I biked around Brussels and across Belgium a few years ago and I honestly think bike commuting in Ottawa is better than Brussels. Belgium tries to emulate some of the bike infrastructure in the Netherlands but it has a long way to go. I found a lot of the routes to be inconsistent and sometimes they just sign the sidewalks as bike paths. Rode from Brussels to Mons and on to Luxembourg, and I got the impression that bike culture is probably stronger in Flanders than in Wallonia. Charleroi was bleak.
