Dropout size is too small?

[500w_Of_Power]

I built a 500w e-bike with these dropouts, and it worked fine but seems a little small for the hub motor. If I put a 1500w motor and a torque arm will it hold?

If that's a aluminum frame bike? I would find a different bike with a steel frame. Especially if you plan to go to 1500 watts. Just my opinion thou.

I belive the frame is aluminum, yes.

No bro. Don't use that on that bike, quite simply because it won't last long and it can get you hurt beyond belief.

You need to have the hub motor axle inset deeper into the frame there so you won't have any troubles....
With what you're showing us ..you'll have Trouble.

I hope that sinks in and helps before you hurt yourself mate

The pic I posted that was a brand new aluminum bike the guy did not even get to ride once. Pulled the throttle 1 time & it snapped the rear dropouts off. It was a $550 dollar GT aluminum frame.

Thanks all for the information I will definitely not use that frame!
