I just bought a used flykly rear wheel and want to build a charger for it as it came without one. (I am an electronic engineer). I need to know the spec of the original charger and the wiring to the 6 way connector. The connector on the wheel is a 6 way female. I have found connector cables online described as 6 pin Jolet which look like they may fit. Can anyone confirm that ?
I have dismantled the wheel and there is a zehus circuit board inside and also 8 double cells, measuring about 25 volts in their current state of charge.
If anyone knows whether the Li-Ion charge circuitry is on this PCBA or is it in the external charger that would be good to know.
Thanks for any help.
How are you doing on your search? I have a wheel, charger, handlebar battery thingy and manual (attached).

The connector on the charger got broken but it is still functional, albeit, fragile. I tried to find a charger, even the connector on the charger, but had no luck.

Today, 7 oct 2022, I charged the wheel for the first time in years. The charger indicated that it charged (light went from red to green) but it charged within an hour. The manual indicates that one needs the app to configure the wheel. I suspect the default % assist is 0,. Without the app to set it, the wheel worse than useless

From you "local time" I see that you're probably in Europe and I'm in Pacific Time. Maybe there's a possibility we can help each othe.

I have had 2 of these wheels. Greatest invention.
I have seen the schematic somewhere. If not online, try reaching out to Zehus or the founder of FlyKly because they seem like nice people and I am guessing they will try to help you. My first wheel had the 6 pins and the one I have now does not.
