    Winther Kangaroo Luxe TSDZ2 build

    Judging from the images, you may have problems with that frame. I had installed it on the Dahon Briza, that is somewhat similar to your bike (but with some significant differences). I had to cut some parts of the frame (luckily, those were parts of the overhangs so it did not affect the...

    Tongsheng TSDZ2 pinion gear cover friction

    You have to fix the root of the problem first - and that is the infamous "wobbliness" issue on TSDZ2. Buy some quality bearings and follow the instructions on this forum. And do it before it destroy your torque sensor coils.

    New "TSDZ2 Torque Sensor Central Motor"

    I believe that administrator should lock this topic. There are like 15 or 20 paralel discussions fighting for the same space, absolutely impossible to follow. Why is it so difficult to start the new topic when you have something different to discuss?

    TSDZ2 750W no more powerful than 250W

    I did all that (after the torque sensor failed), and it seems to work fine now. Didn't want to elaborate too much here, as it was already explained in details in another thread.

    TSDZ2 750W no more powerful than 250W

    I have the same experience - first I installed 48V 750W version on my bike, and a year later a 36V 350W version on my wife's bike. Power-wise, those both feel about the same. Being said that, i think that power is adequate on both bikes - I have some pretty steep hils around my house, and i can...

    TSDZ2 crank position relative to the torque sensor

    I don’t think it makes any difference - your feet will create variable torque depending on the force and crank position, and the torque sensor will measure it regardless of the current orientation. Also it is not possible to see the position of the torque sensor without taking everything apart...

    TSDZ2 repair - need advice

    I must admit that I don't really understand this design. As far as I can see, coils are paralel to each other, and that basically makes a transformer. Since the winding is in the direction of the rotation, it doesn't matter if the axle is rotating or not - it should work just the same. But the...

    TSDZ2 repair - need advice

    Replacement come without springs, I had to reuse my old ones.

    TSDZ2 repair - need advice

    Yes, it is the same like yours. If they changed the design, at least they should provide some assembly instructions. Besides, I beleve that those nipples are there to take the pressure from the cable entry point. Anyway, it is too late now, it is glued by epoxy glue and I am not going to open it...

    TSDZ2 repair - need advice

    No, i did not find any traces of retaining compound. Also i got only one teflon disk originaly (replacement torque sensor came without it). And one of 3 nipples on the coil was missing, so i used one from the old coil and glued it in place with epoxy. All in all, pretty sloppy job. Anyway, I...

    TSDZ2 repair - need advice

    Thanks! Initially I had a pretty bad case of wobbliness, after less than 500 km's from new. At the time, It already started to eat into the plastic cover. I thought that the culprit was the sprag clutch, but it turned out it is not the case. Anyway, i put 5 small washers between the big gear...

    TSDZ2 repair - need advice

    Hi! I manage to destroy my torque sensor, so I ordered a new one (had to wait for more than 10 weeks for the damn thing to arrive). I have 2 questions: - Static coil is spring loaded, consequently it is rubbing against the rotating coil (the force is not that big, but still...). Shall I put some...

    Tsdz2 design flaw

    This is an update: Few days ago I noticed new sprag clutch behavior: it seemd to be stuck in the "lock" position, acting as a solid unit. So the wobblines dissapeared and my TSDZ2 suddenly became the "coast brake version" of the motor. It did not have any adverse effect on the bike usability...

    Hardware temperature control tsdz2

    Yes, I cut one strip of 10 mm thick thermo pad (100 x 30 x 10 mm), stretched it around the stator and put the cover in place. I tested it only once, climbed on one hill (altitude difference about 160 m). ambient temperature was about 15 degrees Celsius. Temperature climbed from 15 to about 30...

    Tsdz2 design flaw

    Hi! Having nothing to do in this days of self-isolation, I decided to make a spring service on my TSDZ2 bike that I assembled last year. So I realized that there is about 2 mm play in my front sprocket, way too wobbly for my taste and with only 500 km under my wheels Removing the front...

    Hardware temperature control tsdz2

    Hi! I added a termometer (for a bit of "steam-punk" flair, i put the classic capillary thermometer, without a single electronic component :-) I put the thermometer probe in the cavity behind the plastic cover and added some thermo pad to keep the pressure agains the housing. Not directly on...

    Hardware temperature control tsdz2

    I put 10 mm thick pad on the same position, on The Dahon that I am building for my wife. I cut one strip of 10 mm thick metrial (100 x 300 mm), found out that when you strech it and wrap around the stator, it behaves like a mixture of clay and rubber, so It shrinks back with a bit of delay, just...

    Dahon Briza D8 and TSDZ2

    Hi! I am looking for the e-bike solution for my better half and here are her requirements - Small, but not too small (mostly paved roads but also some dirt and gravel paths, so 20" is not optimal) Low step through frame, foldable, lightweight, torque sensing is a must I could not find any...

    New "TSDZ2 Torque Sensor Central Motor"

    Regarding the crank offset, I was also looking at it, found in my garage one old left crank with zero offset. Then I discussed it with the bike mechanic, he told me that he can convert it to the right crank (basically drill out the left thread and put a new bushing with the right threading)...

    Easy Pedling on electric Bicycle (Geared or Gearless)

    It is difficult to objectively estimate the drag from the motor or even the clutch because human body is constantly adapting to new conditions. I call it the "electric legs" syndrom. When I started riding my TSDZ2 kit bike, I felt that there was no significant drag in the drivetrain. About a...

    New "TSDZ2 Torque Sensor Central Motor"

    I would be careful with that - recently there was a post from one user with the similar situation, he also just let the motor rest against the downtube, and the result was that the whole casing cracked and split in half - and it wasn't pretty. The downtube was kind'a square, he did not use any...

    TSDZ2 Sprag clutch

    Hi! I have my TS about 2,5 months now and only about 360 km on the clock. It is running fine, but I noticed about 1mm play on the chainring already, and also some play on the crank. So it seems like it is time for new sprag clutch order... I can order new "Big Gear" from PswPower, but it will...

    How to plan how much battery I need for a TSDZ2?

    Hi! I have TSDZ2 48V / 750W. From your parameters (1500m 8-9% incline), your home is about 120 - 135 m above the city level. I have similar situation, although somewhat lower (about 60 m above the city level). And I am a bit heavier than you. I have a LG brand 48V battery in 13s4p configuration...

    New "TSDZ2 Torque Sensor Central Motor"

    Hi! Newbie alert :D I also put a 750W TSDZ2 on my city bike and so far I am quite happy with it. For now I am using the standard firmware, maybe I will update it during the winter pause. I found on the web that quite a few people are complaining that it is not powerful enough and that 8Fun...
