Will a tsdz2 work with a 83mm bottom bracket? Looked everywhere without finding an answer
no, but i think this could be a path to follow:

Does anyone make an offset chainring with higher tooth count, ideally 52t?

(pictured chainring is 42t)

could this maybe also be solved with some spacers?

so how can i power it up? Connecting to a battery, see here the wires (just like LCD3): https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/wiki/Wire-KT-LCD3-to-TSDZ2 I added to the table at the end of page the 850C wires. 20181212_005527.jpg :thumb: :wink: it will get a beautiful coverglass an...

sorry for not being serious and doing childish stuff. but you wanted to know although i had said i did not want to talk about it.... :lol: I was worried that It could happen when opening the LCD, as users will have to open it to program.

Re: New "TSDZ2 Torque Sensor Central Motor"

so my question: can the device still be working or is it impossible? if anyone knows enough about this kind of coil... I think it may keep working but you need to try. Try to power on the LCD while it still has the original firmware and see if it works. I think that coild is part of the power circu...

Re: New "TSDZ2 Torque Sensor Central Motor"

Bumping this. Is that chain line bad news? Is the resistance normal? Is this chain line too extreme? https://imgur.com/a/NV6ny3Z That's the stock TSDZ2 42T. I was planning on replacing it with a narrow-wide, but since the stock ring looks a bit dished inboard, the line would be even worse with a re...

Just an update on the 750C. As you know this display is the same architecture as the 850C but with horizontal orientation and better buttons. It also has 4 buttons instead of 3 but is lacking the USB port of the 850C. I just wanted update you that the Bluetooth version of this display is now shippi...

2 things: video cannot be seen "video not available" the 850 video works
and: is NRST same as RST?
Yes, NRST = RST.

Maybe of Interest for some people: what is the plan: keep lcd3 alive like 850c or will updates not follow once 850 is released

how do you reset the trip meter?

I don't really know how that works, maybe it is like a matrix like used for keypads... anyway, it depends on hardware and so we are limited for the 850C hardware.

On current code, 1.1 and 1.2 are implemented but 1.2 ODOMETER is not. What I wanted to do but I didn't had time, was to store on EEPROM the last selected 1.x, so if user prefers to see for instance 1.1 DISTANCE SINCE POWER ON, the system will always start at 1.1 when users cycles over odometer fiel...

Exactly Andy.. I like 14s but 14s2p is not enough and 14s3p would be way too heavy unless there are some better cells out there than the GA's ? 15s2p is tempting but will it blow the display ? And can you get a 15s bms to suit ? It really depends if you want a heavy commuter or playful jump bike.. ...

My reason for buying a 36v with 36v battery was to minimise weight. Great piece of info for my decision making process :) Thanks a lot, indeed weight matters!
