Torque Arm Advice

[sacko]

Looking to make or modify Docbass TA's. Apologies for the poor pictures. Ideally I would like to mount some TA's inside the frames, as you can see from this pic, there is 3mm I can remove with a grinder and file;



I would like to install the following. Please excuse the template, it is just to illustrate the idea.



Something around 9mm thick steel. Does it look sufficient?

Depends a lot on the motor and power levels you intend to run.

Doh. Apologies, completely slipped my mind.

44.4v Lipo
KU123 @ 30amp
Bafang 500W motor

Giant XTC Se

Sould be more than sufficient for that. I'm curious, why inside the frame not outside? Running a front hub in there?

I see DM hit the multiple post bug too! Something's hanging up today!

Sorry OP, dunno that motor personally...

The Bafang is from BMS Battery.

I was going to run it on the inside, as the outside of the dropouts aren't flat. I'll upload a picture..

If anyone else has any better ideas of what TA would be more suitable, it would be greatly appreciated.

Looks to me like you could just make em to fit inside that notch. It's not that small.

[sacko]

I thought of that, just wasn't sure if it was going to be enough material.

Cheers

This is a "quick" first model I made yesterday to be able to test my new setup. That's a Radon ZR Team frame. I spent hours with a jigsaw, dremel and 6 mm steel plate. I'm using it with a Cellman MAC HP kit. Did well in the first test ride.

Liking the look of that a lot. Good job

Quite adequate for the wattage you will be running, and likely a lot more.
