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

Having the motor support only above 6km/h is just plain stupid. Where are you from? i hear this the first time. maybe you are confusing something with the 6km/h limit for motor support without pedaling? With pedaling, the limit is 25km/h in europe which is good enougt for most situations. Sorry. My...

nah, i would not help people to break laws. .... currently it is all below the radar but i would not like to see the open source ebike movment thrown into the same bucket as the illegal ebike tuners. I understand your motivation, but I also like the idea of own responsibility. Having the motor supp...

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

Rene Kreher (youtube link some posts ago) has asked his insurance and some german police office and got the feedback that they do not really care much about the rated wattage (as they cant measure it) and stick to the speed limit and only power while pedaling rules. Well, one, two, or even three po...

Hi, New to the forum and ebikes. I tried to find information if the 500w TSDZ2-motor with the 850C display can be restricted to a lower power level like 250w? In my country You will need a traffic license for motors over 250w. During my daily commutes more power probably won't be needed. You don't ...

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

Would you consider adding a configuration option to hide the clock altogether seeing how unreliable it can be and how much it can drift if you don’t use the bike every day? I’d personally much rather not see the clock at all than seeing it display the wrong time every time. +1. Makes sense. If it c...

Re: what's that sound?

Casainho, Do you have brake sensors instaled? Yes, I do have now. My very first time, I didn't and the blue gear wore just after 20 kms, after I did a few brakes with motor at max power settings of original firmware. The blue gear did damage to me only on that situation and after some times when my...

Re: New

Consider replacing the plastic with the brass gear, apparently not too noisy. And personally, I'd stick to a 13A ceiling, even 12A better. Or go to BBS02 (better than BBSHD?) I don't mind replacing the blue gear. There needs to be a "weakest link" that's easy replaceable. I just wouldn't ...

Also, you are using the OpenSource firmware so there should be no warranty anymore. Also, are you sure the 14 Amps second increase ramp is a safe value? Did you tested it for how long? I wouldn't have expected and warranty at all. Sending the motor to some other country, and waiting several weeks t...

Re: New

Stripping the gear would require abuse by definition. What's the max phase amps used? Unless they had a bad batch of Delrin or something. It's set to 16A battery @14s. Brake sensor & temp sensor installed, and never got over 80, but problem began at 50C already, so it shouldn't be a heat issue....

Had my maiden voyage today, first time riding more than a few meters in the driveway. All went fine, but after around 20min a strange sound started inside the motor.

Re: New "TSDZ2 Torque Sensor Central Motor"

Totally depends on your bike and weight. With a fatbike and bad gearing it sounds reasonable.
What's your cadence in highest gear? Normally, I'd say 40km/h needs around 1000W, and this kit is able to deliver 500W sustained and ~700W-800W (battery) peak.

I use a 16 tooth and a 23 tooth sprocket at the same time on any Alfine & Nexus hubs. Machined down and welded together with a derailleur. It allows me to have the best of both worlds, speed on the flats and downhill and great climbing ability on the uphill. https://youtu.be/G6kQvM4Or3U https:/...

Re: 90rpm cadence limit

I assume, and you wrote it, CPU seems limited with this controller, but I think field wakening is the only way to go to get support at higher cadence. 90 is a good rpm for long time pedaling, but as mentioned it can be much higher for shorter periods. The other advantage is, that you can gear the b...

Re: 90rpm cadence limit

I need to write about this. I consider the firmware is mostly finished by now and so it is a good time to write about all this. cadence 90 RPM = 512 motor ERPS / 4000 RPM (motor RPM nominal value) 1. the motor itself, should achieve the 512 motor ERPS (cadence 90 RPM) at 48V battery voltage but wit...

90rpm cadence limit

Could someone please give me the info about higher cadence software? I read it once but can't find it anymore. And what's the reason to stop motor power at 90rpm? That's too low for my finding. If you do a fast downhill you can pedal much faster, and same goes for very slow uphill in lowest gear. Is...

That happens also on may displays, maybe it is an issue on the firmware... That's good to know. If it's software I'm sure you will solve it.
