've now re-done these and I'm happy to say when I press the walk button at the front the rear wheel now moves as expected...
