Re: tsdz2 torque sensor broken

@andrea_104kg - blue cog was ok, and I suspect the internal bearing is ok. Ordered metal one and a spare blue one, and there's no change. Chinese vendor not much use - timezone, language, etc. Put the motor into test mode for torque, and readings suggest its ok. But I get no power assist. Feels like...

Re: TongSheng Chainwheel offset - dropped chain

Well replaced blue gear with metal, and no change. Still don't get power. Have asked for help/ guidance on the other longer thread, but will continue to post on here. Its either the clutch bearing (noting it doesn't seem to align to the wiki symptoms i.e. peddles do not slip) or the PAS ... I do won...

Re: New "TSDZ2 Torque Sensor Central Motor"

Diagnosis help please? Commuting prior to Christmas and the motor started to make a horrible loud noise, and lost power/ assist. Spoke to the seller (aliexpress), read the wiki, and it pointed towards the blue gear. After incident, the noise abated, but no assist...so I ordered new gear. Replaced bl...

Re: tsdz2 torque sensor broken

Keen to get updates please, as I think my sensor is gone also. Was riding, got a higher pitched grrr sound, and not the motor provides no assist ... Re/re1 readings are 90/99. My crank also had play, and prior motor was running after I had come to a stop ... seemed as though this might be a progress...

Re: TongSheng Chainwheel offset - dropped chain

Thanks for the steer. Anyone replaced one of these clutches? Is it best to change the individual bearing $15 or the complete assembly $50? I don't have a bearing remover tool. Might see if a local mechanic might be able to do it. Other the later is the only option. Still talking to the supplier to g...

Re: TongSheng Chainwheel offset - dropped chain

Took the motor apart and no signs of damage to cogs, so cleaned and put back together. Same outcome. Here's a video ... first off no power assist (no noise), and then full (cog noise)...although the motor provides no assistance what so ever. https://1drv.ms/u/s!AgJzHivwxSoWgekkJ6hX6RXfpm0Fqw?e=slSNL...

Re: TongSheng Chainwheel offset - dropped chain

Done 1350 kms, and this evening I suddenly get a grinding feeling through the pedal, and a higher/ louder pitched noise from the motor, and a loss in power. I assume the plastic gear is buggered. Don't have time to take motor apart, but am I on the right track? Must admit ... a bit disappointed its ...

Re: TongSheng Chainwheel offset - dropped chain

Have ordered the replacement display and Rs232/ USB ... so will find out soon.

Still having a few dropped chains, so will be checking chain length again, and maybe shorten a bit more ... seems to be a bit of an art to this.

Re: TongSheng Chainwheel offset - dropped chain

Thought I'd give an update. Reducing the size of the chain seems to have fixed it. But will ride over the next 2 weeks and then provide an update. Haven't changed the stock chain ring. Still feels offset to middle gear would improve, and so still might try lekkie at some point. Will update in a coup...

Re: TongSheng Chainwheel offset - dropped chain

re 2old ... "Sorry if I was obtuse" ... my ignorance more like fella... Ok. so you offset the chainring to the far right which I assume means getting it closer to the frame, which I think is what BigWheels suggestion is. And I assume the best way is to manufacture or find a chain ring with offset li...

Been looking around a bit more on chain rings, and thinking of trying the Lekkie Bling Ring HD ... anyone tried to connect to a TongSheng? https://www.burkescycles.co.nz/products/lekkie-bling-ring-hd?s=recomatic Seems like a popular choice for the Bafang's BS.

Re: TongSheng Chainwheel offset - dropped chain

Must admit, even in the limited gears, I am impressed with the TongSheng ... currently have a Haibike with Yammy motor .. very good, but heavy and limited battery, especially as I've now done 7000kms and will need a new battery. NZD1600, without shipping and gst. So keen to get this issue solved, so...

Re: TongSheng Chainwheel offset - dropped chain

Hi. Thanks for the responses ... I am not a mechanic and just started out my journey, so might need some more specific direction please. So option #1 seems like find a chain ring with inward offset to bring the chain ring effectively closer to the frame. There's not much distance between my current ...

Chainring offset.PNG Hi. Sorry if this has been covered before - I am just coming to the end of my initial build, and the chain keeps slipping off the chainring, I assume because of the cassette offset against the std TongSheng chainring. See pictures. best approach? The motor is flat again the cra...
