Re: E-S LMX 64 Bike Owners

I’m assuming it’s coming from the rollers, the chain is changing angles a couple of times, is this necessary ? Perhaps just install a derailleur on the back and remove the rollers ?

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

Nice so it LVC is reached then power keeps dropping to ensure LVC is not violated again ?

I assume that eventually the power cannot be dropped any more and the motor will turn off ?

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

Hot weather coming here so will be taking some pointers soon thanks for sharing. Btw I tried v0.20 b1 today. Commuting to work 17km each way. Firstly it was a very easy upgrade and setup from v0.16, I experienced no issues and the wiki was easy to follow. I tried all modes but found emtb and torque ...

Are you sure that the bin files does not work? At least they work for me. Nah the windows software STVP does not see bin files, only Hex files. Im sure they work just fine in Linux. Normally I would copy out the main.ihx file from the src folder and rename it to .hex however that wasnt there either...

Guys really getting excited about version 20, still on 16 and happy except for the known problem when you try to peddle harder the power reduces and the moment you back off a little it goes up again. Sounds like this is a maths issue and has been solved (I'm guessing??) My question to Buba is whethe...

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

It is not practical for users to pull apart their torque sensors although for the few that did it has really given us some good data. Just stating what everyone else is probably thinking by now... It should be fairly easy to set up a menu item to measure adc values for 5kg, 10kg, say up to 40kg whic...

Hi Buba, just wondering whether its possible to do any logging. I know its been mentioned before but Im sure it can be done easily just not sure about the best interface. The ulitmate would be logging to your phone via bluetooth.. eg. Cadence, human power, motor power, speed, etc If it were on your ...

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

Here is an article on the new 2020 BoschCX motor Just out of interest we have been talking about eMTB mode and I have been talking about reducing drag from the motor in case where you have a really low assist or max speed limit and you are trying to peddle faster than the motor. Not really many take...

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

Yes I think Wayne also mentioned EXPO as you have shown on the graphs above..

The user could set levels 1 to 5 as normal for their riding style and eMTB mode could be level 6 which interpolates between levels 2 and 5 in an exponential curve.

This should be easy to implement.

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

I have the Trek Powerfly with Bosch eMTB mode. I always use it by default. For off road mountain biking it is so good I never have to change modes. It will help me when I go up steep hills and back off when I am just cruising. It seems to work out how much assist to give by what speed and how much p...

Re: E-S LMX 64 Bike Owners

Is it possible to move the red rollers further apart so that the angle of the chain is reduced. This may help ?

Possibly even using 2 off toothed chain tensioners instead of hard rollers..

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

what exactly is high cadence mode changing technically? I use a 48V motor, switched it on, but I do not feel much difference. How does it work? Does it affect the efficiency ? Why does the menu warn this might harm the motor ? Why does the menu state the mode might not have any effect on 48V motors...

Re: Right side crank play and/or slipping problem

Replacement comes in form of main gear and bearing already fitted. According to the info I gathered, after the blue gear failure, this is second ...

Re: New "TSDZ2 Torque Sensor Central Motor"

If you are looking at spending $3K then you wouldn't use a TSDZ2 motor. Go for one of the Giant bikes. Someone at my work bought one for $2800 + $250 for a chip and he does 50km/hr. I don't agree with him speeding but just saying you will be getting an awesome bike built for purpose with a motor tha...
