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

Today I spent an hour on the test of version 20, unfortunately alpha5 (I couldn't upgrade but I think it changes little) Obviously every test is conditioned by a thousand factors 1) I live in a hilly area, so only descents and climbs, no plains 2) I am old and fat :-(, 55 years old, 173 cm tall and ...

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

It's quite simple ... when I had the original software the engine gave little power. On the 20% gradient I could not have continuous 300w and it was a great effort. Obviously the temperature is much lower. Personally I want to have fun and an engine is cheap .... about 65 € I don't want automatic li...

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

Very excited to hear that and good to know what sensitivity level you are using! But also what you would prefer. I think it would be possible to improve the formula so eMTB is operating better and can fit your needs with only one assist mode. It should be great in any sensitivity level, that is the...

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

I noticed that the voltmeter in the 20 version marks 0.5 volts less. Is it a problem with my battery or has anything changed compared to previous versions?

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

I upgraded to the alpha 5 version without any problems. I noticed a better watt filter. I tried only the power mode version, all perfect! I reserve the right to make further comments when the room temperature drops a little, now we are close to 40 ° and riding a bicycle is a real pain. Thank you so ...

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

I tried the 20 alpha 4 version for a short time. As soon as it was loaded, neither the engine nor the walk assistant was going to work. After reviewing the settings 3 times, everything went well. Very strange. It seems to me to be slightly less powerful than version 19. Unfortunately the test was to...

I agree with casainho. user needs are too many and too different. the project must be simple and work well from the motor side.

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

Today he took a longer ride with some off-road vehicles. The following considerations concern power mode. I noticed that the feeling is of having slightly less power, but perhaps it is due to the greater progressiveness of the pedal. In previous versions it was more on-off now it is more sensitive t...

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

In fact in the 18 version and later in the 19 the start, without boost, is a bit weak, on my mtb it takes almost half a pedal stroke and takes a little time to reach the maximum power. I don't care because I have very short gearshifts. But I can compare with the brose of the turbo levo which is much...

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

my opinion is that a starting system based on too sensitive cadence is a risk. Just move the bike by touching the pedals and part forward. a quarter turn of delay is a security

Re: New "TSDZ2 Torque Sensor Central Motor"

However the dimensions of the motor shaft are ridiculous, you can see in the picture the comparison with a pen.

Re: New "TSDZ2 Torque Sensor Central Motor"

it's not a short circuit it's just too much heat. I have repeatedly seen the temperature sensor reach 105 degrees. I think it's a miracle if my engine is still able to turn. a short circuit does not burn the windings, the motor stops first. This is the reason that led me to radical changes shown in...

Re: New "TSDZ2 Torque Sensor Central Motor"

it may be an assembly mistake. I had the same problem with a 2017 engine but it was my fault. I wanted to grease the blue gear but the engine did not come out and either tapped lightly with the hammer. Unfortunately the engine shaft is not elastic but fragile and when I reassembled everything after ...
