Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

Does it seem like you'll always have to physically open it for the first flash? I've cracked the LCD on my KT-LCD3, and I'm trying to decide whether to buy another, or an SW102 (a form-factor I would prefer), or both. From the noises here, something that works isn't far off (it'll take a couple of w...

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

I clear remember some users saying that they use the Startup Boost feature, but maybe they are now riding instead of being here following this thread and giving feedback. I'm one user who said I liked boost, but only because I thought it made the system seem more responsive. My preference would be ...

I am so sorry if the community feels the development is taking too long.
Personally, not at all!

I'm impressed at how much you've done hard on the heels of 0.19.0. Way more rapid than I'd expect. I'm only itching to try it because it sounds so good.

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

Quick update for anyone interested. I am very satisfied with how everything is working but have a couple of things to do. Am now focusing on the cadence sensor. Sweet! I'm just about to go on vacation, and very enthusiastic about trying all the new stuff some time after I get back in August. Thank ...

Re: TSDZ2, how do I know I'm not wearing out the motor?

I recently installed a 52v 750w TSDZ2 motor on my road bike. I know that riding in too high a gear will eventually wear the motor out. However, how do I know this is happening? In other vehicles, you can tell if it is overworked. You can hear a car's engine struggling, or automatic transmissions sh...

Re: TSDZ2 and belt drive?

I am used to riding a normal bike and do enjoy pedaling. The reason why I'm looking into an e-bike conversion is because my geeky side thinks it's pretty cool and because the hills are brutal where I live. I would also like to be able to ride 30-50 km easily. Basically, I want a bicycle that helps ...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi all, I read in this thread that the motor shuts down when cadence exceeds 90rpms. Yet I am almost sure I have pedalled faster than that and the motor was still helping me. I am using the stock firmware. is the 90rpm limit a "feature" of the custom firmware?the I will test again, but in the meant...

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

I have added so many functions and optimized so much space it is insane. But there is a limit. Trying to make the firmware react so good that we do not need Startup Boost and get some space back. I definitely think Boost seems like a band-aid that can be discarded if you improve the responsiveness....

Re: Assist problem on the TSDZ2

I haven't done this (new owner myself) but I know both the blue nylon drive gear can get stripped, and the sprag clutch (that acts like a freewheel) is also is known to fail. They're both fairly easily replaced, I believe. But I think (?) if it's the clutch, then your pedals are what would slip, and...

Re: New "TSDZ2 Torque Sensor Central Motor"

For now I am using the standard firmware, maybe I will update it during the winter pause. I'm a newbie too, but I think the FOSS firmware is well worth it. I didn't spend a lot of time with the stock firmware, but I still feel like the FOSS is more responsive, and way more flexible. Also, I've seen...

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

The experimental high cadence setting (48V motor) works just as well as I'd hoped, and I no longer have it die under me just before I want to change gear. While I was exploring all the config options I enabled Boost, with default params, and I like it. I'd vote for having that enabled by default; it...

What is the best way to connect 3 wire brake sensors (through cable type) to the KT LCD3 cable- display?

Maby speed sensor is too near hub, try to move it and speed sensor and magnet gap is important too.
I should definitely experiment with that, but can that be a problem even if I'm seeing good speed readings? AFAICT I always see an appropriate speed.
