Re: New "TSDZ2 Torque Sensor Central Motor"

Thanks for the interesting use report on the brass gear. After hearing all of the blue gear destruction talk shortly after buying and installing our TSDZ2, I almost bought a brass gear to replace the blue preemptively, just to save some downstream frustration. I never did, and now certain to stay w...

What grease did you use for the new blue gear?

Sorry for the delay! I just used general automotive grease - I can't remember exactly which one, probably valvoline.

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi all, Just throwing out a quick line or two about my experience with the brass vs blue plastic gears. I have the 750W 48V TSDZ2. Rode the original blue plastic gear for a good 2000km before it crapped out. Thought I would give the brass gear a go as I thought it would be more durable. Not so! It l...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Hi all, I've just finished my 2nd TSDZ2 build. This 2nd bike is for my girlfriend, but I mucked up. She wanted the same as I had, and I have the 8-pin unit and a throttle, but I never use the throttle. So I just ordered the 6-pin version for her. Big mistake! Turns out that was the function she was ...

Re: New "TSDZ2 Torque Sensor Central Motor"

I have found on both my BBS02 and wife's TSDZ2, my average commute speed increases modestly, say 5km/h, but simultaneously, my effort goes down. So in all, my overall commute time is quite similar, but I arrive less sweaty. So I think ebikes aren't saving much time, but saving much effort. If I put...

Re: New "TSDZ2 Torque Sensor Central Motor"

I am definitely over complicating that, although that is the type of calculations some of these higher end mid drives make, correct? So, just out of curiosity, what higher end motors could take a bit of thrashing? I think the TSDZ2 is very good value for money but it's probably not quite what I was...

It looks like the plastic cover over the big gear may not be seated properly, you would need to remove the chainring to seat it properly.
Thanks, wonder why that happened. Will have a look when I get a chance.

Re: New "TSDZ2 Torque Sensor Central Motor"

Does anyone else have a slight gap underneath their motor near the chainring?

It seems to be slightly open (see motor chassis between wires and chainring):

Just wondering if I'm putting some kind of undue strain on the motor chassis to cause this?

Re: New "TSDZ2 Torque Sensor Central Motor"

I would be careful with the metal gear too as we do not yet know what will be the next weakest link down the line. The nylon gear protects the rest of the motor from damage. Very good point. We go pretty fast from a start. Make sure you are in 1st gear and ease into your torque and you should be fi...

Re: New "TSDZ2 Torque Sensor Central Motor"

Starting in a higher gear is not good for the blue gear. You want to start off iWhat is really bad for the blue gear is torque at slow rpms and braking with the motor still going. This is really going to take some adjusting I think - I'm so used to just ticking over on the highest gear and tickling...

Hmm, yeah, it's getting harder and harder to get in now. I was lucky that I got my residency before they upped the requirements (I'm from the UK originally).

My battery arrived! :D

Just wanted to say thanks to recycles-ebike.com for a such a speedy delivery!

I'm based in NZ and my delivery times were:

- 13 days from placing order for the TSDZ2 motor
- 16 days from placing order for the battery

Re: New "TSDZ2 Torque Sensor Central Motor"

the bell lights themselves run on batteries, I open them up, place my own flat LED/PCB with wires, then connect directly to the TSDZ2 6v light wires... Great, gotcha. I had a look at the LEDs you linked to - the 5W ones say they operate on 6V but the 1W and 3W operate on 3V. Would these still be ok...

I paid $6.40 for my light :) The light lead is the 4' long wire that connects to that double connector (that puzzled you earlier) and then forks into 2 wires each with 2 connectors. I tested the light first on the usb and it would not turn on due to low amperage, but it was bright on the 6v light l...

Very nice! Do you have a link to purchase the bell lights?

So you don't need a DC-DC converter for these?

I have not mounted it yet but this cheap light does work with the 6v power lead wires and it seems fairly bright for being only 6v. The rubber band mounting has much to be desired but I will probably mod it somehow when I get around to it. It does not work with the usb power coming off the display ...

The fixing block was more unnecessary parts for me :) My FS bike won't allow it to work, but the motor isn't moving on me with just a hd cable tie holding it in place.
