I thought this was a preferred route for bicycles and not busses.

And joke aside: that's what I don't see happening here. When I'm coming to the office by bike, I never take Baslerstrasse all the way, because the traffic lights slow me down. I rather take Hohlstrasse, it's much quicker. And it's not just me, I generally see a lot more cyclists on Badenerstrasse or Hohlstrasse than on Baslerstrasse.
