48V and soon I will switch to 52V.
Is there anything special that you'll need to address for 52v with your firmware?

I have been reading the wiki and it seems to indicate nothing specific to the 52v because it's physically the same as the 48v.

Re: New "TSDZ2 Torque Sensor Central Motor"

"The only issue I have had so far was a loose left crank arm that may have been my own fault (though I do recall torquing it correctly)." This is an all too common occurrence with square taper cranks set up from new. You can torque them down to spec while building the system but even after a short ...

Re: New "TSDZ2 Torque Sensor Central Motor"

Been lurking here long time thinking to buy TSDZ2 or Bafang motor. Reason I've been afraid to end up buing are all these maintenance issues, issues with nylon gear etc. I've been reading about. I would be only using it for on-road work commuting and would prefer TSDZ2 for torque sensor. I would app...

Re: New "TSDZ2 Torque Sensor Central Motor"

Even taking the cover off to relube the gears, breaks the warranty seal. ... For anyone that may be hoping for supplier support in the future. :? FTC seems to indicate that explicitly denying warranty in that manner is illegal: https://www.ftc.gov/news-events/press-releases/2018/04/ftc-staff-warns-...

Maybe for gears but not for bearings. Bearings love grease :) ..unless they are sealed , prelubed, bearings, as many are these days. (no idea about these though) In that case , relubrication can reduce service life. Even taking the cover off to relube the gears, breaks the warranty seal. ... For an...

Re: tsdz2 problem?

Hi all, first post here. I've been running a BBS02 and a 52V luna shark on my Trek 8.4DS since last November, and love it. I was intrigued by the tsdz2 and after reading this entire thread (100 pages as of this writing) I bought a 52v unit from Ebird on amazon. I've got it on the bike now but motor...

Re: New "TSDZ2 Torque Sensor Central Motor"

I had to remove the torque arm so I could rotate the motor another couple mm to skip the protruding part. I guess I’ll throw some zip ties through the hole for now. There is a small rubbing sound once per revolution of the pedals looks like the chainring hitting the plastic a tiny bit. Anyone else ...

Re: New "TSDZ2 Torque Sensor Central Motor"

Switched to the long screws with double spacers did a little twisting and it looks less than 1mm off now. You should try to twist some more I think. That drive side should be firmly up against the bottom bracket shell. If you can twist more, see if that protrusion can swing away from the drive side...

Re: New "TSDZ2 Torque Sensor Central Motor"

Well, at least the cranks I got, 4 of them, were all market with L on backside. And I had to open a second pair of pedals because the right on me was not threading and so I had to put another left pedal on the right side. Or I did something wrong?? You cannot put an R pedal in an L crank arm. As bi...

I did some quick tests on an accentuated climb. Assist level 1: max around 6 amps Assist level 2: max around 12 amps Assist level 3: max around 18.4 amps Assist level 4: max around 18.4 amps Maybe the difference between 3 and 4 is speed limit and not current limit. Nice, I think the difference betw...

Re: New "TSDZ2 Torque Sensor Central Motor"

Thanks, i'm thinking the 500w is a better choice to start with, as i don't want to cook the tiny motor, and strip the gears. I'm guessing the 500watt is set at 10amps and the 750 at 15amps. I think the nylon gear is fine for 750w if you stay in the upper 25% or so of the motor's RPM range. What I d...

Re: New "TSDZ2 Torque Sensor Central Motor"

Reached about 100 mi of road-only commuting and seemed to have developed some crank slop which I think is making an intermittent noise. Grabbing the crank arm ends and moving them toward and away from the frame show movement. Crank arm bolts were all properly torqued. Motor housing is solidly mounte...

Re: New "TSDZ2 Torque Sensor Central Motor"

If you're using a typical style rear derailleur and cassette you should not have any issues shifting under load. The bottom of the chain is not in much tension regardless of motor output.

Re: New "TSDZ2 Torque Sensor Central Motor"

Don't suppose anyone could tell me a little more about my particular motor.... I saw some labels earlier in the thread indicating that there is a 52v version that runs at 4500rpm, is that one an 18a limit? My motor is labeled 52v 4000rpm, so I am not exactly sure what I should set my current limit v...

Re: New "TSDZ2 Torque Sensor Central Motor"

I also run a Bafang crank arm on the right side to help balance the offsets. It looks slightly different but not noticable. They are almost completely straight with no offset. Anything less offset and your heel would hit the crank arm. What about the Shimano step e6000 cranks? Are they staggered of...

Re: New "TSDZ2 Torque Sensor Central Motor"

Given the rpm/cadence upper assist limit is a function of motor speed, is there a chance that we can change the internal gearing of the unit to move the power band?

In particular, you had to move the rear derailleur cable into a full length housing, but would I likely...
