Aren't there usually signs indicating the maximum safe speed when that sort of thing happens? We don't have context here but I doubt there is a sign telling bikers that they should slow down. And aren't roads in general much larger and easier to see from far away, vs this tiny little ramp? You also haven't explained why the big curb is vertical instead of sloped, or why the street sign needs to be where it is. It's hard to avoid the conclusion that this thing is designed as a fuck you to bikers who don't obey the rules. We simply don't design roads that way, where it's designed to make you crash if you deviate from the standard even a bit.
We absolutely do design roads for all kinds of people to make you crash if you do not follow them. In fact, on pretty much all roads, you will crash if you decide not to follow the road, and frequently you will crash into a tree or a building. Drivers generally see this kind of design and complain about it but slow the hell down. Cyclists seem to be the same.
There is a sign ahead of this ramp saying in very big letters "BIKE LANE ENDS." It's up to the bikers to decide how they want to use that information. The sign, the ramp, and the end of the bollards marking the bike lane are visible at quite a long distance.
As for the street sign, it's a street sign. It's where the street is. It also tells you exactly where to use Google street view to get full context.
