Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Did you read my whole post and other's? Opening SOC sub menu leads to a crash. And still i don't see what needs to be setup to avoid my problem. I can set Wh used and reset voltage. And those values have been set before. So the only thing i can imagine (as it's not described elsewhere) is that you n...

I know how hard it is to write a manual/wiki, but the TSDZ2 wiki has information spread all over the place. To find what you are looking for, you can: - read the Table of Content...

Since I upgraded to 1.0 there are "slight" differences between what my BMS knows about SOC and what 850C THINKS about the battery. I don't know where this comes from. I haven't found anything about battery calibration. You need to do your work and read the configurations page. I would hav...

People say you must have brake sensors, personally I think it's fine to just hold the bike on the brakes and rest a little pressure on the pedal*, no different to a hill start in a manual transmission car. You soon get used to the behaviour. I'll go on record and say I don't have brake sensors inst...

Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Assist without pedal rotation works, kind of. But it is buggy. And it also seems to give a variable amount of startup assistance depending on the assist level you are in. Which I guess is to be expected... For me, it seems to take some time after the pedals have stopped before it becomes active aga...

And it seems I can't make the motor engage at zero speed. It is even "worse" - the motor needs at least 60W human power to even engage - but human power only goes up during pedaling. What do i oversee? Yes, motor startup without pedaling a bit (make motor rotate, easy motor startup form 0...

Re: New "TSDZ2 Torque Sensor Central Motor"

romelec was so nice to make the CAD of the axle. Some questions still remain. Is there someone with a broken one and can make some more pictures? Ideally together with the attached torque sensor?
Or maybe even send the broken one to me? I'd pay for p&p, so we can maybe make a stronger axle on day.

Does the axle need to be heat treated? Another thing that you might want to consider is make the crank connection to accommodate the spline style cranks.
I wouldn't heat treat it. Also depends on the steel used. But some CroMo steel should be capable enough. Better let it bend than break...

I've created the pedal axle in Fusion 360, you can view/download it here: https://a360.co/3gwHR9I The dimensions should be pretty good but an error is always possible. Thanks for modelling the axle. So I can have look at it without having it in hands :) :thumb: Overall it should be fairly easy to m...

Shame. Didn't look at the screw it self. Not that I could have read it without magnifying glasses anyway. ;) Thanks! I'm not using the supplied cranks, as I had to shorten mine because of the 20" rims I use in my former 26" bike. Could be that the Tongsheng taper is not exactly the same as...

Re: New "TSDZ2 Torque Sensor Central Motor"

That's why I asked for the correct torque the first time, but haven't received an answer yet. I can't find a number. Of course a proper built axle can be used with proper screws as well without risking stripping the gears. It may be that my internal threads are already somehow damaged, which leads t...

Re: what's that sound?

In addition, remember to grease the Spindle and crank. This allows them to slide easily to increase the pressure on the taper while reducing the load on the bolt and the threads. Thanks. I didn't grease them. Good point. I think I remember someone mentioned to heat the crank up with a propane flame...

Re: what's that sound?

Better bolts should be readily available at any decent harware or bike shop. They come in different strength ratings. 10.9 is a good metric rating. 8.8 is common, and unmarked bolts are crap. If the internal threads are damaged, a bike shop or auto mechanic should be able to drill out the damaged t...

Re: New "TSDZ2 Torque Sensor Central Motor"

The hardest thing to duplicate would be the splines, but they are short, few in number and stand proud of the shaft itself so should be less difficult than they might be. IMO, just controlling the seat diameters so the result is closer to a press fit would suffice for many people. I now checked the...

Re: New "TSDZ2 Torque Sensor Central Motor"

As posted above, you can buy the axle alone from eco-bike. Only makes sense when you're based in the US. P&p double the price for shipping to Europe. And you still get the same junk as was installed originally. Same issues. I once had an axle of a MAC hub motor break (it has this large axle bore...

Everything in the motor looks fine. All gears look intact, bearings are ok - Chinese style, and I can't find any obvious problem.

Unfortunately sometimes yes. And NO, it's not good, but there are solutions to help minimize the wobble.
But this thread is for the FIRMWARE only. There is another thread about HARDWARE.
