I made these torque arms in a pinch to get my ebike running last year. I milled aluminum that was used in network racks in those huge lan rooms. I'm away form my bike but it is maybe 3/8" , hopefully you can see from the photos how thick it is.
I used two types with a clamping type on one side.
I also used nord lock washers. I figure these will take some stress off the dropouts?
So far these held with zero issues with my 1000watt yescomusa motor.
I am upgrading to a 45 amp, 72 volt controller, so I should be pushing around 3,000 watts with my 18s lipo pack.
So my big question is, do you think these torque arms will hold the 3000 watts? Am I putting that much more stress on the dropouts now where I should consider upgrading them?
I know that it would of course be best to upgrade them to steel. I would do that before pusing 24s. But I want to know if I can get away with these or am I taking a huge risk now?
