So, it seems, my problem was solved by neoprene cover for battery and charging at room temp.

I am sure, they didn't disconnect any cable, it was just some key combination. I recall, pushing "S" together with some other button / buttons. Don't know if from off state or already turned on.

Dear members, I would like to kindly ask you, if anybody can share shortcut how to reset Yamaha ebike error. I was pushing to hard my ebike and so chain jumped over a tooth, that's probably doesn't look like problem but controller recognized it as failure so immediately I was receiving Error 28...

Regarding speed limit, there is a cheap solution https://youtu.be/K8yF6mzg2aw I didn't try since I'm riding mostly XC and don't feel need to ride faster but for road it could be definitely first approach I would try. I looked at battery, because warranty said 1 year or 700 cycles and still...

Now I am not sure. Yamaha battery is 500g heavier and warranty cycles are 700, two times more than Bosch. There actually could be 10s5p configuration as 10 cells with 50g are 500g over. Then it could really make a sense to buff it with 3500mAh cells. But I still worrying about warranty, I...

Thanks silent, it's great idea to have another battery in parallel but I ride XC. I am using Economy mode and I can tell, I usually support 50W, rest coming from motor. It's pretty enough after 38t / 42t upgrade. Yeah, I think to upgrade cells with more capacitive, 3500mAh or more. I will...

yes, that would help as i wrote, i don't need much current, just to increase capacity I've understood, speak about assistance below 5Wh/km is nonsense.

Thank you Nobuo, Can you please confirm my previous guesswork? Are there really 10s4p 2900mah Li ion cells? I'm using only Economy mode, so my current requirements are only up to 8 Amps. I additionally geared previous configuration with 42t rear sprocke, so 38t front and 42t rear within 29"...

Hello, Did anybody disassemble original Yamaha battery? There are three connectors coming from battery, when fully charged 0V, 40V and 42V. Seems they are using 10s4p 2900 Li ion cells. Could be possible to replace them? Thanks. Edit...

Hello, Does anybody knows where to buy spare plastic cover of gearbox? Thanks

Issue with FS frame, my frame is Lapierre Tecnic FS900, I had to grind a bit from motor aluminum gearbox.

Actual controller settings

Ah, yes, you are right, motor will measure itself. So only way, without modifying bottom bracket, is installing pedal torque sensors? Or could be there another way? Thanks

Hello, Does anybody have experience with TMM4 torque sensor or similar? http://www.idbike.com/index.php/sensors It could be challenge to use it with Bafang BBS instead of throttle. Thanks.

You would check rear right arm of bike frame if doesn't influence kit too much. Some people are using washers to keep clearance but then kit is shifted to right side and chainline is poor. I had to grind a bit from motor aluminum gearbox to don't use washers and have proper chainline. I have...
