TSDZ2 Cold morning start.

Featured Replies

This as happened twice now I Have Turned on the Battery let it settle for 10 seconds without touching the pedals, I have then pressed

the throttle button and although you can see the motor trying to work it starts and stops very slowly I keep trying this for about 10 minutes and

eventually it will works flawlessly. The magnet and sensor are in the correct position because when it finally starts to work it is great.

This has happened after a fully charged battery and used the bike on cold mornings. I am just wondering if I need to insulate the motor in the garage.

It is said you need to leave TSDZ for 30 seconds after switching on without touching the cranks to allow for system initialising/calibration then you should be good to go.
I find that it needs a good 30 sec I power up then put gloves on etc, not good if you need a quick getaway

Just an update on the problem i have, It seems the motor does not kick in after a fully charged battery, but after about 10 mins of trying to get the motor to work it is totally fine. If i don,t charge the battery it works first time.

Any ideas anybody.

If the battery is fresh off the charger it could be an over volt protection, what motor do you have, and can you check the battery voltage

I have the the tsdz2 250w 48v i have checked the voltage and it is reading 52v after a full charge

Edited by suggy

That should be ok at 52v hot off the charger so far I have been lucky with mine, but must admit for my current build I have gone with a bafang

At least i know what the problem is now and it is not the motor which i was worried about.

I just need to drain a little bit of the battery after a full charge somehow which is going to be a pain.

Can you also check the charger volts output most have a pot inside to set /adjust

I am just surprised that nobody else has had this problem.

I am going to leave the battery for 24 hours after a full charge and see if it works.

Some body has he tried a 52v battery on 48v settings, problem solved when he reprogramed ,showed same symptoms as yours not as many people use the tsdz2 compared to other brands
52v hot off the charger is only warm for a 48v battery is should be 54.6v, the issue may be that the battery is unbalanced. 52v charge equates to 4v per string but one or more may be unbalanced if that is the case.
That's still a bit low for what it should be, indicating that all is not as good as it should be in the battery department, though I doubt that it has anything to do with your problem.

I have just spoken to the supplier and he said if it does not work at 56v but works at 52v it most likely

the controller is faulty.

My supplier wants me to take a picture of the controller inside mid drive and going to send me a new controller.

Just wondering is it difficult to change the tsdz2 controller.

Who said anything about 56v ?

56 V is to high will be above the upper cut off not had mine apart yet but did spot a how to vid on youtube

Who said anything about 56v ?

The supplier. What he's saying is that it should be OK with a 48v battery. It can go as high as 56v before it throws a wobbly. If it doesn't work at 52v, he's saying that something is wrong with it.

The controller problem has appeared on 750watt 48 versions some are flashed wrong , the display and controller do not match versions
