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

Help needed: I have installed the OpenSource firmware without problems on my TSDZ2 (0.19.0). But I didn‘t succeed to install the firmware on the 850C using the USB to UART cable method (anybody successful yet?) ... Any ideas? I have built a number of these 850c bootloaders over the last few years. ...

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

Is the BBSHD better at maintaining RPM and torque as the battery discharges? I had a BBS01b and while virtually silent, its biggest drawback (other than PAS) was the huge loss of torque / power at decent RPMs. In fact even with a fully charged battery the max RPM was limiting without "hot-rodding" ...

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

working with bafang engines is a good idea. But the bbshd is too powerful. There are transmission problems, the chains are broken, free wheels and hubs. Even the rear of most bicycles flexes with its power. I have been using a BBSHD for far longer than the TSDZ2 and what you say is quite frankly wr...

No more backwards resistance when braking for the Coaster Brake versions! :) Just tested, works great! Will add a couple more changes and features that should make the experience even better. For everyone!
That is awesome news. You guys truly rock!

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

With A3 on coaster brake we are noticing that if you go from pedaling to brake quickly, as in an urgent braking situation, then backward resistance is there. If you then release the brake and then reapply the backward resistance is gone. Alternatively, if you have time to pause/coast before applyin...

Alpha 3 is live! Indeed it is! We just installed v0.20.0 alpha 3 on a friends coaster brake handcycle and it works!!! This is truly a turning point for powered handcycles. After celebratory yells and high fives, I took this picture of Jeff with the handcycle we installed it on. It's his bike. . v0....

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

I actually bought the coaster brake motor when ordering the last time just for this reason. I also created the double cadence resolution on that motor just so it stops as fast as possible. It is especially easy to setup on that motor. I do not think that any commercial product in the world is using...

Re: New "TSDZ2 Torque Sensor Central Motor"

Good ldea. But can it work with a 68mm BB? Yes, it can work. I do this with 100mm BBSHD motors on 68mm BB tandem bikes. 68mm BBS02 motors will actually clear the spider on the left side. You will need to space it out with BB spacers to install the bracket. I have some 10mm spacers. PM me if you nee...

This is the new piece of code to turn on/off the motor PWM. See that if there is not ui8_m_adc_battery_target_current ...

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

I tested v19 beta 3 on a coaster brake motor. There is no backward resistance but I also have no power. I did a reset and triple checked all the settings. There are good torque and PAS/cadence readings but always 0 watts. Any ideas? The motor worked fine with v18.2 but had extreme backward resistan...
