Re: New "TSDZ2 Torque Sensor Central Motor"

What about the Shimano step e6000 cranks? Are they staggered offsets? https://www.pedelecforum.de/forum/index.php?media/vergleich-kurbelarme.8940/full&d=1524478604 I tried the Steps cranks once as they came in 175mm, they are curved a bit less than the Tongsheng (-8mm), the Bafang is -16mm. I prefe...

As far as I remember, the PAS magnets are in the outer ring of the secondary coil
You are right. There are another 20 tiny magnets .

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I don't know what you have in mind with a PAS Sensor. There's quite a few software bugs you can patch instead. The display cuts off after rolling a couple minutes without assist, the LVC and OVC need to be made adjustable to make the unit work on a 11S battery, and a soft start ramp would be nice to...

There's only tiny magnets next to the hall sensor that enables torque sensing.

Wouldn't spend much time in searching for a PAS.

Re: TSDZ2 and full suspension ebike

Hi @arty, the mid drive rotates towards your downtube. That's anticlockwise seen from chainwheel side
So just place some rubber onto the contact area and that's all.

Re: New "TSDZ2 Torque Sensor Central Motor"

Let me ask you this though.. a big qualm i had with the Bafang bbs02 was that it put the pedal position out on one leg by 10mm.. is there any offset in the pedals of this drive? Yes, there's remarkable offset. But you can compensate it with a single right Bafang BBS crankarm. It reduces rhe Q-fakto...

Re: bbs01 36v 500w stator

The rotor of the 500W (BBS02) is ~5mm larger than the 250/350W (BBS01). So the stator will be larger too.
That's the main reason for the weight difference between bbs01 and 02.

Did you fry the windings?
Then I would go for a bare motor.
You could sell the used drive unit in parts to cover some of your expenses.

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi Andy,
this is a known problem.
Get yourself a right crankarm from Bafang BSxx, then your pedals are symmetrical again.
You can order from greenbikekit or aliexpress, this stuff is unexpensive.

Re: New "TSDZ2 Torque Sensor Central Motor"

The chainwheel is attached to the main gear, right? So the main gear may be driven by both, the motor and the rider, right? The motor turns the small pinion to move the maingear, that's why there are so many teeth on it! And the rider rotates the crankshaft, it engages at the crappy bearing inside t...

Re: New "TSDZ2 Torque Sensor Central Motor"

Coaster brake version you can't backpedal. In terms of reliability there hasn't been too much improvement. The one-way bearing of the main gear is still a CSK 30 P, rated 110Nm, that equals a person weighing in 65Kg standing at the edge of a 170mm crankarm, usually a pedal. That's made to fail. Ther...

If you want ro disable the speed limit, just set "magnetic" at the end of the menu at 2 or 10 or whatever fits your needs.

This Tongsheng TSDZ2 is another retrofit kit. As you are from Denmark, maybe you're looking for an EU- legal drive. This one has 250W or 350W and torque sensing, similar to the Bosch Drive Unit. It's quite cheap and spare parts are widely available at pswpower.com I've got 3400Km on mine already wit...
