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

    It seems you got the full options version :)). My bike is Mtb 14kg+ with no motor. I use city tires Schwalbe Energizer+ 47-622 on my 29er. I use 48v battery in 48v motor with standard 42 chain ring and high cadence mode. So ratio 42 X 11. How much power are you getting from the motor at 45kph...

    Hi Buba, It is good to see that all is well with you! Can you please add some details how are you getting to this speed easy? What assistance level and what particular settings are you using? I can hit 40 kph with medium effort and over 45 kph with significant effort. I am using also exp...

    The problem was due to power cable being crushed. Thanks for support!

    I have a similar problem with Adam. When I press walk assist the display shows 100W but the motor does not move. I also took it out. Without power I can move motor head easy. With power it is fix! Torque sensor diag works ok, also cadence and speed measurement. Just the motor does not move! I...

    I did in last weekend a MTB track with 2000+m altitude level and 56km. I used 620 wh. Ride done with 0.20 beta1. On flat road and medium ascend, power mode works perfect. Good power and better torque. On difficult climb, Emtb mode is king! It has a lot of power and the motor reacts instantly...

    Forgot to mention that I got 15% battery saving :). I tested this on my way to work(28km) and I do this road dozen of times, I usualy use 30%, now I got 25%! :lowbatt:

    I did some test with 20beta1. SO far no issues at all. My test configuration is acceleration 80%, modified high cadence mode and torque sensor adjustment to 75. I mainly tested in city traffic power mode but also EMTB on a steep garage ramp from -2 to 0. Power mode seems indeed a bit more...

    New "TSDZ2 Torque Sensor Central Motor"

    From what I managed to check, the slack originates from the clutch bearing from main gear. But any feedback is welcome.

    Hi everyone, I am having some chain noise similar to the one when the shifter is not able to change the gears properly, just it comes from the motor area. I hear it when torque is applied to pedals. I think this is generated because the chain ring has some slack and it moves a bit. I added some...

    @casainho, thineight Thank you for quick help as always! I managed to crush the lcd cable between the frame and the motor :(. I was lucky it was not ruined so I managed to give it a bit of tape and all is ok... for now. The behaviour was very strange. I started to have burst of motor power and...

    Hello, I did a few flashes of the KT lcd3 and now it is almost brick. In the last 2 versions on boot all chars light up and after a few seconds it state working. Now it lights up all symbols and it is frozen. I did write 4 different versions and the result is the same. I had no crashes and I...

    Thanks for sharing a very effective and cheap solution! I used aluminium, but it is very hard to make a good contact with the exterior case.

    I did some tests today. I kept acceleration to 80 so I am not limited by it and adjusted the torque conversion param from 67 to 75. It seems that the torque range is extended. I managed on startup to get peak of 700w+ on level 3 assist. This is very good news because I feared i will have...

    I noticed same issue since version 0.15. With maximum assistance if you pushed very strong the power drops to 300-400w. With slow push and constant I got 850w. The only thing I did to overcome this was to use higher cadence with High cadence mode enabled. I managed to do difficult slopes with...

    Hardware temperature control tsdz2

    Nice solution, Andrea104! I made a similar one from aluminium. The complicated part is how to get good thermal contact with the exterior shield so you can draw the heat to the outside. How did you did that?

    Ok. I am almost sure I do not fully comprehend how the new configuration works. This is why I have issues. I have additional questions :) 1. Acceleration - I will surely make this 100%. Is it possible to put more, for example 150 if I want higher acceleration? 2. Assist without pedal rotation -...

    Did some more tests. I just installed the motor on a new MTB 29". I am testing A7 with the default assistance levels. I tested power mode because I wanted to see improvements form 0.19 first, at the moment only on flat city road. 1. Acceleration. Previously I used 8A/s and was very pleased. Now...

    I had SDCC 3.8 which was previously recomanded. Indeed the current LCD soft exeeds the current memory if compiled with 3.8 or lower. Very good idea to use 3.9 to save memory. I installed 3.9 stable and all works like a charm :). Indeed the power requires a long press to start. Sry I did not know...

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

    So now in order to start I need a long press power button similar for off? For 0.18.2 short press was enough. For the code I used this configuration since the beginning and worked fine for 0.18.2 included. Did you changed the compiler version since 0.19+? I am getting warns that there is...

    Hello, I see that EMTB is raising a lot of debate because different users have different needs. I think it is impossible to please everyone. Adding a menu just for configuring EMTB is not a good idea now due to memory limitation. An idea is to use the EMTB mode as an option used in conjunction...

    Hello everyone, I have been reading the last few pages and I can't wait to test the new sensor calibration. Thank you dev team for making this possible! I know that there is a memory issue with KT3 lcd and new features cannot be added, but the motor functionality features are the most important...
