Torque arm

I own an Ecotric Hammer and am having an issue with the rear axle spinning under load which in turn is pulling the power cable apart. I thhink I need a torque arm to resolve this issue but am not sure where to get them for my bike. Please let me know where to get these for my bike and or another solution to stop the axle from turning under load.
Thank you in advance for you

did you ever solve the problem as i have the same issue even a torque arm would not solve it it even snapped some wires and i had to rewire it,the bike id brand new never used
 
On any motor with axle flats: Once you spin an axle its over. There is no recovery as the dropouts have spread and the frame or fork is literally ruined. Cannot be fixed. Even if you bash the dropouts back together so they are parallel again. Damage is done and they are compromised. The thing to do is use torque arms in advance of this happening.

Not once it has already gone bad. Unless you are talking something so substantial it takes the place of frame dropouts, like the Dilinger arms that are essentially another chainstay. With spread dropouts, you can't bend them back and expect them to hold a second time, even reinforced and even if you can bend them back (i.e. chromoly and heat and a whole lot of sweat and swear words). realistically you'd have to cut them off and braze on new ones, hence my 'frame is ruined' conclusion, since so few people can do that economically. I'm not counting someone with brazing equipment who can fabricate entirely new parts, or who will weld on new plates to replace dropouts, sub in longer axles etc.

Unlike my commie nemesis, I am willing to spend the money. I have several custom CNC torque arms. I’ll post some photos later today.

Here's the custom for my first fat bike build on a Bikedirect POS.

Looking for my monster TA...

Finally found the photo. It’s in the parts pile somewhere. I’m hiring a young fellow to help me sort and finally have an online eBike parts rummage sale. Here’s the beast torque arm. Over 1/4 thick.

Absolutely, but I'm discounting solutions that require significant fabrication or welding. If you have metalworking skills. jigs etc. etc. you can rebuild anything. But for the typical consumer without a metal shop ... that frame is toast.

These are accessible. I get your point, however, who doesn't have access to a custom CNC? I have had a few projects done and found already developed designs and their CNC (forgot the extension) files. I gave my printer to a kid and use a number of online resources instead of doing my own prints. endless_sphere has a number of designs still available. The beast came from a fellow there.
