I did that, but I used battery - couldn't figure out how to hook up to the e-bike's 50v electrical system (plus the DC-DC converter with high enough current...)

So I am using LiPo 3S, 2200mAh. Works like a charm. I keep it at its storage voltage (3.7-3.8v per cell), and it hardly drained the battery (there is no paracitic drain). Whole thing was like $20.

I pondered doing that but thought it would agitate other road users so decided against.

		Some locales are downright itching for a reason to road rage so I don’t blame you. One thing I have to say about being a motorcyclist is that our residents in California are so considerate and have never once mistreated me for beeping, lane splitting/filtering, stalling my bike at a green light, etc.
