I am afraid to destroy it doing so because if another drive-train will fail Kindernay is the only option I have (besides the oil leaks it just works). Also depending on the ratchet mechanism grease actually can make it stop working or make it works worst or can cause shearing and destroying the...

I poured full 40mL bottle before and my Kindernay VII leaked. While I am OK with oil leaks in general I am not OK when oil leaks on the brake rotor and this is what happened on my Kindernay VII. I rode it like that a year virtually without the real brake (once oil touched the brakes you have no...

Wattwagon is still a partner of Innotrace according to this page https://www.ebikerepair.eu/partnership/

Recently started digging deeper into the motor and found the rotor bearing (the one close to the gear) is completely locked and the inner race sled on the shaft. I disassembled the rotor and found the locked bearing rubbed into the shaft mating surface and damaged it. I am not sure if the...

It is indeed 20ml according to the manual https://api.kindernay.com/wp-content/uploads/2024/02/Kindernay-VII-Installation-Manual.pdf

This guy says it takes 20 ml of oil (even less that updated and reduced amount of 30 ml)

I made a cable for VESC Express. I do not know how those connectors on the VESC Express side are called (I do not remember where I found them) but the end on the Bafang connector side can be made out of these parts...

Cheap alternative to VESC Express dongle...

Alright, great news, I think I fixed it. Just soldered a new AD8418WBRMZ chip, and the shortage is gone. So it looks like it is going to work. Now I need to repair the motor shaft (the current one wobbles and can hit the rotary encoder again). I am planning to use the new 15 teeth rotor with new...

Found another shortage between 3.3v rail and ground. This time in the bottom board. I was thinking the rotary encoder board is bad and detached it but it turned out the phase "U" current sense amplifier AD8418WBRMZ has internal shortage between ground pin and 3.3v Vs pin. Placed order on new...

If anyone has Innotrace X1 controller laying on the table and willing to try to grab firmware and share it with me is how you can do it (I guess it will work only if the STM32 chip does not set in protection mode though. If it is in protection mode I think this way is not going to work. But...

Hello Krasnodar. I need compiled firmware .bin file to repair my Innotrace X1 controller (please see the post above). I am not sure if you saw my email. Can you please send me a compiled binary file (.bin) for my Innotrace X1 controller adjusted for 3000W motor (52V 60A, 14S lithium battery with...

Hello Dedo. Can VESC tool extract .bin fie firmware from the controller? The original STM32 chip on my Innotrace X1 controller is dead (internally shortened 3.3v and ground pins). I guess the FET driver failure destroyed the chip. I soldered new FET driver and STM32 chips and I need binary...

I think my Kindernay VII sounds as loud as yours when it is freewheeling in the air and it feels quite when I ride it.

It does sound noisier than mine or maybe this is just microphone pics the sound this way. Mine is leaking.

Where I can purchase one?

I am looking for the most puncture resistant tire in size 27.5x3.00. I do not care if it is going to be rigid as hell, or heavy as tank (I got 3000W motor so weight is not an issue for me), I also do not care about the threat style, color, bead material etc. All I need is the toughest (and maybe...

Wow, that's not even close to what they draw in the advertisement

The gearhub still works the same.
