A downhill bike with compromised safety equipment is such a recipe for disaster. A KG saved isn’t going to mean much when you wrap your neck around a tree trunk because your brakes were undersized and you couldn’t slow down in time.

I don’t like the title. Super light ebikes are great.

The article makes some good points about super light e-mountain-bikes but the title appears to address ebikes as a whole. I ride a non-MTB SL ebike but when I bought an MTB it was a muscle bike.

The extra weight of making something an ebike definitely isn’t negligible. My skinny tire SL ebike still weighs more than my MTB and the weight distribution is different.
