    New "TSDZ2 Torque Sensor Central Motor"

    Hope you guys can help me on this. I have been struggling a couple of days with my motor. After hearing creaking noise (for sure not the pedal or crank) on the drive side I decided to open it and see if I could regrease and at the same time check the bearing condition. The problem is that I...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Hi everyone, Did any of you install the software on the coaster brake version? I installed it a couple of months back to see and the motor was still on half a second after I stopped to pedal. It was quite annoying so I put the original software back... Also I found the motor to be less...

    Did some of you install a chainguard with this motor ? (Especially with an internal gear hub). Any recommendations or warnings on compatibility ? I'm about to order one of those : https://www.bike-components.de/en/Hebie/Chainglider-350-Full-Chain-Protection-Front-p29665/ Thanks

    I understand what you mean now. I have the same feeling also when I start moving. Not sure if it's normal though.

    That's normal. The motor needs to calibrate at start, if there's a pressure on the pedal the calibration will be wrong and you get a weird behavior of the motor. Just to understand it, try to push strongly either forward or backward at start during calibration, and try to ride (on a safe...

    I think your motor just got too hot. I had the same issue on a long ride during a hot afternoon, it delivered much less power. I just let it rest overnight and it worked properly again. You should alternate the modes based on the needs, when you stay always on boost for a long time it will get...

    There are 2 different versions. You can buy the coaster brake version it should be stated by your seller.

    New "TSDZ2 Torque Sensor Central Motor"

    Not only for children or cruising bikes. It's quite popular in Germany and the Netherlands on city bikes, and nowdays they all have front and rear rim brakes in addition to the coaster brake. After some practice you can coordinate foot and hand brake and mostly anticipate much sooner situations...

    New "TSDZ2 Torque Sensor Central Motor"

    I have the coaster brake version with 350w. To me it has enough power, I can reach 40kmh on flat or go uphill at 20/25kmh (for a few minutes as it can easily overheat if you want to use high gears to go faster on a hill). The advantage with this version is that you can save your rim brake pads...

    New "TSDZ2 Torque Sensor Central Motor"

    Anyone in Europe selling an St link with the cable already soldered ? Or if not selling, lending it for a fee and I'll use it basically just one day to put the original firmware back to my motor as the wrong one is currently on it. (Non coaster brake) Naturally I'll pay the post costs as well...

    New "TSDZ2 Torque Sensor Central Motor"

    Same here. In a couple of months with this motor and the forum I feel I became a professional bicycle mechanic :) and bought the right tools as I learn. Torque wrench is definitely needed, especially that our bikes can go really fast, better not to over/under tighten something, as at 40km/h when...

    New "TSDZ2 Torque Sensor Central Motor"

    Thanks for the link, I'll probably try it. This one is more "liquid" and therefore better for the plastic? Another seller sells a smaller amount for 17€. I have a spare blue and metal gear so I won't change it for the moment, once i feel there's a problem I'll swap the gear and try this grease...

    I used this bearing grease not only for the blue gear but all the gears : Nigrin 74145 Mehrzweckfett, Tube 250 ml https://www.amazon.de/dp/B001BAU3VY/ref=cm_sw_r_cp_apa_i_DeKUCbVW89SX8

    Thanks for the feedback. I'll just change the blue gear soon and hopefully it will improve.

    New "TSDZ2 Torque Sensor Central Motor"

    Thanks for sharing the experience. Where did you find the coaster brake official firmware ? I'm desperately looking for it. You installed it with the same procedure as the open source firmware? I have a coaster brake motor with the wrong firmware installed (mistake by seller after I sent it for...

    Here you go : https://youtu.be/RlMZTA36elQ Put the 25kmh limit on off and increase speed limit (SD step). Be careful as it's illegal in the EU. I don't know how is the police dealing with ebikes in Greece but better to not drive too fast in busy areas.

    New "TSDZ2 Torque Sensor Central Motor"

    Hello, Which bearing was it precisely? Did you solve it by replacing the bearing only? I have the same issue you describe (normal motor whining sound and the gear sound on top of it). I sent it to Italy for repair.(seller pswpower) It came back with the same noise they didn't do anything...

    New "TSDZ2 Torque Sensor Central Motor"

    I had the same problem. I had to move the magnet/sensor many times before I could find the right position. Basically make sure the magnet is aligned on the arrow of the sensor, and try to move it until you get the right speed when walking with the bike it should show something 4kmh. Once done...

    Has anyone try to use the coaster brake version on a freewheel bike ? I'm planning to buy a hybrid bike with regular derailleur, a Btwin Riverside 120,when my motor is back from repair center. The chain would move backwards ocasionally but that wouldn't be a problem right ? Otherwise is there...

    Is anyone getting some regular creaking noise from the axle while pushing the pedals hard ? Going up hill or just accelerating on flat roads same noise... I have regreased and tightened all the elements that hold in place the motor on the frame to eliminate this possibility, so it looks like...

    A few Tongsheng TSDZ2 questions

    I have this motor for 2 months and 650km so far and still with the blue gear. I would say for commuting to work it's reliable if you put it on a solid frame, and make sure you take your time when you mount it so that it's perfectly greased (crank arms to axle + pedals and the contacts with the...

    Hard to say just like that. But I have the exact same setup, 38-19, and the 42 teeth fits nicely, still far from my frame, and the chain line is straight. I'll try to double check the side of my frame to see if it's similar to yours. Which version of the motor did you order ?

    So that's the noise after 150km assist level 4 on a small hill : https://youtu.be/qsiHfjyiVaE Sounds like a scooter, horrible.... Would this be sufficient to send it back under warranty or at least get the metal gear instead of blue nylon? (Retailer is pswpower) I can't open it as it will...
