    New "TSDZ2 Torque Sensor Central Motor"

    I'm out of ideas sorry, but want to say you did an excellent job with the lights. I don't know if the metal shavings would cause that error, but if they got into the motor or other electrical contacts then it can't be healthy. A few people have posted about their brass gear being chewed up even...

    My attempt at a lightweight EMTB with torque based PAS

    So when you start pedalling it gives you a flat ~20W assist? Or does it vary up to that amount depending on the torque applied?

    Bafang M500/M600 thread

    Is there a full list somewhere of what settings are editable through the BESST software, or is that all?

    New "TSDZ2 Torque Sensor Central Motor"

    Looking at the disassembled motor in front of me, it seems like outward pressure on the torque sensor assembly would instead be the cause of this. The roller bearing slides freely over the torque sensor shaft and is a press fit up to the lip inside the motor case which does not contact the...

    Bafang G310 geared hub - 11:1 reduction ratio!!!

    The Phaserunner looks great. After further research I now understand a lot more about the capabilities of hub motors. They seem like a much neater and more practical solution so I'd still like to play around with one. But perhaps sticking with a mid-drive might be best for this bike so now I...

    Bafang G310 geared hub - 11:1 reduction ratio!!!

    It looks like the GMAC is worth investigating further too. So far my only experience is with the TSDZ2 mid-drive, so I'm trying to work out just what's possible with these small geared hub motors. More of a general question, it looks like it's possible to run most hub motors on the voltage of...

    Bafang G310 geared hub - 11:1 reduction ratio!!!

    It just needs to satisfy a cursory glance, so that's an option. Are there any other markings on the motor at all?

    Bafang G310 geared hub - 11:1 reduction ratio!!!

    Thanks, no I hadn't seen that and it looks like an interesting project. Although the GMAC motor seems to be a little larger and heavier, and I'm trying to find the least obtrusive motor as possible and at least give the appearance of adhering to 250W regulations. But I see varying info about the...

    Bafang G310 geared hub - 11:1 reduction ratio!!!

    I'm considering this motor for a cargo bike of around 130kg loaded. I'm only experienced with mid-drives so I've been reading up about hub motors and it sounds like most people run them with a throttle and at high speed. I'd be using a torque sensing bottom bracket and expect to contribute a...

    My attempt at a lightweight EMTB with torque based PAS

    Fantastic work there and I'd love to see a video of it in operation and some more close up photos. Having those CYC parts available sure helps. What is the drag like when pedalling with the motor off, does the freewheel totally disconnect the drive system? I'm looking for something like that to...

    New "TSDZ2 Torque Sensor Central Motor"

    I wouldn't touch the sprag clutch or roller clutch inside the blue gear in case they start slipping. But since you are in the UK, the easiest solution is to order a small container of Molycote PG-75 from Performance Line Bearings and use that for everything else as it's safe for plastic gears...

    New "TSDZ2 Torque Sensor Central Motor"

    It looks more like the material was never fitted to begin with. I've never seen a replacement for sale like that, but someone else's failed and was missing the material too. Perhaps the constant friction has caused yours to overheat and crack. But 8000km is a good distance if this is your first...

    New "TSDZ2 Torque Sensor Central Motor"

    I have 2 of those teflon washers on my motor, 0.4mm and 0.5mm. I think they weren't even present at all on older motors and were probably added due to the change in the torque sensor design which raises the sprag clutch and big gear off the sensor disc without using brass shim washers...

    TSDZ2 120mm Axle Broke for the 2nd time on my Fatbike

    There are a few factors but the most obvious is that the machining of the circlip grooves causes internal stresses in the metal. The sharp internal corners are stress concentration points. It's not the circlips themselves. The only way to fix it properly is to redesign the spindle and motor case...

    New "TSDZ2 Torque Sensor Central Motor"

    Have a look at the plastic cable cover and see if you have any wear over the pinion gear area. Do you know if your motor is the original model with straight gears or the new model with helical gears? If it's the newer model have a read of this, it really needs some modifications to reduce the...

    New "TSDZ2 Torque Sensor Central Motor"

    I posted about this a while back, it's from the the Tongsheng VLCD5 manual regarding the hidden service menu. Without any pressure on the pedals, the recommended initial value for the torque sensor should be within the range of 50-105. When I first read this I misinterpreted it to be the range...

    Bafang M500/M600 thread

    Has anybody here managed to put some high mileage on one of these motors yet and are they generally reliable? Do the factory and Luna plastic gears hold up ok? Also do these have much drag when pedalling unassisted with the motor off?

    New "TSDZ2 Torque Sensor Central Motor"

    Are the gear sensors simple momentary switches or do they have some kind of timer circuitry built in? I read some complaints about them cutting power for a couple of seconds, but can't remember if that was in relation to the TSDZ2 or Bafang motors.

    TSDZ2 repair - need advice

    This seller only supplies two springs with the newer version, but it would be good to get confirmation from someone who had it from the factory. https://www.aliexpress.com/i/4000680824444.html Not coming with the teflon discs is a annoying, I have been told they are not available. One of mine...

    TSDZ2 repair - need advice

    Did the replacement come with three springs? I suspect this is all a known problem, removing the nipple is hardly likely to be a cost-cutting exercise.

    TSDZ2 repair - need advice

    Was the missing nipple the one next to the wire like in this photo? It's a newer version and they have intentionally removed it, although my late model motor still has the 3 nipple version. Since it's the one closest to the pinion gear, I can only theorize that it must be something related to...

    TSDZ2 repair - need advice

    I couldn't get mine out using the vice, but I think I was trying to push it the wrong way. There's a lip on the inner side of the big gear opening that stops the sprag clutch sliding in too far. So I used a hydraulic press which did it easily. However I see there was retaining compound added to...

    New "TSDZ2 Torque Sensor Central Motor"

    So I took a chance and removed the silicone rubber. Yes there are solder pads for the torque sensor coil under there and it looks like the best place for disconnecting the wires if you want to replace the roller bearing.

    New "TSDZ2 Torque Sensor Central Motor"

    Are there solder pads under the rubber here? How are the red and black wires connected to the coil? I want to disconnect them without cutting the wires if possible.
