Here is a little more about the Ormocar / Rammstein: https://www.youtube.com/watch?v=3S9gRflS4eY https://www.youtube.com/watch?v=cHXFa0T8WNY

As far as I know, the bite point problem is result of the low viscosity of the Shimano mineral oil. The last (three?) generations of brakes have much less oil volume and smaller diameters for oil flow. The original oil is not “thin” enough for this design. It creates an imbalance in the re-flow to the reservoir. Thus it feels like you‘ re pumping the liquid and shifting the bite point closer each time. The problem is: The mineral oil is unchanged for decades. There are millions of old type of brakes in the field, that need the old oil. So they can not exchange it. It would be a logistical and marketing nightmare to introduce two different types of oil. On the other hand, they can not improve the performance of the brakes without the design changes that lead to the reduced diameters. It’s going to be very hard for Shimano to find a way out of this… Disclaimer: I can not back this hypothesis up with any insider information, nor do I have statistical data to prove it. But I switched the oil in all of my Shimano brakes and never had the problem again.

To be fair: Bulls also released good looking ebikes for 2021. Just search for “bulls sonic ep8 2021”. Maybe this is a regional thing – release the most ugly bikes for America, keep the good looking stuff for Europe?
