I saw these installed on the Arbutus Greenway today. This doesn't look in any form wheelchair, stroller, one wheel, skate board or bike friendly to me at all.
Is there any practical reason to build those barriers to justify making life harder for above mentioned groups?
I have zero experience with one wheels or wheelchairs, but these would not even pose a minor inconvenience on my bike, skateboard, or pushing a stroller.
As for why they're there, do people often try to use large motorized vehicles on those paths, like cars, quads, or golf carts? Maybe this is trying to deter that.
Bollards can be an effective filter for those
Bollards completely block. Speed bumps slow down, or discourage if there are alternate faster paths. They have different purposes and goals.
These speedbumps are on a bike and pedestrian path. There shouldn't be any cars.
Good!
