Copenhagen is a completely flat city which also encourages biking, but yeah, the car tax is probably the biggest reason.

  Mainz, Duisburg (Germany), Oslo, Trondheim (Norway) are not flat cities, but you see bikes everywhere anyways. It's a cultural problem, not a geographic problem.

  It's not really that flat. When the trip is >5km, all those little hills really add up.
