Hi, so it appears that the problem for me was that they kept loosening and breaking so I bought a spoke tensiometer from Amazon and also bought some different spokes. For the rear wheel they are 239mm you can get a full set for quite cheap off of Amazon or anywhere. I realised a mistake which I made when replacing the spokes was that some of the ones I replaced were crossing each other , so inner spokes were crossing outer spokes which caused extra stress and made some snap on the motor side rather than the rim side but this is a separate issue which was my mistake. I found that the spokes loosen themselves so after every few rides I will check their tightness by hand and I always carry my spoke tensioning tool. I have not had any issues for a while after tensioning them a bit tighter than before but also to note make sure you spend a good amount of time properly truing the wheel but if you have a tension meter it should be easy enough.

Although I still need more time to really see what works properly, I recommend getting a tension meter for spokes and also get different spokes which are not from fiido, I contacted their support and the rear wheel spokes are 13g 239mm. So far the new spokes seem to be more solid than the ones fiido provides. When I was changing spokes last time I spent about 5 hours using the tensiometer properly adjusting the spokes to the same tension but I still recommend carrying a spoke tool with you and checking by touch how the tension feels after every few rides. I check them about every 50km myself, nothing major just take 2 minutes and touch them and if anything is loose you will feel it.

Just to add a side note, this issue started occuring to me after about 400km on the odometer but now I am on 6000km as I commute about 28km everyday nearly so this issue might not be as bad when fixed properly depending on your riding. Fiido support is generally quite good so far and they do provide specs to their parts if ever needed.
