That's a very impressive sprocket on the rear wheel.
Do you mind if I ask where you got it? Is it 25H?

Yes,there are 25H 120t sprocket.
Making use of laser cutting. Need to grind bevels on the tooth tips.

That sprocket is awesome. Great build in general.

Using regen instead of rear brake?

VERY nice job. The biggest I could find for my new build was 80 tooth but I'm fitting it to my cranks so I'm hoping it will work.

Will you need to brace it against the spokes?

Great work, especially on building your own vesc using dedicated gate drivers.

What's the noise level like with the chain?
