Re: New "TSDZ2 Torque Sensor Central Motor"

tsdz2 it's capable to do 31mph but it's the maximum for the motor... i think to do this for 25miles it's a stress for the motor... I just punched in my data into a bunch of online cycling speed/watt calculators. It looks like I need to maintain 600w for 31mph (49.6 km/h). If I contribute 125w easil...

Re: New "TSDZ2 Torque Sensor Central Motor"

Why would it be a stress for the motor? For the motor it is the same as running 10mph in a lighter gear, slightly uphill. As long as you don't do it while asking it to deliver full power, there shouldn't be any problem. @holophonic seems to be pushing quite hard on his pedals so he won't need to be ...

Argh that is bad news...
I will use that one as a exhibition model in the shop then.

Re: New "TSDZ2 Torque Sensor Central Motor"

In my latest order, I received a mix of motors with silver spiders and black spiders. Up until now all motors I received had black spiders.
Is the silver spider a new version of the motor?

Re: New "TSDZ2 Torque Sensor Central Motor"

I ordered a speed sensor Y cable, and wiring harness for lights to run off of the controller. But the light offered aren't good enough for my purposes. No dyalight strobe, and not designed as a primary headlight for fast night riding. I would like to power an older 350 lumen Niterider offroad headl...

Re: Battery Pack Break-in?

The 36V 10,4Ah packs in my shop have 10s Samsung 26e cells, 1C is the maximum I let my systems pull from it, to assure a long life for my clients. At constant discharge of 1C they get quite warm already. If I remember correctly, the BMS is 20A max on these, but I will not push new batteries to their...

Re: Battery Pack Break-in?

Interesting indeed. I have a professional battery diagnosis machine in my workshop. I could try to run a few monitored discharge-recharge cycles on 2 new 36V 10,4Ah batteries of the same model, from the same batch. One with slow discharge, like 0.3C, and one with fast discharge, like 1C, and see if ...

Re: New "TSDZ2 Torque Sensor Central Motor"

It depends a bit in what (European) country, but the 250w is the nominal power not the maximum power. 90% of the ebikes on the European market go (a lot) over the 250w limit when they are at their highest setting. You will surely know the Bosch motors, their most powerful model, the cx, goes to app...

Re: New "TSDZ2 Torque Sensor Central Motor"

The 250W version has about 7A max (36Vx7A =~250W) and the 350W version about 10A max (10Ax36V =~ 350W). The only difference (as for all I know) is the max A setting in the controller. Thanks Is it a software difference only? I mean, can I flash a new firmware and turn a 250W into a 350W or the othe...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi all, I have a TSDZ2 on my cargo long john bike and I am extremely happy with it. It has the XH18 display and a big 14aH battery. It is the 36v 350W version. Since yesterday it started to behave strange, upon start up, it would work, but after I stop pedaling for a few seconds, the assistance is ...

I’ve a theory about noise which is probably bs but like a guitar, the frame of a bike can act as a sounding box!
That certainly ain't no bs.
Some frames make some motors sound like there's something wrong.
It is all about resonance, just like a guitar indeed.

Nexus 8 adjust (dot align) is in 4th gear also. About the refresh oil of these, Shimano recommend once a year indeed but it all depends on how many it is ridden and in what circumstances.

Re: New "TSDZ2 Torque Sensor Central Motor"

Putting in a 48v controller to use it with a 48v battery doesn't have a big influence on max pedal cadence. One should use a 48v battery on a 36v controller (with modified firmware) for that. I'm pretty sure that is not correct, all advice is to run a 36 motor on a 48 volt battery to get a higher c...

Grand idea today was to fit the new chainring combo so crank puller tightened in place and then the releasing bolt turned and the puller came back out of the crank, the crank completely dethreaded :evil: Anyone any ideas of how to get the crank off?

Re: New "TSDZ2 Torque Sensor Central Motor"

I've read that the TSDZ2 motor is very fast on temperature. Therefore, I was wondering if in the summer, with an outside temperature of 25 degrees, it is possible to cycle for a long time (30min) on 35km/h. This on a flat road. Does anyone have experience with this? It all depends on what version. ...

Re: New "TSDZ2 Torque Sensor Central Motor"

Great stuff, keep it coming!
Thank you for sharing Bartman, quite amazing what the motor can handle when used right.
With that gearing it should have enormous torque!
How did you manage to get the chain line acceptable?

In my humble opinion, this motor isn't suitable for cargo bikes or other heavy loads. It is great stuff and quite well built but (as always) as it is lightweight it isn't very resistant.
