Bike impossible to ride due to resistence

[Victor Emanuel]

Here is a clip with what happens: https://goo.gl/photos/LdJuEaTpaWuNNmmcA and here the problem is more evident: https://goo.gl/photos/v7oghbQxYuruxZfbA This is happening almost every time, when I ride.

BUT on Console everything is ok . I am sure there is an issue with the engine. Cables are fine. I restarted everything. When I disconnect the battery / console everything w
orks ok. The problem is only when on battery.
If I use maximum level of assistance it is a real battle between the acceleration and resistance . You can hear the noise..
Any help please what should I do? It is very hard to find a dealer where I live.

Victor- Is your derailleur bent out of shape? In your video it looks and sounds like it's hitting the spokes.

Agree with BobG. the derailer is hitting the spokes, surprised that you can't see the wear on the spokes.

Should the chain be on the other side of the metal tab? Make sure the chain isn't rubbing on this tab.

Hello, Thank you all. No, there is a problem with the engine pins, as I heard. I need to send it to a service, but is expensive for me.
