Built an e bike. Is it okay fir the axle to sit in the dropouts like this after being torqued down?

Those anti turn washers are NOT sufficient to hold a 3000w motor in the drop outs. You must use a good torque arm.
I have destroyed the drop outs and thus ripped the wires out of the motors (from them wrapping around the axle) on a couple occasions.
In order to hold that axle in place a torque arm is essential.
The best one i have found is by Grin Technologies, model is version 7
You can find it on Amazon for just over 100 bux canadian, and worth every penny

Yow! This is the most granular-- and useful-- breakdown of the whole hub-drive-doesn't-fit-the-dropout issue I could possibly imagine.

I feel vindicated for paying my LBS do this for my first eBike, which was a front-hub conversion, rather than just grabbing a file from my toolkit and scraping away at the dropout randomly. For a moment, I actually felt like, 'man, you wasted the money, you're just lazy, you could do that myself.'

I could have, sure, if I had known how to do it right. But obviously, I didn't, and I wasn't motivated to acquire the knowledge and skill.

With riding and with maintenance, it's the same rule, I guess: Know your limits. Bullet dodged.

I guess the important thing to realize is when you’re risking safety. Not necessarily the easiest thing to do if you’re in a DIY situation like me (my bike company went a away). Forewarned is forearmed, but I think hobbyists often learn the hard way: That’s why it’s great that we have a community here to bounce ideas off of. It’s been my experience so far here that if it’s been done to an ebike, someone will weigh in and a topic will get hot.

I could really do without the condescending, didactic posts that some folks see fit to get on a soapbox for though. They really turn me off. I know you know what I’m talking about.
