Re: New "TSDZ2 Torque Sensor Central Motor"

Right now, I’m going to give this thing a few more tries and then remove it from the bike. Quite frankly, it’s slowing me down as I can actually maintain 20-22mph on a road bike for. 60 minutes straight without much issue, I just end up sweaty as hell. This thing overheats about 15 minutes or 3 mil...

Re: New "TSDZ2 Torque Sensor Central Motor"

If they haven't cured the noise & drag I'll just go with a BBS02. Maybe my TSDZ2 is somewhat noisy despite being a newer one with helical gears, but I've tested / cycled beside a few different BBS02s, and they are all much quieter. The drag comes from the fact that when you turn the cranks with...

Re: New "TSDZ2 Torque Sensor Central Motor"

1. The back wheel will not free wheel at all, it feels very stiff, if i want to reverse I have to lift the back wheel.

Re: New "TSDZ2 Torque Sensor Central Motor"

Re: New "TSDZ2 Torque Sensor Central Motor"

All modifications to reduce noise discussed in this forum are for users who are using their TSDZ2 engine to its maximum. And it is quite correct. I have the TSDZ2 myself, and at low power (100-250w), it is definitely audible (not particularly bothersome though). I have also briefly tested two diffe...

Re: New "TSDZ2 Torque Sensor Central Motor"

I apologize for the following question:.. The actual motor has 3 thick wires blue, green and yellow. Can the battery be connected to (which) 2 of these in order to see if the motor works or if it is broken? My intention would be to simply.make the motor run.b applying voltage directly to it to see ...

I don’t know if you have a thread/post already working on a custom firmware for the bafang ultra ? You’d be the right man for that! Thanks for all your work on the tsdz.

Re: New "TSDZ2 Torque Sensor Central Motor"

Do you have any ideas what could be wrong? Why did it burn? Why only green wire was affected? I already replaced the inner motor with the new one and everything is working fine again (so far I have about 100km on it). But I'm a little bit afraid the the core problem is somewhere else and it may bur...

Re: New "TSDZ2 Torque Sensor Central Motor"

1. It's too much for the motor controller or the wires for 6V output which are very thin. Use a relay or another switch to turn on the lights and connect them straight to the battery. Thanks for the reply. Although I am not sure if I want to go that route, at least yet. I'd prefer to use the contro...

Re: Hardware temperature control tsdz2

Re: New "TSDZ2 Torque Sensor Central Motor"

Re: New "TSDZ2 Torque Sensor Central Motor"

Clean and grease the main gear and the small gear driving it. The small gear is connected to the blue gear and maybe there's a problem with the one-way clutch in the blue gear? If that's not working, you're moving the whole gear chain and the motor when pedalling and it would create a lot of resist...
