Your bike is set to use thr throttle only without the need to pedal or pas as it’s called that’s why the wheel spins free

Yeah but the throttle doesnt work unless i pull the wheel back. And even then only works about 50 percent of the time. With my weight on it doesnt spin at all.

is the clutch knackered?

The fact you can grip the wheel and it makes that noise with the throttle applied is either a stuck clutch and the freewheel not engaging or the planet gears are stripped.
Remove the wheel and open the motor to inspect.

Just a thought......I wonder have you a phase failure.....This often causes the motor to shudder and reduces power by 66%. On a direct drive, pushing the wheel forward often causes the wheel to turn at reduced power but with a geared motor, this will only work in the reverse direction due to freewheel effect of clutch.
Anyhow, I think its always worthwhile to first check the wiring and especially that the motor connectors are fully connected.

I removed the wheel and opened the hub and everything looked good i think... checked the magnets. All looked good to me. Everything seems fine. I opened the controller and eveything looks good too and all the wires are good. I dont know the clutch, ive been googling. Im abit stuck. What are planet gears? Im sorry for being dumb. Thabks for trying to help though!

I took a quick peek at planetary gears. They seem to run smooth. No probs i can see. Im guessing maybe phase failure or clutch knackered? How do i check these issues? If this helps i attached a different kt controller but kept old cables. Bike worked great for 2 hours and then all the lights on the display kept flashing and then evrything turned off. I thought this was due to incorrect cables attached to kt controller. But evrything worked for 2 hours. Ive ordered a 1to5 kt cable but its gona take a month to come from china. I just dont understand what the issue is!

"is the clutch knackered" I only said that as a maybe.

Because my hub a Bafang swx02 started playing up and would not engage straight away when taking off, scary when pulling out at junctions with no power but would chime in at some point a little later. Took the clutch and planetary gears off the axle and it all worked fine in my hands, and had advice on here "Pedelecs" about maybe this or maybe that. But in the end I bought a new clutch and planetary gears put it on and all OK since. Sorry if this all sounds vague but I had to (guess) work it out my self in the end. My old postings here.........

Strange PAS problem

Evening all, I'm looking for a little advice. I have a Volt pulse rear hub bike with standard PAS ring and thumb throttle. For 90% of the time all works fine. Every so often (maybe 2 or 3 times in a 30 mile ride) the PAS stops working after a short period of coasting (no pedalling). The throttle...

bafang clutch

For those who wonder what`s inside the Bafang hub motor clutch. I have just replaced my misbehaving clutch and although having seen a similar photos on the Webb I thought I`d share mine. Couldn't resist opening it up. I had all the same problems as another member...

My problem does sound very similar. Thanks. Is the clutch around the pedals? I will try and youtube some videos on clutch replacement. Tar

clutch is inside the hub, the other side to the one shown in your photo. Hope you get it fixed "whatever ?" it is.....

Hi. The clutch is a round disk with 3 planet gears mounted on it.
The central "core" of the clutch should rotate freely when turned in one direction and lock up when turned in the other direction.
For a (very !) exploded view of a typical clutch see post #2 and post #6 on my build thread https://www.pedelecs.co.uk/forum/threads/kemp-starley-dutch-town-bike-out-of-hibernation.37181/

Hope it helps, just ask if any questions

Just for the record... i changed the controller, to a kt brushless cobtroller. Changed 1to5 kt cables. And lcd3 kt display. All working so far! Just need to cut and reconnect julet brake cables as turned out female to female connection. Scissoring no good.
